Pilot Light

[snorkel1234]

Pilot light keeps dying on me, had gas fitter replace thermocouple and after a month the problem has once again arrisen.
The only other problem I can foresee is a faulty gas valve.
The problem is that I would like to purchase the gas valve myself and then get a Corgi engineer to install the valve myself as I have heard how people have been ripped off in the past. It is a old Baxi Bermuda I think 45/4 the gas valves grey push button is below the regulator, and the gas inlet pipe is at the rear of the gas valve if this helps where could I source one if it is the gas valve

Do not buy a new gas valve. I've never changed a gas valve due pilot problems.

Is it the correct thermocouple - universal types may not position the thermocouple tip in the right place.

Is the pilot injector clear and producing a crisp blue flame.

Are the pilot connections OK or leaking slightly?

Is the pilot adjusted correctly?

Is the gas valve inlet filter partially blocked?

Is the sight glass cracked/missing?

etc.

etc.

Get the fitter back to sort out the problem or find someone else.

Make sure the ventillation is calculated and checked, the flue is smoke/spillage tested etc.

Back boilers cause more carbon monoixide incidents than any other boiler type.

I have had lots over the years but only change the magnetic power unit.

(about £15)

I've had a few too but always replace the gas valve. Lots of heating guys are a bit dubious about fitting parts of unknown origin.

I thought the magneto was not changeable on the V4600 gas valve.

as far as i was aware its changable but not legal to do so . Not aloud to open up gas valve's either when they fail a tightness test if the seats not sealing.

Often its just the centre contact on the gas valve thermocouple solenoid unit that requires cleaning up.

It sounds as if this fellow is trying to save money by buying parts for some CORGI to fit.

If does that then he absolves the CORGI of any responsibility for wrongly diagnosing the problem.

If I did not understand boilers then I would employ an expert and hold him responsible for correctly dignosing the problem for me.
