Extended Plumbing Check detected a possible small leak

Last updated on 30 Jan, 2026

If you run an Extended Plumbing Check and Phyn detects a pressure drop of 4.5 psi or more over 10 minutes, you’ll receive a Plumbing Check alert. Extended Plumbing Checks run longer than Normal Plumbing Checks and are designed to detect very small or slow leaks that may not be visible right away.

This alert means Phyn detected pressure loss that could indicate a small leak, such as a drip or slow seep somewhere in your plumbing system.

What to do next

Start by checking common sources of small leaks:

  • Inspect faucets and spigots inside and outside your home for dripping

  • Check toilets for silent leaks caused by a worn flapper or fill valve

  • Look for any fixtures that may not be fully shut off

If you find and fix an issue:

  1. Run another Plumbing Check to confirm the problem is resolved.

If you can’t find the source of the leak:

  • A small leak may be hidden behind walls, under floors, or underground

  • Contact a licensed plumber to help locate and repair the leak
