Image 2 shows the earthing to the stopcock. the earth goes across the house and is then earthed into the C U (the earth cable is actually behind the white cable in Images 1, 3, &4). Image 1 shows the other earth running from the main gas supply to the CU. The other black pipe next to the gas...

Earthing of Stopcock and Consumer Unit

Thanks. The rising main is earthed and so presumably, if there are no plastic pipes I could assume that effectively all the other copper pipes and metal appliances are earthed and that I only need worry if there are plastic pipes which put appliances beyond the earth ? but even then, I can't...

Thanks everybody. It's now sorted. I just connected one cable to the old fixing with a bulb and it worked so obviously that was the ring and the other cable was the switch.

It is 5 amp lighting circuit with two 3 core cables hanging from the ceiling. The old 1965 light fitting had 3 terminals, all identical, none marked. The wiring was done so that the fitting could be utilised for the switch wire. The replacement light has a connector with live, neutral and earth...

i am replacing a light fitting but the switch return has not been marked and I cannot get fingers up through plasterboard to tell which cable goes where. Will it make any difference if they are reversed on the fitting ? (it is metal but will be earthed ).r

I've just had a new boiler and the electrician said that my Consumer Unit is out of date as 17th Regulations mean a new one will have RCD's. I raised the subject because I wanted to know whether my bath (which is all concealed plumbing) might be earthed. Electrician said A new CU would provide...

My old floor-standing Potterton Kingfisher II has been replaced by a wall-mounted condensing boiler with it's own flue. I now have a 'redundant' flue. It was a flexible tube which is inside a brick chimney passing up through the roof. As the photo shows, the short length which connected it to...

Thanks I will set the tank at 65. as the thermostat is about 1/3 up, I assume the water at the top where it is drawn off will actually be slightly hotter. I will set the boiler at 70. As for the TVR's, the heating engineer just installed them when re-piping the system. I think his idea was...

I have a vaillant Ecotec 18 pumped open vent Y Plan with room stat and cylinder stat. The room Stat is in the lounge. Is this ideal or should it be in the hall ? (I hardly ever use the lounge fire). All rads have thermostatic valves. Should I replace the lounge valves with non-thermostat...

I've had exactly the same problem although I had to swap the toilet and basin so that the towel rauil would be next to the basin. It was actually straightforward. the floor is boarded and the soil pipe exited straight through the wall. So we just drilled a new hole through the wall and blocked...

When your CH packs up you call a CH Enginer. When you want legal advice you call a lawyer. You will never recover from the farmer because you would have to prove that it is your pipe in the first place and that he has been negligent in cutting it. As a tenant he can hardly be negligent in...

Thanks for all the replies. My current boiler is 50,000 btu which is 14.64 kw. My own calculation makes me think that I will be OK with an 18ri. I have phoned W Bosch Technical and they confirm that if old boiler is IK then I can do a like for like swap so I'm going for a 18Ri 61,416 btu (and a...

Its a Potterton Kingfisher II CF 50 installed 1990. Heat output 40,000 - 50,000 BTU. It works well and is normally set at '2' 9it goes up to 4). I just want to update evrything due to house alterations.

I'v had 3 quotes for a replacement boiler and replacing pipework on one-pipe system conventional vented by a 2 pipe system.. The old rads (1965) seem OK & will stay). I've been quoted on a W Bosch 18Ri by B Gas, another on a 24i System and now the 3rd plumber says system boiler is too risky on...
