The gate valve is opened only 1/2 a turn. Flow from boiler round heating loop takes about 20 seconds. With it opened any further, I have pumping over problems. If I DO add the 2 dedicated pipes, I will move the gate valve into the "flow" side. Ian.

Just added additional pipework suggestion. Anybody Please?

Some of you more experienced guys may know the colours. Perhaps the OP hasn't connected the "Live when valve open" return wire......read through his posts, he has a spare wire. Perhaps the valve is opening as it should. Then, when fully opened, it is supplying 240 v down the correct...

Hi Again. Problem with (sucking?) air in my system. I have a system which WAS gravity hot water, it is now fully pumped. I realise (thanks to this site) that it is piped very badly. Because of the layout of our nicely decorated house, it is impossible to re-plumb correctly. There is a...

Hi There. Not a heating / plumbing question......please bear with me...... I live in Sheffield. The council are currently insulating homes free in my area. 1) I'm booked in for additional roof insulation. (To top-up to current regs.) The company contracted for this work is Eaga...

Hi There. I live in Sheffield. The council are currently insulating homes free in my area. 1) I'm booked in for additional roof insulation. (To top-up to current regs.) The company contracted for this work is Eaga. Are they good / reliable? 2) The same company is coming at a later...

@ transam Plymouth Fury...... The John Carpenter book / film "Christine" was about a 1958 Plymouth Fury and a little bit of trouble caused by the car. Worth watching. http://www.youtube.com/watch?v=t9VpVQ1sMfk (Or is the OP a very angry man from Plymouth?) Ian.

Not really wanting to cut into my new suspended ceiling...... I've been in the loft and had a look round...... Currently at the top of the stairs is a 2 gang switch. One switch is the upstairs landing light......also switched from downstairs. The 2nd switch is for the bathroom light...

Hi There. My new bathroom steams up and I'm considering fitting / having an extractor fan fitted. I can do most of the fitting myself but would like to have final wiring done properly by an electrician. There is easy access in the loft for wiring a timed extractor to the lighting circuit...

Leave it in then? Seems to be working. Cheers. Ian.

Hi Again. Water header tank started overflowing today. Stripped ball cock valve. removed (very) dimpled pink washer. The only replacemant I had to hand was a black washer. Fitted it and all working fine. Just been out and bought some pink washers for spares...... Do I do the job...

I have exactly the same. Accept the fact that you'll have to remove the vanity unit, fit the panel, replace the vanity unit. You KNOW it's the only way. Easier than buggering about in the long run.

Water in header tank. Vent over not blocked. Cold feed not blocked. Just checked all those whilst checking loft / pipe insulation during recent weather. The air is not being sucked into the system via the ventover. That was one of my early thoughts. I have easy access to where the fill...

The system is currently protected with Sentinel X100 (about 2 years ago) What do you think to this suggestion. Drain system. Fit Magaclean. Fill system with a cleaning chemical (Any suggestions which?) Close all TRVs and lockshields. Open 1 rad at a time. Run heating until that...

Hi Again. I'm having to bleed air out of one of my radiators on a weekly basis. My boiler is not kettling. (It's an old Glowworm) About 30 years old. I'm running a fully pumped sysem wth zone valves for DHW and CH. I've heard that due to deposits in the boiler, bubbles of gas can be...

Before cutting the pipe above (A) to replace it, I decided to check if it was blocked by blowing down it. As I did this, I could see the level of water in the header tank go up. Hurrah! Releasing the pressure allowed the water back up the vent pipe in a rush. Bringing with it a...

Yes, the boiler DOES have an overheat stat. Ian.

The system is quite old, The reason for placing the valves where they are is due to the fact that it was pumped heating, gravity water originally, with DHW temperature controlled just by the boiler temperature. By having the valves fitted and running the system "properly", gas bills...
