![]() ![]() The top holes are for your discharge and vent line. Also if you have a look at the pre-packaged system there should be a gasket that comes with it that is used when you cut a hole in the side of the tank for your 3-4” drain line. Maybe the small pre-packaged tank will work fine for your application. When my pump shuts off at the 10 gallon minimum there will be 25 gallons of back flow from my line, putting me at 35 gallons nominal capacity used. So that gives me a 35 gallon buffer to cover for power outages or a pump failure. So when the pump activates there is 55 gallons of tank capacity used. The pump is set to come on when an additional 45 gallons of sewage enters the tank. The pumps can’t run dry so in my case there always has to be a minimum of 10 gallons of sewage in the tank. To answer your question here is the explanation for my 90 gallon tank. Just to clarify my 90 gallon tank is my pump basin. (I think Zoeller does, too.)Ĭlick to expand.I’m by no means saying this is what you need for your application, I’d suggested getting a professional to look at it. The control is electro-mechanical (No IC's or other electronics) so anybody's off-the-shelf relay or breaker can be installed if one ever fails.Ĭrane also makes very small pre-packaged Barnes residential systems for quick installation. Personally, I was impressed with the pump's construction and with the controls. (Piping under the lake is what got them involved.) ![]() Also, EPA & the state DNR approved the Barnes with no problems. They haven't had any problems in summer or winter. I think flow was specified at 10 gpm at 75 PSI. The run was over 1 mile and the lift was about 142 feet in the run. The discharge pipe went underground across the island, under the lake bottom, up a road and to the mainland municipal system. This was at a friend's year-round island house to pump the whole house's sewage. One may suit your needs.Ībout 5 or 6 years ago, I installed one of Crane's Barnes EcoTrans Omni Grind Plus grinder pump systems to build a pressurized sewage system. The stainless steel blades, driven by a motor, then start to rotate. As the water level rises, the water pressure activates a microswitch causing the macerator device to turn on. I'm pretty sure they make small ones to suit your project.Ĭrane (not the plumbing fixture company) makes Barnes systems and pumps in very small and very large range. The toilet is flushed and the effluent is discharged by gravity through the rear spigot of the fixture into the macerator device, positioned behind the fixture. I know a few people who switched to Zoeller residential sewage ejector (and sump) pumps after repeat failures from other brands. The plumbers and service electricians liked them due to very infrequent service calls. Some systems were smaller and some were huge industrial multi-pump installations. When managing the skilled trades & mechanical infrastructure for a large corporation, we used a lot of Zoeller. The plumbers here will know more than I about residential pumps, so let their comments over-rule mine. ![]()
