This is the way to do it. To me, the float switch should be separate from the switch on your dash. Float switch is for when the boat is left on the water unattended. Great video
I am a mechanic by trade and you are correct, this is a very simple circuit which I've done many times. With that said, I know you are trying to make it as clear as possible for the viewers but you're really not explaining it well enough to make it understandable for beginners, you need to do one wire at a time instead of just saying "hook it here hook it there" because some people aren't going to understand it or get it. You made an awesome diagram on that board so maybe slow down and one wire at a time pointing to your visual. I would like to thank you for sharing your time and knowledge with everybody, you are very much appreciated 👍🏻.
Great follow up to your first video. I ran mine slightly different due to my setup on my fishing boat. I went pos bat, fuse, pump, neg split 1 through float to switch top position, back to ground, neg split 2 to switch down position back to ground. Much less wiring for me this way and taking advantage of 3 position switch.
Finally someone explained the installation of a float switch in easy terms. My boat manufacturer said they don't add the float switch to save the consumer money. I would rather pay a few dollars more for the switch than find my boat sunk at the boat dock.
A couple of thoughts... it's still a good idea to have a manual switch that can disable the float switch... in case it gerts stuck on (if some detritus gets stuck under the float switch etc), and so it can't turn on while you're refueling, connecting gas cylinders, etc as the float switch's contacts and the pump's brushes will make a very small spark internally and of course the pump's located at the lowest point where fuel/gas vapours will collect. Also, if you fit a small light to the common wire that connects both the manual & float switches to the pump you can have a "pump running indicator" which will alert you to when it automatically turns on. If your boat's filling up more often than it should be due to a leak or something it's not a bad idea to have some sort of indication that the pump's running, and if you turn it on manually and it doesn't light up it alerts you that the fuse is blown or that there's some other problem. You can easily mount the light next to the manual switch. (I also put an "automatic active light" next to my disable switch to remind me that the float switch is activated. I also fused both the automatic and manual circuits individually so if one fuse blew I still had the other option.)
Like a three-way manual. You can also house the float so debris can't get stuck under it. But, I've seen floats stick open from grunge build-up at the hinge or even from just their own friction.
The manual switch should be one that lights up when it's "on" and the pump should energize a tell-tale light at the helm when it's operating. Manual switches can be accidentally turned on which is something the operator needs to know about. If the bilge pump stays on for a long time via it's float the operator needs to know that something is either stuck or there's a big leak somewhere.
Can you zoom in on the connectors ( closeup) ie eg.the pos from switch and pigtail to 3way switch ,hard to see... I had to wire 2 negatives into 1female connector...after the instructiions said" Connect the neg wire from pump to neg terminal on float switch. Now Connect neg terminal of battery to neg terminal of switch... Helpful if more closeup of actual connectors thx great video... And of course instructions are not always diagrammed properly
For safety, mount a second switch a little higher than the first in parallel with the first so if the first doesn't activate, the second one will a little later. Or hook the second switch to a second pump and add a buzzer wired across the second pump's leads to warn you when it comes on. Cheap insurance for an expensive boat.
Do float switches never stick closed? That is, do they never fail in such a way that the pump is stuck on? A three-position switch might be a good idea, toggle on/off/auto. And I'd want a counter or hour meter, so if I was away from the boat I could know if the pump has been running.
The wiring illustrated on the blackboard will NOT work. The float switch will not work because the circuit is open at the manual switch. The manual switch will not work unless the float switch is closed. The white board is correct and will work perfectly. The manual switch circuit has to by-pass the float and go direct to the bilge pump and the charge to the float must by-pass the manual. This can also be achieved with a three-way switch (manual-off-auto). I put the manual breaker (fuse) in the line immediately AFTER the switch and the breaker (fuse) for the float close to the battery (before the float). The common positive to the pump contacts the manual and float feed at a terminal block or a three-prong watertight plug (never butt connect them).
Quick question. On my boat the bilge pump works when manually switched on but not from the float switch. However, when the system is plugged into the wiring harness for the other bilge it works. in other words, the float switch works fine, but not when connected to one of the harnesses. Very confusing.
It'd be interesting if you could show how to waterproof a 3 wire splice ,as is required for auto override. Pumps and float switches are never supplied with enough cable to reach somewhere dry in commercial fishing boats fish hold settings where there is always water dripping through the floor from melting ice , in such settings automatic pumps are ideal but manual override is also required for all the reasons you outline . Thank you.
Regan my son got a special electrical clip over the main bilge pump wire which the female spade clip is crimped to the wire on the float switch which you push straight onto the male clip & the female clip has heat shrink on it & I completely wrapped over with black electrical tape & I hunted high & low for that type clip & was lucky to get one like that & it saved me cutting the wires & if I couldn't get this clip I would have got a complete T water proof connector from AliExpress Store & the clip I got is a T one as well but wasnt water proof but wrapped with electrical tape should work well & wrapped over electrical conduit & hopefully that's helped & it's pretty dry underneath where wires are Kind Regards Peter
Good video brother… asking about fuse size its confuse me Little bit .. I know that the fuse should be less than Amp max current … they mentioned in the manual it should be higher ?? Can you explain it please ? Thank you very much
Hi Mohammad, thanks for your question - I will try to answer it with an example. First thing to say is that fuse is to protect when things go wrong. So normally the fuse will not blow. Now for example we could have a bilge pump that normally takes up to 7 Amps. So in the normal situation the pump takes 7 Amps at most (when starting up, or when working hard) or when working less hard around 4 Amps. So the fuse should be rated above 7 Amps otherwise it will blow every time you turn the pump on so we could have an 8Amp or 10Amp fuse. So what could happen when something goes wrong ? The pump could get jammed or seized up and cannot turn. Then when you turn the pump on it takes more current than usual - maybe 12Amps or 15Amps and in this situation it would get hot and maybe burn out or melt the wires (bad!). Here is where the fuse comes in and as soon as the pump takes more current than the fuse rating, the fuse blows to keep everything safe. I hope that answers you question? All the best, Richard
Have an existing on/of switch and pump. Pump has brown and black. Float has brown and a brown/white wire. I ran fuse to battery + to brown/white on float. Other float brown wire to brown on switch. No power. Any ideas?
Hi Bill, thanks for your comment / question. I can't make comment based on your wording as I might mis-interepret what you have done. If you send me a photograph though to info@boatfittings.co.uk I could try and make a suggestion. All the best, Richard
Hi Sir how I'm going to wire up my float switch is by putting one from the float switch to the positive wire to the bilge pump & the other wire on a waterproof fuse holder & goes directly to the positive side of the battery as the other positive wire on the bilge pump already goes to the switch on the dashboard panel & it never had a Float switch put in the 2015 6.20 metre cabin fiberglass boat only the 1100 gph bilge pump was installed & it should have had a float switch installed in the first place as the boat I brought new had a bad Design Fault the bilge pump outlet was at the back of the boat which should have had the bilge pump outlet up at the side of the boat as when I get more people in the boat I noticed that I couldn't get the boat on the plane & when I got back to the boat ramp & got the boat onto the trailer & drove up the boat ramp & park at the vehicle & trailer up the hill well away from the boat ramp I took the 3 bungs out the middle bottom bung that I took out there was so much water coming out it wasn't funny & took a long time to drain out & even my youngest daughter said to me that's a lot of water coming out of the boat & shouldn't be that much amount of water coming out from a near new boat & it had me stumped why there was so much water coming out & it wasn't until later down the track that I found that the water was coming in from the bilge pump outlet & the it also had damaged the toilet pump NZ $300.00 later as the toilet wouldn't work & I had to clean out the toilet as it wouldn't flush & when I got the toilet pump out it was all rusted up as the bloody water that was coming in from the bilge outlet had gone right up the the bow of the boat & got into the toilet pump & now I've got a float switch that's going to stop the water going right up to the bow & later down the track I'm going to have the bilge pump outlet up high & at the side of the boat & have it professionally done & have the old bilge pump outlet hole professionally blocked off pissed me right off well having that done right & I will never never have that problem again & the only way I knew the water was coming in from the bilge pump outlet was I got the garden hose & I didn't have the tap on full running & just trickling in & I had the centre bung out & you should have seen the water coming out the was a lot of water coming out of the bung hole & so having the float switch installed the water that comes in through the bilge pump outlet will gradually pump the water out again Kind Regards Peter PS very good of you Sir for showing how wire up a float switch & on my dashboard panel there no way I can install an automatic switch but will automatically switch it's self on & I'm still be able to switch it on manually as well but most of the time when I turn on the main switches the float switch will be fully Automatic when I'm out in the boat & I get some spare money I will then change the bilge pump outlet over up to the left hand side of the boat & have the old bilge pump outlet hole completely professionally blocked off which will completely solve that problem I can't understand why the boat manufacturer didn't have the bilge pump outlet going up to the left hand side of these boats & there are a lot of other boat Manufacturers have their bilge pump outlets up at the sides of the boats so no water can go in through the bilge pump outlets
@@BoatFittings Hi Richard Peter here again I apparently had put the new bulge pump outlet higher but apparently not quite high enough & I went out in the boat on last Sunday New Zealand time & when you get the boat on the plane the new bulge pump outlet goes under the water & let's water into the hull & operates the float switch which switches on the bulge pump & you slow down in the boat the bulge pump outlet is out of the water an a mistake on my part & will have to take the outlet fitting off & have that hole blocked off by the Fiberglass repair guy Rod to block that hole off & I rang Rod yesterday & he is going to quote me $200 to $300 to block the hole off bugger more expensive & the first bulge pump hole outlet to have blocked off was &189.00 & now it's more money Bugger & the other new bulge pump hole outlet has to go up another 5 to 6 inches what a bugger & it will be completely out of the water so no water can get into it a BLOODY BIG MISTAKE ON MY PART & then it will be all sorted & it a stupid place in the first place for the boat builder to put the bulge pump outlet at the back of the Smuggler Sport 6.20 boat in first place where water could get into it all the time & it was only the bulge pump was installed & that finally destroyed our toilet pump & that was $300.00 later & now it costs me $200 to $300 to have the blocked off bugger & that money could have gone towards fuel for the boat as petrol is not cheap anymore it is 2.75.9 cents a litre for 91octane fuel & other parts in Auckland New Zealand you could be paying $2.86.9 a liter for 91octane fuel & I have a 200 liter tank in the boat & it is nearly down to half a tank of fuel which is not cheap to fill the tank & I understand the fuel prices are going to up around Christmas & our cost of living is already high in New Zealand & will even go up more some parts in Auckland New Zealand Diesel is already at $3.00 at a liter Bloody really expensive & that's why our food prices are so high & everything is else is going up as well & you have a Lovely Nice Day or a Lovely Nice Good Night Richard Kind Regards Peter
Hello, I've subscribed, I just brought the seaflo 4700 GPH and have no idea what cable I need all I k ow is its 14 gauge but from watching other you tube videos there saying copper is a no go with these pumps... This is to empty a swimming pool and will be connected straight to a battery could you help me in anyway or give me some guidance because I'm genuinely out my depth any help would be massively appreciated
Hi thanks for your comment and question. With regard to the wire I am not saying copper is a no-go, but there is an advantage in the long term for pre-tinned copper as it will not corrode. If you cannot get pre-tinned then normal copper wire would be ok. The most important thing when choosing the wire is that the gauge is thick enough. Thicker is not a problem, but thinner can lead to over-heating. I hope that helps a little.
Great video I had the same worries about float switch failure so this helps a lot! You referenced another video that will include a switch panel, is that still in the works? Also, what size fuse should we use if the pump says 4amp but the switch says 20 amp. Tsunami T800 bilge pump with Rule 40A float switch for reference. Thanks again!
Hi thanks for your comment and questions. The fuse should be selected based on the pump as it has a lower rating and you are therefore wanting to protect the pump from over-load. Yes the switch panel video is due pretty soon - hoping to get part 1 out in the next 10 days. All the best, Richard
The amp rating for the switch or the float is the current flow it can handle without burning up - it's essentially irrelevant to the appliance circuit. What you want is the proper amp rating for the appliance circuit. If your pump can draw max 8 amps, use a 10 amp protector; if it can only draw 4 amps use a 5 amp protector. You're never come close to burning up a switch.
Great easy to understand vlog, Thanks. What are your thoughts on integrated float switches in the bilge pump? Or go for both for the £25 quid for an extra bilge to guard against single bilge failure in parallel with the existing separate float switch and bilge pump here? Overkill and a more things to fail of worth it as it's not much more money for peace of mind.
Hi Jon, many thanks for your comment. I am glad you asked this question, I am in favour of many bilge pumps for added redundancy and safety, I would suggest at least 2 and sometimes 3 or 4 or more are appropriate for larger boats. I am quite a fan of pumps with an integral float switch as well. Richard
I wouldn't own a boat with only one bilge and I always push my customers to add a second one ESPECIALLY if the vessel lives in the water. I also go a little overkill on the GPH cheap insurance if you have a thru-hull fitting or similar type failure.
Separate float and pump only. Why? Because it's cheaper and easier to replace the bad one alone. If your float fails ($30); if your integrated detector goes bad, you have to replace the whole works ($200+).
It would make sense to explain what a "larger" boat is. Up to 23 ft or so, one pump can more than suffice depending on its boat design and conditions of use. Twenty-three to 30, probably better to have two pumps. Thirty ft or so and up, go three. And, so on. @@BoatFittings
If a thru-hull goes, you had better have a whole lot of GPH (that you're not going to get from even two or three typical pleasure boat pumps) and plenty of battery power (also unlikely). Keep an eye on your boat.@@a1aadvancedmarine88
Hi thanks for your question. Normally the pump should have a label showing the recommended fuse rating. If it actually draws 15amps then the fuse needs to be a bit higher -eg 20Amps. As for wire gauge a quick google on 'wire gauge vs Amps' should bring up some good results. All the best, Richard
Correct about wire gauge and appliance amp draw, but remember that TOTAL CIRCUIT LENGTH is important as well. A pump that is 4 ft from the battery (8 ft circuit) can get by with a smaller gauge wirenthan the same pump that's 24 ft from the battery. @@BoatFittings

Hi thanks for your comments, and absolutely worth spending a few dollars more!
Finally is right!!! We were having a misunderstanding about the two wires on the switch both being positive. Makes sense now! Thanks!
Great video. Clear and concise . Thanks for sharing.
Do NOT trust a float switch to keep your boat from sinking. You have to keep an eye on a wet-slipped boat.
A couple of thoughts... it's still a good idea to have a manual switch that can disable the float switch... in case it gerts stuck on (if some detritus gets stuck under the float switch etc), and so it can't turn on while you're refueling, connecting gas cylinders, etc as the float switch's contacts and the pump's brushes will make a very small spark internally and of course the pump's located at the lowest point where fuel/gas vapours will collect. Also, if you fit a small light to the common wire that connects both the manual & float switches to the pump you can have a "pump running indicator" which will alert you to when it automatically turns on. If your boat's filling up more often than it should be due to a leak or something it's not a bad idea to have some sort of indication that the pump's running, and if you turn it on manually and it doesn't light up it alerts you that the fuse is blown or that there's some other problem. You can easily mount the light next to the manual switch. (I also put an "automatic active light" next to my disable switch to remind me that the float switch is activated. I also fused both the automatic and manual circuits individually so if one fuse blew I still had the other option.)
Hi thank for your comments. I think you have made some very good points there, and I like your thinking. Much appreciated.

Like a three-way manual. You can also house the float so debris can't get stuck under it. But, I've seen floats stick open from grunge build-up at the hinge or even from just their own friction.

The manual switch should be one that lights up when it's "on" and the pump should energize a tell-tale light at the helm when it's operating. Manual switches can be accidentally turned on which is something the operator needs to know about.

Thank You for a simple Informative & to the point tutorial👍🏼👍🏼👍🏼
Glad it was helpful!
The float switche will burn out pretty quickly if it's carrying too many amps. Best practice is to use a relay for larger pumps.
how will I connect the 3 way splice waterproof for saltwater use?
For safety, mount a second switch a little higher than the first in parallel with the first so if the first doesn't activate, the second one will a little later. Or hook the second switch to a second pump and add a buzzer wired across the second pump's leads to warn you when it comes on. Cheap insurance for an expensive boat.
Good advice. Floats are notorious weak links - they fail frequently.
Do float switches never stick closed? That is, do they never fail in such a way that the pump is stuck on? A three-position switch might be a good idea, toggle on/off/auto.
And I'd want a counter or hour meter, so if I was away from the boat I could know if the pump has been running.
They can stick in either the on or off position - and, often do.

I would advise against a three wire splice. Use a terminal block that you can render water resistant or a quality, waterproof plug.
Always go with a plug that's engineered to be water tight as opposed to heat-shrinks and (or) tape - neither is ever water-tight.@@petermorton2869

if i’m just going to use the manual switch without the float switch… would i still need a fuse? sorry i know nothing about any of this haha
I would always fit a fuse, as a precaution,
Would there be any problems if both switches went on at the same time?
Hi thanks for your question. There would be no problem at all if both switches went on at the same time.
Hello, I've subscribed, I just brought the seaflo 4700 GPH and have no idea what cable I need all I k ow is its 14 gauge but from watching other you tube videos there saying copper is a no go with these pumps... This is to empty a swimming pool and will be connected straight to a battery could you help me in anyway or give me some guidance because I'm genuinely out my depth any help would be massively appreciated
Hi thanks for your comment and question. With regard to the wire I am not saying copper is a no-go, but there is an advantage in the long term for pre-tinned copper as it will not corrode. If you cannot get pre-tinned then normal copper wire would be ok. The most important thing when choosing the wire is that the gauge is thick enough. Thicker is not a problem, but thinner can lead to over-heating. I hope that helps a little.
Great video I had the same worries about float switch failure so this helps a lot! You referenced another video that will include a switch panel, is that still in the works? Also, what size fuse should we use if the pump says 4amp but the switch says 20 amp. Tsunami T800 bilge pump with Rule 40A float switch for reference. Thanks again!
Hi thanks for your comment and questions. The fuse should be selected based on the pump as it has a lower rating and you are therefore wanting to protect the pump from over-load. Yes the switch panel video is due pretty soon - hoping to get part 1 out in the next 10 days.
All the best,
Richard
The amp rating for the switch or the float is the current flow it can handle without burning up - it's essentially irrelevant to the appliance circuit. What you want is the proper amp rating for the appliance circuit. If your pump can draw max 8 amps, use a 10 amp protector; if it can only draw 4 amps use a 5 amp protector. You're never come close to burning up a switch.
Great easy to understand vlog, Thanks.
What are your thoughts on integrated float switches in the bilge pump? Or go for both for the £25 quid for an extra bilge to guard against single bilge failure in parallel with the existing separate float switch and bilge pump here? Overkill and a more things to fail of worth it as it's not much more money for peace of mind.
Hi Jon, many thanks for your comment. I am glad you asked this question, I am in favour of many bilge pumps for added redundancy and safety, I would suggest at least 2 and sometimes 3 or 4 or more are appropriate for larger boats. I am quite a fan of pumps with an integral float switch as well.
Richard
I wouldn't own a boat with only one bilge and I always push my customers to add a second one ESPECIALLY if the vessel lives in the water. I also go a little overkill on the GPH cheap insurance if you have a thru-hull fitting or similar type failure.
Separate float and pump only. Why? Because it's cheaper and easier to replace the bad one alone. If your float fails ($30); if your integrated detector goes bad, you have to replace the whole works ($200+).
It would make sense to explain what a "larger" boat is. Up to 23 ft or so, one pump can more than suffice depending on its boat design and conditions of use. Twenty-three to 30, probably better to have two pumps. Thirty ft or so and up, go three. And, so on. @@BoatFittings
If a thru-hull goes, you had better have a whole lot of GPH (that you're not going to get from even two or three typical pleasure boat pumps) and plenty of battery power (also unlikely). Keep an eye on your boat.@@a1aadvancedmarine88
Hi what gauge wire can you with the pump and float switch it draws 15amp. And what amp fuse can i use
Thanks
Hi thanks for your question. Normally the pump should have a label showing the recommended fuse rating. If it actually draws 15amps then the fuse needs to be a bit higher -eg 20Amps. As for wire gauge a quick google on 'wire gauge vs Amps' should bring up some good results.
All the best,
Richard
Correct about wire gauge and appliance amp draw, but remember that TOTAL CIRCUIT LENGTH is important as well. A pump that is 4 ft from the battery (8 ft circuit) can get by with a smaller gauge wirenthan the same pump that's 24 ft from the battery. @@BoatFittings
