## Description

Little Giant CV-10 Check Valve is a replacement check valve for the following Little Giant Series Condensate Pumps - VCC Series, VCL-14, VCL-24 and the VCMA Series with a date code of 25J or earlier. The date code can be found on the product label in the bottom right hand corner - see first three digits. (See image for clarification.)The CV-10 has is 1/4-inch MNPT x 3/8-inch Barbed. The part number is 599065. Check valves prevent water from backing into the pump causing the pump to fast cycle (turn on/off quickly) which can shorten the lifespan of the motor.If you have purchased a VCMA with a date code later than 25J (ie, 25K, 25L, etc.) please see Little Giant 599066 CV-10S.

Review: PERFECT! - This was a perfect replacement for the check valve that went bad. Two minutes to take out the old, install the new and the pump is working like a dream again!
Review: Much cheaper than getting a new condensate pump - Little Giant condensate pumps last forever and this check valve is much cheaper than getting a new condensate pump. Do an Internet search for "Diagnose and Fix your Condensate Pump" for an excellent YouTube tutorial on the diagnose and repair process. When diagnosing, make sure that the pump does not squirt you in the face. This is also a good time to clean all the crud out of the pump which will take a whole lot longer to do than the few minutes needed to replace the valve.

## Questions & Answers

**Q: Does this check valve need a threaded water container or is there a tightening nut for both ends?**
A: It is intended to screw into a threaded hub on the tank. But I would expect that if you had a nut of the proper thread you could put it through an threaded hole in a tank (it comes with an O-ring that could serve as the gasket).By the way, this valve does not always shut off tightly. If you need to be absolutely sure no water runs back into the tank, this will disappoint you.Best regards,Doug

**Q: Is the plastic ball spring loaded?**
A: No, it is held in place by gravity.   The water flows upward, opening the valve, and when the water stops flowing, gravity pulls the ball back to the closed position.

**Q: Will this work on model vcma-15ul 554401?**
A: Yes, if you are buying it new, it should already have one of these installed. If you are replacing it, this will work just like the new one.

**Q: Will this degrade if used with propylene glycol coolant?**
A: Up to temperatures of 140 degrees F the ABS body is resistant, higher than that it is not. That is, it would not be useful for engine radiator hoses. See http://www.ipexna.com/media/1693/abs-chemical-resistance-guide.pdf for details.

Versand könne etwas schneller sein (aber das lag vermutlich am Jahreswechsel und Feiertag) sonst alles top!
