The guys at Right Mark Plumbing were able to diagnose my problem but they actually could not fix it. I was definitely annoyed because I knew what the problem was before I called these guys and I told it to the guy on the phone. I really wish he would have told me then and there that they would not be able to fix it. Instead he sent a crew out to confirm what I already knew and to tell me that they could not fix it. I had to pay these guys to tell me information I already knew. To top it all off the people they recommended who could handle my problem I have called 3 times with no answer. Just an all around bad experience.
