New kitchen taps with flextails - installation adivce.

Hal1

Hello,
We recently got a set of new taps with the flex tails on the ends. The current setup has about 400mm copper pipes running to the taps from a coupler.

I had removed the copper pipes from the old taps, but can't release the end going to the coupler.

I tried one of those C release tools but no joy. Any tips are greatly appreciated.

You need a crows foot spanner, if there old fashioned taps.

Or a bottle spanner

Might be easier to help you if you could post a picture of this "coupler".

Ok, I've added 3 photo's showing the connections. One of the pipes has a T piece for an outside tap. Both copper pipes are shown here terminating into their coupler's. Below the coupler is a hard plastic type pipe.






The new flex tails and couplers I got for them.


Another thing is the hot water takes ages to drain after I turn it off. There's a combi gas boiler in the house.

It is possible that the copper pipes are 15mm and have been forced into the 1/2" push fit connection, if so, they will be hard to get out.
As you have flexi pipes off the tap I would cut the copper pipes about 2" up from the push fit connection, but not with a hacksaw, with a pipe slice.
Then, connect the flexi to your push fit and then connect onto the copper.
Also, remove the loose nuts and plastic washers from the new push fit, they are not needed.
Edit:
If the copper pipes are 15mm and your new push fit is 1/2" it will need a good effort to push it fully home to make a full connection, otherwise it will leak badly. If its 1/2" pipe it should go on fairly easily.

The copper pipes are 15mm and so is the hard plastic pipe below it. So I assumed the coupler was the same size. Yeah I had planned on leaving about 50mm on the copper pipe for the new coupler I got. I got the removal tool and seen the pipe slice tool but taught sure I'm going to use a hacksaw, but if it's a bad idea I'm going to need to proper tool.

If you use the hacksaw you will leave a sharp edge on the pipe which will tear the O ring in the new fitting.
The pipeslice will leave a clean beveled end which is preferred for push fit connections.

I got one of those pipe cutters today, so will be able to do a nicer cut then a hacksaw would do. Another quick question if you will, is how long should it take to stop the flow of hot water?

I remember on Saturday it took nearly a half hour with all hot taps running, before the pressure dropped. So I taught it must be draining the tank. I didn't see any other stop cock valve in our hotpress, but maybe there's one in the attic...

If you have a Combi Gas Boiler there should be a stop valve under the boiler on the cold water feed. (Make / Model ?)
Turning it off should stop the hot water flowing from the tap almost instantly.
Edit:
Hot Press? Do you still have a Hot Water Cylinder?

There is a yellow handled valve at the boiler which I turned to the off position. There is one inside the hot press for the hot water flow. It still took another 30 minutes for the pressure to ease off.

Then I installed the new fittings, one was faulty so got that changed. It was a bit of a mess with the water pissing everywhere but got it done . Thanks for the help!.
