Hello,
As you know, I've been working on my CH this week, which has involved draining and filling the CH.
When I went to check in the loft, I found a very slight drip coming from the header tank around the overflow outlet.
The nut is a pig to reach because the tank is small, the ball c*ck is in the way, and it's full of water! It seems finger tight to me. What is the best thing to do?
Should I drain the tank, remove the ball c*ck and try and get a spanner inside to tighten it further?
Should I be checking/replacing/adding a washer?
Should I use some plumber's mait/sealant around the outside?
Thanks in advance.
