RV Plumbing Parts

Keep the Water Flowing (and the Leaks Away).

Your RV's plumbing system is a marvel of engineering, delivering hot showers and flushing toilets even when you are miles from the nearest city connection. However, these systems use specialized components designed to withstand road vibration and freezing temperatures—parts you often won't find at a standard hardware store.

At Leisure Days RV Group, we stock a complete lineup of fresh water and sanitation supplies. From upgrading your plastic factory faucet to replacing a failed water pump, we have the parts to keep your rig dry and functional.

Our Plumbing Inventory

Fresh Water Systems

  • 12V Water Pumps: Replacement on-demand pumps from industry leaders like Shurflo and Seaflo. We also stock silencing kits and strainers to reduce pump noise.

  • Faucets & Fixtures: Upgrade those basic white plastic faucets to durable, residential-style brushed nickel or oil-rubbed bronze units designed for RV sink spacing.

  • PEX & Fittings: We carry the specific PEX tubing, crimp rings, and "Flair-It" (tool-less) fittings used in modern RV construction.

Sanitation (Toilets & Tanks)

  • RV Toilets: Complete replacement units from Thetford (Aqua-Magic) and Dometic (310/320 Series). Upgrade from a plastic bowl to a porcelain bowl for easier cleaning.

  • Repair Parts: Ball seals, water valves, and flange gaskets to stop toilet leaks.

  • Tank Treatments: The essential chemicals (liquids, drop-in pods, and digesters) to break down waste and control odors in your Black and Grey tanks.

Sewer Management

Don't mess around with "The Stinky Slinky."

  • Sewer Hoses: Heavy-duty, crush-resistant hoses and kits from Camco RhinoFLEX and Valterra.

  • Fittings: Clear elbows (to see when the tank is clean), donut seals, and 4-in-1 adapters for campground sewer hookups.

  • Dump Valves: Replacement gate valves (1.5" and 3") and extension handles to fix stuck or leaking waste tanks.

Winterization & Protection

  • Antifreeze: Non-toxic, propylene glycol-based RV antifreeze for safe winter storage.

  • Water Pressure Regulators: Essential protection to prevent high-pressure campground water from bursting your pipes.

  • Bypass Kits: Valves and tubing to bypass your water heater during winterization, saving you gallons of antifreeze.

Why Not Use Residential Parts?

While some parts are interchangeable, many are not. RV plumbing uses lightweight materials to save fuel and flexible lines (like PEX) to handle earthquake-level vibration while towing. Standard residential toilets require a tank (RVs do not), and home faucets often have different connection types. Using RV-specific parts ensures a leak-free fit.
