Well, now it's eight years later and our pressure is still poor. For
example, if I have the lawn sprinkler on and flush my toilet, the
sprinkler just about stops.

I'm hoping that there is a reasonably simple way that I could test the
water pressure in my home. Any gauges or methods that I should be
aware of?

I'm located in Calgary, AB, Canada.

There have been some good suggestions, but I would start with water
supplier if on a municipal supply. Ask what normal pressure is .
