Our scoreNot reviewed yetSCORE7.3 / 10
Our takeOur default for a first flare install: a two-stage 5 CFM pump listed as sparkless for A2L refrigerants like R-454B and R-32. Pair it with a micron gauge, because the pump alone can't show you 500 microns.Our default for a furnace, air handler or dehumidifier lifting water up to about 10 ft, with the overflow switch the bare UL lacks. Plan on motor noise and a check valve that needs cleaning.

Watch out forVIVOHOME publishes no manufacturer spec page we could find; figures are listing claims.The 15 in the name is shut-off head, not working lift; the manual's 75% rule puts planning lift near 11 ft. Remove the cardboard insert or the pump will overflow. Warranty is 12 months from purchase.
