I have a 2009 Landmark. I have a leak where the exit drain pipe attaches to the shower holding tank. I had it repaired in Pensacola and the leak came back within two weeks. I had it repaired in Orlando and the leak came back the following month. I had it repaired in Alabama and the repair lasted three days. The various repairman have tried covering the joint with a rubber boot; cleaning and re-gluing the joint and surrounding it with plumber putty and a liquid sealer applied over that. Tomorrow I am heading to Willis, TX. Any suggestions on a fix or a good repair service in the area?
