Worcestor 28i

[Soggy_weetabix]

I repair Worcestors a lot but I having a problem with (I think) the customer as opposed to the boiler.

Replaced PRV July 06 (filling loop letting by). 6 Months later customer informs me PRV has gone again.

Replaced under guarantee.

Filling loop disconnected, ex/vessel still holding approx 1bar charge and working and 2 months later same fault.

Customer states pressure has never risen above 2 bar when system is at max temp.

Replace again, and today (a month later) ...same fault.

Am I overlooking something stoopid here?

Mains not entering via plate by the way - checked it.

I really think its over pressurisation by customer but he catagorically (sic) he has never done that.

Any ideas?

Unless the pipe to the vessel is blocked but as you know the pressure would have to get to 3 bar still.

Unless of course its a faulty guage

p.s 1000!

As you all know I don't usually touch Worcesters other than basic servicing, but I have had 2 this week where the pressure gauge has a mind of its own

The cavity behind where the guage connects blocks, too. 4mm screwdriver drills it out!
