How do I remove plastic compression coupling to access external waste pipe?

Looks like a proper job, maybe a rodding point might have been a good idea

Rodding points WILL be needed in around a year and a half maybe two years time subject to useage unless it s the camera lens distorting angles.

Also guess he had the attitude that reading the instructions was for dummies.
2nd photo, top left corner, is that white bit a pipe at an angle or an open window and that notch looks deep.

Unless your loft floor is out of level it doesn't look like the pipe has a fall on it? I don't think you are supposed to use tight 90 degree bends either, 2 45's are usually specified in the manual.

Luckily there is a slight angle to our house in the direction of the soil pipe. I did ask about the need for more fall, but installer said pump in our saniflo is so powerful so not an issue. After flushing I can hear water washing around in the loft pipes for around 30 secs before it goes through to external run and into main soil pipe, so working fine now, though I wonder over time how things will pan if water pressure isn’t that high as the run is so long and horizontal.

on ridding points, where is the best place to install and is it a straightforward job?

Rodding points can go on every bend, install a 't' with the blind part a threaded removable stop end. centralheatking

Too many fittings there. 😱

Putting rodding T on every bend is an overkill.

Anything over a few seconds is wrong.

How would you do it?
