Power Shower 15 or 13mm bore??

NiceGuyG

Hi al I am fitting a power shower with some of the pipe work running behind the plasterboard through chiselled brick work.

I need to run the pipe from the hot and cold (22mm outlets) to the power shower. As there are a number of bends I though the following would be ideal;

However it has a bore of 13mm ending with a 15mm copper pipe

I have read the instructions for my shower and it says nothing about the size of the bore. The shower as a push fit 15mm connection so this thing would connect ok.

Could anyone tell me if I am going to notice a pressure drop by running this over 1 metre and into the shower??

And secondly does anyone know where I can find something similar with a larger bore as I was under the impression that the inlet pipe should be at least 15mm.

Thanks

it should be ok. you will need to reduce your 22mm pipe outlet to 15mm for it.
probably a 22-22-15 t-piece?

I really don't like the idea of long flexi's. You need to check the pump and shower manufacturers' instructions on what is expected. If you can use 15mm up to the shower then fine, but don't use a flexi as it will be too narrow and if the shower doesn't work properly you won't have any comeback.

I checked the manual and fitted it according to instructions with flexi pipe.

Thanks for your advice though as it has reassured me!.

I just wondered (as I am looking to do the same thing)...

- What type of flexible pipe did you use ?
- What was the bore size ?
- Are you on a high pressure (combi boiler) system ?
- How long are your flex pipes ?
- Are you happy with the finished system / pressure ?

hope you're not on a water meter - power showers use half as much water again as a bath!!

I used 90cm flexi pipe from screwfix with a 13mm bore on a gravity system. The presure is very good
