Feed and expansion tank

[Marcuse73]

Can anyone tell me what the correct distance is for the open vent termination to the water level in the F&E tank ????

Thanks

1"" or so above the overflow

don't think there is a set distance (could well be wrong)

as long as it ain't dipping in the water

No there is a set recommended max distance in the regs.
I got shot the question in a job interview believe it or not and its really got me going to find the distance - it's defo in mm and its something like 50mm - 100mm etc.

No there is a set recommended max distance in the regs.

check the regs then

Very funny - if I had a copy of the regs. I wouldn't be posting here would I !

I have the Regs in my Van, I'll have a 5 minute look

"Vent pipe shall terminate not less than twice the internal Diameter of the vent pipe above the top of the float operated valve or top of the overflow pipewhichever is the higher"

Edit: the pic shows the top of the float valve being the very top of the white plastic water spout. The top of the Overflow being the top of the overflow pipe (obviously)

and then you have the real world

Or as Kev said just above the overflow outlet, how far don't make an monkeys difference provided it's below the rim of the tank.
