Lay-Z-Spa Air Blower Assembly Non-Return Drain Valve
Fix High Pitch Whistle
Cleaned, Tested & Ready for Installation
Common Problems
A defective drain valve commonly presents as a high pitched whistling noise while the blower is operating. This occurs when the internal rubber valve degrades due to prolonged exposure to chlorinated water, causing the material to harden and become brittle. As the seal integrity diminishes, pressurised air is able to bypass the valve, producing the audible whistle.
