As many of you may remember, we've moved to the country and now have a well and septic tank (vs city water and sewer).
We have a small-ish home (~1500sqft) with a rarely used upstairs restroom, downstairs bathroom with sink, shower, tub and toilet, kitchen sink and dishwasher (also rarely used).
I'm 99% certain that the washing machine (clothes) drain dumps to a pipe that just dumps down a hill that's got a run-off ravine at the bottom. I've seen water and bubbles coming out of the ground once while walking outside, and have noticed that the grass (weeds) in the area are often healthier than in the surrounding area.
My wife likes to take a bath from time to time (pretty rare, but happens) with bath salts or bath bombs or bath oils. I've read that salts and oils and that sort of thing are bad for a septic system. I've wondered about taking the drain from the tub out of the septic system and plumbing that into the drain used by the washing machine. A lot of the stuff in the house is in series, so what that means is that the downstairs bathroom sink, shower and tub would go into the washing machine drain. Only the toilets and kitchen sink would still route to the septic.
Anyone see any issues with that or have any recommendations or alternatives?
Not a great drawing, but, take the red stuff from the left, disconnect it from the toilet drain on the left, and then run in to the drain from the washing machine (everything in red on the same drain, everything in black stays on the septic system).
Separate, but related issue. The wife loved the fact that this place has a shower and separate tub and the tub is a cast iron claw foot. Then she tried to use the claw foot. I guess it's too short (front to back) or something because she can't really sink down and submerge like you can in many more modern tubs.
