ZelleI have two of these for sale. Listing price is for each one. I replaced flapper check valves on my aquariums and never looked back. These are so much more reliable, quieter (no knocking or chatter when closing), and easy to maintain and clean. These two were extras that I bought ($83 each) but will never use. Well worth the expense to have a reliable, maintainable check valve in my sump. Slip x Slip standard 1” PVC connections. I highly recommend attaching to unions on both ends so that it can be removed or moved to new configurations when necessary.
I can ship these if you want to pay for shipping.
