Taking Out a Section of Pipe

anotheruser

Here's my layout:

Water comes into the house.
Goes up the wall through the old airing cupboard where there's a red round valve handle.
Pipe then goes into the loft where two tanks used to be.
It then goes down to the (new) combi boiler.

Problem is in the loft, the pipe comes out the floor in the loft by about 30cm, goes across the loft, then back down.

I'd like to cut this pipe shorter so I can put down a loft board.

I guess I can turn the handle in the old airing cupboard, failing that the stop !!!! and just cut the pipe to the height I need on both sides, then join it again and I'm done?

I plan on using the plastic easy fit things.
There's already one at a right angle and I can get another one for the other side as the pipe just bends round the corner to go back down to the boiler at the moment.

Can I somehow unclip the pipe from the existing plastic joiners?
I have a feeling you can push round the edges and it'll free the pipe.

Most types of push-fit pipe have a release or demounting tool, you just need to identify which sort you need.

Are you sure? A "red round valve handle" sounds like a gate valve & will not be on your incoming mains pipe.

Got one of these red handled gate valve in my airing cupboard - It is there to cut off the supply of water to the header tanks in the loft, so nothing unusual there. But to have the pipe looping back down to a combi boiler smacks of a half arsed installation where the plumber couldn't be bothered to reduce the run of pipe.

OP - If you are planning on reducing the length of pipe, check the size currently in place. You might find the old pipe is imperial, and most fittings available are metric. The two are not interchangeable.

Thanks.

The plumber agreed it would loop in the loft, I just didn't realise he means not reducing the pipe. It was much easier that way instead of digging up the ceiling.

Is it just a case of measuring the circumference of the pipe?
It already has a right angle joiner and a straight line one attached so I didn't think to measure.

Although I'm thinking perhaps I can just buy a line of the plastic pipe to make it a little more flexible. Here's a photo.



The larger pipe in the foreground is the main water coming in to the house, but there's clearly nothing I am going to be able to do about that, so it's just the smaller one behind that's taller that I'd be reducing in height.

I have a feeling this is hot water from the boiler going to the kitchen sink downstairs.
If so, I guess I can cut it and it isn't going to drain the boiler or anything?

You have a feeling? You need to know where it comes from & goes to before you start cutting!

Lets hope its not the gas...
