So I went by the dealer I purchased my unit from. Talked with one of the service techs. he was well aware of the problem. Apparently at the factory, they decided not to connect that vent by the input to the tank, thus forcing the overflow to release pressure, and water. He had created a fix, but I couldn't really understand what he did, plus he didn't have the part that he used to correct. He did suggest that i attach a fitting to the overflow tube that has the ability to scre on one of those plastic bolts (like you see on your drain hose). He said that once you fill and the water starts coming out, you can scre in the plastic bolt. Probably the same principle as stopping the flow with your finger. He does NOT suggest you close it prior to filling since it will cause back pressure and damage the tank.
If anyone wants to see a picture of what I bought, send me an e-mail (email@example.com
) and I'll send it to you...not sure how to attach a file to this message
