Water pressure at campgrounds can range from a trickle to a pipe-bursting 100+ PSI. Hose fittings, regulators, and adapters help you connect safely to any water source while protecting your RV's plumbing from damage.

Water pressure regulators

• Why you need one: RV plumbing is designed for 40-60 PSI. Higher pressure can blow fittings, burst hoses, and damage faucets.
• Types: Fixed-output regulators (usually 40-50 PSI) or adjustable regulators that let you dial in your preferred pressure.
• Placement: Install at the spigot, before your hose, so the entire system is protected.

Common fittings and adapters

• Hose-to-hose connectors: Extend your reach or repair a damaged section.
• Elbow fittings: Reduce hose kinking at tight angles.
• Quick-connects: Snap-on fittings for fast hookup and disconnect.
• Y-splitters: Run two hoses from one spigot.
• Thread adapters: Convert between garden hose thread, NPT, and metric sizes.

Hose materials

• Drinking water safe: White or blue hoses are lead-free and safe for potable water.
• Standard garden hose: Fine for flushing tanks or washing, but not for drinking water.
