Zoeller 540-0005 FLEX Series Water-Powered Back-Up 💦 Sump Pump: Reliable and Efficient Emergency Water Removal Solution Review

great product but big buzz. Caution: wastes a lot of water. but overall a great backup solution for those who don't want to mess around with backup pump batteries.

This pump is amazing. Easy to install, drains water well. The float mechanism works great. Now I don't have to worry about losing power again. I bought this to replace a failed Liberty SJ-10 and I am very happy with my purchase.

I hired professionals to do the installation because I'm incredibly inept and didn't want any problems. These words are wonderful. I have an underground concrete "bunker" that is filled with groundwater. Since I had hydroelectric power but no electricity, the solution was to pump out the water.

First, the one they sent me was definitely used. Two o-rings were broken and silicone/sealant was applied in their place, this will affect the functionality of the unit and will determine how you will install it. In my case I was able to fix it myself but for how much it cost it shouldn't even have been a problem. Second, there is no built-in backflow/backflow protection, so you will need to purchase a double check valve with atmospheric valve as it connects directly to your drinking water…
