Connecting to a Cold Water Pipe

S

schmoo27

Hi

I have just bought a compression tee from Screwfix and need assistance on how to connect it to the existing cold wate rpipe.

Do I simply isolate the water, remove the current tap and replace the new compression tee?

Do I need a specialist tool to remove the exisiting tee?

Do I need to solder the new compression tee onto the cold water pipe, or will the olive be fine?

Does the compression tee have to be horizontal for pressure purposes?

The purpose of the new tee is to connect both a dishwasher and washing machine to one cold water supply.

Thanks in advance.

Kevin

switch water supply and tighten valve on pipe, olive will provide seal. use spanner and pliers. make sure pipe is clean in place where valve will be pushed on pipe. hope its a copper and not plastic 😀

Kevin, well done for wanting to have a go! but sometimes these easy looking jobs can be a pain in the rear, if you are not sure just call in a local plumber, better to spend £30.00 than flood kitchen.

Hi Kevin, It sounds like you need to tee's, one for washing machine and one for dishwasher. You will need to cut the cold water feed in order to fit the tee's.

Have you also thought about where the waste for the appliances will go?

To be honest this is a simple job for a plumber so I agree with jts, call a local plumber.

Hi

Firstly, thanks for the replies gents; very much appreciated.

Secondly, the issue of the waste pipes has already been solved. I bought a McAlpine twin hose connector (below) to connect both the dishwasher and washing machine, and it works well (I've added jubliee clips to be extra safe). The issue has been connecting both appliances from the cold water inlet pipe. The first port of call was a plastic 'Y' connector, which seemed OK at first when first connected. However, it seemed that the weight of the flexible pipes were pulling the nut to the copper pipe off centre and water was leaking out. As the appliaces are under a worktop with side panels either end, its impossible to see what happens to the pipes once the applianes are pushed back into place (does that actually make sense? :dizzy2:
).

THanks for all your help; I'll probably wait for a plumber....although I'm itching to do it myself (and to stop the moaning from Mrs Schmoo!).

From your description it would seem you already have a single outlet washing machine tap.

If that is the case then it would be a simple job to isolate the mains water and check that there
is no water when the washing machine tap is open.

Remove the tap and fit the new double outlet one.

The new tap can be fitted in any orientation. Use 2 spanners to remove old and fit new.
Soldering would not be required.

compression tee off your mains supply is fine is there a double check valve ? if not id fit one first then fit the Tee

just had a brain fart
I mite be wrong but what about the draw on the pipe if both was running the same time?
mite be better to a solder Tee the pipe off each side with a check valve then single out let machine valve or just fit two seperat tales to be safe

There is no draw, it's all push.

It is quite easy to connect compression tee with existing cold water pipe but it needs proper attention and systematic work. If you have enough knowledge of plumbing then this is an easy task otherwise call a local plumber to do it well because a little mistake in connection may crate big problem. A local plumber can do it easily; you have not need to call any professional plumber.

Well, problem solved.

Rather than do it myself, I had a plumber friend come and do the work for a bottle of wine... He fitted the cold water inlet T, but with a non-return valve and pressure guage (I think that is what is was called, as the water incoming pressure was originally 4.5 bar but he since reduced this). He just needs to come back with wall brackets to secure it to the wall.

All works fine and Mrs Schmoo is happy with her new dishwasher!!

Thanks again all.

Need to post something (keeping gettingthew message) as I am not a plumber but like to search for answers on the forum rather than 'just post a message' (IE being lazy without at least find if someone else has published the answer already)

To install a compression tee, turn off the water and drain any leftover water. Remove the old fitting with a wrench—no special tools are needed unless it’s soldered, in which case you’ll need a pipe cutter. Clean the pipe ends, then slide the nut and olive onto the pipe and attach the tee, tightening it firmly but not too much. You don’t need to solder; the olive will seal it. The tee can be installed in any position, not just horizontal. Connect your dishwasher and washing machine hoses, turn the water back on, and check for leaks. Use PTFE tape for extra sealing if needed.
