Always had a downstairs bathroom but recently also had an upstairs bathroom fitted and Worcester boiler moved.
Having some nagging issues such as pressure dropping on the boiler, no apparent leaks. Also for some reason if I turn the heating on after coming back from work and try and use the upstairs mixer tap shower, the radiators won't come on until I've finished in the shower. Also had a new radiator fitted in the new bathroom. I've also noticed that if I use the hot water tap from the new bathroom, then the pilot light will switch off until the hot water tap is turned off.
Since the install we can hear random knocks from various pipe works leading to random radiators after we've turned the heating, ie before going to bed.
Had a plumber do the plumbing for the bathroom and new radiator and a gas safe person move the boiler.
Help please, is the problem with the boiler or new plumbing?
It only took 3 hours to move the boiler, I found he had run the electrical wire around the hot water pipes, when I asked an electrician to re route the wire, he noticed the spur box had singed and was black, he didn't tighten the wires correctly.
There is a slight random noise coming from the boiler.
