The best solution for this?

Basically we have too high a water pressure 4-5 bar daytime and need to get a pressure reducer fitted inline before the water softener.
I want to fit this on the leg after the 22mm ball valve going into the softener as this is the least disruptive and does the job.
One of these

Now what other bits do I need to connect this. Just been ages since I did this but gut feeling is 22tap to compression then 22mm copper then compression to BSP 22mm male tap?
Pictures attached, it’s the lower horizontal pipe with ball valve I am on about.
Many thanks!

Yes.
When you buy the PRV all you will need extra is about 2" of 22mm copper, the other fittings can be re-used.

Thanks a lot much appreciated, I will need to get 2m of copper at screwfix as that’s the smallest they sell oh well. You have saved me buying unnecessary bits, thanks!!

If you do it that way then you will not be reducing pressure to the unsoftened draw off before the softener nor the supply when bypass is on.

Thanks, the draw off feeds the drinking water tap and garden tap only. The whole 22mm softened water runs to the loft where the installer who did the work has fitted a PRV and then split the water into cold softened run and to boiler/unvented all capped to 3bar. These two then feed the entire house. So basically trying to protect the water softener due to night time pressure when it does regeneration at 2am. Hopefully I am thinking straight! Thanks for the well spotted advice!

If it were me, I'd protect the incoming main, before anything else... In the event of a failure of a downstream component, you are protected from 4+bar untethered.

Hi, there is another prv upstream! Thanks.
This is all done now.
Thanks for everyone’s help. The only annoying thing is the pressure gauge faces 90degrees from view and no way to adjust it! Washer? Don’t know best way to get it face the correct way.
