While our Class A was being repaired at a dealer in Texas, they decided to "winterize" the fresh water tank. They used something pink and it clogged all the faucets and shower head. I have cleaned & flushed the tank several times, and even added bleach but the water still smells like something died in it.
I've had motorhomes for over 30 years and I have never winterized one and I have never had a problem with smell.
Any ideas?
