I don't get the drama about a flat tank being a problem. I just park the van 'the right way' so the outlet is at the lowest point.

You can’t necessarily do that though can you especially in a one way street etc if you live in a relatively flat area like Lincolnshire you would prob get away with it but you certainly can’t ware we live , I don’t know a single cleaner that has a flat tank as they won’t work here .

My area has some flat areas and some pretty hilly bits. My outlet is on the nearside front so generally works with the camber of the road.

But what happens if you are facing up a reasonably steep  hill ? I found it was drawing air as the water went to the back of the tank once you get to half a tank full  and the outlet was above the water level

Very occasionally you have to be mindful which way round you park the van, making sure the water is angled to the outlet, but for me, having a 750l tank, that’s rarely an issue. I can make 750l of pure last almost all week! So on the day when it’s only got say 200 litters left, as it runs low, I just have to be a bit more thoughtful on how I park. It’s very rarely an issue.

You also have the option to carry 2 or three 25l drums of water to top up the tank if necessary.

I will probably be going to smaller tank when I get the e custom, so I’ve been toying with the idea of having a 100lotre small upright tank in the van as a backup. I’d use this if and when the water in the main tank gets very low. It’d be permanently plumbed into the same hose line to the pump, but with its own isolation tap. So if only turn it on when needed.

There are so many options, it’s pretty easy to navigate round these small hurdles.

I’m used to parking where I can pull the hose as I walk. My work is compact and if I was in a street where it might be downhill at the start of the street and uphill at the end of the street I would find it a PITA having to turn the van to face the opposite direction.

You just need to fit a non-return valve on the tank outlet. Cost about a fiver and pretty much eliminates air ingress! I've been using one for years. 👍

That doesn’t work when the vans parked up hill and the water level is below the water outlet , I found this to be the main issues with a flat tank.

Errrrrr.... Obviously! But it does prevent air ingress from the water movement when the level drops to a low point.

But quite often you end up with half a tank of water you can’t use if parked on a hill, that was the main issue I had then you got air in the system and it was a pita when you did have water above the outlet again ,.

This is what a non-return valve will help with. You can't draw water when the level is below the outlet (obviously) but the NRV ensures that  air is not sucked into the outlet pipe- like it is without one.

How are these wired into a battery? I have one of those electronic devices that charges the battery . I have one of those vans that stop and start when pressing clutch .

You need a separate leisure battery in the cargo area
