    Liquidator adds Cl even when control valve is off?

    I was wondering anyone know if when the control valve for the LQ is off and the flowmeter is showing no flow at all, does the LQ still add Cl into the pool?

    You might get a small amount if the pump is shut off and you don't have check valves on both sides, but not enough to measure.

    Hi John,

    Thanks for the quick reply, I have both check valves on each side and did modify it to the 3/8" line too.

    It must be because it is cooler here still (in the 60's and 75 is few and far between this year so far, its usually close to 80 this time of year, so much for global warming!LOL), and I have my solar cover on almost all the time. Must be it is the combination of the cooler temps and the cover. It just means the Cl I bought (6 cases) will last longer and maybe even into next year!

    Thanks

    I noticed mine measures higher than usual (flow set at 1) and pump runs 8hrs/day. I attribute it to the colder weather (no 80's at all) and zero use.
    15,500 gal, inground gunite pool with 7 ft spa, 2 speed pump 2hp/.33hp, 3/4 hp booster pump, Intermatic P1353 timer, AutoPilot SC-48, Sand filter with ZeoBest, Heater, that I never use . . .

    Check your check valves. Hasa's may come DOA new from the box or get biderectional with time. Mine did. I advise you to check rabbit's 3/8" line conversion post and to order the check valves from US Plastic.
    If the control valve is indeed closed and gives 0 flow and the check valves work as they should, I don't see how the LQ can supply FC to the system. Zero feed means zero gain.
    This is my ticket for Heaven (when all's working..) :

    Yes I did convert everything over to 3/8 line last year.

    Yes your right zero is zero but I thought maybe a little got by.
