Water meter running when nothing is onDelft, South Holland

If your water meter keeps spinning even when every faucet, toilet, and appliance is off, you likely have a hidden leak. Underground slab leaks, pinhole corrosion in copper lines, or a silently running toilet flapper can waste thousands of gallons a month and cause structural damage before you ever see a puddle. A licensed plumber can perform a pressure test, use electronic leak detection equipment, and pinpoint the exact location without tearing up your home.

Why this is common in Delft

Plumbers in Delft deal with hard-water limescale, ageing pipework in the older stock, and — on the wet Dutch subsoil — drainage, cellar pumps and damp. Gas and water work runs through recognised installers (InstallQ).
