Hi All. I recently completed a garage addition to my home. The builder roughed in plumbing for a full bathroom. I framed in the bathroom and hooked up water and sewer this past weekend. Problem is the addition's sewer line is just a little bit lower than the connection to the exsisting main line to the septic tank so, being a gravity fed line there is standing water in the pipe ( I opened the cleanout valve to confirm this). The toilet is very slow to flush, I have to hold the handle down until all the water goes out of the bowl. It does flush however I am afraid to use it as I imagine the line will just clog up. The bathtub and sink drain just fine with no backup.Will this water eventually make it to the septic tank? It is about about a 26 foot run from where the sewer pipe exits the garage to the septic tank. Short of "lowering" the septic tank what solutions are there?I did a web search and noticed that there are sewage pumps out there. Is this the solution to push the water/sewage up the pipe to the septic tank? Would I be able to hook one up externally? Say I splice it in-between where the sewage line exits the building and the sewage line to the septic tank? Any thoughts? Pump and H/P recommendations? Thanks in advance for any suggestions.
