D., My Husband has his own Home Repair business and does small plumbing, however, your problem is complex and He said you are going to have to call a Master Plumber. I thought so, because we had similar problem. We used A Plus Plumbing, their phone is ###-###-####. Husband said pretty sure you will have to have carpet replaced but ask Plumbing Company (Tommy - Owner)if homeowners insurance will cover that. He was very helpful with us on the insurance, he handled it, for us. Did Great Job. Was very knowledgeable about the landscaping also.
Good Luck
R.
Tell him you are calling because R. said you did a good job for her and he may give you discount - I don't know. I'm sure he knows who I am because I called him 100 times with a 100 questions. If he gives me some kind of referral rebate, I'll tell him to take it off your bill.
