Message-ID: Note: The water leaks from lines 19 and 23 only intermittently. I get the impression that there may be some sort of parasitic turn on of the valves that control those lines when other dump rinse valves are switching on/off as if there is insufficient bypass capacitors on the relays controlling these valves. Nonetheless, these lines and all other similar lines should have teflon/kynar plugs in them.
