Review on πŸ”§ Merrill Pressure Air Pump: Adjustable Differential Test, Measure & Inspect Pressure & Vacuum Effortlessly by Sean Maples

Revainrating 5 out of 5

Your main pressure control but low pressure range.

I bought this for use on a rainwater booster pump designed solely for sprinkler service but be aware that the 40psi maximum pressure rating is quite low for a typical plumbing system, especially if you have to start something uphill. My fountain is currently running at 60psi and even then I'm not getting much flow from the hoses etc.

Pros
  • Pressure and Vacuum
Cons
  • Very expensive
