Review on 🚤 BACOENG AC110V Self Priming Water Pressure Diaphragm Pump - 4.5GPM 17L/min 40Psi for Caravan/RV/Boat/Marine: Top-rated Water Pump for Effortless Water Supply by Bam Reeder

It worked very well for a while but for me it was draining water out of my basement for about 5 seconds every few minutes. As it has been raining heavily for the last month or so I spent about 2 weeks like this. I think it either broke at some point or I did something wrong cleaning the filter. The engine is fine, but it doesn't suck. I opened it up, didn't see any dirt or gravel in the valves which could be a problem. I think there is a small sensor or other valve on the front but not sure what it does. I'm not sure what's going on, any help would be appreciated!
