Common Water Issue in BC
Banging or Hammering Pipes — Water Hammer Issues
Loud banging noises from pipes when water is turned off indicate water hammer, which can damage pipes and create future leak risks. BC homes with long pipe runs are particularly susceptible.
Possible Causes
- •Water hammer from high water pressure and quick-closing valves
- •Loose pipe straps allowing pipes to move when water flow stops
- •Water pressure exceeding BC code recommendations (80 psi max)
- •Failed or missing water hammer arrestors at fixtures
- •Air in pipes after maintenance or system draining
Recommended Steps
- 1Check water pressure with a gauge — install pressure reducing valve if over 80 psi
- 2Install water hammer arrestors at problem fixtures
- 3Secure loose pipes with appropriate straps to prevent movement
- 4Drain system and refill to purge air pockets
- 5If banging persists, call for professional assessment to prevent pipe damage
