We have some sort of plumbing, draining, septic issue. To start, when we moved in we noticed the shower drain didn't drain well. It's very slow but gets there eventually. I tried getting tools down it but always hit something and couldn't go forward so gave up and figured I'd get to it eventually, it wasn't a huge issue to wait for it to drain. 

Then my daughter got sick and had a whole vomit and poo episode and clogged the toilet really badly. I scooped out all the water, got all the crap out, flushed it and it worked. 

Now, just a day after that, I started smelling poo around the house. So I thought maybe I got some on my clothes or shoes and just needed to wash. The laundry in the basement... was surrounded by poo water. I panicked, called people, they said $1500 just to come look. I'm a struggling single mom, I don't not have $1500 just to have a look money. So now I'm trying to solve this on my own.

Fast forward to today. We have stopped using all water in the house because when we use any of it, the poo water starts flowing more. It's not gushing, it's a calm flow. Showered at the gas station so dunno if volume changes that. 13 hours later (thanks work) I arrive home determined to soak up all the water with wood pellets, just to find all the poo water is gone, just remnants of poop and toilet paper on the floor. I'm scared to use my water. Idk what I'm dealing with. 

I figure if it's a huge issue, we would still have poo water? Is this simple? Can I snake something? Can I put the green goblin powder somewhere? What can I do so we can use our water without creating such a disaster? Because it's gone this doesn't seems like a $1500 thing? Any advice please, I am a single mother who just wants a healthy home for her kids and this is not healthy. 

Pic three shows a toilet but on the floor is a weird pipe thing that used to be capped. The cap is off and the poo water and tissue paper is coming from that.

Desperate for any help
