calling all plumbers - urgent help needed!

[Black Sheep]

If I close both isolation valves (by turning the screws with a screw driver) will the rest of the heating in the house still work? Or does the water have to flow through this bit too? Sorry, but I don't really know how the heating system even works eg. radiators etc.

We've just had our entire system replaced so that now turning off one radiator will not stop the rest of the system working.

previously it had what is referred to as a single pipe system. This is where a single pipe winds its way round your house with spurs off to each radiator, so the first radiator on the circuit will get the full heat from the boiler the last will just be full of cool water put back into the pipe by the previous rads. There should always be a pipe that works as a bypass for the radiator, some of ours didn't and the radiator was the only link in the chain.

now we have a two pipe circuit, hot water pipe to each radiator, cold water return, so all radiators get the full effect of the boiler (a bit of cooling happens on the longer distance rooms from the boiler, but it's not noticeable)

the latter is the better and more likely to be fitted.

called in the plumber - but they can't come until Jan!

Will drain the system tonight and then leave until jan.

Unfortunately, the isolation value is the source of the leak so can't just close it!

Shame I didn't see this earlier, before the shops shut. the valve is part of your hose, cost about £15 and an easy DIY job. Mind you, b and q or similar will be open tomorrow and they sell them, take you old one tho, they come in different lengths.

the problem is I can't get to the other end of the flexible hoses without removing the whole lot of kitchen units and disconnecting the gas hob!

Unfortunately the valve is part of the hose, if its absolutely necessary to disconnect the gas then a gas engineer will be needed, not a plumber. If not, then DIY and save money.

If it's modern the gas may well be connected via a bayonet fitting.

Any doubts get a 'gas safe' registered person in - it's not uncommon for plumbers to hold this certification.

With careful disassembly you should be able to slide out a cabinet to access the flexi without too much messing about. Maybe the adjacent cabinet will allow enough access to save disturbing the hob.

And a plumber who holds the cert is registered as a 'gas engineer'.good point about the bayonet fitting, I tend not to use them but some do.

all fixed thanks to a local plumber this morning - cost £115 which I'm very pleased about.

Thanks for everyone's advice and help yesterday
