Zoeller 30-0181 Check Valve & Union

Each end of this valve has a stepped outside diameter; 1.25" on the end, and 1.50" next to the valve body; refer to the Customer Images. It comes with two rubber adapters and four stainless steel clamps. The adapters convert 1.25" to 1.5" or vice-versa. The 1.5" adapter end will slip over a 1.5" PVC pipe, and 1.25" will slip over a 1.25" PVC pipe. In other words, using the supplied rubber adapters, either end can be configured to 1.25" or 1.5".

It's easy to connect this device using a clamp screw. To remove the device, or slip one end off a pipe, loosen one of the clamp screws and slide the pipe out; hence "union" in the name. This feature allows removal of the sump pump for service or replacement, without cutting any pipe.

This is a full flow check valve, unlike some models at my local Lowes or Home Depot, which partially restrict flow. When a sump pump comes on, the valve flap swings completely out of the way, to allow maximum flow. When the pump stops, the flap closes to stop water from going toward the pump. The rubber seal part of the flap will eventually leak a bit, I suppose, but there is so little pressure on it when it's closed, that it should last a long time.

Our sump pumps were installed with a check valve within the sump basin, since the discharge level was less than a foot above the sump basin. When the pump shuts off, if you don't have a check valve, all water still in your exit pipe that's higher than the pump will flow back into the basin. Otherwise, the only water that will flow backward into the basin is the small volume of water between the pump and the check valve. In addition, a check valve prevents mice, insects, etc. that crawled in through your exit pipe, from making it all the way to your sump pump. When the water comes on, critters should be washed away.

We have this check valve on each of our sump pumps. Excellent product.

This check valve is a totally reliable and durable product, and it's worth every penny to know that you don't have to worry about back-flow issues. I just bought a new check valve along with a new sump pump, but to be honest, I could have kept using the 10 year old Zoeller check valve on the old pump. They recommend replacing the check valve any time you replace a pump, but these things last forever!

High quality product, worth the money. Full-flow design that should last a very long time. Much better product than the imported valves stocked at the local stores.

Packaging was a little iffy (foam-lined envelope), but the valve came through just fine.

Another quality Zoeller product.
