This Valterra 200-CU15 union check valve is made of clear schedule 40 PVC (polyvinyl chloride) for strength and resistance to corrosion and mild chemicals. Its EPDM (ethylene propylene diene monomer) seal resists degradation caused by water and oils, and the swing/spring construction of this valve makes it possible to install it in any position. It has a 1-1/2" slip connection at each end, which must be fastened with glue, a maximum pressure rating of 150 pounds per square inch (psi), and a spring tension of 1/2 lb. This check valve is suitable for use with landscape and irrigation, pool and spa, aquaculture, and general purpose applications.
Check valves have two ports and restrict the flow of fluids and other loose materials through a pipe or passageway to one direction. Flow enters through one port and exits through the other, closing when flow reverses or stops. Two common types of check valves are ball cone valves and swing check valves. A ball cone valve utilizes a spring-loaded ball seated against a cone-shaped interior surface to stop the flow of fluid in a forward direction, and a swing check valve has a movable disc on a hinge to block reverse flow. Check valves are rated by their cracking pressure (the minimum upstream pressure required for the valve to operate), and they are used in various water, gas, air, and steam lines.
Valterra Products manufactures and distributes valves, hoses, sewer systems, and pool and spa products. The company, founded in 1981, is headquartered in Mission Hills, CA.

It was perfect for 18months.. Vertical install and after 18 months of use there is small amount of back flow. Wouldn't matter but we're using for Laundry machine.. a little back flow can cause staining of whites.Probably install a new one soon.

So after installing a high-end, very expensive variable-speed water pump, the water system wasn’t working right. One of the issues we surmised might be happening is back pressure on the supply line. A check valve seemed to be the next step in eliminating variables, and so we decided to try this unit. Part of the decision to go with this particular piece of equipment was 1) it is see through. We would immediately know if our theory was right or wrong by visual confirmation, instead of guessing or installing unnecessary pressure gauges. 2) it can be used in a horizontal configuration. Most other see-through check valves are designed to only work in vertical applications. This fit our water system design perfectly. Happy ending: this unit worked like a champ! It fixed the problem we were experiencing. We could see that there was slight incoming pressure with the ‘flap’ being slightly open, and once the pump kicked on, we could see right away that the flap closed/sealed tight against the housing. I will probably buy more of this unit in case it ever fails in the future. For the price, this is an inexpensive insurance policy! Highly recommend.

Silent. Not a sound. Easy to install. Make sure you use the specific abs to pvc glue if installing on abs, this is made of pvc

We use check valves on all our systems and this an accurate. And quick closing , non fluttering check valve, pay attention to flow orientation when installing and don’t get glue inside !

It requires pretty precise measurements and seems built for heavy duty and long life. It's been working well and hopefully will outlast the valve it replaced.

Used these on 1/2 HP sump pumps with vertical discharge for mostly clear water. They are secure and don’t blow off like the ones with a rubber sleeve and hose clamps.

I broke 4 or 5 of the home depot ones that have a seam in the middle. This one works perfectly and easy install, no leaks.

I do home renovations, I bought this and installed this for a customer. It works awesome and looks good too. It was so easy to install even a monkey could do it. The price was great too. This is my new "go to" check valve for all my future jobs.
