Thanks for the info. I've requested a copy of AWWA M51 from our library for reference. Will look elsewhere too! This forum is an excellent source of info - I wish I had found it ywears ago!

I am designing a 20" water main. Client specifications require CAV's (they used Valmatic 200 C.2's on a recent 16" project) at high points, but offer no guidance on sizing/spacing. Can anyone point me to a reference? Thanks in advance!
