How do I check my water pressure without a gauge?



How To Test Water Pressure Without a Pressure Gauge

  1. Turn on the sink and shower in the bathroom.
  2. Flush the toilet once.
  3. Watch the flow of water in the shower.
  4. If pressure visibly drops when the toilet is filling back up, then there is a good chance that the water pressure in the home is compromised.

Will a bigger pressure tank increase water pressure?
