Hi

I have an unvented Ariston Genus 27 RFFI system boiler with an unvented Ariston Super Bravo cylinder. The problem with the boiler is that there was no pressure and I believed therefore the boiler did not fire up. I think this is due to a leak in the system, but last week Pimlico Plumbers came over and after less than 5 minutes said that it was the gas control valve that was faulty and needed replacing becasue it won't fire up. He drained the system and replaced the valve and also the auto air vent which was leaking.

After two days of replacing the faulty items, the pressure has again dropped to 0.8 (should be between 1 and 2) and the pipes are beginning to rattle whenever someone takes a bath or runs the water.

Please correct me if I am wrong but I believe if the pressure drops to zero, the gas control valve is designed, for safety reasons, to ensure the boiler does not fire up.

Help!

Thanks

Hi,

I guess that you are in central London.

Get Pimlico back - I would hope that they offer some guarantee on their work. Check the small print on your copy of the invoice. Also, ask to see the engineers Corgi details.

If you don't get timely satisfaction, ask to speak to the boss. He was on the posh plumbers TV program recently.

How did you pay? By credit card? You might be able to withhold payment if you feel so inclined...

I know one plumber in London who makes a point of phoning his customers 2-3 days later to ask if they are happy / had any problems - particularly relevant with central heating. There is no cost for this or if any fine tuning is required. He is a better plumber for this feedback!

Hope this helps.

Sounds like your problem is a small leak, posibly on a rad valve, as Ian suggested get them back under guarantee.

I would also suggest that the gas valve was not at fault as you say, the valve is designed to not work in a low pressure situation.

I am working in the Chelsea/kensington area so drop me an email with your contact details and I may be able to check it out for you.

Shall only be online at weekends.
