Bath Taps Installation Help Please

[Turtle Shed]

Hello all.

Some help with my new bath taps please. These (along with everything else for my new ensuite) came from a local bathroom supplier/plumbers merchants. (I can ask them for assistance on Monday, they're a good and reputable company) but still would like a PH opinion.

Three questions: Firstly, as you can see, the valves have 22mm fixings, and that's fine, as I have 22mm on both hot and cold coming in to the ensuite. However, the spout is only 15mm. Should I have a spout with a 22mm connection? Surely the 15mm negates and advantage of 22mm, or it the case that 22mm for as far as possible and then down to 15mm is fine?

Secondly, what items/connections do I need to go into and out of the valves and on to the spout please? I get that I'll be going into a T-Piece (presumably with 2x22m fittings and a 15mm 'output' which then connects to the spout, but I'm unsure about what goes into the threads on either side of the valves.

Finally, there appears to be no fixing as such for the spout. My assumption is that the T-piece will be what supports it, and given that T-piece will be between the two valves which will be solidly fixed to a batten I guess that's OK. (I have those interlocking wall panels to fit through, but they won't provide any real support, just a bit of protection from the spout being knocked).

Thanks for any help.

Take what you have to your nearest real plumbing merchants, not a b&q type place , a spit and sawdust builders - plumbers trade place , tell them what your doing and they’ll sort it out for you .

To be honest it looks like a box or two is missing from the delivery.

Do you have a link to the item online and a catalogue picture to show what is supplied? Are there any installation instructions?

[Turtle Shed]

I think if nobody minds I'll pause this for now and chat with the plumbers' merchants on Monday. Just wondered about a bit of PH advice on a Saturday night, but will see what they say.

Cheers all anyway.

BTW they are not 22mm and 15mm, they will be 3/4" thread and 1/2" thread. Male or female.

The spout thread looks like it is 3/4" too from your picture.

Are there no shrouds to go over the feeds and the spout ? Otherwise youre going to have to be incredibly precise cutting tiles or whatever will be covering the wall
You need 2 of 3/4 inch male iron to 22mm compression for the hot and cold inlets , then if there is nothing else in the box youll have to connect the hot and cold outets to the spout using 3/4 male iron to 15 or 22mm connectors a 15 or 22mm tee and a 1/2 or 3/4 inch female iron to the required size of copper . I would use a wall plate elbow to give the spout rigidity.
This is fairly advanced diy with a lot to consider , positions , depths , they normally come as a kit to make installation more straightforward

Is it just me or is there a bit missing that goes between the taps/valves & into which the spout part is screwed?

Hello all.

As there have been a couple of comments as quick response from me, and admisison that yes, all the threads are 3/4". My mistake, sorry.

There are shrouds to go over everything, so the install will look neat, and there are also some plastic 'cones' which temporarily fit over the valves to allow you to set them at the correct depth from the wall.

Thanks to miroku1 for specifying the parts, and I will pop back to the plumbers merchants tomorrow and buy what's needed. This I think answers Mr Pointy's question.

It is a bit complicated I agree, but in my favour is the fact that this is all being fitted into an interlocking wall board that I am yet to fit. So I can cut the board to size, then fit the plumbing, and leave me a simple 2x22mm push fit onto the incoming copper (or I might go compression and copper), the pipes are very accessible.

Bath then goes in to position, with the only connection on that being straight through to the outside wall.

Cheers all.

I’ve skim read, and apologies if I’ve got this wrong but looks like you are facing the same situation I was last year…
Taps and spout and no obvious way to make the thru wall fitting work if you couldn’t access the rear.

My solution…






Final result…




I’ll try find a link for the missing bit I had to source in the middle + thread extender to make it work!

Found it…
