Yes, thats the bit in our boiler the pipe goes out of the wall, my huisband turns that to release the water out, we are stuck s to why it keeps coming out.
kim reed said:As my first questions stated, My boiler was losing pressure going from 2 - to 0 in hours, there was always water coming out of the pipe out of the wall ( the pipe comes in and goes into a round biggish grey like barrel thing and then up into the expansion vessel -)
in threads here it said for someone else to press the valve on the exp vessel and see if water comes out if it does it is broke. I did this but it was the AAV by mistake as not knowing I saw this with a valve and pressed it in, then water kept coming out, no car valve fits it so this became a problem and I have now ordered a new one but means our boiler has to be totally off now so no hw or ch.
We then found the ex vessel and pressed the valve and air came out my husband pumped some air in with a bike pump and no difference. He put the boiler back on and AAV valve still leaking water and the pipe out of the wall leading from the boiler is leaking water ALSO. So so far still off !!
