My water pressure in the neighborhood sucks. I want to install a pressure boosting pump. How do I size it? What is a good brand, and who carries them?

The house is a 2 family, 2 baths, 2 laundry's, 2 kitchens, and lawn sprinkler..

Most plumbing supply houses carry them. The most popular is Amtrol

Amtrol would be the way to go BTW there made in USA right in RI there good money your looking @ 700.00 and up,that is if you go with an Amtrol.

sometimes they have a pressurized tank with it too....

we used to get up to 60 psi with it .....or you could adjust it up.
