Baxi 105 e prv

[2009mackerel]

I have a baxi 105e ,the CH and DHW have gone off ,the pressure is about 1.0 bar when i flick the PRV valve several times and re pressurize to around 1.5 bar the system works fine for about a day or two .Should I replace the PRV and if so what is the best way to drain and prime the primary side of the boiler,draining should be ok it is the priming not a 100% sure of.

You have no clue of what is actually wrong. Get a GSR

 

[tommytoker]

if the prv is passing and making the pressure drop then it needs replacing
if you know how to re-pressurize with the filling loop then thats all you need to do once replaced

Changed the PRV re-pressurized boiler working fine.

No it's not it went off again , re-set
the boiler and it went on again , any ideas ?

Call a gas safe enginner.

You obviously dangerous and work on boilers when you shouldn't

I told you it's going to be a quick and cheap fix

You've just wasted money now

Fool!
