I had a plumber come out to my house yesterday. He didn't do anything except cause issues and make a complete mess. He used my garden hose and tried to flush the RV sewer. Now I have to buy a new hose as it is covered in sewage. He also pulled the sprinkler piping from my French drain that will need to be repaired and cost me money. AHS refuses to fix the problems. I called another plumber on my own today that snaked the RV line and fixed the issue. User's recommendation: DO NOT RECOMMEND.
