    Hi all,

    I just bought a basin wall mounted mixer tap from eBay! It was cheap!

    Any how it came with no flexi able tails. I have my 15 mm copper fixed and the two need fixing together.

    On the basin mixer is two threaded female connection points, they are the same size as the threaded part on a 15mm isolation compression valve ( I tried one I had at hand.)

    What's the best way to connect to the basin mixer, a male to male coupler? What size would it be? Then a flexible tap connector ? If anybody could point me to the correct parts on screwfix? Thanks

    Please post photos of the supply side connectors (on the wall) and the connectors on the tap.

    Will be a BSP thread, most likely 1/2".

    The 4th picture shows the actual back of the item. It's to join up to two 15mm copper hot and cold. I thought of two flexi able hoses with compression fitting on 15mm pipe end and then two male to male couplers?

    What is the size thread on a isolation valve? That is the size thread I need?

    Just had a quick measure the threaded part is roughly 20mm, if you get a 15mm isolation valve and remove one of the compression nuts it will screw in ?

    There's a reason it was cheap.

    Yes they are suitable,use ptfe tape on the male threads and connect the compression side into copper pipe to connect to your existing supply pipes.(try not to use flexible connectors in the wall).

    before doing all that consider having a look at what the actual valve body is made,undo the 6 screws & lift off the cover to access the valve body.Brass valve body is preferred.

    The instructions do not mention any approval for uk use,no wras or similar test house compliance statement. Thats why its best to have it professionally fitted ;).

    £29.99 :D
