Thanks. I have just run the mixer tap in the bathroom and yes the overflow starts dripping. I'll take a look at the loft tank tomorrow and see what's happening. In terms of fitting check valves, is it an urgent problem would you say? I'll need to figure out how brave I am to attempt this...

Hi Armo - what would be the cause of that? Is it something that I can easily check? Do you mean that water is being fed back into the cold water loft tank which in turn is causing an overflow?

That is something I will need to check tomorrow. The F&E tank had it's own overflow pipe which has now been removed when the new boiler was installed. I can't imagine there's anything else that could feed into that pipe but I'll get up there tomorrow and double-check. Thanks again.

Hi Belboz Yes - and it's a good couple of inches below the overflow so it's definitely not the water in that tank causing the dripping. And it seems to only happen when we've used lots of hot water - does this sound likely? Thanks

Hi - the overflow pipe that comes from the cold water tank in the loft is dripping onto the path outside. I have noticed that it drips after we've used hot water (showers and baths). It's not a massive problem, but the overflow pipe is right above the back door so it's annoying. At worst...

Hi - I have an Autotrol Osmonics 255 water softener. The brine tank is full of water - the regeneration cycle seems to work fine, but about 20 minutes from the end of the cycle, the Refill starts and it doesn't stop until the tank fills right up. I think the unit has a problem in shutting...

Thanks again. How would I use my multimeter to first check that the faceplate isn't live? Thanks.

Thanks - so I do an AC test on the plate whilst the wander lead is connected to the MET? If the plate is live, wouldn't I expect a shock even if I'm not holding the wander lead (if I touch the plate with my hand). I use most of the switches/sockets regularly as so far so good, but hence why...

Sorry I meant to ask - presumably it's OK to leave the power on if I'm only going to the faceplate - it won't affect the validity of my test?

Perfect - thank you. Yes, I was going to use the lead from the point next to the consumer unit where the earth cables are - if that's called the MET? My only concern is that some of the earths weren't connected in one of the rooms in the house when I did a continuity test last year. That...

Hi - last year I replaced all light switches and sockets in my house with metal ones. I made sure that all the earth cables were connected etc. However, I didn't perform continuity checks on the earth wires... In total, there are probably about 60 sockets/switches. If I have to unscrew...

And in addition to my question above, before I go the expense of replacing the downlights: - All of the downlights are the 12v low voltage type. I'm guessing not, but does this lower the 1660w calculation that I've made? - Would I need to replace the 12v transformers for the downlights...

Hmmm, maybe I should look at the LED option. What would the safe load on a 6amp circuit be? 6 * 230v * 66% = 910w?

OK, thanks. The RCBO was installed/replaced by a Part P qualified electrician last year. This was when we had some work done to our kitchen and two lights installed outside the back door. I don't know exactly what work he did but I'm surprised that he wouldn't have sized up the circuit?

That's not all the lights - that's just some of the downstairs and outdoor and porch lights (yes, lots of outdoor lights). We never have all of those lights on at the same time, but still now that I know there's a potential fire hazard, I can't really ignore it. Does that B6 one tell me...

Thanks for the reply. Does the RCBO in the picture (far left) indicate that it is a 6amp circuit? Thanks

Hi - I want to add another strip light my garage, so I've totalled up the current circuit wattage and I'm worried... I have the following wattage on one circuit breaker: 20 x 50w spots = 1000w 11 x 60w bulbs = 660w Total = 1660w I think it's a 6amp circuit - or at least I know that...

My Karcher pipe cleaning attachment arrived yesterday - tried it this morning and the blockage went - total 5 minutes work!! Thanks for all the replies... :D
