Grey water emptying

[Huwmari]

Simple enough one would have thought and indeed it was on our previous van - open the tap over the grid and hey presto. However, in our present van we have a problem: the grey tank won't start emptying until it's full. Sounds crazy I know but has anyone else had the same problem or have any idea what we can do about it? Help please.

Question.. Once it is full, does it empty completely ?

 

[Popeye]

Do you know why it won't empty until it's full or are you asking if that is the case?

Yes it does.

Hi, I'm asking why it won't empty unless it's full. Nothing will come out until the relevant warning light shows on the control panel telling us the grey tank is full.

Does it use a pump to assist emptying ? If so maybe's a micro switch type thingy doesn't activate until level is reached..........

 

[Jaws]

Sounds like it has some weird valve system that will not open until the light comes on. Bit of a daft idea if that is the case !
Think I would investigate and fit a wee switch to bypass the system

Sounds just like a toilet siphon.

Very odd.

Actually it is not strictly a "grey water emptying" thread but rather, a "grey water TANK emptying thread" ...

All a matter of finding out why this tank has to be really full before it will start to empty.

Just a way of making sure you are overweight when the plod stop you and you cannot dump the evidence over his feet.

Very strange...... Most grey tanks simply have an outlet at the bottom to dump it all over your feet when you turn the valve handle.

My tank is home made and just has a removeable cork in the bottom.When cork is removed the tank empties quickly and completely

Just fill the tank via the tap, then empty grey tank and re-fill the fresh water at the same time.....Simples!
Cheers, Dave

Hi Dave, we have been doing this but it wastes a lot of water and sometimes we want to empty the grey tank before it gets full up.

sounds bonkers, have to think something is wrong or over engineered, which still equates to wrong

we use our grey waste to flush out black tank pipes, would be a nuisance for us

must be a way round it, hopefully

Have you had a look on the IH owners forum? I found it just now. There seem to be a number of problems with the control panel. Hope you can sort it.

Different to ours, it was just a thought, thanks.

 

[Huwmari]

Thanks to everyone for their replies. We belong to the IH members club so have also put a post on their forum. No solution so far but live in hope.

Agreed it is bonkers, but maybe you just have to put up with it . and wait till it's full.
Cheers, Dave
