that to me looks like an overflow from the tank in your attic
dont touch it
if your ballcork gets stuck and the tank treaten to overfill, which would ruin the house, this pipe takes away the water from home

It is 1 1/2 abs pipe. At the top of this pipe an air admittance valve is fitted. This allows air into the sewer system and maintains apressure equilibrium. It does not allow air out.

Normally fitted where an open vent pipe is not permitted.

that is the very one i was speaking of
it is going right up, it is painted grey half the way up
now i bet inside that wall is the water tank that supply the home
another thing it can be
it would be there with top open, to release any gasses from pipes as gas can build up, so here is where it would release outside,

Thanks for that.

There is like a small vent bit on the top of it allright.The pipe goes half way up the wall and then just stops.

I was confused as to what the hell it was for.

The water tank in is the attic in a different part of the house.

The other side of that wall and pipe is bathroom and ensuite.

The pipe just stops half way up the wall,it has a little vent thing on the top of it,so I rekon that Mickey is right in the 1st place with regards venting thingy.


At least I know what it is now.

Thanks.
