What Length RV Sewer Hose Do You Need?
Sewer connections can be directly beside the utility bay or awkwardly placed near the back of the site. Carrying modular hose sections prevents one unusual campsite from becoming a plumbing problem.
Site geometry drives the decision
Back-in depth, utility placement and whether the sewer inlet is ahead or behind the RV can change required hose length even at the same campground.
Modular sections are easier to manage
A shorter primary hose handles most stops with less material to rinse and store. Add an extension only when the inlet is farther away.
Slope matters more as the run gets longer
Longer horizontal runs are harder to maintain at a consistent downhill slope. Hose supports can reduce low spots where waste or rinse water collects.
Inspect seals and fittings
Longer systems have more joints. Check bayonet fittings, seals and clear adapters for damage and replace parts that no longer connect securely.
