Secure Zigbee protocol

Secure, reliable communication keeps your home protected at all times.

Check your water meter

Your meter can reveal a hidden leak.

Every home on a city or township water system has a water meter. It’s used for billing, but it can also be an early warning system for leaks.

Before water enters your plumbing, the meter records every gallon. If your main valve is shut off but the meter is still moving, there’s a leak somewhere in your home.

In most New Jersey homes, the meter sits near the front of the property and reads like an odometer, in gallons or cubic feet. Watching your readings helps you catch leaks early and save money.

Know the signs

Common signs of a water leak.

Be on the lookout for these signs that your home may have a plumbing leak.

  • Standing water or soggy spotsPuddles or soggy soil near the meter or main line can mean an underground leak. If it’s on your property, call a professional.
  • Debris inside the meter boxDebris or standing water in the box could mean a malfunctioning part, inaccurate readings, and higher bills.
  • A sudden jump in your water billCheck the red flow indicator. If it spins while every faucet and appliance is off, water is escaping somewhere.
