Powerful Pump for Precision Testing

This Industrial and Scientific pressure air pump is a game-changer. It delivers consistent pressure and vacuum readings for precise testing and measurement. Adjustable differential makes testing easy and efficient. However, the pump is a bit heavy and can be difficult to transport to different worksites. Overall, highly recommend for industrial use.

Pros
  • Adjustable differential pressure settings for versatile use.
Cons
  • Requires manual pumping which can be time-consuming.

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

Definitely tricky to install

If you have a lot of time it's probably worth buying parts and making them yourself. I do most of the repairs myself at home, but it definitely wasn't fun. After de-energizing the pump and depressurizing the water in the basement sink, the next step is to drain the water into the tank. Then remove the old one and install the new one. Lots of knee time (buy knee pads and make sure you have a huge stack of rags).

Pros
  • Pressure switch
Cons
  • Long delivery time
