Thank you Terry, I will check it tonight.

Thank you. I will check it this evening. Do you know what the pressure is supposed to be?

Thanks Terry. Does the ev have a Schraeder valve so I can check the air pressure?

Thank you Terry. Only turned the heating system on last night for a test run so only noticed it last night. I have left it off until I get home from work then I will try it again to seen if there are any other clues. Surely a pressure vessel defect would cause a pressure drop?

Hi, I have a Vaillant eco tech plus combi boiler. It works okay for hot water but I am having problems with heating. When the heating is on the system pressure starts to rise slowly. I have it set midway in the grey zone on the gauge but with the heating on it slowly creeps up through the red...

I have recently replaced an interior door but have a problem. When not closed it swings open but I want it to swing closed. Can anyone tell me how to achieve this? Many thanks. Tim.

What I was after was a 17th Edition regulation referring to what could be added to lighting circuit. I realise that bathroom extract fans can be added to the lighting circuit but I wanted to know what the rules are. I am working on cabins that have a 6A MCB with 1.5 mm wire feeding the main...

Many thanks for the reply. Do you know which regs refer. I am having a difference of opinion and want ammunition to further my argument. Tim.

Can anyone tell me what the rules are regarding connecting extract fans to lighting circuits. I was once told it was acceptable in certain situations but can find no reference in the 16th or 17th Edition regulations. Tim.

Can anyone help me with a generator question. If the plate on a 3 phase alternator on a genset states 88kVa 122A does that mean 122 A per phase or 122/3 A per phase? Many thanks Tim

Help, I am going to be fitting a new kitchen soon. Can I fit an under sink electric water heater and connect it to the existing socket ring circuit? Is it legal and is it safe? Does anyone know a good trick for adding sockets to a ring circuit without replacing the cables back to the...

Are you allowed to connect lightning protection to earth bonding system. I work overseas and haven't got any reference books to check the 17th edition rules but I would have thought it to be a potentially dangerous practice. I thought I had better check the facts before I tell our contractors...

I work in a place where most of our equipment is supplied by generators. As a result earthing is achieved by connection back to the generator and it's earth/neutral link. For some reason all the generators and equipment supplied have also got earthing electrodes (rod types) fitted. I work in...

Pardon me for being a dumbass but I am not totally sure. I am an electrician and only moved in to the house two weeks ago. Up to now I have been all electric. I do know that I don,t have a combi boiler and the system I have got is ten years old and no longer allowed to be istalled as it is not...

I am changing a radiator. I know I can isolate both sides with the stop valves to remove it but can I change the discharge valve to a thermostatically controlled one without draining the whole system down. Many thanks Tim

I have just moved into a house that needs a fair bit of work doing on the central heating system. It is gas at the moment but I am wondering whether to go all electric. Some points to consider are pipework around the house, availability of gas supplies in the future, price of gas in the...

It is over a length of about 50 metres.

I want to put in a 50 metre fence but the ground is not flat. It is on a hump that goes up about half a metre to the middle then curves down for about a metre. Does any one have any advice on how to do the job so it doesn't look too crap. I want to use concrete fence posts and propably...

Are there any gas boffins out there? I have just moved in to a house with gas central heating. I have allways been all electric so I need to know a few things about the new system. 1. What do I need to do to maintain the system in a healthy state. 2. Why is my system operating strangely...
