Running a PRV backwards - will I get water?

[jonwestuk]

Silly question, I am installing a new water main and need to run my PRV with the water going against the intended flow temporarily until the old and new mains are switched over.

I am not fussed as to whether the PRV functions, just that I can get water through it in the reverse direction. Can anyone tell me whether it will work?

Thanks,

Jon

It will not work. It only work in one direction.

WHY would anyone fit a valve the wrong way round?

Fit a bypass valve.

If you read the post, the valve is the right way around once the new water main goes live. Temporarily I needed to run it in the wrong direction owing to the design of the plumbing system.

Thanks everyone else, I fitted the temporary solution to a different part of the system. It isnt as elegant, but it works!

A pressure reducing valve is by design a non -return valve that is how it works but one of the top 100 gas engineers will be along in a minute to tell you that if you change the batteries around then it will work
