No I can't stand mucky jobs. I explain to people that my job as a plumber is to contain liquid within a series of vessels......not to spread liquid over walls etc.

I don't like painting,plastering, tiling, bricking etc. they are the opposite of what I learned. They spread sh**...........I contain it!!

I would say its a 15 litre job. First port of call is get your hands on the mi's for the water heater and follow it to the letter.

Get the manufacturer instructions (MI's) as has already been stated. Follow the requirements too the letter. Cant see a prv on the pipework in the photo. An expansion vessel may not be required depending on how long the cold supply pipe is before another outlet, before which there will need to be a check valve to prevent contamination of the water categories. Oh and ditch those nasty flexi's and hard pipe to the heater.

Some manufacturers insist on flexies to be used for the connections to the heater.

True enough. Hence source MI, s and follow to the letter. But if not necessary then ditch them. Quite how they are aloud that close I dont know you wouldnt put them that close to a boiler and you certainly wouldnt use them to connect up to a standard unvented cylinder.

Which is why i dont like the unvented cylinders that come with a flexi to connect the expansion vessel.

Agreed. It seems strange that so many of the gas regs seem to be suspended the minute the pipes and cables enter the appliance. Distance to electrical cables materials used within set distance of combustion etc.

So without MI what would be your method?
i have an expansion vessel, I'm sure I need a non-return valve...
what I'm asking is how should this look when I'm finished?
I appreciate all the feed back
