Copper Tap Connector will not fit tap

[sail&fish]

Decided to plumb copper to my bath valves rather than flexible hoses as this is a job I only want to do once. I tried 3 local shops for some 15mm x 3/4" solder ring tap connectors and eventually found some.

Unfortunately the hole in the bottom of the bath valve has a smaller diameter (ID 17.1mm) than the end of the fitting (OD 19mm);the valve outlet on the side is even smaller (ID 15.2mm). I have a photo but the site will not allow me to insert it.

So my question is:

• Can I cut/file off that bit of the connector, that would insert into the fitting, flush with the ring onto which the nut tightens or will this weaken the ring too much?
• Am I likely to be able to locate a copper tap fitting with a narrower end?
• If I were to use a 3/4 x 15 flexible copper stick am I likely to have the same problem?

Try a different make or Maybe file the tap out

3/4 female iron to 15mm copper would get over that issue

thats because the tap end is designed for a flexi connector, it has a flat face for the rubber washer to work properly. New taps required dont be messing with trying to make a comp fitting work with that or you'll end up crying.

Whenever I come across that problem, I just cut the raised bit off the tap connector with a hacksaw. Then finish with a file and emery cloth. Bit of paste on the washer and Alls good.

plus one for the female iron to copper put a flat green washer in it and a bit of tape or 55 on the thread

Got to be better than a flexi! :45:

So workable options are the 3/4 female iron, cutting the raised bit off or using a flexi for which the tap appears to be designed for.

I know flexi is easy and easy is seldom best but what are the downsides of cutting the raised bit off.

Strange how my in-laws new build house is all plastic and flexi yet I feel I should copper it all the way

So workable options are the 3/4 female iron ................do it right,

what are the downsides of cutting the raised bit off................watch it leak

I feel I should copper it all the way and watch it last for years n years

+2. By far the best way.

Unfortunately the thread on the female irons is too long for the valve so the washer will not seat. It looks like I either use flexis or find some new valves to feed the overflow filler that will take a copper connection.
