Baxi combi pressure issue

[armyash]

Looking at a baxi combi tonight. Pressure drops to 0.2 but will go up quite high when running on CH. Needs repressurising regularly.

I don't have a lot of info yet but what could cause this?

I'm going to check prv and ex vessel anything else I should look at?

Thanks

Maybe?

Thanks Harvest Fields.

Pressed schraeder valve, no water but no air either. Couldnt recharge because my pump was broken.

Would this cause the same symptoms?

Represurise it and tell the customer it might be ok , if it wont hold charge its time for a new one

Make sure you drop the pressure out of the system first mate.

But you know what I mean. You cannot top it up even if there is only a bit in the system.

 

[armyash]

Yes thanks I'll use the boiler drain off.

Recharged last night, ran it on max until it went up, usual rise on gauge from 1bar. Not heard back, fingers crossed.

I use to say that now can' be bothered just tell them get new one.

Must admit to getting a bit the same, because you take the time to repressurise it and it fails to cure it 2/3days later ,then they never expect to pay for one of the visits
