Perhaps the first question should have been, do I need to register/get permission for change of use?

We have a double garage that is quarter integral with the house. The idea is to convert the bit under the house to a utility room. There is a pillar in the middle of the garage which holds up the corner of the house so it is a matter of closing off two openings and cutting a door through from...

Yes, that reminds me that my first house had the meter under the stairs so the meter reader had to come in. There must be thousands like that. For some reason I had in mind that it would have to move as a matter of course. It's worth taking another look at the new doorway.

We have a half integral garage and want to convert the integral part into a utility/cloakroom so it properly becomes part of the house. The meter and fuse box are currently together at the back of the garage so I assume one basic requirement is that the meter is moved to the front. The fuse box...

Measuring pipe temperatures on my heating, I notice a convection flow effect driven by the HW cylinder during system idle periods, likely resulting in wastage. My thought is to put a non return valve between 3W port and cylinder. Is this suitable for CH...

Quite. The pipes are obviously "earthed" by some means and I'm not concerned about safety, only about interpreting the rules. So you appear to be saying that any bonding that exists between pipework ought to run back to earth in a more visible manner?

Hmmm. I was wondering whether I was missing something. Equipotentialed pipework can theoretically reach some voltage other than earth. On that basis, the supply and other pipes could be different.

On re-doing the bathroom a thought occurs about bonding. The main water supply pipe, bonded to the supply, runs up the bathroom wall to the tank. Taps and radiators are equipotentialed. Connection between the supply and the other pipes is then incidental. The supply pipe was previously...

I have two windows now unable to open due to failed Aubi gearboxes. How did you get the window open to get access to change it?

Yes, the cylinder is probably 40 years old. Adaptors and dimensions have changed in that time but least there was enough give to line up the 28mm entry pipe. I thought S/S looked attractive. Except the RM one I found didn't seem to have have an aperture for an immersion heater.

I was starting a project to add another radiator so had drained the system down. Except water was still coming through. Isolate the cylinder and sure enough the water was coming out of the heating coil. More than 5 litres/hour. The water level in the CH header tank is nominally about a foot...

Useful information from all, thanks. I did try to see what would happen with a multimeter and blowtorch. Nothing. I understand the essential difference now. When the fitter replaced the valve he did not touch the pilot. As best I can see through the window it looks as though the flame is...

My Baxi Solo had a very noisy solenoid and it was getting slow to turn on the main burner. The fan, igniter and pilot work and although the pilot is lit, it keeps sparking and won't reach that last step. The problem is intermittent which tends to suggest the fault is not with the electronics...

I don't know whether this is the best section to post this but here goes. The management committee of a small block of flats (of which I am a member) were not aware until recently that asbestos and fire surveys of the communal areas was an obligatory requirement. We have been going round...

Yes

Thank you for your input. It would help matters considerably if people replying actually answered an OP's questions rather than spending time questioning their parentage and trying to offer advice.

No, we were too occupied in improving the basic boiler operation to imagine a gate was also faulty. Something for next weekend. I will let you know the result. Apart from that, there doesn't seem to be any need to continue this thread.

Yes, that was one of the questions in my first message. I know it should not be possible but is it totally, absolutely impossible? You agree that my boiler plot shows the valve is not stuck in one position? Though by "rad side" above I intended to mean the rad circuit in general (which might...

Thank you, my son in law has continued to work on it alone today. We have reached the conclusion that a gate valve on the rad side of the 3pv could be stuck shut despite the shaft appearing to turn properly. (Not in circuit when we flushed) It was too late this afternoon to strip down again to...
