Hi All,

I'm replacing our own Main Avon multipoint water heater with a newer
Main Medway jobby.
...
So, I can either move them all in soldered copper, use compression
copper fittings or for the water at least use flexible tap connectors?
(Can they also be used for gas out of interest .. considering much
gas plumbing is in plastic these days (in the road at least!)) ;-)

They're absolutely prohibited for gas use.

Ok, thanks (I'd guessed as much) and why I phrased it like I did. But
fine for the water heater connectors though John? I was more unsure
about the flow rate but as they are already elsewhere in the system
I'm not sure it's that relevant? Are there some that offer less
resistance (for the same nominal connection size) would you know
please? The bottom line is final flow rate is probably more a function
of the heater stat than any pipework.

To be honest it really doesn't
sound as if you have the competence to do this job if you're asking
questions like this.

You are probably right. However I did re-plumb (water and gas) and
wire this house when I bought it ~30 years ago and it's all been ok so
far (could just be just luck I guess)? ;-)

I suggest you get in a qualified (i.e. CORGI) fitter

Yeah, I helped one of them bleed his radiator .. he'd been on it an
hour apparently! ;-)

to ensure the gas pipework, ventilation and flueing are sound.

It's my house and trust me, there is no one more keen to ensure all
those points are correct than I am. BTW, I've ordered a new flue and
case seal, just because.

They may be
happy for you to DIY non-gas parts of the work but if it were me I'd want
to be involved from the outset rather than asked to come in and sign off
someone else's work.

As it happens he will be here for all the key stages (he's just not
about today) .. like I said, I want it right .. ;-)

All the best ..
