Water rushes back into discharge of Sanibest after macerator shuts off
I have a sanibest which was just recently installed and it seems to work fine. But after flushing the macerating pump comes on and pumps out the water then shuts off. Then I hear a rushing of water which seems to be water coming back up into the discharge. Is this normal? Other than that it seems to work fine.

Then I hear a rushing of water which seems to be water coming back up into the discharge. Is this normal? Other than that it seems to work fine. Should the check valve prevent this and is it located in the discharge elbow?
My installation is such that the discharge comes out of the discharge elbow, goes horizontal for about 8 inches,then using 2 45 degree elbows goes down about 1 foot to 2 more 45 degree elbows, then horizontal about 8" to 2 more 45 degree elbows, then straight down about 6 feet. Then it turns about 60 degrees and goes almost horizontal but in a downward slope about 50 feet to the soil sack. Does it sound like I need to install an anti-siphon valve or should the check valve, which I think is inside the discharge elbow, prevent this from occurring? If so where in the run should I install it?
