Has anyone put in an ejection system for sewage
Comments (3)if injector system is comparable to pump grinder system, I would definitly go with the down the hill idea, in my area, you are required by code to have two pumps, you get to have twice the fun of repairing clogged pipes. grease and powdered soap cling to them like they are hugging. Also, keep in mind, they aren't working during a power outage, unless you have a back up generator....See MoreEjector Pump vs. Gravity Flow
Comments (8)Why not have your existing tank pumped dry, excavate it and reinstall it at a lower depth so that it will receive sewage from the first floor toilet? If the leach field is low enough for a second tank then it must be low enough for the first one. One tank, no pumps, nothing new to buy, it's a one day job and it solves all your problems....See MoreBasement bathroom plumbing options (pump up to septic line)
Comments (4)Either type of pump system will work equally well however before you begin ordering a sewage ejector pump and bathroom fixtures you need to determine if your house sewer line is large enough to handle the additional load. By example, under the International Residential Code (IRC) all sewage ejector pumps MUST BE rated for a minimum discharge rate of 14.2GPM. To determine the load on the sewer line we are required to compute the load at 1.5 DFU's (Drainage Fixture Units for each gallon per minute from the pump, therefore the minimum load would be 14.2gpm x 1.5dfu = 21.3dfu's. The gravity flow line receiving the discharge from the pump must be sized sufficiently to handle both the existing load on that line plus the additional 21.3dfu's from the pump. Under no circumstances may the pump be discharged into a horizontal branch line because the code maximum for a 3" horizontal line is 20dfu. The maximum allowable load for a 3" house main drain or house sewer line is 42dfu. Before you begin you would need to make a list of all fixtures in the structure that are connected to the drainage system, then use the code tables to compute the existing DFU load. Most residential structure today have a 3" main drain and house sewer which is generally more than adequate for a gravity flow DWV system, but when you add in the discharge load of a sewage ejection pump, in most instances it will require increasing the size of the house main drain from the point of tie in to 4" and the house sewer line from the structure to the septic tank will also need to be increased to 4"....See MoreCurbless shower/wet room in basement bathroom with ejector pump?
Comments (18)How often does your power go out? Adults and teens in the house should be cognizant that when the power does go out, the half hour shower will have to be postponed but it's not like it has to be an overriding fear that prevents the bathroom from being used. Commercial and institutional buildings with basement restrooms often have the same setup, albeit larger systems. My laundry tub, washer and basement bath all go into the same ejector pump pit. My power typically will only go out due to a severe thunderstorm and be out for 4 to 6 hours tops. It's pretty obvious that the power is out and the basement bath, washer and laundry tub are just not used at those times. The toilet is older and has a 3.5 gallon flush. If the pump has just cycled, It takes 2 flushes for it to kick in again. My guess is it would take at least 5 or 6 flushes to start coming out of the shower drain. Maybe more - I've never tested it. The pit doesn't fill to the top before the pump kicks in; there is some buffer there as well....See Moreken06
