You did a decent job. A few suggestions for you. First I would have run a piece of rubber expansion pipe in the vertical section (after the pee trap) which offers some room should the pipe move vertically for whatever reason. Next, your drain pipe is going to fill up with grey water to whatever height it is in your grey water tank because you entered the bottom of the tank with it. Not a huge deal, but something to think about. Third, you have no way of disconnecting your tank in case it requires servicing or replacing. You will need to cut off your pipe and re-glue it back together again. Fourth, the bigger your drain pipe at your electric drain valve, the easier it is for food particles to get out or at least not get stuck. Fifth, there is a lot of strain on the base of your drain at the tank. The weight of the drain valve, especially when going down bumpy roads will stress it even more and could cause it to fall off or crack over time. I would recommend finding a way to support that weight. Sixth, I would consider having metal protection on each side of the toggle switch so that it doesn’t get hit as you walk in or out or perhaps get caught in a belt loop or by something you are carrying in. Next, I would caution against using loomex (romex in the US) or any other type of solid wire as it tends to break. Stranded conductors are a better choice. Finally, I had the volume turned down while watching this, so you may have dealt with this issue, but I hope you angled the pipe down towards the grey water tank once outside of the van rather than having it fairly flat. Considering that your entry point into the grey water tank from your sink is at the bottom instead of the top (I understand why you did), the steeper the angle down your pipe goes from your first 90 below the van floor, the better off you would be because there would be less water in that pipe and less pooling should you be parked facing downhill. My apologies if I am wrong on any of my thoughts, but just shared them in the hopes that they are helpful... Enjoy the adventures!
I would add one other point, you should have a manual valve before your motorized ball valve in case ball valve fails which mine did. I had a tank full of gray water and no way to drain. I ended up removing sink drain line and siphoning gray water out through. Not fun!
Great additions to this video. I caught the low entry point of the waste line into the tank, but missed most of your other points. I intend to take all of them under consideration on my current build.
I have the auto reverse ball valve instead of the reverse polarity. When power is removed, it auto closes - but it actually doesn’t use power at all once closed, so I actually think it’s a much simpler setup. Just FYI!
increase your drain to 3/4 or 1" not 1/2" and use whirsbo waterpipe. (rent the tool from homedepot) - use abs glue on abs pipe and where you use your 90 after your p-trap, replace with a T and off the top of the T use a cheater vent. (cheater vent is a check valve airintake)
@@albertanasoul by cheater vent i mean - "air admittance" after you connect your ptrap. you use a T and off the Top of the T you use a "air admittance valve" or a cheater vent you glue with abs glue on your pipe. the height doesnt matter (just go as high as possible) because it has a internal check valve. all it does is let air in when you use your sink so if siphonage happens the air admittance valve opens on negative pressure and lets air in to save your ptrap from being siphoned out and running dry. because then you get sewage gas smells.
Good setup! Not trying to be negative but the only problem I see is that due to the lower input pipe, you’ll only be able to use less than half your tank due to fluid dynamics. Your level will never go above the top of your input pipe since the system is not pressurized. You gave me some good ideas as to how to install mine! Thanks!
Good sir, you are indisputably wrong. Pressure will equalise in the system, the system does include the inlet pipe. Hence the tank can be filled to the brim once water starts building up in the vertical pipe.
I’ve looked at a few of these gray tank videos. They all show the e-valve mounting on a straight extension from the tank. That creates a relatively long, unsupported lever. Would it be better to have some support for that lever or is it so light that no support make a difference? Also, why not just use a nipple to connect the valve directly to the tank?
You may be able to do it with a nipple, it's going to basically the same thing though. It may look like a pex extension is being used and it could flex but in reality the pex piece is the minimum length i could use with the two male adapters. So basically that little piece of pex has solid brass inside of it. The valve is pretty sturdy as it is, I didnt feel it needed any extra support after tugging on it but you could add something if wanted.
It's in a vehicle, vibrations will always have an effect, always support either side of any mass and double up on number of supports generally, I'd also be adding a clamp to the drain as it passes under the frame rail. 😀
When I click on the link for the switch for the dump valve, I get a listing for 6 switches that are different from the original e-ten switches you originally had listed. Not sure WHICH of multiple switches with "reverse polarity" shown on Amazon to buy. Is it the on/on switch? Thanks for the great videos.
Does it matter which positive and negative for the valve align with the positive and negative from the battery? Or as long as the valve positives and negatives are criss-crossed on each end it's good?
Can I install this hot water heater in my Ram Promaster? I can get an inverter, but it seems that I might need a breaker box? I would have an on and off switch when I’m not taking a shower or I need to just wash my hair in the sink.
Yes you can add a water heater. You have a few options. You can do an electric water heater like i did on my last build here th-cam.com/video/U3-FfbOsG8I/w-d-xo.html if you do that you would need at least 300 amp hours of battery and an inverter sized to handle the load or you can do a propane tank less water heater out the back of the van like I'm going to do on my current van. I would recommend this option and I'll be showing it in my next video.
thanks for the lesson. I'm extrapolating this into two 10 gallon tanks. you haven't had any issue with the bolts sticking up rupturing the tank over time?
love the remote drain feature, easier than I would have thought. So I'm wondering if larger food particles would get stuck over time in that smaller drain pipe though?
The sink comes with a little strainer filter that is like mesh to catch any food particals. It pulls out to easily clean. Anything that gets past that then yes you would need to clear the clog
Great explanations and detail. Thanks! Can you tell us what you think the ideal tank size is? Is 5 gallons too much or too little in practical use? If more is better, how much more? I'm aiming at full-time use and thinking of a single 25L tank, with baffles to minimize sloshing. If that's overkill, can someone explain why? Thanks again.
I think it depends on how you use your van. For me this was the perfect size. But I always just leave the valve open and drain out the bottom of the van unless I am somewhere that it wouldnt be appropriated to do that, then when I leave I empty it by opening the valve. So i never really drive around with a full grey water tank. So i think it depends on how you use it.
From the way you connected the switch, i think the valve is getting power all the time, and the switch is only reversing it. one position is + - , the other is - + . is that correct? but this is a normally closed valve, no? it should remain closed if there is no power at all. would a simple on/off switch be enough? i mean give it power only when you want to drain.
I wanted to keep the tanks small and also since I have the sink on one side of the van and the shower on the other side it would have been difficult to run drain lines across the van and still have enough pitch for them to drain.
@@yourpcmd it's not set up where it needs to drain uphill so no. While some water remains in the pipe, there is nothing restricting it from filling the tank
@@WaybackRewind it’s not possible to fit it that way because the tank can’t be moved back far enough to have enough room for the pipes to make the bend, plus it would add another another uphill section to the pipe to get over the frame of the van. I don’t know if all that makes sense but to make a long story short it doesn’t fit that way.

The inlet to the gray water tank is supposed to be at the top of the tank. The main problem from the shown setup is that the movement of the van can cause the p-trap to be sucked dry when the water in the tank sloshes. One solution would be an additional vent between the p-trap and the tank, or use a HepvO Waterless Valve instead of a p-trap. Or, just deal with the odor - it should not be dangerous like real sewer gas.
What I do is I just leave it open while I’m driving and the last bit drains out. You can also pour some anti freeze down the drain. They make special RV drain anti freeze for this purpose
Those screws you used to screw brackets into frame didn't look like they had ANY thread for about 3/4 to 1" from the head of the screw--- how are they not pulling out of the holes??? It looked as if they they didn't stop when you drove them in-- (you even spun the heads after they were up against the brackets-- when they should have been tigth if threads were engaged)--- nothing to keep them from sliding back out to the threaded portion--- I would hope you replaced those screws with shorter "all thread" screws (off camera).... th-cam.com/video/Od5L_t8ygMs/w-d-xo.htmlsi=s1m5yCHtqs9FDinK&t=338
I don't understand why you have that fight club pic that pops up and goes away super fast. Please explain so i don't feel like i'm taking crazy pills lol
Dud your mechanical skills are not so smart. heads of bolts and that strapping will damage tank, whats point of using rust proof self drilling screw when you're drilling a metal Fram. ITS NOT THAT HARD TO USE A RIVNUT IN EXISTING HOLES OF VAN
really the wast water hooked to bottom of tank. last time i checked drain water will not push the water up in tank. dum a drain valve is supposed to be at bottom of tank not 2 inches up from bottom. DUD you punt tank in wrong. waste water is at top
My opinion this installation is poorly executed. 1, the tank is resting on the bolts head and will work through the plastic tank. 2, the solenoid valve is upside down, depending on the design the water pressure (water high) from the tank could open the plunger inside the valve. 3, the solenoid valve head is exposed to be damaged by branches or rocks.

No that’s not how this valve works. They sell like 5 different types for different applications. This one only uses power to move the valve.
If there is no power at all the switch stays wherever you left it.

Your drain entry is so low in the tank, doesn’t that mean you;l only get a small amount of water into the tank before it backs up into the drain?
Water stays in the bottom pipe but it fully drains into the tank without any resistance
This is not correct, the level in the tank will be exactly the same in the pipe. The pipe will be fully drained only if the tank is drained.

to be more specific water stays in the pipe when the level of the water in the tank is above that level....
