Dump Valve Lube

Just wanted to share this tip again in case some have not tried this. As part of our winterizing process, I decided to pour vegetable oil into the gray and black water tanks and work the dump valves to lubricate them. Have done this before but had been a little over a year. I had forgotten what a difference this makes, valves work better than new! Decided to leave just a little in the tanks to sit against the valves through the winter to keep them from drying out instead of antifreeze.
