RV plumbing keeps your freshwater flowing and your tanks draining properly. From faucets and valves to drain fittings and tank accessories, these components are built for the unique demands of RV water systems—where connections must handle vibration, temperature swings, and freeze-thaw cycles.

Common RV plumbing needs

• Faucet replacement: RV faucets use standard 4-inch center-to-center spacing. Measure your existing holes before ordering.
• Valve repair: Water pump bypass valves, tank drain valves, and shut-off valves often use 1/2-inch or 3/8-inch fittings.
• Winterization: Bypass kits and blow-out plugs protect your system from freeze damage.
• Leak repair: PEX fittings, hose clamps, and thread sealant solve most drips.

Before you buy

• Know your connection sizes (1/2-inch ID PEX is most common in RVs).
• Check if you need fresh water rated (blue) or gray/black water rated parts.
• For faucets, confirm the number of holes in your sink or counter.
