Q:which check valve is compatible with this pump?
by|Feb 1, 2024
1 Answer
Answer This Question

A:  The selection of a check valve is not primarily based on the brand or style of pump. The selection of a check valve is based on the specifics of that application. Applicable factors would include pipe material, size, direction of flow, type of fluid being pumped, etc. For example, if I am pumping vertically, I might select a swing check because the weight of the water column will close the flapper tightly. But if pumping on and angle I may need to use a spring check to get a waterproof seal. If not, the fluid that has already been pumped and is sitting aft of the check valve may flow backwards into the pump and cause it to cycle over and over. Again, let me repeat you primarily use a check valve so that fluid that has pumped does not run backwards due to gravity when the pump turns off. If that happens that fluid may be sufficient to fill the sump and cause the pump to turn on again. This can create an unnecessary feedback loop. Now let’s say you are going to use this pump to protect your basement from ground water and you will pipe it with 11/2” PVC pipe and fittings. You intend to pump up 8’ and elbow outside and dump the water on the driveway. In that case I would most likely use a simple rubber check valve like the one Home Depot offers as SKU 317149094. If you put that number in the search box it will come up. I would install it in the vertical discharge pipe roughly 8” up from the pump. Just below the check valve I would drill a ¼” hole through the wall of the discharge pipe. Yes, a small amount of water will come out of that hole when the pump is operation which is why the sump pit should be deep enough so that that water coming out the hole will still be in the sump. Why is this a best practice? Because pumps don’t pump air, they move fluids. If the sump slowly fills a pocket of air can get trapped I the volute. The part of the pump that houses the spinning impeller. The pump will not be able to compress that air enough to open the check valve if the pipe above it is filled with water. The air needs a place to escape so that water can reach the bottom of the check valve and push the flapper open. If the pump becomes air bound it will run and run and run but there will be no flow. Best of luck. Chris 978 651 3301

    Q:What is the pipe size at the discharge port?
    by|Nov 18, 2023
    1 Answer
    Answer This Question

    A:  The discharge connection is 11/2” Female National Pipe Thread. If you scroll down the Home Depot product listing page you will come to a section entitled product details. If you expand the section, you will find PDFs of the product documents. If you open the one marked specification, you will find this and other detailed measurements.

      Relief Air Lock Feature Included
      This is one of the few sump pump that incorporate the relief air value to prevent air lock. This can allow unfamiliar home owners to just plug in and operate. No need to drill a hole on the discharge pipe or blowing/sucking into the air vent at the plug. The price is more expensive than similar models, but I would rather pay a lit more than the headaches. I would prefer the neck of the base would be built higher to put a hilding clamp.

        Dependable, strong
        This pump worked non-stop for several days and now that our water is under control does a great job cycling on and off. Love this pump.
