Hi, I've had a new kitchen installed and bizarrely the fitters don't do the plumbing so I decided I'd do that part myself. I'm fine with the taps but I have a query about the sink waste... It is a stainless steel Franke sink plus their special waste system. The instructions concentrate more...

Ok. I guess there would be a voltage at which they would fail to work but that would probably need quite a significant drop and not one that I'll encounter. If you're interested, this was the main thread I read about it, although mine are white only, not RGB. It sounded like they knew what...

Monkeh, so should I be looking at a fatter cable? I actually did a bit more research on these LED strips and also came across people saying that the higher power ones didn't seem to draw as much current as they were rated for. There were then all sorts of theories about voltage drops across the...

Brilliant thanks, that Maplin XS70M 6 amp stuff looks like just the sort of stuff I imagined. I could only think of speaker cable and bell wire but they aren't usually rated for current. The Maplin one has a sensible "Twin Power Cable" name :) Re. your comments on Bell Wire, I guess it...

Hi, I have a newly re-wired kitchen (by an electrician, all signed-off and properly certified) and they have left me a safely terminated 230v cable coming out of the wall that is ultimately connected to a wall switch so that I can add LED under & over cabinet lights once the new kitchen units...

It is definitely before the valves, my concern is just that it is pypassing to the DHW circuit rather than the CH circuit. I understand what it is for and that it should (normally) bypass on the CH circuit, I just need to know if there are any (rare?) reasons that the plumber may try and claim...

Thanks for the feedback so far. I can only assume he thought the ABPV would dump the excess heat into the cylinder. I've adjusted it today (following advice on another forum thread, I shut down all TRVs and I have two rads without TRVs. I turned the ABPV to full at 0.5bar and it did NOT pass any...

Hi, I've just had my central heating boiler relocated and a new unvented cylinder professionally installed. I was surprised at the hot water temperature coming out of the taps was so hot even thought the cylinder stat is set at 50C so I started looking at the pipework. When the programmer was...

Thanks, that's good to know. The upstairs landing does have a small rad which didn't have a TRV before and presumably will continue to not have one. You are also correct that every part of the upstairs landing would get some rising heat from the wood burner too since it is actually an open...

My house is undergoing renovations and as part of that the hot water cylinder is being moved from bathroom to utility room and changed to a mains pressure one. (FYI, work being done by a certified installer). Anyway, the plumber is also changing all the old radiators for new more efficient...

Thanks, Tony. I guess my mental measurement isn't very good!. I was at work and knew the house was 12m long and that the pipe was going to the back end. I thought the distance from the roadside was about the same again, hence the 25m estimate. Of course, when I got home and we measured the...

Will do, I didn't realise they needed a special certificate! They were recommended by the builder who's doing the main renovation works and we've seen a similar system that they installed in another house. They're from a reasonable sized plumbing firm (i.e. not just a one man outfit) and they...

Thanks, I like that idea. Will see if I can get plumbers to do that. When you say "flex", would 22mm push-fit do the job or is that also restrictive? We ended up laying 50m of 32mm MDPE from the road yesterday but the house is 53m away so the last 3m dropped down to 25mm. Just need to get the...

Hmm, so I may not need a larger meter then. That would be good if I don't. The plumbers had suggested they would leave a couple of inches of 15mm on each side and reinstall it off the new 22mm inlet (off 25mm MDPE). We're installing new 25mm MDPE from the road tomorrow so that we get rid of...

Thanks. I guess that means if the cylinder specifies it needs a 22mm feed from the mains then I'll need to get the water meter swapped for one with a larger/fatter bore. Anyone know if water companies deal with that kind of enquiry regularly or am I likely to struggle to get across my requirements?

Hi, I'm having a new feed into my house that will have 22mm pipework to feed a new unvented cylinder. The plumber suggested that having a very short piece of 15mm pipework just inside the house (around the existing water meter, which the water company has said he can re-fit) should not be an...

Hi, I am hoping to build a small workshop inside an old barn. The barn floor is currently soil as it was an old potato store. I would like an insulated concrete floor. I've searched the forums for general floor construction advice but can't seem to find anything specifc. I think I need...

Hi, I have a 1960's agritultural barn that came with my house. It has a solid concrete gutter along each side (quite wide and strong - it safely supports my weight). Anyway, each section is about 10 foot long and several of the joints between them are now leaking. In the past they appear to...

Hi, I've just had underground soil pipes replaced beneath my driveway. They are modern PVC type material. Unfortunately near where they originate at the back of the house the builder could not lay them deep enough due to eventual shallow depth of septic tank (he said he wouldn't have had...

I am considering moving house shortly. An electrical report supplied by the vendor (from 2009) has a note from the electrician saying something about the "Earth Loop Impedance" being too high (I think it said 0.58ohms). There are also copies of follow-up letters from the local distribution...
