Review on 💧 WaterGuard: High or Low Water Alarm - Ultimate Protection for Your Water Levels by Jack Boldt

I purchased this product and the alarm went off about a month after installation. Checked, the sewer level is normal. Drop the block and he's still alarmed. So I just left it disabled and didn't use it. About a year later I decided to plug it in and try again. When I plugged it in, the alarm went off again for no reason and didn't stop until you unplugged it or plugged it back in. A piece of junk. Wouldn't buy.
