speed fit on secondary return

[sheff paul]

Just changing some dodgy waste pipes on a dubious bathroom job installed by a DIYer putting speed fit in as some has already been fitted in for some time before ,then notice's the unvented has a secondary return fitted.Do I finish it off in plastic and get done for lunch,or do I rip it all out and get home late,this job is a favour money free one.Has anyone fitted platic on a secondary return set up,yes I know you should not use it.

personally if the manufacturers say dont use it, I wouldnt, as come the day it fails, you are in the pooh as the installer who has to defend your actions.

Simples.

You lot still arguing about this?!?

It's Sunday evening, who gives a tish!!!

Stop trying to keep your post count up Tom!

 

[Howsie]

the manufacturers say no to a return that"s on 24 hours a day why would you install a system that runs through the night, it should also be on a stat to stop the pump running needlessly, then again you would know that being an experienced plumber

And you're point being?

Can you use flexi's on systems that have a secondary return ??:lol:

Im sure they would be less able to cope with hot water passing close by 24 hrs a day ! !

 

[zzzjim]

If it leeched into water it would be banned

Ok , this may not be exact failure mechanism

( A bit of O2 oxidation , a pinch of Chlorine/Florine ,and some plain old heat-creep )
( external paint / vehicle fumes etc )

Most of the problem is it may have a long 8hr shift
-Hot all day long For Chemicals

But they aren't part of the 'loop' as I'm sure they'd fail.
