- Hot water pressure has sudden changes occasionally.
- Changes to hot water pressure are accompanied by loud clanging in walls in our townhouse (four floors), especially when pressure is restored.
- Cold water has never been an issue.
- The water heater seems fine - pilot light on, pipe is hot coming out of heater and heater turns on at appropriate time.
- Seems to occur more often when our washing machine is running, I don’t know if they’re related.
