Review on Powerful SEAFLO Water Pressure Pump: 12v 3.0 GPM & 45 PSI by Ryan Person

Adapter and filter included. Bought 2 pumps a DOA. Non-standard threads. If you don't want to hook up with the included spikes, be prepared to be rigged by a jury. The threading is almost, but not quite, 1/2" standard pipe threads. I've spent a lot of time and fuel trying to find adapters and fittings that work. I wish I'd returned them both on day one. The one that worked Pump is strong and amazingly quiet.
