Let me start by saying this pump is a beast! I've been using the TDRRICH Water Pressure Booster Pump for my RV and garden irrigation, and it's transformed my water pressure from 'meh' to 'wow'. The automatic start-stop feature is genius - no more fiddling with switches when I turn the faucet on/off.

The 5.5GPM flow rate is perfect for my needs. When I'm washing my boat or running the sprinklers, the 75PSI pressure makes everything more efficient. Installation was straightforward with the included fittings, though I did need an adapter for my specific hose setup (not the pump's fault).

What really impressed me was how quiet it runs compared to other diaphragm pumps I've used. My neighbors haven't complained once during early morning garden watering sessions!

However, there are some caveats. The plastic threads feel a bit cheap - I nearly stripped them when connecting to metal fittings. Also, while mine has been running strong for 3 months now, some users report reliability issues after extended use. The pressure switch can be finicky occasionally.

For mobile applications like car detailing or marine use, this pump shines. It's lightweight enough to move around but powerful enough to handle serious water transfer jobs. Just remember - fresh water only! Overall, at this price point, it's hard to find better performance.
