Guys advice please, I had a leak from radiator and my ceiling came down. One of the joints in the ceiling looked greenish so plumber suggested to change that joint before I replaster. Was probably green from the radiator water but I don't know.  Anyway he put a hep20 push fit when I assumed he would put what was originally there yorkshire joint. He said he can come back at no expense to me to change to yorkshire but he said hep20 push fit is far superior.not sure I trust a push fit that won't be accessible in my ceiling. Don't want another leak there. Last joint been there 50 years and wasn't leaking. 

Is it possible to avoid having a joint there at all?

the green is showing corrosion of the copper ,probaly caused by the joint not being wiped clean of any flux when it was installed  and over time it corroded through the pipe 

 toput it incontext  the push fit joints have seals have viton seals ,used much in the motor industry  and has a life span of about 50 years .

 there are systems of non copper piping that you can get in 100m rols so not joints need to be hidden 

but that would involve a BIG job replcaing all the copper 

the down side is if you have mice and htings in hidden spaces ,they love to chew the plastic piping

 there are now copper fitting that do not need ot be soldered and can be clamped with an expensive tool  and ti might struggle in tight places to get it on .

 or you could use compression fittings  and keep to copper .

lots of choices

one example of a crimping too; for copper fittings --these fittings are not same as a yorkshire fitting 

So long as you don't damage the seal or pipe Hep2O fittings are bullet proof. 

 

If it's not leaking after pressurising the system then it'll last for decades.

I would not disagree

  but a rough cut on copper ,not using a pipe cutter and not smotthed up with emery paper and you could damage seal  which could fail later 

you just have to think about what you are doing

If a rotary pipe “slice” was used to cut the pipe then it would already have turned the end of the pipe inwards, removing any abrupt shoulder that is often the cause of a damaged rubber o ring.

If the old joint was desoldered then defo would need a good clean back to copper and the burrs removing. 
 

That all assumed ok, as it’s going to leak from day 1 if so damaged, then you can relax. Hep2O stuff is excellent for quality, robustness, and an effective long-term solution here.

 

Where did the leak come from then? The radiator valve?

Yea it came down from the radiator valve. That's been sorted. I was advised to change that joint as it corrosion was there all green before I replaster the ceiling back and have another leak in the future.  

 

My dad isn't happy with plastic very older school and wants soldered yorkshire joint on there instead. Plumber said he will come back and do it. I wasn't sure what you guys reckon is better. Hep20 push fit or copper soldered. We plan on living her for decades and deceased yet so want the best one that will last

both fitted correctly will perform as good as each other

Ok thanks I'm not into plumbing at all... my dad is but is 80 years so doesn't like plastic as he doesn't know anything about them. Only knows copper fittings. It's under flooring and not accessible thats why he doesn't want plastic push fit. So looks like he will get the plumber back to change it to the copper one. 

I am old but a plastic convert, as said above if fitted properly there is no reason plastic will fail before copper.

Not all plastic push fit is equal. 

 

Some is utter rubbish. 

 

Hep2O however is top quality.

Copper is the ultimate, but I would feel bad not covering the plumbers time if he's not done anything wrong (at least some beer money if nothing else).
