Hi Thought I should update. Interestingly, having taken the readings more carefully, I find that when connecting to the earth cable (no inner insulation) I get a reading of 0.8volts. From the neutral I get 0.7volts and from the live cable I get 0.6 volts. In each case the other terminal of the...

Thanks. None the wiser as far as the technical stuff is concerned. But pleased to hear it is very common. So will seal up and put back where they came from Thanks for the advice

Thanks for your reply. Yes I do have the meter set to AC. Afraid I am too thick to do the maths as dont understand what the meter impedance means! I tried it on a light bayonet socket as suggested by running the meter from the two terminals in turn to a hot water pipe, but no reading. But of...

Hi I am confused! Whilst decorating, I found buried in the wall, two mains size cables (each with red, black and earth cables) that are simply terminated with insulation tape. It looks like they were part of a ring mains and were probably both connected to a mains socket. I tested it...

Thanks for all the helpful comments. Yes I was planning to have it in parallel to the existing switch. The idea is to have it set so the light goes on in evening when we are out. I can always override it if necessary with an isolation switch. And yes, it is a lot of light. We have a wall...

Hi I want to install a timer to control the lights in our front room in addition to the existing light switch. We have 12 x 50 watt (mains) down-lights so this is too much for any timer that simply fits in place of the existing wall switch, at least more than one I can find! So I thought I...

Thanks so much for feedback. So is it fair to say it works fine if it comes straight from the 22mm pipework. I can take it as a "mirror" from a radiator above but I might find I need to mess about with getting the two rads involved balanced. This was very helpful - better than the plumber! - thanks

Hi I thought I should open fresh thread for this question. I had a problem of 3 sepaarate leaks in radiator pipes bedded in a concrete floor. It started after a power flush and although everything has stayed dry for the last 3 or 4 weeks, I have lost confidence in that pipe work so want to...

Many thanks for the thums up.

I need to drain down the system and may have to do this a few times. I was wondering if I could save some time, and also money on inhibitor, if I closed all the radiator valves to reduce the amount of water that drains out. Is this Ok, or will it lead to air lock problems etc? One reason I...

Thanks for the help. I had to buy the entire kit just for the line, but it was nice and easy to fix.

Thanks for your input. I have since discovered the make is Siamp. I will look to get the part, thanks

Hi, would be really greatful for some help. On removing the push button for the wc, I must have snapped a tiny bit of plastic of the fitting that clips on to the back of the button. This is a white plastic "box" that is connected by pipe to the flushing valve. So now, the plastic fitting...

yes i think u r right. Thanks for your help

they cant afford to re pipe it unfortunately. Thats why I was hoping there might be a cheaper solution. They do have a room thermostat that seems to work ok. Its the babys room that is the last in the run, and obviously they want to close the door so he is not disturbed by the noises in the...

Thanks for all the posts. I haven't had the floorboards up myself (it's at my son's house) but the plumber said they were all in one line, and he took the top off all the TRV's as he said if one was closed that would stop the entire system. I think he checked it out carefully as, in the end he...

Hi I cant do any pics, as it is at my sons home, but the pipes come out of floor together at centre point under each rad, one then going to left rad valve, and the other to the right. The plumber seems a really genuine guy - it was my idea about maybe trying to push water faster, not his.

Not sure how do I do that? All valves are completely open. If I reduce the flow into any rad, surely that will just make the entire system less effective? Thats why I was wondering if I could speed up flow with stronger pump, or something Graham

Thanks, that is helpful. Sadly I am almost certain my son doesnt have any bypass pipework to the rads. The first is very hot and the last is barely warm. The temperature drop is huge. Is it possible to fit a stronger pump to speed the water rounds faster, or any other low cost ideas? Thanks...

My son has moved house (with his young family) and the central heating is very poor. He had a heating engineer round who was completely stumped but then realised it is what he calls a single pipe system. He has explained that the hot water goes from radiator to radiator in turn, so when it...
