The Aquatec PSW-240 tank shutoff (TSO) switch for the Aquatec booster pumps
used in RO systems with a tank. This switch connects to your water line on
your RO system and shuts off the pump when the tank pressure exceeds 40 PSI
or the ESO (if applicable) turns off. This prevents your pump from running
unnecessarily. The TSO features 1/4″ quick connect fittings and comes
preset in “Normally Closed” position. The TSO does not require the ESO and
can be used on it’s own.
