Pressure relief pipework

[mazzy2000]

I recently had a service carried out on my boiler and the engineer said that the pressure relief pipework was non compliant as part of it was plastic, not all copper. Also, there was no turnback against the external wall (just ejected out over the garden).

Is this correct? Which regulations govern this? There is no guidelines given in the boiler installation manual.

I believe I have the skills to correct this myself, but if it does have to be all copper pipe, can I use the plastic speedfit elbows and connectors etc?

No you can not use plastic speedfit fittings for this it must be solderd or compression fittings and yes it must turn back down the wall as to prevent it firing straight out the wall onto someone walking past.

its an unsafe plumbing defect so wont be covered by any gas reg, and as its not a gas reg you'd be quite right to try and rectify it yourself if you wanted to.
renew whats done in plastic with copper and easier for yourself to use compression fittings, once out in the garden put 2 elbows to form a U shape returned back into the wall

Thanks for the comments, got it sorted now by local plumbing/heating engineer.
