Hi

Is there not a drain plug underneath (outside) the van?

[Beastman]

Hi there ...not that I can see

[dumbo]

hi.....so why cant you... just use your tap..... and empty it that way.... park over a drain and there you go cheers simon

I used to siphon it out of my Autohomes Kamper. Found it was best to park up on kerb so water flowed to sliding door side.
Under the rear seat is a bung with a 3inch ish sized hole. I could just about get my hand in there to direct the end of the tube into the corner to get pretty much all the water out

Hiya tried to do that but the pump doesn't work due to the wire terminals have broke

Does anyone know how you would connect a micro switch tap instead and which would be the best one?

either way, flush it to rid it of tooth cleaner and dont use that again

Should have used this stuff first,

Then use Aquatabs to keep the water drinkable once the tank is re-filled.

Are you sure there is no external drain hose near the rear of the vehicle. Usually on the opposite side to the sink / grey water outlet pipe.

as ^^^ says, any caravan type place will stock it just goog puriclean

Do you know how to siphon? Long bit of pipe/hose that will go down filler into bottom of tank. Suck 'till water comes through, clamp thumb over end of pipe smartish, lower pipe to BELOW level of bottom of tank. Let go of the end and water should flow out until tank empty.
Useful for other fluids too.

Thanks I've found the outlet/draining pipe is there a switch to operate emptying it?

[Plasticman]

keep looking, there will be a valve someplace

A tap usually has two wires coming out of them. One is the live to the battery/fuseboard, the other is the live to the water pump (if you have one).
