Shower - Connect 15mm compression --> 1" BSP Male

[slimj]

Hi all,

I have installed my bathroom and I was ready to hook up a new shower but it wont fit.

I have one of these built into the wall and tiled over - it is a bar valve fixing kit with 1" BSP threads that was supposed to save me time

The shower my Mrs ended up getting is designed to fit a 15mm pipe through a compression joint rendering my bar valve fixing kit useless. I have also looked at a number of other showers and a lot of these seem to fit 3/4" BSP threads not 1" so the kit I have really is useless.

Here the issue in all its glory...

The only thing I can think of doing at the moment is getting a 1" female to 3/4" male reducing fitting. To do that I will need to grind back the 1" stub a bit which is risky as it might mess the thread up, and then i will be left with 2 x 3/4" males - how can i connect these so they wont leak?

I would really appreciate any advice, I am sure there is a much better way of sorting this which hopefully wont involve ripping everything out.

Cheers,
slim

You put on the kit you designed it to take - the Mrs is allowed to be wrong just once in her life.

Fair comment. If I didn't actually quite like the shower that would have happened.

Plumbing is not my speciality, hence the lack of a constructive response. Hopefully somebody will offer you a suitable solution.

Do you have a link to the fixing kit you used? I've never seen a 1 inch kit before.

3/4" and 1/2" I could understand, but 1" really would be useless - as you said.

 

[slimj]

Yeah, it was linked in my post but this is it....

What is irritating is that SF don't even note on the website the size of it but it is 1".

As you say - useless. I spoke to a few shower manufacturers and they have said 3/4" is common for bars as I said in my post.

Just hoping someone has a suggestion!

According to the Q&A on the SF web-site, they are 3/4".

Most showers are 1/2".

 

[slimj]

I have reported this to SF already as they are 100% 1" not 3/4".

Can you also link to your shower please

Don't forget BSP threads are measured from the inside diameter of the pipe, not the external diameter over the threads. Although the outside diameter of the threads sticking out from the wall may measure approximately 1", they are actually called 3/4" BSP, or G3/4 as noted in the Screwfix installation instructions.

I suspect the only way you are going to sort this out is by taking the tiles off and replacing the fixing plate with a more suitable set up.

A very, very, faint chance, but if the shower is from a well known brand, see if they can supply 3/4BSP fittings in place of the 15mm compression they came with. (The chrome plated elbow bits coming out of the main body).

Yes, there's no way this is a 1" BSP.

The only way to do this without bodging is to start again.

 

[sjmac]

They are 3/4"

 

[EAST61]

They are 3/4"

Yes, we knew that from the start.

 

[slimj]

Cheers for the replies. My bad - agreed these are 3/4".

I suspect the tiles are coming off one way or another. Don't fancy bodging it and even if i can connect everything up, the shower bar will be miles off the wall.

Or, I sack the shower off and get another.

Appreciate the replies though.

Could you use a couple of these and the 15mm compression fittings on the end?.
