Incredibly Quiet and Powerful
5 Stars
Incredibly Quiet and Powerful
WOW IS THIS PUMP QUIET! Replaced a 1/2HP Campbell Hausfeld sump where the switch had started to fail and not always trigger when the float was up. Thankfully we had a battery backup sump in place as it took over while we were out, otherwise we would have had a flooded basement! First things first, if you're reading this and on the fence about a backup system, get one - it will save your basement from flooding, probably more than once.Back to this sump pump, the whole reason for this review, it is QUIET. The 1/2 HP we replaced could be heard running from the main floor, wish I would have put a db meter on it to see how loud it was. This Wayne pump runs at only 60db! For comparison, normal close quarters conversation is around 60db. Uploaded a couple screenshots from Sound Meter, which was used in my phone at a distance of 3ft from the covered (not sealed) pit. With water running into a near-full pit, the db sits around 38db. When the pump runs, it jumps up to around 60db, which by my ears might more be contributed to the sound of water rushing through the PVC pipe, and not necessarily all from the sump pump. Once the pump shuts off, the noise level settles in around 42db as the trickling noise and splashing of water is louder in a near-empty pit that a near-full one.Helps that a few years back, we also added the Quiet Check Valve, which prevents the load "slam" you hear from water pushing back down against the valve after the pump shuts off. Now, unless you're right outside the utility room door, or in the room with the pump, you can't tell it's running.Well worth the investment. The switch, the most prone part to fail, can be had on Amazon for about $20 it appears. I hope to get 5+ years out of this pump before a switch failure, then for a simple $20 fix, get another 3-5 years out of it before worrying about a full replacement again.
