New poster here. I am creating a basement in my very TALL crawl space, giving my home 3 stories, and would like to divert a waste stack (services one bathroom up on the top story) to create bit more space. My thoughts were that the drop from the upper bath is 8' then hide the pipe in the floor joist by adding a slow 90, running 4 feet with the appropriate slope, then adding another slow 90, dropping another 8 feet to the main drain pipe. Doing this gives me a 4' hallway rather than 2.5'. What do I need to worry about? Is there enough initial drop to alleviate the chance of a clog? If it is a conern are there 'super flushers'? Thanks.

I bought a foreclosure residence. The house is about 200' from the road where I connect to "city" water. The home has a huge, plastic water tank and a pressure pump system. Realtor said this was needed because of low pressure. The house is about 2 or 3 feet above the road with a gentle grade. The mystery is that neither of my neighbors have such a system, no pressure problem and one is higher up the grade and further from road than my place. As I recall there is about 90lbs of pressure at the meter. The home was built in 69 but it has a new (3 yrs) pool. My wife and I are thinking the pool company may have suckered the previous owner into thinking they needed this pump/storage system. Since my neighbors have no pressure problems could it be that our main line is simply corroded, maybe galvanized, pipe with a restricted diameter? If we turn off the pump system we get a trickle. We're thinking we could replace the main and do away with the huge, ugly green, tank and pump and save money on the electricity bill. (and the water taste better ) We're pretty broke after buying the place. I would greatly appreciate any advice from the pros here. Thank you, Gus and Erin Valley Center, CA
