What’s the right way to empty my RV’s black and gray tanks?

Empty the black tank first, then the gray tank. The gray water helps rinse the sewer hose and leaves the system cleaner before storage.

Why does my RV sewer system smell bad?

Odors are often caused by tank buildup, clogged vents, dry P-traps, or insufficient tank treatment. Regular cleaning and proper tank maintenance help prevent smells.

How often should I clean my RV black tank?

Rinse the tank after each dump and perform a deeper cleaning periodically using a tank rinser, flush valve, or cleaning treatment.

Why won't my tank sensors read correctly?

Tank sensors often become coated with waste buildup, causing inaccurate readings. Cleaning the tank and sensors can often restore proper operation.

Do I need a sewer hose support?

A sewer hose support helps maintain proper drainage flow and can reduce standing waste in the hose during longer campground stays.

What's the difference between manual and electric waste valves?

Manual valves are operated by hand and are the most common option. Electric valves allow you to open and close the valve with a switch and can be more convenient in certain installations.
