My Little Giant condensate pump (VCMA-20ULS) started short cycling. I have a 4 year old Carrier Infinity 96 with humidifier. I checked the flow at the outlet of the pump and it's good when the pump comes on. I read that this may be attributable to a clogged or faulty check valve, does anyone else have a suggestion or potential solution?
