There are two black painted pipes about 1 inch diameter that comes through the wall - can’t tell if they are copper or plastic though - has a metal feel to them but heavily painted black. Could you enlighten me where does condensation water come from? It’s a lot of water I’ve collected today...

Pressure gauge does not move when boiler is on. I don’t think it’s normal for condensation drip to accumulate to 250ml per hour?

It drips when CH or HW is on, and this corresponds to when water pressure loss happens. Also I’ve noticed water pressure holds OK when CH and HW is off

it is most likely the condensation pipe. drips about 250ml per hr. does this make diagnosis easier?

Hi all I hope someone can help me debug this mysterious issue. 5 year old Worcester Greenstar 32CDi boiler started losing pressure fast. Refilled to 1.5 bar last night, and by this morning it was down to 0 again. This happened multiple times. Last week it was serviced by a gas engineer (the...

I did use PTFE :) - I had jointing compound too but somehow thought a few rounds of PTFE on the olive is safer than compound :)

Thank you Dan - brilliant tip - I knew I was missing something simple...!! What happened was - whoever fitted the old stopcock fitted it the wrong way, so when I replaced it with the new stopcock I put it in the same direction - and I was trying to fix it on my own, so didn't test which...

I omitted to say - after I've done my repair - CW in bathroom worked fine for a couple of days - then one day I turn on CW in bathroom faucet and a loud 'thud' sound then no CW at all... I also looked at stop cock - went as far as replacing it with a brand new one - still no luck :(

I fixed some leaking pipes from floor board nails - but replacing the damaged sections with new pipes and used compression fittings to join them together. Leakage fixed - but I now have a REALLY BAD AIRLOCK... - No CW in ground floor bathroom faucet or toilet cistern - HW good in ground floor...
