[Plumbing] Replacing mixer taps in kitchen

[mudcow007]

Our cold water tap on our mixer (seperate taps on one unit) has broken.

So just bought a new mixer tap from screwfix, went to fit it an the fittings look nothing alike?

old taps, go straight to copper pipe?

new taps go via flexi pipe?

what do's?

[mudcow007]

after looking at my own photo, if i was to cut the pipes then fit a few of these on

then i could screw the flexi's to these couldnt i?

i can see cutting the pipes to be a bit of an issue though

Those two copper doofurs will unscrew from your existing mixer. (The Hex will unscrew from the underside of the mixer body.)

You need to buy two 15mm fittings c/w Nuts and Olives.

Cut the two doofers off above where they have been sweated onto the hot/cold supply.

Wire wool the top 20mm of the supply.

Fit your straight 15mm fitting over the cleaned end.

Nip the nut tight onto the fitting. (You do not need to go mental the brass olive is soft.)

Remove the nut and olive from the other end of your straight fitting.

Install your flex hose nut over the fitting.


Edit:
Buy a wee pipe cutter. Cheap as chips.

Edit II

You have to turn your water off at the mains and isolate your hot water supply at the hot cylinder or boiler.

You will then have to open all your taps and let the water drain.
It could take ten minutes to drain down.


Then you may have to go here to get your hot running again.

You don't need to turn the water off and drain it all.

Using some freeze spray on the pipes is much easier and the excitement of getting it all done before the ice melts is much more adrenaline filled then the boring option of turning the water off.

Cut the pipes.

Put on these

Then fit flex pipes to those and screw the flex pipes to the tap. (Note you may have screw the pipes to the tap first as depending on the tap fitment only the valve end spins freely.)

Sack off Screwfix and go to your local plumbing merchant, you can walk in there with the tap tell them what you want to and they will get the bits, and you can check in in the shop to see how it all fits together and ensure you have the right bits. I bet it will be noticeably cheaper too.

OP, please can you provide the Screwfix link for your new tap and preferably a photo of its connections?

slight update

hit a snag, the pipes that come from the bottom of the new taps are way to long to under my sink. looking at the picture i posted the legs would easily go past the soldered "T junction" at the bottom of the picture

then i would need to fit isolator valves aswell as the flexis to the supplier. how much room to peeps have under their sinks?!

Once you've had to waste time on plumbing where someone else decided to save a little bit of time and money by not fitting isolator valves, you'll appreciate how useful they are.

On a similar topic... push fittings! Just don't!!
