Hep2o to JG speed fit

[ipbr21054]

Hi,
Please see photo supplied.

The existing grey pipes were cut into and a radiator was added,hence copper pipes on floor.
The fittings look like Hep2o and i wish to use JG speedfit to match my other work im currently doing.

So im going to erect a wooden frame wall say 8 inches to the left of those grey pipes and the wall will be where you see the blue writing on the floor.

I need to somehow undo these 2 fittings & cap them off "T piece connections will stay" so i can make my new pipe route and continue.

The left pipe i can get off quickly & cap but the right pipe doesnt seem to have much to pipe to play with.

Im not draining down the CH but doing it in situ so im not sure how to tackle the right pipe.
These swivel / rotate fine but now the left one needs to be shorter thean the right one where currently its the other way.

A hep removal tool or 2 flat bladed screwdrivers pushed into the collet and pull pipe out, only do this when you have drained down though, i certainly wouldn’t be doing it live.

Why wouldnt you do it when live ?
I know there is water in the pipe but you should be able to put your finger over it quick enough.

Its just my preference, sometimes you can just drain a leg depending on what system and how you tackle it, but if it’s a combi there could be some pressure behind that, if you don’t do it properly.

If the flow is from the plastic to copper, just squeeze the plastic.
Job done.

I’m thinking of cutting out those two t pieces and replacing them BUT can I use JG speed fit with that grey pipe ?

I can’t see it being a problem.

The outside diameters of the plastic pipes is the same, however the internal diameters are not.....hence you need the correct insert to suit the pipe. Too tight and the pipe may swell (if hammered in for example), too slack and the fitting may disconnect.

Great theory...In reality you could pizz black water everywhere

I can’t see it being a problem.

So you are going to dismantle some fittings,possibly cut pipes,fit inserts and new fittings ...All with water on....good luck.

I was going to cut a pipe & cap it.
Now i can continue making my pipe until im ready to remove cap & joing my new piece.

Is it a combi you have..Have you reduced that pressure to zero?Is it outside?
