I think I should have checked the CU before posting. I can now see the circuit is actually protected by a 5amp breaker at the CU anyway so I guess it will be OK as it is. I thought that all lighting circiuts would be 15amp and have never sen a 5amp lighting circuit before so I didn't check...

In my conservatory there are presently some spot lights wired up with 1.5mm twin and earth cable and instead I want to fit 2 chandeliers which each take five 40w bulbs. It would be ridiculous running these 1.5mm cables down the chains, so I purchased some 3amp 3 core transparent lighting cable...

I couldn't see FAQ at the TOP of the page I was on. It's not that easy to see but I can see it now.

Yes I know. I have a heating engineer coming round to get it going. I have a million and one jobs I drained the system as I said earlier, but some rads are still full. I closed the valves either side of the pump so hardly any water came out. I will check the impeller again though. I...

Yes I did that last night and the impeller is free with no residue. I did consider a flush but it won't fully drain so I think there is an air lock somewhere or the fact that I freed up the system by unblocking it, it could have caused another blockage. So I don't think I will be able to flush...

Yes it did seem rather odd but I managed to sort that part out. The property is a bungalow btw. The roofspace was a real mess of pipes and insulation. As the house was vacant for 2 years it would seem that someone turned off a second gate valve on the mains feed for some reason, which was...

Sorry I should have said ball cock on the feed tank. I disconnected a joint further down the pipe and there's hardly any water comming out and obviously it should be high pressure. The pipe divides into the cold water system as it comes into the house and there's a stop cock in near the...

I cut the 22mm feed pipe in two places, cleared the hard deposits at the T and connected it all back up. Yes I am sure there are blockages in the system still but it was working OK until I drained it down the first time to fit the new rad. Maybe it released a lot more deposits and has gummed...

You were right. The feed from the tank was totally blocked at the T. I cleared it and bled the system. But the nightmare continues. The mains water pipe to the stopcock is also blocked. It's an old iron pipe and someone has fitted copper sections at both ends. Anyway, now the boiler fires...

Thanks, but where will I find that? Thanks but where ill I find that?

I have poked a long wire down it but the blockage seems to be quite a long way down. I'll try the magnet thing tomorrow. Maybe the mouse went deep, deep down? If I find one I'll give it a decent burial.

Thanks again. I'll try that in he morning. I'll let you know how it goes.

Thanks for your response. Do you mean the pipe which from the header tank and goes into the boiler? Is this something I could do myself? Why does the pump keep running? If I force water into the system could that release the blockage?

My heating system always seemed to be working OK until I replaced a radiator. I thought I had drained the system, but when I went into the loft to refill the header tank I found it was still full. I tried to bleed the rads, some bled some didn't. I tried to bleed the pump to see if I could...

I did say that I wasn't trying to be clever and I think the question was valid. I have had a few people on other electrical sites who have been unable to answer that question with any certainty. The last comment from EFL Impudence resolved it for me.

Understood. Thanks

OK Thanks

I know that I can put two appliances on one spur but I wasn't sure about a fridge freezer and a second freezer. I now know that is OK. I was just asking why you can't have a tumble dryer and a washing machine on a spur if they draw less amps than the cable and factory fitted plugs can handle...

My other question was why not? They appear to draw less than the cable and the 13a fuse can take.
