Thanks Kevin for the response and diagram..very helpful..In theory, if they are on an equalization loop they shouldn't need their own valves as pressure should be the same to each jet. For individual control you would either need home runs for each jet to the return pad, or a valve tee'd off of a supply line near each valve. If you have individual valves for each jet from the equipment pad you shouldn't need an equalization loop though. I attached a pic of how I plumbed mine. I'm definitely not an expert by any means so take this with a grain of salt.
