The Little Giant CV-10 Check Valve is a precision-engineered replacement part designed exclusively for select Little Giant condensate pumps. Featuring a 1/4-inch MNPT inlet and 3/8-inch barbed outlet, it prevents backflow to avoid rapid pump cycling, thereby extending pump life. Constructed from durable acetal with a Buna-N ball and nitrile O-ring, this compact valve ensures reliable, leak-resistant operation under pressures up to 290 bars.

Great product
Worked perfectly to replace my broken check valve for my condensate pump.

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.

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.

Replace once in a while the little rubber bearing deteriorates.
Perfect solution to my problem. The drain machine was leaking because the check valve was plugged.

It Works but You Only get the Black Part
I am delighted with the check valve and it does what I want it to do. Beware. The clear or light colored bent part is NOT included and I am disappointed no one from Little Giant made it clear and precise. It would have made my installation so much more simple, but... It slows down the water flow and that is what I wanted so that I do not lose too much at one time. Overall, even with my disappointment with the other part, this is the perfect valve for its use.

Replaced a broken valve
Yes!! Our check valve broke off because of bad placement of pump and the drain tube was old and getting stiff. Thought I had to buy a whole new pump but this replaced the old one that broke with no issues. Our pump is a Wayne pump and they don’t make them anymore and are hard to find. This was an easy fix. Bought two just to have another one on hand.

The installation man suggested a new pump which cost is from $150 to 350. We just replaced the valve that fits several pumps and can use it without purchasing a new furnace water pump. I don’t understand, why a contractor would suggest a new pump instead of ordering the valve, which he could do himself and charge a double cost, which would be acceptable. The cost of the valve was only $10 and it was replaced with no problem !!!!!

My husband wanted me to order this since the pricing was so good. He said it is exactly what he was looking for and would do the job.
