I have a Fleck 5810 valve plumbed upstream from (before) a garage booster pump with a flow control valve. Whenever my 5810 regenerates the booster pump turns on. The booster pump should only turn on when there is water flowing through the pump flow control switch to the garage plumped several meters downstream from the 5810. I am guessing the 5810 regeneration creates some change in downstream plumping pressure that trips the pump flow control switch. Does this seem reasonable? Would a check valve before the flow control switch be a possible solution or would you instead consider finding a less sensitive flow control switch? Thank you for any advice. David
