sewage ejector pump check valve
Downstairs bathroom drains, including washer runs to pump which raises it about 8 ft to then flow by gravity to my septic. The check valve is extremely noisy- even viloent to the piping system. My plumber suggests removing altogether, which he said he did with his father's and has had no problem. I'm concerned about run back and maybe should search for a "silent" check valve. Plumber doesn't seem to be aware of this option. What do you think?

They make silent check valves. I'd never suggest removing the check valve totaly, that's would be a mess waiting to happen.

I've been annoyed by the same problem. Everytime the check valve on the pump line for my washer and dehumidifier/condenser drain slams shut it sounds like someone is hitting the floor with a hammer. Was told "that's just what check valves do" so I accepted it.

Just did a quick search for a silent check valve and found this on Amazon. $25/shipped if you're a prime member. There are good reviews and a video of operation on the Amazon page.

Mine does the same after installation of a new pump and check valve.
I did upgrade my pump from a unit from the supply house....all cast iron frame/impeller/etc (approx $300).

The check valve I bought is the rubber bodied one with the clamps as opposed to the glue in type my ejector pump has (which is silent).

I think I have yet another project.....sigh!!
