Review on 🚰 Amarine Made 12V Water Pressure Diaphragm Pump - Self Priming Pump 4.3L/min 1.1 GPM 35 PSI - RV Water Pump for Caravan, Boat, Marine, and Agricultural Uses by Jason Graham

I decided to try this on a recently installed battery watering system and it's so quick I was amazed. It sucked up nearly half a gallon of distilled water in a matter of seconds. basically zero pressure at startup. I don't need 30 or 35psi for this application so hopefully the pressure switch can be set to 5psi. Of course if you use it at full compression you will need a clamp on the exhaust port. Well, as for the half-gallon, it was a new installation for 48 L-16 cells. 16 S-605 Rolls batteries. I end up putting it on a timer. a few minutes once a month. The small pump easily feeds two Flow-Rite BG-U48V-1G sets. I didn't see an arrow showing the direction of the river. when blowing bubbles. turn the pipe over; 5 Stars . For your health!
