I finally took my holding tank out today and found that one of the 4 threaded inserts, located on the bottom at each of the 4 corners, is leaking. They all look a little rusty, but only one is leaking. Funny, they aren't even used, as the tank is held down by the fittings on the outer bottom of the 4 sides of the tank. Any idea of how to fix this leak? I plan to call Dometic/Sealand tomorrow, but thought I'd post here, hoping someone had the same problem. The model number is HTS28. I have a hot air plastic welder and will be picking up a pack of HDPE welding sticks tomorrow. I don't know of any othe r way to fix the tank, other than plastic welding it. A new tank is $800.00, which is way more than I'd like to spend on a new tank.
