Eliminating Pipe Vibration During Zone Transitions

A KwikDial system's pipes vibrate violently and make loud noise whenever stations switch. This "water hammer" effect occurs during the brief overlap when one valve opens before the previous fully closes.

Root Cause

Simultaneous valve operation creates a momentary surge in flow volume, causing pressure spikes that shake unsecured pipes.

Solutions

1. Secure piping: Install pipe clamps/straps on all accessible runs to prevent movement
2. Pressure regulation: Install a pressure regulator on mainline to reduce system pressure (and thus flow velocity)
3. Adjust valve timing: Some controllers allow adjusting overlap/delay between zones
4. Water hammer arrestors: Install at strategic points (especially near valves)

Start with pipe securing—it's the lowest cost fix. If vibration persists, a pressure regulator set to the minimum required for proper head performance (typically 35-45 PSI) reduces surge energy significantly.
