The lettings agency we look after also have about 30 or so. But they don't get serviced although I do pick up work from these, vessels and immersion mainly.

My renewal cost me almost £200. Not hard to get the £40 per year back again. The way I look at it, one install will pay that straight away, so worth it even for plumber who only does the odd unvented job. And servicing is usually not hard graft.
£89.00 a service in London (+ parking)
I have never been called to just service a cylinder... I will normally just isolate mains & recharge vessel if a custard has an unvented & add on a small amount to boiler service! I ain't lifting the prvs as they will drip & I will get a call back! I also ain't dismantling the prv to check the line strainer!!
So that is why you are not doing unvented servicing, if you don't pull the T&P & the pressure relief valves it has not been serviced and no they are not like dirty heating systems with 3bar safeties fitted they don't drip.
Well at least only very very very occasionally and of course you have warned the customer any way.
Thats it you know whats going to happen on the next you go out to Best !!!

Me either. It's one of those apocryphal stories that everyone believes but have never seen happen.[emoji6]
How can you verify operation of the valve without testing it?
Which is why we do it eh best. Plus my servicing record asks if the valves operate.
They are the most important safety parts on a unvented, particularly the p&t relief, is the way I look at it. I have a bad habit of playing with them valves knobs when I have a look in at the units. It's going to bite me someday! :grin:
Went to change a vessel on Sunday night. Student flats, this company has roughly afew thousand cylinders throughout uk. They don't bother servicing them, repairs in the week get left to the maintenance man.
The vessel that had blown was a grey coloured heating type bought from screwfix.....
After changing it, I look down and see a lot of scale around a concealed type tundish. I then realise that the t&p is flowing like a tap. How's your hot water I ask? "Not very good, it runs out before the end of a shower"!
210litre cylinder.....
5/6 people rely on this for hot water but they aren't prepared to have the serviced. Or repaired by anybody certified
