If your fairly competent you can change the isolation valve yourself instead of getting a plumber in. Seriously I’m a complete idiot and I have changed two now without any issues. Really simple stuff.ahh good news and bad news.
good - the leak isn't my work where i changed the fill valve thing
bad - the isolation valve has gone... gonna call a plumber haha
There was no ptfe tape on the joint so I didn't put any on when changing stuff - assuming thats right? (That probably sounds dumb but I don't trust the house builders to have done it properly in the first place haha)
Putting ptfe on would most likely fix the problem, at least 6 full wraps round the nut/thread joint plumbing wise (on any nut/thread joint it should have been done originally), .
Will do, I've never had one not taken especially when it doesn't say "fill line", I just get shitty remarks from the driver
Yea they say don't fill above the line, but since they take your money beforehand it doesn't leave them with the opportunity to add an extra charge onto the bill.
Shoot themself in the foot in that respect.
