I am installing the basement drainage rough-in for our cabin in Colorado next week. The basement will have one bathroom group (WC, BT, Vanity) plus a utility sink that will share the vanity drain/vent. This will connect to a sewage ejector basin about 20 feet from the bathroom then will be lifted about 5 feet to the main septic line to the septic tank. At this stage we are just installing the under-slab components and I am good with the drainage lines and venting for the basement fixtures but the CO inspector did say we would need to complete a drainage water test as listed in IPC 312.2 drainage and vent water test. I have never done a water test on a drainage system and was wondering what this should look like. We will just have stubs that will come out of the slab for all the fixtures/vents and the sewage ejector basin at this stage prior to preliminary inspection. To complete the water test with not less than 10 feet of head of water do we just add a 10 foot section to a vent (or fixture) stub and plug all other fixture/vent stubs along with a plug at the basin inlet? I can't find any pictures or videos of this online in my searches so was curious as to how this should look for this section of the drainage piping. Any input would be appreciated.
Thanks!
