Let me tell you, this little pump has been a game-changer for my weak shower pressure - but it's not without its quirks. The first surprise? Those garden hose threads that don't match standard plumbing fittings. I spent an extra hour at Home Depot figuring out adapters, but once connected properly with some thread sealant, no leaks!

The auto on/off feature works like magic - it kicks in when I turn on the shower and shuts off automatically. My morning showers now have actual water pressure instead of that sad drizzle I used to endure. However, my neighbors probably think I'm running a small factory in my basement - this thing is LOUD even with rubber mounting pads.

One pro tip: install a check valve! Without one, the pump kept cycling on and off constantly. After adding the valve, it behaves much better. While it does boost pressure as promised (my tankless water heater performs noticeably better), the temperature fluctuations some reviewers mentioned are real - I solved this by installing it before the water heater rather than after.
