Any one ever changed one or stripped the cylnder out of one of these ,,acording to tech help will have to remove cylnder from boiler replacing all seals i disturb take out remake fitting,sounds a bit of a arse to me.

Customers wants a rough estimate so any one have any more informed idea of how long it might take.

If u don't have unvented ticket nock the job back.

It's a tpr valve, allow a morning if you aren't familiar 1hr if you are.

Must have ticket to work on it.

There are plenty of other jobs if you aren't qualified for this one.

I went to a hotel explosion other day a plumber had fitted 400ltrs of unvented storage with a central heating ev and a gas cock between it and the cylinders.

Yes, shouldn't be too bad, they are heavy large critters though and held together by a combination of spindly bits which as a whole supports the weight.

There is a relevant recall about the mounting brackets which is a very small problem but might be relevant to your boiler.
