Connecting 15mm mains water feed to 22mm bath tap

[ChrissyPy]

I could use the attached, screw onto the end of the bath taps, but of my 15mm pipe into the end which then goes into one of those isolating valves I previously showed that I used and then into the rest of the 15mm pipework to get to my original copper. Would that work?

Is 3/4" correct for screwing into the end of the tap thread as mentioned just before the diameter I'm getting?

So i've just measured the outside diameter of the thread of the tap end that i intend on screwing onto and its pretty much an inch, so the 3/4 wouldnt fit?

It will fit.The thread is 3/4 BSP.

ok so i think ive got my plan worked out

Afternoon all, getting closer to completion. So the connectors as shown in the photo that will be screwing onto the underside of the bath taps don't have any washers, first question, do they need any? I will be adding some liquid PTFE to their threads, will this be sufficient or should I source some washers?

tightening these connectors to the bath taps, are they hand tightened only? I ask because there's no room to get an adjustable or much underneath the bath so I presume hand tight is sufficient?

Thank you

You will need more than hand tight and you will need fibre washers toolstation number 30349 will do it.

Purchased, thank you very much.

Can you suggest a tool that would make tightening them easier which such restricted access?

or go one better with an end feed 15mm to ¾" tap connector... don't forget the service valve of course

Yes, solid copper all the way. I really dislike all the rubber lined flexibles seen around today. I wonder how long the rubber lasts when constantly subjected to fluctuating pressures and temperatures. A good length of copper tube and a well set up floor-stand bender in the right hands make for an A1 installation

A monument basin wrench is the go-to tool, but a tad expensive for an occasional use. Screwfix sell a single ended one for a tenner.

If that link times-out, then search Screwfix product No 868XR

Brilliant, I was just at Toolstation picking the washers up, went next door to return all the bits I didn't need and saw your message so I ordered it then and there, thank you.

Bought a pretty decent one a few years ago from B&Q when I was fitting my bath. Used it once, I hadn’t removed the tag from it so I took it back for a refund.
