Review on 🚰 Adjustable 12V DC Fresh Water Pump with Pressure Switch - Self Priming Diaphragm Pump for RV Camper, Marine Boat, Lawn Sprayer - 4.5 L/Min 1.2 GPM, 110 PSI - Includes 2 Hose Clamps by Zachary Spaulding

I used it for my fresh water tank in my locked cabin. He did a good job with the water supply for the kitchen sink. The pressure switch worked perfectly, the pump only turned on when the tap was open. However, it was quite noisy and the water flow was weak. I'm sure it was as advertised but not strong enough to splash down the sink. I swapped it for a bigger pump. But I still use it. I am now using it to pump water into a fresh water tank. I get clean, filtered water from the nearest ice machine in 5 gallon jugs. Then I pump it into a 26 gallon fresh water tank with this pump. That works great. Noise and speed are irrelevant. It pumps water up to 8 feet with ease. That's a good pump.
