PROBLEM:

 WATER LEAKING FROM PAN 

 
1. (CAUSE) Leaky drain pan 
 
(REMEDY) Locate leak and repair pan. 
 
2. (CAUSE) Loose evaporator, drain or condensate pump hose 
 
(REMEDY) Tighten connections. 
 
3. (CAUSE) Defective condensate pump or excessive lift on pump 
 
(REMEDY) Examine to see if elevation exceeds 20 ft. (if it does, a larger pump will be required). 
Otherwise, change pump if defective. Pump will operate properly against 20 ft. of water total head pressure 
on pump. If combination of vertical height and horizontal drain line exceeds 20 ft. of water pressure drop, 
problems will occur.
