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.The same pump without the overflow switch. We'd spend the little extra on the ULS for anything near a finished floor.

Watch out forVIVOHOME publishes no manufacturer spec page we could find; figures are listing claims.One owner's six-month-old UL failed on a furnace in a finished basement and the floor flooded; there was no switch to stop the furnace.
