Wow, the meter can be serviced from the side, so it is better? How often do you have to repair or replace the meter on a Fleck or Clack? Every 10-20 years if that? Testing the Fleck meter is much simpler to troubleshoot since its cord is not integrated. Wouldnt that make it better?
We could do this all day, but dont you ever get tired of it?
Upflow regeneration, yaya, I have 2 customers that bother with that, and they only do it for marketing reasons, not for actual function or efficiencies.
The 7000 can be used on systems down to 8" without a problem, and up to 24" in diameter for both softener of backwashing systems. The 7000 can also accomodate external relays, internal relays, microswitching, and even has a PLC light version available in the NXT and XTR board configrations with flow controlled outputs, and extensive programming capabilities that is not available on the Clack. that being said, so what.
Both clack WS1 and 7000 are excellent. I have already shown that the 7000 is more compact than the old 5600 electromechanical or the 2510 electromechanical valves. i never see you complain about their size.
