I did kind of a dummy thing when winterizing in October but it turned into a small mod of sorts.
I winterized twice with no problems until I read something here about making sure the city water inlet hose had pink stuff in it. There is a check valve behind the washer and screen that prevents water from shooting out if you are running water from your FW tank and pump. Dummy me always curious to see how things work pressed on the check valve while the system was pressurized and got a face full of pink stuff. In the process it dislodged the rubber washer that seals the check valve. I must have sat there for an hour with tweezers and every other tiny tool I have trying to reseat the washer. In the end, I got fed up and ripped it out. Found a matching size washer at Lowes at sat down at the kitchen table to rebuild the valve. Pleased to say everything held pressure properly with no leaks when I de-winterized today.
This old closed thread from the Class A section was very helpful.Here's the mod.... The rubber flap that covers the fresh water inlet had crumbled apart from the sunlight. So while I had everything apart, I got a tiny piece of stainless chain and a pipe cap and created a new cover.
