Ok now I have a situation. I had friends staying in the RV for the past week (long story). The black tank is full to the point where it's now overflowing. I plan to go to Home Depot to get supplies today. Here's the plan - advice would be appreciated.
This is the end of my sewer run - it runs about 45 feet to the left, takes a 90 and goes another 30 feet, takes another 90 and goes about 5 feet and then out through the wall. I plan to take that cap off the end and replace it with some sort of reducer that will allow me to hook up the sprinkler line adapter in the 2nd picture:
Here's the sewer line relative to the window where I plan to bring the sprinkler line in.
So hopefully it will all work okay. I plan to run fresh water through it first to make sure it's all good.
