By draining out half of the rad and opening up the rad valves without venting leaving half rad full of air makes a temporary expansion vessel! i wouldnt leave it for long!

I want to fit 4 spot lights in bathroom ! there is an existing ceiling rose with pull cord switch! Can anyone explain how to wire it up. Do i use existing rose for first spot then spur off that to each spot???????????

ChrisR you ****in muppet! Its got sod all to do with the size of the boiler more like if you had an 8 bedroom mansion you would probably use 28mm circs!on the whole every boiler works off 22mm circs irrespective of what boiler it is as long as it is piped up right. There is always the option of...

Has it always done it

The expansion vessel could have knackered you need to drain down system and check charge pressure on the top of the vessel it should be between 0.5 and 1bar if not recharge then refill boiler or the diagphram inside could be split hence add a new vessel onto system.One way to check if its the...

What system have you got ?From what i can gather it is open vented to start with! Is it fully pumped or pumped heating gravity hot water?

Muckylugs you should of called yourself MUPPET i wouldnt come in after you and comission the boiler just because your so tight and cant get a proper fitter to do the lot> I wouldnt put my name down on a job that some other ARTHER JOB HAS STARTED!!!!!!!!!!!!!!!!!!!!

Get a bloody proper gas man in who can use a multimeter and see if its wired up wrong. For all the time you are ****ing about trying to fix it you could be at work doing overtime hence being able to afford to pay for a proper engineer :shock:

It sounds like either your expansion vessel is flat and needs recharching again! id put my house on it! 8)

can i wire a security light of a socket of the ring and what size swithched fused spur do i need. also what are the regulations on an outside security light?

Too make things easier how do i calculate a voltage drop from the consumer unit to the first socket on the ring or for example 20m of cable on a radial circuit using 2.5mm2 cable ?

do you mean the cable length from consumer unit and back should be 100m max in length? also how do you work out the volt drop across the ring main?

firstly I would get the system powerflushed .The pump can be checked to see if it needs replacing irespective of whether it is turning properly by checking the resistance between the live and neutral on the pump(a good pump should be 220 and a pump on its way out could be 100 and lower) The...

What is the maximum permissable length of a 2.5mm2 cable on a ring main with a 32a mcb and does it matter how many sockets are fitted as long as you are within the limits?
