How long do you think that would hold on a central heating system that has the filling loop left open accidentally?
3 1/2 bar on one of those pex/soddered fittings? I think not

If you forgot this part of the process maybe;

So it's like the uponor... But worse

I use this allready, its same as uponor q and e system. They don't show the shrink ring which holds it in place. And I test it to 10bar! But i don't use sharks tooth fittings!! :smile5:

Why do they call it soddering again? sounds too kinky and bum lovey for my liking

 

[zzzjim]

Why do they call it soddering

Its similar to what happens to the L in Aluminium Sidings !

Soddering wire , no its just Sodder !

 

[townfanjon]

What on earth is 'soddering'?

I think it's got something to do with dogging !!!

Looks a bit like the pipe I used to use in Perth,we brazed the adaptors onto the copper,and joined on with crimp fit,or rehau,where you expand the pipe,and ratchet a brass ring on.The Rehau system never leaked,even with 20 bar in it.

Funny you said that erm,in Perth no meter governor,but all appliances had separate governor,pain on 1st fixing hot plate had to allow space for governor,fitted with flared unions,water heaters over there had no expansion vessel just a prv which would drip when hot
