Review on 💧 Efficient Dual Flow Water Pump - J & C Water Systems R3700CW in Colonial White by Steven Brouillard

Fits just right to replace the unit I took out which was nice. I've noticed that the hand pump loses primer very quickly, but pumps well after you've pumped it to prime several times. I then hooked it up to pressurized water and the manufacturing flaws were all too apparent. I had a couple of accidental holes in the plastic that leaked water when the pressurized water was turned on. This explains why the hand pump loses suction power within about thirty seconds. I connected the unit after the pressure regulator and it was hooked up to my home water system which is on a well pump so only about 40psi will work anyway. I hope this is easily guaranteed and will update my review. Update: downgraded to 1 star. I got my replacement part thanks to Revain's wonderful exchange policy and the part has not leaked and has worked fine with pressurized water but it has not manually pumped water from the storage tank no matter how much I pumped. I even turned off the pressure side (which is NOT a good thing) and it still wouldn't pull from the tank. So I'll cut my losses, throw them in the trash and get something else.
