Hi Robin,

It is much better not to install Wafer Check Valves at all. They cause often waterhammer when there is a pumptrip.The reason for that is that they have a bad dynamic characteristic,

Best Regards,

Hi Paul,

Looks like I must have some how upset our 900 or so members as I had recently posted a query with respect to correct wafer check valve installation and received no replies, or did it go off into cyber space.

Perhaps the query was inappropriate?

Cheers,

Robin
