Best plastic fittings

[Norcon]

Can't you answer the question deary?


Why not compression on gas? Oring based joints are fine.

Come on Mr expert.

O ring joints are a long way from being fine.
They suffer from abrasion, compression set, chemical degradation,explosive decompression, extrusion, outgassing/extraction, over compression, plasma degradation, spiral failure, thermal degradation, and of course installation damage.
Only a couple of those can be linked to a compression joint.

Been trawling google again nobhead? http://www.rlhudson.com/O-Ring Book/diagnosing-causes.html
Pathetic
Explosive decompression haha what has that got to do with o-rings on a plumbing system?

Still not sure if I should use compression or push fit to Tee off the 22mm yet. Lol

Use push fit, that's what they are designed and tested for. Ignore the scaremongering.

Their not tested for longevity and won't pass that test.

No but it looks like you've been.

quite a few old systems round here on the old acorn pushfit aka hep20. some as old as 20+year, on sealed systems with no probs. albeit im forever replacing pinholed copper pipe. very aggressive water in theses parts.

I googled to prove a point that all you are is a google warrior who uses the first page he see's as reference for your information. Strange coincidence that you list of o-ring failures is exactly the same

You are also a hypocrite you belittle Dan for mentioning gas carrying systems and that it has no relevance to domestic plumbing system and then spout off your list explosive decompression hahaha
You also avoid questions that show you up such as what your experience is

I'll give you 1 thing though, you are a very good troll if nothing else.

Fair point holty, I can only comment from experience of jobs I've been called to. Some boiler manufacturers will now specify the water quality for their products, so in terms of heating systems I'd still install copper rather than plastic. But for hot and cold services, that would be where I would start considering alternatives. Although saying that, it all usually depends on how well the flux residues have been flushed out of copper piped systems.

I have encountered a site in N Yorks, where copper pipework started pin-holing quite badly shortly after the cold water services were boosted on site (by a previous company). After a lot of research and water quality samples sent off for testing (came back ok), the only thing I could put it down to was well oxygenated water (caused by filling the break tank with a 2" float valve).[/list]

Industry standard!
O rings are sub standard and will never beat a mechanical compression joint.

I think we established in past threads that non corn is at best some knuckle dragging site basher, most likely a failed kitchen fitter.

He's certainly the only one suggesting compression fittings which I guess makes him "special" .

Most professional would avoid visible plastic/push fit like the plague due to how horrible it looks, but as for longevity. ... decent quality gear fitted as per the instructions is fine.



Notice also that non corn hasn't managed to answer any questions posed.

Which O ring based joints just isn't.

 

[Dean744PiN5]

Agreed and judging by his previous posts he has never contributed anything of use to this forum.

And he still can't answer direct questions

So come on nobcorn what did you/do you do for a living?

Notice that Norcon keeps his/her profile private. Something to hide maybe? Professionals who are keen to show off their work and offer professional advice would surely have nothing to hide.

Their second half of their profile name describes the quality of their advice that I've seen so far!

NOUB.

Why don't you post up the hash jobs you've done with push fits?
