Aquatec 5852-7E12-J584 1.2 GPM 60 PSI 3/8 inch JG 120V Delivery/Demand Pump with Cord

works well, and pump is quiet.

Would be a 5 star but it is noisy. Increased my r.o. pressure from 20 ish to a 40 to 60 psi working pressure. The pump turns on around 40 and runs till 60 or when fully pressurized.
