I am about to change over an external security light and wanted to be 100% certain the power was off before meddling around. An electric shock whilst up a ladder is not worth thinking about. Anyway, I switched off the circuit breaker and double checked with the NCV setting on my multimeter. Very...

Hi I have noticed occasional drain smells in the bathroom, that seems to come from the bath plug hole. As there is a shower (and sink), the bath is rarely used, and just by running a little water in the bath, the smells goes away. The bath trap is not very deep so I could change it over for one...

Hi I have moved to a new house that has a new dual flush Roca toilet. Afer flushing, some water continues to run through from cistern to wc bowl. I realise this is a "flapper" problem and have taken a look but cant see any obvious damage to the large plastic washer. Reading on forums, it...

Hi I had a problem with the ball valve in cold water tank in loft. I replaced it but now get a mild case of water hammer coming from loft area. I am wondering if the old valve was an equilibrium valve, which would explain it, as I just fitted a straight forward cheap one. I still have the...

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...

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...

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...

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...

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...

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...

Hi, My first posting although I have followed this excellent forum for a long time. I have what I think is called an "open" system (Not a combi boiler). The boiler is old but seems to work fine. The radiators are on, but the only way I can get the radiator in the bathroom on (which is on...
