When you said switch, I pressumed that you meant another switch which was hidden. What you have said makes sense. I think I'll cancel the engineer and make do with matches. Thanks once again

I have a Corgi chap coming tomorrow. However I have experienced unecessary work being done in the past and want to make sure this doesn't happen again. So am I right in assuming from your comment that in the hob there is a switch that sends power to spark generator, to then spark on hob and...

Hob is sparking continuously. I have switched off poer supply. I think it will be either electrodes or spark generator which is faulty. Anyone have any idea of how I change these on a built in unit???

Never used them, however the price of the boiler seems ok, when I have paid for flue and bits and pieces it has come to that, you may want to check out prices elsewhere. You will also need a filling loop. It may be worthwhile ordering a couple of drain off taps i your current system hasn't got...

You don't want electrical appliances in a toilet at all. Its breaking all the electrical regs

It is preferable for it to be as near as the end of the socket as possible.

To accurately measure the length of pipe stub required do the following:- 1) Stick a tape measure up the inside of the valve opening where the tail pipe will fit. Just take a measurement. 2) Then hold the valve in front of the existing pipe and align it horizontally, at the base of the valve...

When pump isworking, if you place a towel under pump. When the pump is working i.e. power is sent to it if you undo the screw and place a screw driver gently in it you should feel the pump turning causing a clatter against the screwdriver as you gently touch it against the internal fins

Has this always happened. Or have you had alterations done which has caused this. I don't know if there will be any 'back syphonage' occurring, i.e. if somewhere on the cold supply there is any open pipe which can suck air into the system under certain conditions?

Has this been a problem for a long time? What boiler do you have?

I came across similar on two installations. 1) The pump was on its way out and actually you could smell a burning smell. 2) Other occasion the pump was working at it's limit, Really only upstairs rads were getting piping hot others further on on thesystem were luke warm or cold. I...

Are the valves too long horizontally or vertically?

Thanks. For your information I opened the drain off fully and then ran the heating at the highest temperature possible. Suddenly there was a glug and a dollop of sludge seemed to be released.Thanks for your assistance.

Drain off under floor was used 2 weeks ago to drain off central heating system. Tried to use again but when drain off opened, nothing appears to happen. Any ideas how to solve this

I would try and nip up the pipe connctor first using an adjustable spanner

You have fitted the TRV on the wrong way round! Undo the compression joint in order to remove the TRV head. TRV head should be vertical not pointing out to the right as indicated on your photo. You may need to remove old PTFE and put on some more before refitting it. Before you connect the...

There is nothing wrong using compression joints on a system. You really only have one option in my view and that is to drain system. Remove the old radiator, then replace using either pushfit fittings or alternatively solder if you are sure there is no water left in pipes. The hassle of getting...

On the new Thermostatic Radiator Valves they can be fitted on either side of the radiator and therefore if it is actually fitted on the return end of the pipe it will have this effect

If it isn't that and it is either an airlock or sludge, could I attach a hosepipe to the drainoff and try and force the air bubble or sludge to move?

Thanks, I will try that
