Basement Watchdog SI-50V Reviews & Ratings

Great Pump For Price
By Andrew B
Massachusetts
Purchased 12/12/2024 |
Review Posted 01/03/2025
After many years, my old pump finally died. When I asked the installer to replace it they wanted $1000 for just the pump. This was the exact same pump for a 10th of the price. Be very careful to ensure the bracket for the float is perfectly level. I had my float get stuck and cooked the pump the first week due to misalignment

Basement Sump pump

Review Posted 05/03/2022
I am very pleased with the pump being shipped as requested as my old pump and I had to check several times a day to juggle it to pump. Without this pump my basement would flood so I also purchased water monitor. I am happy happy.

Cast Iron Propeller

Review Posted 05/26/2020
I live in an area with lots of algues. I have been using BW-1050 for years. The motor frequently broke. I was told by the manufacturer because of the algue deposit, they would not cover the BW-1050 under warranty. They recommended the SI-50V model. So far so good.

Working Well

Review Posted 02/11/2020
Bought this pump because the old pump, which was bought at a big box store, was cast aluminum, and the water softener effluent corroded it into a solid block. The cast iron should be more durable in that environment. So far, so good.
