When our freshwater fill spout started coughing up water when we filled the tank, there was no need to call a doctor. I knew I could handle this one. But I did wonder why it started happening all of the sudden.
While filling up our freshwater tank a few times, we noticed water backing up and burping out of the fill hose. Upon closer inspection ? which any good RVer should always undertake in circumstances like this ? I noticed the freshwater tank expanding with air whenever this happened.
