BAZPO 12V Submersible Water Pump - German Made (2.5GPM/18ft.) | Portable RV Water Pump - Works with Electric Switch in 12V Faucets | 12 Volt Small Water Transfer Pump for Camper (Filter & Valve)

Easy to install and quiet

Made a portable shower with it. Pumps just the right amount of water for cleaning off after a day at the beach. I run it off of the battery I use in my kayak. Can also plug it into any 12VDC cigarette lighter outlet so my wife can use it in her car when she takes the grandson to the beach. I carry 5 gallons of water with me and it's enough to rinse off up to 3 people as long as you shut it off while you lather up.Manufacturer says you can use it 15 minutes continuously and then you need to give it a rest for 15 minutes. Never had to use it that long. Wire diagram doesn't come packed with the pump. Had to go back to the description in Amazon to get the correct wire color coding so I didn't hook it up backwards. The pump wires will have to be extended if you intend to use power from a vehicle. Add a cigarette lighter adapter or battery clips. I used the Sparking 12V cigarette lighter power adapter from Amazon. It comes with a built in fuse as added protection and it also has a red LED light that comes on when it is plugged in to let you know power is good.

Versatile n small

Very low flowPumps about 7ft vertical/ headNot happy

I purchased this pump last month and received it without any problems, but there was no check-valve (or back-flow preventer valve) inside the package. Is there somewhere I can purchase this? I have about 6 feet of hose head height for the pump to pump water vertically, so I would prefer to have the check-valve and prevent the backflow at shut down. Thank you.Edit: I contacted the seller and he actually shipped me out a check valve at no additional charge! Very nice of him.
