|In response to Re: Thump with injector pump.|
We have a similar problem with a new installation of an ejector pump which drains a basement shower/toilet and washing machine. The vent (also an octopus set-up) was unclogged by Roto-rotor but the problem remained. I was wondering if the solution previously posted solved the problem or if there is any new insights.
: The "thump" sound comes from the check valve seating with the weight of the ejected waste still in the line after the ejector pump shuts off. The splesh "burp" in the upstairs toilet is a result of the weight of the water that is not completely ejected slamming back down against the check valve. You can assume that the ejector pump is operating correctly to elevate the waste water, but there is a blockage in the sewer line downstream, and the pressurized waste water cannot exit in the amount of time the ejector pump operates. Call a Licensed plumber to rotosnake the gravity flow portion of the main all the way through the lateral to the main sewer line in the street.
: : We have a sewage injector for our downstairs bathroom. Whenever it starts up, it seems to pump the liquid into the sewer line above, then there is a loud "thump". Also, the "thump" causes the upstairs toilet to "burp", you don't want to be sitting on the upstairs toilet.
: : -- The downstairs bathroom line and the injector vent both go into an octopus that is below the upstairs toilet.
: : Help!
