Plumber in Liverpool?

As a favor for a friend, does anyone know a tame plumber in Liverpool?
The prv on their hotwater tank is weeping and needs changing.
Combined over-temp and pressure to be exact.

Are you sure its not over pressuring due to temperature being to high ? I presume its an unvented cylinder, so you will need a plumber with the
relevant unvented ticket. I'm to far South.

Or it could be the expansion vessel, best thing to do is get somebody to check it over and diagnose it correctly before replacing parts

Your right, it does want a check-over including checking for air in the expansion vessel.
However it weeps constantly always, even when its not heating and the hot taps been run and its not anywhere near being over-temp, and at varying
amount depending on how well it seats after you vent. So unless the whole main (its a flat on the top floor of a managed block) is over pressure and
has been for the 3 months they 'have not had hot water in the afternoon' then its the valve.
It also looks about period for being 25 years old and ripe for replacement, as likely, is the expansion vessel!

Had a look again at the weekend and there is a pressure gauge on the system, which reads about .25bar under the setting of the cold-side prv (3.5 or
4bar I cant remember) but well under the combined prv and temp on the hotside. So doubt its that.

ANYWAY; apparently the man came today, had a look, turned the two immersion heaters down 'from 40 to 30' and told them to see what its like
tomorrow. While also muttering it should be above 50 to kill legionnaires.
Now the adjuster might be a bit out, but 30 seems really cold to me, and I could well believe it was set to 40 before as even in the morning you could
basically run the water directly out of the cylinder for a shower without mixing any cold.
He didnt check the expansion vessel.

I think he has tried to bodge it, and needs to come back tomorrow even if its not leaking, which I expect it still will. New valve, new expansion
vessel, and while the immersions up to 55c.
