Water hammer

Banging pipes after a tap or appliance closes deserve investigation, especially if the noise is worsening.

Understanding the issue

Start with the right diagnosis.

Rapid changes in water flow can cause pressure transients. Loose supports, quick-closing valves and supply pressure can all influence the symptoms.

How we approach the work

A plumber can examine pressure, valve operation and pipe support before recommending a suitable remedy.

Before you book

The loudest sound is not necessarily where the fault begins; note which fixture triggers the noise.
