any idea why there should be a sort of cracking sound from an expension vessel on an unvented cylinder? makes the noise as the hot taps are tuned on & off

If it's a pin hole or crack in the heat exchanger, the condensate will probably run more than normal when the heating is on

they can do that when the piston rings are worn, I have a chainsaw that does it, but it is about 16 years old!!

It's TNS, they've sawn the stubs off the bus bar where the neutrals were, then brought a neutral down from the neutral bar to feed in from below, someone had put a lot of thought into getting it wrong, in fact, thinking even further, the output should be at the bottom, so they wouldn't even work...

main bond size should be 10mm if neutral meter tail is 25mm, potentially 100amp demand, because we're not supposed to examine the main fuse to ascertain it's size, we have to assume that it's not 60amp therefore a 63amp isolator is not up to the job, RCCB's are definately not RCBO's, old LN5780...

would think either filling loop letting by or have known this on a potterton with a pin hole in the heat exchanger, condensate was running a lot on that though

seem to remember from talking to a property legal eagle, that if they don't have the electrics checked and something happens, they can get in trouble because they have not taken "all reasonable precautions", if there are things you can see by a visual inspection, ie, not dismantling, I would...

cheers for that, looked at a wiring job the other day, someone said, "we're on a very tight budget" I noticed the tins of Farrow & Ball or whatever it's called and asked "if you're on a tight budget, how come you're usin that stuff" continued with the job and charged them my normal price...

Cheers for that I was told similar by a spotty faced young kid in a decorators merchants, wasn't quite sure whether I should trust his advice but looks like he may have been right :lol:

What is the best paint to use on plaster in a stone cottage, been told it needs to be able to breathe to help prevent damp getting locked into the wall
