Hi, I am having several plumbing issues which may or may not be related. I leased a restaurant recently, the building was built in 1974, and has seen a lot of grease in it's days. Anyways, the toilet started backing up so I had a plumber come out he ended up snaking, jetting, and putting a camera through the lines. He said I had a break and needed to replace the cast iron. Had a second plumber come out they sent a camera down and said they didn't see any breaks but I should empty my grease traps, and jet the back lines which I did.
Toilet issue was fixed so I opened the restaurant. Now there is a horrible smell if I drain my kitchen sinks. Also the mop sink never completely drains. The floor drain behind the bar which has about an inch of 2.5 pvc pipe sticking out of it (so not really a floor drain I'm assuming) overflows if I drain a sink fully and then begins to overflow in a similar floor drain in the kitchen. I ended up tearing out some damaged tile in the restroom and found rotting drywall so after tearing that out I saw what looks to be a vent pipe completely crumbled.
So many problems! And unfortunately no more money left to throw at all of them without (hopefully) a fix... any thoughts?
