Flexible 22mm Copper Pipe use with Combi Boiler

[ZP]

Please advise.
I am changing my combi boiler, the flow & return on the new replacement combi are on different sides to that of the old existing one. To make life easier, is it acceptable to use 22mm easy bend (ridges on it type) copper pipe (available from B&Q in 2 foot sections) for the final lead up to the boiler ?
Presumably plastic and flexible braided types are no good.

ZP.

if you were competent to install boilers I guess you would know

the first 1m must be copper, best not to use flexi's.

how are you doing the gas and flue?

with an extractor hose probably

and don't forget the garden hose to connect up the gas

Not use flexi ?
Is this because regulations ban it ? or is it more likely to be damaged/ or get a pinhole etc...?
My gut instinct is to use std 22mm pipe soldered, but the re-routing work will be tight and difficult, hence why i was considering the flexi type...

If you can't carry out simple pipe soldering then it doesn't bode well for a safe and sucessful installation....law says you need to be competent and you clearly aren't.

You'll get little help on this forum....diy boiler installs are discouraged.

Personally i'd use a 32mm waffle valve connected to the 22mm copper pipe work. Id make sure the waffle valve is protected by a cheese wheel preferably cotton coated to avoid the smell. Dont forget to add some inhibitions to the system too and carry out a Wellness test on the gas line.


Or just pay someone who knows what they are doing!

Incomplete advice

The garden hose must be YELLOW in colour

Will probably get a local corgi fitter to do final gas connection and flue.

Good luck finding someone willing to finish and certify your (not so) handywork.

Sadly my not unreasonable question is being riddiculed, I am sorry I joined the forum to ask for any advice.
I have worked on my 2 home central heating systems over many years in the past, successfully fitted many radiators, serviced my old boilers, I make a perfect soldered joint - as good as any tradesman.
I will find out from other sources if copper flexi pipe is suitable, if not then I will use std copper.

no self respecting tradesman would use flexi connections. Have u heard of pipebenders? What your doing is illegal.
