Looking for a bit of advice, we currently have a Smev sink in our van the outlet from this drains via some convoluted waste hose straight through the floor, see picture of outlet, we then place a Fiamma grey water roller tank under this to catch the water that comes out.
As you can imagine this is an absolute pain in the *** most of the time, if the ground isn't level the tank either can't fit under the van or the pipe is too far from the tank, I have lost count of the amount of times I've forgotten about it and tried to drive over it and emptying is a nightmare especially in aires etc. it can look suspiciously like we are emptying our toilet. Recently we have taken to replacing the tank with a collapsible bucket and emptying as we go but again its not ideal.
So I've decided to fit a proper grey water tank and have got a tank that is shaped to fit nicely over the rear wheel arch. See picture with tank and fittings supplied. My big concern now is to actually fit it correctly to avoid smells coming back into the van.
I was going to run the waste hose I currently have to the top of the tank clamping it on the way to form a u bend. I presume the tank needs some form of vent from the top/overflow pipe. Would it be ok to bring this out of the top of the tank and then down through the floor. Would this provide enough venting?
Finally there is a drain point on the bottom of the tank, my plan would be to run this through a 12v motorised valve with a switch mounted in the cab so that when at a drive over drain it would just be a case of flicking a switch when positioned correctly. I have ordered a 1/2" motorised valve but I'm beginning to think this might be too narrow. Is it likely to get clogged by sediment in the tank or does this tend to get broken down by driving?
Any advice would be greatly appreciated.
