Let me start by saying I had high hopes for this pump after struggling with weak shower pressure in my two-story home. The promise of automatic flow detection and a steady 1.5bar boost sounded perfect for my needs.

The installation was trickier than advertised. Like other reviewers, I struggled with the 3/4 male thread connection - it just wouldn't seal properly without excessive force that made me nervous about damaging the unit. After wrestling with it for an hour, I finally got it connected with extra Teflon tape.

When it worked, the pressure boost was noticeable immediately. My shower went from a sad drizzle to a satisfying spray - exactly what I wanted! However, the pump's noise level is no joke. It sounds like a small jet engine in my basement, audible even on the second floor with doors closed.

The biggest issue? The flow switch seems unreliable. Several times I found the pump still running minutes after turning off the water, getting worryingly hot to the touch. This explains some reviewers' reports of early failures or even fire risks - a pump shouldn't run dry like that.

While it solved my pressure problem when functioning properly, the inconsistent performance and noise make me hesitant to fully recommend it. If you try this pump, monitor it closely and consider adding an external timer as backup protection against runaway operation.
