Review on 🔌 Dual Pump Installation Kit by PumpSpy by Jeff Wyble

This saved me a lot of time. I installed a Zoeller M53 drain pump in my sump with a Pump Spy PS1000 system using this dual pump installation kit and it works like a charm. I drilled a drain hole in the check valve threads just above the Zoeller pump but below the check valve. Everything fit perfectly in the hole under the lid. Check valves are so quiet that we don't hear any noise at all. I measured the diameter of the entire setup with both pumps and it's about 13 inches. It fits easily in my cesspool.
