3/4" bsp to 15mm pipe

[marlb]

Hi all,
I have just bought a new shower and found that the connection to the shower valve is 3/4 inch bsp. I am running the shower off a combi boiler on 15mm pipe. I cannot find a 15mm to 1/3 inch bsp adaptor anywhere. I have searched on the net but can only find 1/2 inch to 15mm or 3/4 inch to 22 mm . I do not want to start using reducers and 22mm pipe. I just want a nice straight forward 3/4 inch bsp to 15mm adaptor.

Can anyone help???

They are pretty common, just ask at your local plumbers merchant for a 15mm x 3/4" Male Iron (M.I) or Female Iron (F.I), depending on your connection, and they should be able to help you.

This should be similar to what you are after and if you read down it will show you the sizes that you can get.

I have bought some 3/4inch to 15mm compression adaptors but the 3/4 inch male threaded end seems to be a little loose when i connect it to the shower valve. I have put plenty of ptfe tape on but I am sure it is not the correct fitting. What does BSP stand for. The adaptors I have bought do not mention BSP so think I may have the wrong ones.

British Standard Pipe(thread)

Alot of people seem to keep saying this, I very rarely do showers but maybe one of the others on here may be able to educate the OP and myself.

Is this normally a problem that you get with these (because i've never come across it) or is it, as i am suspecting, that it is a problem with some cheaper showers etc that can be bought via ebay etc and the machining isn't great on them?

Correct - these do feel a bit loose, worryingly so given that they are likely to be embedded in walls without subsequent access. Just have to keep on with PTFE - not had one leak yet.

You'll also find some bsp male threads are tapered (bspt) and some not.
If the seal is being made by the thread itself then tapered is best, if seal is made by end face and washer then parrellel is needed.

So as aposed to BSP they work on CBSP (Chinese British Standard Pipe)!!

Thanks for the responses. So swidders, are you saying that I have the right adaptor but need to use more Tape to seal the thread?

I want to plumb it in tomorrow.

cheers

That seems to be the brunt of it marlb.

Where was the shower from?

Cheers Guys,

I have now plumbed it all in and there are no leaks.
I bought the shower from Bath Store. The problem I have now is setting the thermostat. I have set it at the hottest point but when you switch between max (hot) and max (cold) the temp hardly moves. The only way around this is to set the thermostat at temp that I always take a shower. My last shower was a swaddling and the range was fantastic from Max(hot) to Max (cold). Moral of the story is if you pay peanuts you get rubbish.

What happens if you set it some way down from maximum? Do you get a variation in temperature then?
