Earlier this year when I replaced my sump pump, I made the mistake of buying the cheap check valve that they had at the home improvement store. It was cheap and could fit 1-1/4 and 1-1/2" PVC. Well you get what you pay for and the valve started to leak this fall during one of the once in 500 hundred years but somehow happened 4 times this year rainstorms. Thanks climate change!
Keep sumpin'
Obviously I wasn't going to buy the same crappy check valve again. I needed something that looked more futuristic like a space ship. I found the wonderful 2069, 1-1/2" silent sump pump check valve from the A.Y. McDonald Mfg. Co. located in Dubuque, Iowa. Did you know that Dubuque has one of those elevator car things like Pittsburg and is actually in the biggest wine region of the US? You're on notice Napa Valley. But I digress. Back to the silent check valve of your dreams that looks like a space rocket. One delivers 8.4 million pounds of thrust, while the other ensures that 8.4 million milliliters of dirty sump water doesn't flow back into your sump pit. See if you can tell the photos below apart.
This isn't any ordinary check valve either. It has a two stage system just like a rocket booster. In the photo below you can see that I used a magic wand (don't ask!) to push through both valves. The valve closer to you is two semi-circles and the further one is the typical, full circle flappy valve. I'm guessing that the semi-circle valves close faster and limit the water that reaches the second valve, minimizing backflow to nearly zero million milliliters. Two stages = two checks = sqrt(quadruple checks) = twice the piece of mind . Thus completing my proof that this is the best check valve that American money can buy.
