Why Replace Your R150A-C Pump?

After years of regular use, whirlpool bath pumps naturally begin to wear out. Common signs your original R150A-C pump may need replacement include:

• Loud bearing noise
• Water leaking from the shaft seal
• Pump hums but will not start
• Weak whirlpool jet pressure
• Motor overheats
• GFCI breaker trips
• Excessive vibration
• Frozen motor shaft
• Reduced hydrotherapy performance

Replacing a worn pump restores proper water circulation, quieter operation, and the relaxing whirlpool massage your bathtub was originally designed to provide.
