What is your preferred method?

Understood- shower pumps or processors aren’t temporary though. The house I’m working in at the moment has I beams on each floor. There are holes along each beam that you knock out with a hammer for services. In this instance push fit or press fit is the only option to get pipes through as notching isn’t permitted. I do agree though, it does devalue our trade.

Trust me though, if an OEM fitting fails on a shower unit, it will come back to you in the same way if a fitting fails under a floor

In cases like I beams or metal web joists there is not a choice so I will use it there, but it allows you to get from point to point with minimal fittings.
But for altering existing copper pipe work I much prefer the old well tested way, it’s no slower really, even on rad alterations, I haven’t drained a heating system in years and solder on the pipework with a cork and carrot.

Absolutely I prefer end feed too.

Yes I bung open vented systems too. Amazing that there are still people out there who don’t know about it.

Thanks for the input fellas
I thought that this would be a mine field.....and I think I've been proven right!
So I thought I would give the 22mm NMP a go as what I will spending in additional product I will be saving in labour.
However it seems like the stuff is harder to come by than Rocking Horse......(you get the picture)
I've managed to find a supplier so we'll see how it goes.
