## Description

SEAFLO NEW 12v Water Pressure Diaphragm Pump 4.3 L/min 1.2 GPM 35 PSI - Caravan/rv/boat/marine

Review: Worked for my job - I used this for a camping shower setup. It will pump 1 gallon per minute which was more than I wanted. Built a flow reducer from a piece of rubber and slowed the flow to 1 1/2 gallons per minute. Installed the old style sink accessory spray nozzle in my line to have control of the water which worked perfect. At 35 psi the pump shuts off when you release the handle on the nozzle.
Review: Warranty - Purchased 2 of these pumps in July and Aug 2019. They are used off the grid cabin for about a month during the summer. The pumps are disconnected and every fall and stored in our home. One pump now turns on when you turn on the water. When the water is turned off the flow of water stops but the pumps makes a banging noise and won't turn off. I emailed Seaflo and was told it was a broken pressure switch with instructions to require the pump! What kind of 4 year warranty is that ? I emailed Seaflo and told them no I wasn't rewiring the pump. Haven't got any response. I called Seaflo and voicemail is full. Called desertcart and got sorry contact the manufacturer. Contacted the sellwe and cannot get anyone to answer the phone. The warranty is worthless.
