Yes it's a multimeter with a non contact voltage tester setting. I am curious what it is picking up. Even if the meters faulty, it's obviously is finding something and as mentioned earlier, I can only guess that's a phantom voltage induced from a parallel cable running alongside it, up to the...

Thanks. This is also very interesting https://www.nema.org/Technical/Documents/Bull_88_reaffirmed_12_15_11.pdf I think it must be a phantom voltage I am seeing. The cable concerned runs all the way to the loft of our two storey house, so I imagine it must run alongside a number of other cables...

Say - Yes I will. Just to be sure, I intend to access the light from a ladder, and test the cable with my multimeter, from live to neutral, live to earth (assuming it has earth I havent looked yet), and from neutral to earth. I will then check the multimeter on another known live connection. I...

Thanks for the responses. Yes I have an Amprobe multimeter (http://www.amprobe.com/amprobe/usen/digital-multimeters/am-500-digital-multimeter-series/amp-am-510.htm?pid=74033) which has a non contact voltage tester. I was planning on cutting the wire in my loft to fit a junctin box so I can...

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 Sorry for delay - thanks for the help. Greatly appreciated Graham

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 It would be bad manners not to report back and say thanks. I fitted a "type 2" valve as recommended from screwfix two days ago and so far, so good. Clearly I paid too much credit to the plumbers merchant who sold me the part 1 valve previously! Thanks for all your help

Thanks John - good advice.

With the information you guys kindly shared, I have been googling and now understand the difference, at least in appearance of Part 1 and part 2 valves. My old one was definitely part 2 valve, as it had the white plastic on top and also the arm had a factory-made right angle. The...

Thanks very much. It appears the local plumber is perhaps not as reputable as I thought, as I told them exactly what i need it for. And the one on the link above is only £8.59 so I can certainly stretch to that. Thanks so much, really appreciate the help Graham

try again //www.diynot.com/network/Graham22/albums/ There are reputable merchants - dont think they would sell me a banned valve

It looks like this (if I have uploaded pic correctly)

Thanks for the reply Yes the original was a brass valve with long arm, etc. The new one could well be rubbish, I dont know. I bought it from a reputable plumbers merchant. It doesnt have the plastic piece to point water down (the old one did), but the water comes out at right angles to the...

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...

Thanks for the reassurance. Finding the other end would be very difficult and inolves picking up newly laid wooden flooring etc. Many thanks for the help

Good point I have connected to a known earth but I do get similar results of 0.6V, 0.4v and 0.3v . Graham
