My sewer guy warns me that many 'flapper'-type valves are prone to
failure - I wonder if this product is a possible solution since it can
be removed and cleaned without needing a manhole in my yard (or digging
up the yard).

TIA,

No experience with that one but it looks like a great device.

Does he say if your city will approve it?
