F’ing Septic Tanks

He got really defensive as did I, I pretty much said he didn’t do his job. My wife was outside crying because we were going back and forth. Then the asshole called me out on my construction in the back yard. For pouring a concrete pad for the patio. He asked “did you get a permit for that” I said no. Turns out I don’t need one, i called after he left. I’m thinking of packing my ****, listing this house and moving back to Florida. Getting a lawyer will just add another layer of bullshit and wasted money.
Take a breath man, this is just another pothole in the road of life. Yeah it is tough to deal with but a licensed installer can fix it. The real estate folks could be on the hook for non disclosure and you may have relief coming from them. Whatever you do don't take shortcuts. Fix it right. Good luck.
