Are these demountable?

[jrtrrror]

Hi
I'm trying to ascertain whether this type of fitting is easily demountable.
I want to tidy up the pipes that will lead to a vanity unit/basin. One of the pipe, the one on the right is at a very strange angle and no where near vertical. It's probably being pushed away by the short section of pipe running into the 'y' branch above.
Do these demount easily. Or do they leave those 'shark teeth' rings on the pipe? (Sorry, I don't know the proper term and can't be bothered to look it up. 🤣)
I only ask, because the fitting is very close to the floor and not easily accessible if they are difficult to disassemble. I know that speedfit one disassemble very easily.
Thanks

Yes but you have to undo the nut fully and pull it all off once it’s undone eg leaves the grips on the pipe but once removed flip the nut around and then you can push the grab ring off the right way

Hi Shaun. Thanks for the reply.
A. So, if the nut is too close to the floor, it won't unscrew fully, therefore I can't disassemble it?

This then begs a second question. Can this particular brand of coupler be disassembled and then used again?
In more detail, can I remove the nut from the top section of the coupler, remove all the pipe work above it that has loads of unnecessary fitting such as valves and branches etc and then fit a new section of copper pipe back into the top of the coupler and replace the nut?

And which brand is it, do you know?

Thanks again

It might be early hep20

If it’s plastic below you might be able to pull a bit of slack so you can raise it enough you can cut the grab ring (eg just cut a tab / link of the gab ring so u you ou can expand the grab ring and pull off you will need a new push fit fitting)

I wouldby reuse pushfit fittings other than as a temp measure always replace I use jg

Hi Shauncorbs.
I appreciate you taking the time to reply, but I really struggled to understand what you were trying to communicate. I could try and guess, but if I misinterpreted what you are advising incorrectly, I may end up doing something wrong.

The pipe below the coupler is copper and unfortunately it's bound in place with tile adhesive. So will not move and I'm very worried about rupturing any joints beneath the floorboards if I was to attempt.

I think your saying that I CAN NOT...
1. Unscrew the TOP nut of the coupling and retain for re-use.
2. Remove the existing pipe that goes into the TOP of the coupling.
3. Feed original nut onto new pipe.
4. Insert new pipe into the TOP of the existing coupling.
5. Screw nut back onto coupler.

Thanks

You can try but I wouldn’t want to chance the old oring resealing you more than welcome to try but I would keep an eye on it

You would need to move as well the oring grab ring and washer over
