Small Pump With Level Sensor 110V Automatic Submersible Water Pump Mini HVAC Condensate Pump For Dehumidifier,Air Conditioner, Ice Maker, Furnace,Air Cooler,Auto Shut Off,PM01

seems to work well. I was a bit concerned about it. I placed it in some a wading pool that catches rainwater for some plants and find it keeps the water at the level I need it by placing it on a container the depth I need the water to be..

hard working little pump. 5 feet is right....buy bigger one if you need to go distance. will not pump thru a check valve

The pump is small and does its job well for draining condensate automatically, especially with the built-in level sensor. It took a little adjustment to get everything positioned correctly, but once set up, it runs reliably.

It runs, it pumps when the sensor is touched, it turns off... Then the water left in the tube that didn't get pumped out flows back into the container, triggering the sensor and the pump to start running again. There should be a backflow valve included because the pump never actually turns off. The 12 inches of water in the outflow pipe just goes right back into the container when it stops.

The sensor does what it is supposed to do and starts the pump when the water level is about half way up the pump sides. The problem is (at least on mine) there is a vent hole in the top of the pump--apparently to allow rising water level to push the air out of the pump impeller so it will prime and pump. But the pump also sucks air down thru the vent hole as soon as it starts pumping. So it is pumping both air and water which reduces the volume of water pumped and reduces the height the pump will pump. If you put your finger over the hole while pumping, the air in the line goes away, the volume increases and the the pumping height goes up. Also when the pump is fully submerged the vent hole would be covered and it would not suck air, but since the sensor is below the top of the pump, the water level will always drop below the top vent and it will end up sucking air. It needs a check valve that will close the vent when the pump starts to suck. I'm wondering if I can put a little flap of thin rubber over the hole that will allow the air to vent when the water rises but close when the pump starts pumping water. The pump has possibilities but it was like they quit working on the design before it was finished. The instructions if I unterstand the meaning says the outlet needs to be higher than the pump to keep it primed but it doesn't seem to make any difference whether it's higher or lower than the pump. Maybe the water draining back into the pump is supposed to raise the water level enough in the reservoir to keep the pump impeller covered? Doesn't matter as long as the top vent is open it still sucks in air. The pump as designed is self defeating. Also further investigation reveals the pump leaks substantial water out at the seam between the middle and lower sections

Pump works great!!

Pumps all the water out of the dehumidifier and has been working great for a long time. The problem with it is that once it's done pumping the water down it never shuts off, that might be the lack of a check valve, I'm not sure. When this one stops working I'll probably look to get something different.

Placed this pump in a sump bucket in the crawl space under the house. It works great so far. It's above any debris so should pump clear water.
