    I have a dual sink setup and the garbage disposal sometimes blows water back into the other sink. Can I use this on the sinks drain to stop this from happening?

    No, this device is not designed for sink drains. Mike

    This PVC check valve is designed to prevent backflow, so it could potentially stop water from the garbage disposal from blowing back into the other sink. However, it's designed for non-potable water applications according to the product details. Since kitchen sinks handle wastewater from dishwashing and other activities, using this type of valve might be suitable. It's crucial to ensure the valve can handle the specific wastewater characteristics and volume from your garbage disposal. If you're unsure, consulting a plumbing professional is always recommended for the best solution for your dual sink setup.

          Shot water from seam - caused flood, 2 months after use
          I installed this 1/2" PVC valve less than two months ago. I came back from a 1 week vacation only to find water spewing out of the center seam that connects the top and bottom halves. See picture. I figured I would reconfigure the 1/2" pipe with a 3/4" valve* and requisite piping. I shut off the water and went back to HomeDepot (plumbing supply store not open on Sundays). The only product line that HD carries is this 2-part Proline valve.. in all sizes (1/2", 3/4", 1", etc.). My next option was to buy a brass valve, but there were none in stock. Gigantic teeth gritting sigh. I bought the exact same part again (and the necessary couplings) with steam coming out of my head. This part is NOT well designed. Why... why... why would you build a 2-part fitting that is under pressure? 1 have four, 3/4" PVC one-way valves on my property - all on the same water line for the past 15 years. I have had zero problems with those. None of those PVC valves have this 2-part design. They appear to be a single unit design and they are working flawlessly.

            Well built, but not fully operational
            This check valve is well built, but the way it operates is unsatisfactory. I have added 2 pictures to show the valve open and closed. When the valve is closed, it functions right. When the valve is open, it is worthless: it opens a 1/8" circle., it passes only very little water. I was planning to use it on a sump pump, which passes a 2 inch solids. If I install this, it will barely pass 1/8 inch solids, or block everything together.

            Yes, it stops the water from coming back through the skimmer.
