Ask Me Help Desk - Septic inlet connector

I am trying to connect a waste pipe to a septic tank but the building is on the opposite side of the inlet (just about 180 degrees). From where the waste pipe leaves the toilet to the inlet is less then 10 feet and the drop from toilet to inlet is about 4 feet. How do I do this? What kind of connectors do I use and at what type of slope? Thanks.

Susan I am not sure on your angle to tank sounds like you have to go past the tank tie in. Are you sure that's the inlet side? If so you need to expose the old inlet pipe. Now use a T fitting. Look at the Tee and you will see inside the Tee there is a slope to control directon of flow. Now when you cut the line leave enough room for the T to couple over the old line and a short stub on the other side of new T. Now use your cut out piece to fit between the new T and the other orginial line.. Now to make that connection sealed you will need a "slip coupling" This needs to be put on and slid over your last connection piece. Now keep in mind before you cut your main pipe to tank. Lay your T on the existing line then lay slip coupling beside that and leave enough room between the T and Slip to glue and slide slip coupling. When you add new pipe off new T and now yo need to get away from side of tank don't use a 90 degree elbow to make that turn(angle) Use to two 45 degree elbows with a foot or so in between that. You should never use a 90 in buried line ( clog point)If you can avoid it. If you can when you pipe back to the house keep in mind a cleanout. It's a T in the pipe s you can put a pipe from the new buired line to top of existing grade. The a soilid cap at grade ( don't glue cap) Keep in mind a toilet needs vented withn 3 ' of the toilet. Mim slope is 1/4 inch per foot . You have plenty of fall. Now I hope you took into acount the 3' depth line in gorund right out side your block wall and ten to tank.. Pa. here is 3' They are making us use 2b or rice stone to bacl fill 6" over pipe than dirt. To tie into an existing line to toilet use anther slip coupling. The other coupling inside could be a fernco coupling. I need more information for that. Hope this helps.

Thanks. Yes, I know it's the inlet because I've had a trailer hooked up to it for the past year. The problem is that the land I'm on has a foundation that was built years ago and then abandoned. The foundation is a straight shot to the inlet, but I'm not building on the foundation. I'm actually plumbing a yurt as a bathouse and it sits south and a bit east of the septic - hopefully not too much on the leach field though the yurts are on cinder and pier blocks and can be moved if absolutely necessary. It's a small piece of property and this is the only place I can put the yurts and still be within existing easements and set backs. Thanks for your help.
