Silent Check Valves: Do They Stop The Thumping? YES!!! (before and after test)

Update #2: May 2020: Instead of replacing the check valve I took the suggestion of someone that commented and raised the check valve higher up. It works great again! If and when I'm able to upload a new video I will. You may also want to install the check valve further from the pump so the thumping sound doesn't come back.

Update #1: April 2019----- It's been about 3 months and this check valve has stopped working. The thump has returned and I'm going to have to remove this check valve and try a different brand. Frustrating to say the lease that it didn't last.

Silent check valves are a great way to silence that annoying "thump" or "bang" you are hearing every time your sump pump or sewage/ejector pump run.

After installing a new sewage pump I kept hearing a "thumping" or "banging" noise when the pump ejected the water. It was driving me (and my wife) crazy. Anytime we used the bathroom downstairs or washed clothes in the washing machine we had to listen to the annoying thumping noise from the regular check valve.

I found that the only solution was to replace the original check valve with a silent check valve. In the video you can clearly see that it reduced the "thump" to virtually nothing. It worked great and was worth the money I spent on it!

The one I installed is made by AY McDonald, there is a direct link to it below.

My Install: The only problem I ran into was I needed a coupling to connect one side of the silent check valve to PVC and ant other side to copper pipe. A link to the coupling is also below. .

Links to the 2 other silent check valves on Amazon that I'm sure will also work just fine:

1. This Campbell silent check valve has a lot of good reviews: https://amzn.to/2sph5rS

2. I'm sure this one is good too: Zoeller silent check valve: https://amzn.to/2D4IrJL

If you need to connect 2 inch PVC to 2 inch copper like I did in the video this is the coupling I used: https://amzn.to/2CdWVpc
