This is the SeaFlo 45 PSI, 3.3 GPM diaphragm pump I used to pressurize water from my storage drum so I can feed a hot water heater for a shower setup. In my test it built pressure fast and the auto on/off behavior worked when flow demand stopped and started. If you need a simple 120V pump for an RV, boat, cabin, or water transfer project, this one fits the job.
Pros
- +45 PSI pressure rating for feeding fixtures and a hot water heater
- +Auto on/off based on flow demand worked in my test
- +1/2" NPT inlet/outlet and includes adapters and a filter
- +Rubberized feet help reduce vibration when mounted
Cons
- -Power cord is short (about 3 ft), so outlet placement matters
- -My flow shutoff test was improvised (kinked hose), not a perfect valve-based test
