How do I keep my RV’s plumbing system running smoothly?

Use a water filter to protect your freshwater lines, and check sewer hoses and connections regularly for leaks. A pressure regulator prevents damage from high-pressure hookups. Treat your black tank with proper chemicals and clean it out regularly for worry-free performance.

What kind of sewer hose do I need?

Look for a durable, collapsible hose around 15–20 feet in length. Make sure it has swivel fittings and a good seal at both ends. Hose supports help with draining and prevent kinks in the line.

How can I make sure the water in my RV is safe to drink?

Always use a potable drinking water hose and an inline water filter. Pressure regulators help prevent overpressurization, which can damage RV plumbing components and fittings.

Do I need special plumbing fittings for my RV?

Yes—RV and camper plumbing systems often use specific fittings and adapters. Keep quick-connects, elbows, and seals on hand to simplify setup and avoid leaks at the campsite.

How do I winterize my RV’s plumbing?

Drain your tanks and lines completely, then use RV antifreeze to protect pipes, faucets, and P-traps. A pump converter kit makes this process simple.If you’re not sure where to start, check out our article: Winterize and De-Winterize Your RV. It’s a step-by-step guide to getting your RV ready for freezing weather and making it easy to hit the road when spring comes!

What’s the benefit of a tankless RV water heater?

Tankless heaters provide hot water on demand, save space, and reduce energy use. They’re ideal for off-grid setups and long showers—just make sure they’re compatible with your RV’s plumbing and electrical system.
