## Description

Product Description Little Giant CV-10 Check Valve is a replacement check valve for the following Little Giant Series Condensate Pumps - VCC, VCMA, VCL-14 and VCL-24. 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. From the Manufacturer This Little Giant check valve is used for VCC, CCM, VCMA, VCL-14/24 units. It fits 1/4-Inch MNPT to 3/8-Inch ID vinyl tubing.

Review: Gets the job done - A little pricy for what it is, but it gets the job done. The check ball in my old valve had swollen with age and the pump had to work long and hard to push the condensate past the swollen ball. I thought about saving a few dollars by just removing the ball from the old valve and then installing an inline check valve in the discharge tube but, as they say, "time is money" and additionally, an inline check valve would also mean 2 more connections (potential leaks) in the discharge tube. This was definitely the better way to go.
Review: Ricky - Good product

## 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.

### ⭐⭐⭐⭐⭐ Solved my problem and saved money
*by E***E on July 25, 2024*

Our pump was not working and was shutting off our AC. I was going to buy a new one. I’m taking it all apart I wanted to see why it wouldn’t pump. Took this check valve out and it pumped like crazy. Tried to blow through valve and nothing. Took it apart and the ball had started to disintegrate. Still figured I had to buy a pump but found this. Inexpensive fix and back in business.
