Hi! We are full-timing and currently outside of Houston. We have a 2016 KEYSTONE MONTANA 3950BR. We are living through the epic winter freeze down here and without power to the rv for three days with below freezing temps at night. We did not turn on the tanks heaters. Our two grey water tanks are empty and fresh water is about 1/4 full. Now our black water tank is FULL. Husband feels sure that the valve to empty tank is frozen. Not sure about the condition of the sewer hose. We always leave the grey water tanks empty (separate valve and always open except when dumping black water). With that being said, would it do me any good to turn on the tank heaters (which are not marked) to heat the black water tank. Hubby doesn't want me to pull on that valve and possibly break it....that would be a disaster! Black water showing FULL and grey waters showing EMPTY. I pray I have made 'sense'. Help a little old lady out and keep me out of trouble with hubby!!! Thanks!
