as I said earlier --- Sounds like its taking time to ignite the gas - could be a weak spark or the probes or leads need cleaning.

I had a job where the leak couldnt be found and the customer was topping up the system every two days, went all over the system looking for the leak, but it wasnt on the system, it wasnt the prv either. Finally checked the heat exchanger to see water in the tray below but the high temperature of...

I agree with Nige, It could well be a piece of loose solder or some thing in the pipe. Strip it out and run that section in Hep2o.

They are cheap and cheerful in my opinon.

Roughly how much should i be quoted for a full htg system with a Vaillant condensing combi. 3 bedroom in Enfield , North London.. _______________________________ lynda, moderator please note forum rule 9

Just drop the pressure in the system . You can swap the valve without draining down if you do it quickly, just have plenty of towels just incase.

Do you know if they had a curry the night before > :shock:

Try checking the expansion tank in the loft , the ball valve could be stuck, maybe theres no water in system .

Exactly as you said . Shut flow and return valves on the boiler . Drain boiler and fit your new valve . Done . 20 mins tops .

How do you know the pipework did'nt like it .

hi - yes cut the NRV into the hot supply before the eq valve

Why whats wrong with that ? ive got a combi and two bathrooms , i can run both showers at the same time no problem. 828 Vaillant

Dont try the pump on speed no 1 - this boiler is a combi and will need to be set higher as per manufacturers instructions .

you could fit a non return valve on the outlet of the hot water cylinder , that way - no water will go back up to the tank via the cold feed . Also if you fit any other mixers on the system this will solve any further problems.

Your valves are def fitted the wrong way round. But more common is that the boiler has been renewed recently and the flow and return pipes have been connected the wrong way round - thus the water is flowing backwards round the system .
