Water fixtures in your building are typically designed for water pressure of no more than 65 PSI. The water delivered by your municipality (city) often has much higher pressure. This results in more water being pushed through your fixtures, leaking through seals & gaskets that are designed for 65 PSI and increased maintenance costs.

Along with the volume of water passing through your water meter is a volume of air. The lower the water pressure the more volume the air will have. The problem is that 99% of water meters measure only volume, regardless if that volume is liquid or gas.

Water meters are designed to be accurate within a specific flow range (GPM). If the flow exceeds this range it can cause the meter to over-spin.

City water pressure can fluctuate significantly causing surges and pressure drops. This will cause the meter to over-spin and damage water systems & equipment. Surges also occur anytime you go from no flow (static) to flow (dynamic), such as when you turn on and off a hose
