Looking for some info (facts and/or opinions) regarding winterizing.
Our Laredo has the "convenience center" located at the rear L/H side of the pass through storage compartment. The water pump is located behind a panel just inboard of the convenience center. This places the pump about midships with the FW tank at the very rear of the trailer. My question is: Does the water in the long input line from the tank to the pump drain back into the tank? I don't plan on using anti-freeze. We will see early morning temps of 28-32 with an occasional night in the low 20's (but that is rare). We usually just blow the lines out and put some anti-freeze in the p-traps and waist tanks and on top of the toilet seal. I just don'y know about the line from the tank to the pump.
On our previous trailer, the pump was located directly above the FW tank and I assumed it drained back into the tank. I'm not sure that is the case with this trailer. It seems we would have to wait for the pump to prime (fill the long input line) each time we were to use the pump. Since we get water flow immediately, I believe the water stays in the line and doesn't drain back into the tank.
Hope all of that makes sense. Given our weather, I am probably concerned for no reason - I would just feel better if I knew there was no water in this line. Thanks in advance for any insight anyone might offer.
