Hi John, the house was rewired about 25 years ago. Part of the job was putting in a consumer unit in place of the original fusebox, so presumably the electrician replaced the old transformer.

Solved - John and Skenk were right, there is a transformer (white box) next to the consumer unit in the garage. Thanks to everyone for items of electrical history.

Hi John, the bell works fine, I took the actual bell part off it because it was deafening, but it still makes a sufficiently loud rattling to serve its purpose. I measured the current by getting someone to push the switch while I held a mutlimeter cross the inputs to the bell. Tried DC first and...

This is curiosity rather than a practical problem. This doorbell and push switch have been part of the house since I moved in thirty years ago, and probably date to the time the house was built (1952). The push switch is inside the porch, the white wire leading to a second (modern plastic) push...

There's definitely no earth; I fitted a new bathroom light last year and there were only live and neutral wires, including in the roof space above the bathroom.

Thanks ban-all-sheds and EFLImpudence

Thanks Diyisfun

The cord switch in my bathroom is showing signs it is about to depart for Valhalla. I had a look on the B and Q website and it gives a choice between a 1-way and a 2-way switch. Can anyone tell me which of these I need? Here is a pic of the old one: Thanks, Chris

Those who contributed to this thread might be interested to know its resolution. The second plumber/installer has just left. It took him ten seconds to determine that the first plumber, as Tony and others diagnosed, had in fact installed the pump the wrong way. All he did today was feel the...

I think MS know exactly what they are doing. Windows 10 now runs as a service rather than an operating system, and there is fear that at some point MS will start charging an annual fee rather than sell perpetual licences as now. This won't affect current builds but if it's done it will affect...

This is often reported on in the computer press. Many commercial applications are going to be stuck on XP for years, and Microsoft is quietly supporting these systems, which include systems running on vital medical equipment. There is a registry hack you can do to fool Microsoft into thinking...

Good suggestion, which I should have thought of :cool:. I will do some archaeology on previous threads.

:D This might not be the best time to tell you my last job title was Microsoft Systems Developer :LOL:

Good one! But no flow chart or logic diagram I have ever seen is as incomprehensible as plumbing systems. When I look in the airing cupboard it's like copper spaghetti, pipes going this way and that way and who knows where. How do I know there is not some curious circumstance by which a blockage...

On the basis of what you have said I will not go back to this firm until I have got another plumber to come and adjudicate. If this second plumber confirms the pump has been put in back to front then I will cast the current plumbing firm into the outer darkness. A shame as they have done all my...

I have an update on the story :cool:. For those new to the saga, a plumber fitted a new pump to my system in August and (probably) since then, hot water has been circulating through the feed and expansion tank at a fast rate (one pint a minute). Magnet tests show iron deposits in some of the...

I don't think they could possibly charge me for this. I don't think they could possibly charge me. Which might be problematical as they will hardly be in a hurry to do a job that will earn them nothing. I'll find out tomorrow :cool:

Thanks very much for this Tony! It was quite a young person who did the job. I'm glad I delayed phoning now. I'll call the plumber tomorrow...I won't mention the deposits in the pipes until they've corrected their installation of the pump.

It's definitely the other round! With the boiler audibly going, I can keep my hand comfortably on the right hand pipe but the left hand pipe is scorching hot. What does this mean? I like the light switch too, though it probably should have been replaced at the last rewire.

Hi Tony, the boiler is an Ideal Classic FF250, top and bottom pictured below. Is it possible to tell me from these pics which pipe should be hotter than which other pipe?
