Hep20 replacement query

[shd1970]

I have a new radiator to fit at the end of this hep20 connector (there is obviously a second one out of shot of my photo !)



The builder used this push fit to go from copper down to plastic as you can see, and then at the radiator end there is copper in the wall so additional push fits in the ceiling that I can’t get to

As these connectors have been in place for 15 years, I already have the floor up and as mentioned, I need to do some copper pipework at the far end for the new radiator, I’m therefore contemplating replacing these for the sake of a few quid

Can anyone confirm please whether these hep20 connectors have teeth inside along with a rubber seal/washer similar to the John guest push fits that I am more familiar with and thus will there be any damage to the plastic pipe you can see when I remove them , and can I simply replace with an exact Hep20, John Guest or any other equivalent or will the plastic pipe be damaged and a section need to be replaced, please ?

To put it another way, how many times can you connect to plastic pipes using push fit?

I just see it as an opportunity considering as mentioned these connectors have been under the floor for 15 years and even though likely will last another 15 years it just seems like too good an opportunity to miss to replace when I’m going to have to drain the central heating anyway to do my pipework and know that these legs are both bone dry

Many thanks in advance for any replies

The connectors do have a toothed ring in order to precent slipping off, however these won’t damage the pipe to that extent. You should be ok replacing like for like or use any other fitting. If you are concerned about the fittings been 15 years (and rightly so) I don’t understand why you’re not concerned about the plastic pipe, this surly will also be 15 years old and is subject to just as much ageing as the connectors, personally I would replace the lot .

HEP2O has a 50 year warranty/guarantee according to the makers, Wavin. So another 35 years to go...

That is the most recent variant of fitting, too. My house has loads of the old grey version, and is only slightly older in construction terms.

Thanks for your reply @slawit

Don’t get me wrong I would love to replace all of the plastic pipe on that run, but the problem is it’s fitted in the ceiling of a single story extension so I can’t get to it
I can only get to the push fit joints where that radiator is tapped off the main system
I’d have to chop some substantial holes in the ceiling, which obviously makes no sense

I will get a proper HEP removal key to get them off just make sure I clean the pipes up nicely and then put some new ones back on
