Taking Out A 28mm Tee to Replace With Connector On Pipe With No PLAY

How do i replace a 28mm tee with a connector when the pipes are rigid and fixed on both sides? I.E.. I can't pull the pipe together to get them into a push fit connector.

Do I replace a section with plastic pipe that will bend? Do I put two connectors in and a fresh piece of pipe and just work the new angles? Is there a special fitting for this situation?

Thank you!

What's making them rigid?

You would need 2x slip fittings to allow you to put the pipe in place move slip fitting to correct place then solder them.

You need to cut the tee out and use "slip couplings" but they are only available in copper . Speedfit may make somthing that may do , not sure .

Thank you! Will reseach cost of slip couplings.

Depending on what type of 28mm solder couplers you have you may be able to file out the little indentation stop and make slip couplers out of the couplers.

I would prefer pushfit fittings as soldering onto old pipe with water in seems problematic.. Imagine steam and poor solder.

 

[s3anreilly]

Water dribbles in the bottom of the cut pipe..

Lots of soldered joints around

If its imperial i.e. 1" copper rather than 28mm pushfit fitting will not seal properly & may require special fittings along with the slip fittings

you can get compression slip couplings

Isnt it best not to put compression under a floor and above a ceiling?

 

[moonlight]

One straight coupling a slip and and a reduced tee 28x28x15. Just make sure you haven't got imperial pipework.
If you have imperial you will need adaptors for 1" pipe then onto 28mm etc.

Dont use compression under floor or ceilings asking for trouble

 

[ShaunCorbs]

That's 28mm not 1" so you should be fine

And which t would you like to remove ?

ideally soldered but as you cant use them i would rather trust a compression fitting
over a pushfit.

Both.. Theyre cold and hot water feeds rising up in 15mm

I can't see any real problem using soldered fittings there! I always manage.
And slip fittings if you have no movement.
Somebody has used all copper pipe with soldered fittings and you are now going to use inferior push fit, just because you think it too difficult IMO.
Get an experienced plumber who is used to working with soldered fittings to do it for you. Have it all drained for the plumber and that will save most of his/her time for the job. If you are sure there isn't going to be enough movement, then buy 4 slip fittings beforehand, as highly unlikely a plumber will carry them in 28mm. Sometimes it is best and cheaper to call in a pro.
Most water that doesn't drain from the pipes can be removed other methods easily.

How would you remove any water dribbling down the pipe?

Can't you just cap the 15mm ?

And a piece of silicon tube and a towel

Nope as the pipe has to be taken below the boards.

If they are heating system pipes I would drain system well in advance so that most of the water will have drained away. If possible drain it a day or two before you do the work. Then just got to get rid of any water lying in pipes and in any dips near where you are soldering, like the pipe bent below and up into a tee. Usually blowing through pipes, or using a vetvac or a small bore piece of plastic tubing to syphon some water out will do the trick.

There looks to be just enough length of 15mm from the branch of the tee to put a brass stopend on. Pity about the poor soldering with the solder running down it though, but it could be removed

Good advice thank you

Great point.. Will cap that one at that point.

Hello one option you have is take out 28 mm tee if its copper you are fine get 2 28 mm copper connectors and with a round file and half round file use your files to file out the stop in the fittings this way it will push up on pipe then cut the length of 28mm pipe you need make sure you thin the ends of this pipe with solder mark were the stop is on the pipe from the solder connector and solder same with PVC same thing Dave01
