Water Main Valve Requiments

Depends what your water provided requires. 
 

I always put a drain valve and a full bore lever valve past the stop valve as I don’t trust gate valves. 
 

NRVs can be restrictive - if you’re up past 7 or 8 bar then a PRedV is a reasonably

good idea before you get to the control set for the UVC

I put a lever valve - much easier to turn . Outside I also have a non return valve as water company insisted on one as we were going to have rainwater harvesting. That plan was binned though as ROI was around a billion years

Did you attempt to calculate ROI and how?  Was this for house or just the garden?

 

 

House. Cant remember exact ROI. But cost of a proper system and pump; savings were minimal was the real issue.

Double check valve required in Scotland by Scottish water, which must be an admission the single check valve incorporated into the boundary box that they supply does not work :ph34r:

Given that mine is currently leaking I think you may well be correct.
