Just had a look. The website indicates that I can use 1.5 mm for the whole length (which seems light). It also states that there will be quite a voltage drop over 30M. There isn't any function that allows a calculation of voltage drop with a larger gauge cable. Does voltage drop matter if it's...

I am planning on running armoured cable from an rcd protected fused spur out to a shower proof area housing pumps etc and weatherproof switches for a pond. The pumps do not draw much (max 3 amp) and the length is about 3M from CU to spur (internal) and 5M from spur to pump (external). This seems...

In answer to Lectrician there is quite a long distance to cover and I would need something like 6 double sockets, with spurs for other uses (just for convenience, not heavy loads) . It seems like it would use less cable and take less time to me. Also this would seem to give more flexibility of I...

Is there any reason why it couldn't be a 20amp ring?

Are you suggesting he's done something wrong?

As part of refurbishing a house we have had a complete re-wiring by a qualified electrician. He didn't do much in the garage, except re-use an old consumer unit and connect the few appliances in the garage to a couple of circuits on the CU. The garage consumer unit is supplied from the main...

very cryptic! The reason I want to know is because I need to decide whether to put in an oil fired heater / fire in my living room or LPG. If I put LPG in I would like to make use of the bottles I already have for my cooker rather than have to have 4 bottles in my back garden. The 2 existing...

Does anyone know approximately what sort of length of run provides acceptable pressure from LPG bottles to an appliance? Does it change if the same bottle is used for 2 appliances (IE cooker and fire)? Does it also change with any turns in the pipe? Thanks Ian

We have a builder fitting new windows into walls that are very thick stone. As part of the renovation work a new lining wall has been built inside with a standard cavity between the lining wall and the old stone wall. The window frames have been put in and placed in the cavity, which as I...

Hello, We are in the middle of a large project and have been told by the building inspector that we cannot leave ceiling joists exposed due to the need to protect from fire. We were planning on putting ceiling boards between the joists (as originally) due to the fact that it is a very low...

thanks for the prompt reply. I have 2 (BT phone) handsets registered to one base, but the further one doesn't work well even though it's only about 25m from the base (I assume this is due to very thick stone walls). We are refurbishing the ground floor which is currently derelict and I...

Does any one know how many handsets can be run from one master phone and over what distances? Is it possible to have two phones plugged in to phone sockets and run the rest cordless? tia

I was wondering this myself from something an earlier poster said. The whole system is very old so it wouldn't surprise me at all. I don't suppose there's an easy way to check :?:

wemyss, I very much appreciate the time spent trying to help me. When we bought the house 3 years ago the surveyor thought we were mad (and we probably were) as there were (and still are) lots of problems. Actually the plumbing is pretty good compared to the electrics! I might have to live...

Thanks for all the help so far. Chrisr - the water never gets that hot, but the point you make could still be true. wmyss - we do have two separate systems, my explanation is obviously not very good and I will try and explain in more detail. The primary system takes water directly...

The suggestion by the plumber / chrisr sound like a good idea and I will try it out. I am not sure what will happen. wemyss - the problems do sound very similar, but I probably haven't described my system very well. Until recently there was no vent in this part of the system. I put a vent...

That's exactly where we are now. We had already put a valve at the top of the vent so we turned off the water at a stop cock near the hot water tank, blew down the vent to clear any air, turned off the valve at the top of the vent and then turned the water back on. It's working after a fashion...

I knew when I posted the question that the most obvious answer (and the one that makes me look the dumbest) is the that the top of the vent is below the water level in the header tank. I have measured twice now, but the last time was a couple of weeks ago so I am again starting to doubt myself...

Could be, but I have described as best I can :roll: The two roofs are (apparantly) roughly the same height, The header tank sits approx 2 foot off the attic floor and the top is about another 3 foot. The vent pipe eventually went almost to the apex of the second loft. I measured the...

thanks for thinking :) If I can tell you any more that might help please let me know
