View Full Version : Drain to ejector pump?

We are currently remodeling our basement, including a new bathroom and laundry room which will drain to an ejector pump (and then into the sewer line).

We are interested in the supersump/Waterguard system, however, we don't really have room for both an ejector pump and a sump pump, and it seems like they both do the same thing (admittedly, one deals w/ sewage). Our question is whether we can have the Waterguard system drain into the ejector pump instead of a separate sump pump. Our plumber says we can, and that it's done all the time. Is that correct?

I would not recommend draining any system into a sewage ejector. If the sewage ejector lost power or had a mechanical malfunfunction the contents in the sewage liner can possibly back up into your system and remain there until someone can flush it out. Methane gas can escape out from the openings from the wall drain built into the WaterGuard (http://www.basementsystems.com/basement_waterproofing/waterproofing_products/basement_waterproofing_system/waterguard.php) system.
A sewage ejector is designed for ejecting sewage. There are no perforations in the sewage ejector liner because you want the contents to remain in the liner before it is to be pumped out while a sump pump system (http://www.basementsystems.com/sump_pump/) is designed for ground seepage (http://www.basementsystems.com/learning_center/basement/index.php). The liner on a sump system is perforated to allow water to filter into the liner and then to be pumped out.
Keep the two seperated.
