Electric pump or use the foot pump as intended or maybe a knee pump. It's useful having two hands free especially if under way.
The foot pump will fill up fine if it's below the water level. If the pump has to be above, use a simple piston pump. You'd be pulling the water up by muscle instead of relying on the spring or elasticity in the pump.
Like Diederik said the foot pump needs to be below the water level. It is not designed to suck water up it is designed to push water up.
A 12V or 24V RV water pump might do the trick for you here. Many of them have pressure switches included to shut them off at a normal plumbing pressure, usually expecting to be used with a tap and small pressure tank they keep at pressure for ready use. If the filter is a severe enough restriction a small pressure tank after it might be a bigger boon than the pump
clear tubing is great for inspection, less great for keeping nasties from growing. Even in a mild clorine environment there are still many kinds of algae that can get a foothold with enough light and while most of them are not dangerous, they can be less than palatable and will cause filters to clog much more rapidly. If you really want to keep your clear hoses (and I am not saying you don't), you should look into sleeving them with an opaque cover to keep the light out. This is also something you will want to do with your translucent tank.
(yes, even clean treated water can grow algae if given enough time. They are hardy little bastards that can set up shop pretty much anywhere there is enough light and moisture)
Noted, thanks
For the table edges, maybe a largish-bore flexible plastic tube (something like the transparent flex pipes in your water system, but larger), slitted lengthwise and slid on to the edge. Might be a pain to hold on or alternatively to remove, I guess.
My thought too. I was also thinking of using foam insulation tubing. They also make a baby-proofing product for making edges of glass coffee tables safer for firstborn children. Might work for this too.
Nice work, Alex. Cant believe this has gone on for so long now. So much effort for such a great vehicle. Keep up the great work, we cant wait to see Alan in action!
Yeah the one-man worker reality, alongside making a living, has been an education. I promise I want to get going soon. Remember too that in the background, I have to complete repetitive tasks I show you just once in videos.
@@AlexHibbertOriginals Oh I really hope my comment didn't come off as passive aggressive. I meant it all in complete good-will. Your learning and efforts to improve performance over the months are great to see, it shows the process and not just the end result. Its something we don't get a lot of on modern YT. Take all the time you need, there is no rush IMO, more time working means more videos for us!
Much appreciated!
Search for "rubber edge trim" for car doors and other thin things. It will be easy to install and removable and it will also give you somewhat of a lip to keep stuff from rolling off. It might not be enough though for a pitching and rolling Alan.
I was thinking similarly but using door weather stripping.
hi alex, love your videos! If your watersystem should be manual only, why not use a system like with those garden-sprayers, that pressurize the tank with Air and force water out via a pipe that goues down close to the buttom of the tank. so all you need woud be an air-pump, could even be a bicicle pump that just lives next to your tank and is connected when needed...., so you pressurize the tank once and water could be run from the faucet several times, when the pressure gets to low, just pressurize the tank again....
Alex, now that an electric pump is an option a small Rule bilge pump held down with 316ss threaded rod with both filters mounted vertically to the rod and the "teflon" tube outlet, wires and whatever else required for maintenance attached to the filler lid, more space in Alan and less things to disconnect for future mods. For your bench top some car sliding window bailey channel from an auto wreckers would slide on and a little contact cement would hold it in place. As far as your ballast concrete I would have added some plastic mesh as the hull impacts with crack it from the bottom up. Keep up the good work!
That's broadly my direction of travel I think, after a quick test with a non-return valve and the whale foot pump.
What if you added a one-way check valve? It would restrict the water from backflow and loosing pressure.
foot valve. I agree that that would help for sure.
It's coming along great
Can't wait to see when it all comes together. Really enjoy your videos 🙂👍
Episode 69
Nice!
nice
Maybe try an accumulator tank. Use the footpump to pressurise the system, and give it enough pressure so you just have to reprime it after use.
Reg. The missing lip on the small “table”. I would take a correct size rubber hose and cut it along its length. Then clamp it on. Easy on and eazy off. Not a specifically “romantic” solution, but cheap and easy and should hold on well enough, for it’s critical tasks.
Watched this whole playlist at like 1.25 speed in no time! Amazing series but you should get a hand held router so easily take off your edges for thick plastic and wood etc. no more worrying about bumps
Can also obviously choose a bigger router bit for larger rounds on edges
Cheers Ryan
Perhaps the clear tube between the pump & filter needs a one way valve so that after you press the pump you are not sucking any water backwards into the pump. The one way valve should be put as close to the pump as possible.
Some people suggest this, and others refute it. Neither offer their reasoning. So, I'll have a try!
@@AlexHibbertOriginals I only thought of it as I watched you pumping & there was an air pocket in the water tube that it was going forward & then backwards.
@@AlexHibbertOriginals The pump already has a valve. You can tell because water does not flow back. Without a valve it would not draw up any water at all.
I would try that foot pump with water in it before you decide to put it under the worktop and push it with your hand!!!! And while I'm on a negative role it best to ballast the boat when it's in the water because adding ballast is easier than removing it just a thought!👍
So I wonder how many other people write their comments before they finish watching!😂
You're right on the ballast. I've not gone crazy with it, and there'll be a lot of moveable supplies to perfect weight distribution along the way.
30mm hose split to cover the edge.
I would also suggest cutting a very shallow kerf 6-8 mm from the edge on the bottom of the shelf to assist the hose in staying put.
For your surface edge rolling woes, i suggest a rubber edge trim of the 90 degree option. Simply held down with double sided sticky for easy removal. This will, of course, mean using a fresh layer of double edge sticky after a laborious removal of the old. BUT... it is a versatile and, several times over, re-usable material
Alex look for a "Double Action Galley Pump" there are versions for boats and versions for RV's and campers. That should help with the water pressure issue.
I wonder whether it would have the umpf to draw water through the filter AND handle the 1.5m elevation from source.

See if you can use a hand cranked fuel / diesel transfer pump, they can lift a large distance and the correct sized one will give you a good system pressure to conquer the charcoal filter.
They are great, but hard to find in small sizes.
Another great episode
i know it's not in the budget, but i came across ripe energy the other day. they have a turbine generator that can output 8kw and it's 77x40x45cm and it weighs 25kg.
pretty remarkable.
For the lip, I can't help coveting a single nicely steam-bent wooden affair fixed with handsome brass screws. Or I suppose you could use seated brass bolts with wing-nuts on the underside of the perspex that would facilitate quick and easy removal.
I definitely have the spare time to do that. Without doubt.
@@AlexHibbertOriginals hee hee, a guy can dream.
voice over alex always sounds like he is reading lord of the rings, even when talking about water fittings.
Quite right too.
totally love this
Your pump will do the job, but you need a one way valve, or a 'foot-valve' in the pick up end, to stop gravity trying to drain it straight back.
no, that's not accurate. A valve would not make a difference. The pump should be low to function properly.
Hi Alex, personally I'd try a small-ish 12v diaphragm pump. That can suck up the water from the tank and provide plenty of pressure to get through your filters. Perhaps have the foot pump as a back-up.
12v may be the saviour here, sadly.
The plastic tubing might be flexing to absorb some of the pressure from the pump.
a magnetic rubber strip along the edge of the table might work, using something like magnetic drawer latches to keep it on
those anti stuff rolling off edges are called fiddles
If you add lead to your cereal, you will soon experience heavy breathing... Greetings from Sundsvall Sweden! ❤😀
I think it's not an issue with the pump but with the hoses you use. Most of the effort of pumping is going into hose deformation. Try testing with supply lines or reinforced tubes.
This is quite possible.
great video 🙂
just called my local bookstore and ordered "Polar Eskimo" ... expexted delivery to the store in 21 days ^^;
Goodness! Where's that?
@@AlexHibbertOriginals Germany, they have to import it
edit: the import is free of charge
@@AlexHibbertOriginals also books are price-bound to protect local stores (which I approve of)
You should put the pump on the floor so you can pump when you need both hands for something
A lot of hose travel for that. And limited floor space.
Nice work Alex! I might be missing something, but why couldn't you use a standard squeeze style pump? I feel like that could work fine if you can find one that gives you decent flow. Maybe even have it connected in series with an electric pump, in case it fails you can remove it without having to mess too much of the water setup. PS: I just got your sticker in the mail, its officially on the laptop lid.
Happy the sticker arrived!
i wonder if a hand crank pump would be better than a push style pump, issue is just where to mount it i suppose
Yeah I've used them before. Great, but all so large!
@@AlexHibbertOriginals i wonder if someone makes one w/ a "flat crank" where its just a wheel w/ a knob to turn it ontop of a gear/impeller pump housing roghly the same size and shape as that second pump that you used in your testing later in the video
As a long-term boat dweller, I'd go with @jonnypowell1998's comment - it's much more convenient to have both hands free and pump water with a foot. The foot is more powerful, too, and won't get tired when filling up a large pot/kettle/bowl.
Noted!
2x filters in parallel offer considerably more filter life than just double.
In the vid (link below) starting at minute 26, Jon explains why with a graph. He had residual rust in his fuel tank after a thorough cleaning that was still blocking filters in no time but I think 2x filters in parallel give you about 4 or more times filter life than just one filter, for only double the cost. Cost wise it is far more efficient.
th-cam.com/video/DWNT_htKWpg/w-d-xo.html
Also there's another benefit of parallel filters pertinent to your foot pump imbroglio.
I found this on a plumbing site:
*"Plumbing filters in parallel increases the flow capacity and reduces the pressure drop across the two combined filters."*
Thanks. I'll rig up Mk2 and see if the filter is happy. I may add a couple of tees to create a parallel even if it seems one is fine. Space may dictate.
Oh yeah.. I seen new electric devices on the Electrical panel .. that surely will be on a new episode * humming the AHO theme-somg *
try to wash your hands while pumping! Use a foot pump/knee pump. The double-action one
Point taken, although there's no sink - so it's not a hand washing station. More a simple water supply.
I’m not sure why your not using a small 12v pressure pump like the ones used for pressure spraying weeds. There cheap and have a built in pressure cut. They are very good for using what your wanting to do and cheap enough to carry a spare
An aim to avoid running 12v down to this zone. But I may end up without a choice.
@@AlexHibbertOriginals honestly I think it’ll be so much easier to get the water with an electric pump but I do understand. Do you have an idea for when you will launch and set of on your adventure?
Should have just bought a faucet with a built in hand pump. they are designed to pull water up to the faucet, where foot pumps are designed to push water up to the faucet.
I've ordered one as a test - they just look a little fragile.
So I may have missed why he couldn't mount the hand pump horizontal between tank and cabinet? Looks like space and all have to do is a sideways motion . Kinda like pulling a rope waist high type motion
It's deceptively wide. Sadly wouldn't fit and I might have the same refill issue as the other foot diaphragm pump.
@Alex Hibbert Originals thanks for reply doing dishes and watching video occasionally miss things . I enjoy your attention to detail and thought processes on everything . Alot of people would just slap something together. But alot of people don't have as ambitious plans as this vessel has ... blue skies and good luck
I'm sure there's a reason you're not using the foot pump as a foot pump. I'm curious to know it. It does seem that it would be useful to have both your hands available while pumping water to the sink.
Running lines all the way from the bottom of inside the tank to the top, to the floor again, and then up to the work surface. About 5 metres of travel.
@@AlexHibbertOriginals I bet that would work just fine. Going up and down almost cancels out. The pump would fill up faster, being under the water level and it would push the water up easily. Seriously. Please give it a try.
Looks like that pump is not working as there is no one way valve to stop it sucking the water it just pumped out. If you want to avoid a electric pump, may be worth trying out with a one way valve just before the filter.
I'll give that a crack.
Non return valve in the feed side?
Will you please make a little longer videos they seem to go bye to quick.
Ha! Slow down the playback.
Is it possible to use a sort of wankel style pump? Rotating handle on top of it more continous flow?
They're all enormous.
@@AlexHibbertOriginals Oh..well then.
I would first try a good quality foot pump and actually use it with your foot. Also have you ever tried washing your hands with just one hand?
The distance of travel for a foot pump here would be about 5 metres of flow. There's not going to be a sink or greywater tank, so not a hand-washing station.
@@AlexHibbertOriginals Ah ok I must have missed that part :P but would you not need a sink of some sort?
Yes, but probably in the 'wet' end of the boat, near the hatches, for rinsing and washing.
What are you doing! It's the England game on Channel 4!
I don't have a television. And if it's football, no thanks!
Well you know why people are complaining right. Cuz you're doing it wrong.!
It's not ingenuity to use a foot pump as a hand pump. It's literally more difficult. That's the function of having it be a foot pump.! So if your hands are full or covered in shmutz. You can access the water. Without using your hands. Regardless of manual hydrolysis.
But I guess you find it acceptable to never wash both hands at the same time.!
Not to mention. You could easily just pressurize the tank with air. And have it come out all by itself.!
Like you swear making it difficult on yourself is in some way better. Nop. Just in some way stupider.!
Not to mention. You're holding it upside down. When you're testing it. And even when you're holding your right side up. You can see it starts to come out. Which if you're only washing one hand at a time. I guess that's fine.
But if you've ever used a foot pump before. You know it can produce at least three times as much flow. If you are rapidly pressing it with your foot.
But then you mention you might have to get some sort of electric pump. Which again is IDIOTIC.!!!
ALL YOU HAVE TO DO. IS PRESSURIZED THE WATER TANK WITH AIR. You can do that with a bike pump since you like making things so difficult.. And it will last for as long as the water does.!
This is what really perturbs me about some of your videos. I'm watching. Because I expect you to do clever and useful things. But sometimes. Good grief man.
I think maybe you've been traveling too much. Or maybe you haven't put that much thought into it. Or maybe that's why you ask for assistance a lot from the comments.
I don't know Just seems like nails on a chalkboard to me to see a bad configuration.
It fascinates me how a short TH-cam video about water pumps can wind people up to the extent that barely any of their sentences make sense.
@@AlexHibbertOriginalseah. If what I have said here doesn't make sense to you. I think you have bigger problems.!
Also if you can recognize that these little TH-cam shorts are capable of causing trepidation. Then you are guilty of trolling your own damn patrons, subs (No pun intended) and viewers.!
Classy.!
But it's Engerland. Harry Kane and all that.
A Jigsaw is boring, at worst it'll make your hand numb with a recovery period measured in seconds. An angle grinder is for brave barbarians. It'll take off a finger, a hand, or your neighbors Regional champion Crimson bunted flightless Finches. Oddly, if they could fly, they probably could have avoided the spinning wire brush as it lept off the hood of the car at 600mph.
Clearly a proponent of rotation over oscillation.
I mentioned it before, and while watching this was surprised as to what you attempting, that an RO unit, with an electric pump, might be the way to go. It can be engaged at any time and would have a pressurized a tank. You can choose the pressure and still use your refrigerator filter. Personally, a block filter scares me and I would at least use a granular carbon filter, but that's my opinion. You never know where you'll end up and having something that can filter salt water is a plus. Besides, you can set up the small electric pump as a pre-pump that can be directed to just filtered water, RO water or just direct pumped into the sink freshish water can be used. Just a thought and a ball valve adjustment. A pressurized RO tank filled with water is a great ballast and is generally always full if the pump is engaged. A manual pump is a great backup and another valve adjustment away. Just sayin. Water is the most important. Also, I always love your comedy. Cheers
Cheers - I always read in full and consider ideas, even if I don't adopt 100% of them! Reasons are often cost, and available space.
@@AlexHibbertOriginals I'm certain your finished design will be overkill, no matter what you decide. As Chef John of Food Wishes might say; After all, you are the Al Capone of your water throne. Best
