LippertPart 20211339401-Year WarrantyLippert Power Pro Max Pressure Washer Garden Hose Adapter

Stop relying on the onboard tank. The Lippert 2021133940 Hose Adapter plugs your Power Pro Max portable pressure washer directly into any standard garden hose, giving you a continuous water supply for washing your RV, tow vehicle, slides, awnings, or campsite gear -- no refilling required.

Keep the Water Flowing Without Stopping to Refill

The Power Pro Max is a capable portable pressure washer built for RV owners who need washing power on the road or at the campsite. Its onboard tank works well for quick jobs, but for bigger tasks -- a full RV rinse, a muddy tow vehicle, or a thorough slide-out scrub -- you want an uninterrupted water source.

This OEM adapter is the direct solution. It threads onto a standard garden hose and mates to the inlet port of the Power Pro Max, converting the unit to a continuous-flow configuration. The connection is designed to be leak-free at the joint, so you get full pressure at the nozzle rather than losing flow to a dripping fitting.

Garden Hose Ready

Connects directly to any standard garden hose fitting -- no extra tools or adapters needed for typical campground water connections.

Continuous Supply

Eliminates the need to stop and refill the onboard reservoir, letting you tackle larger wash jobs from start to finish.

Leak-Free Design

Engineered to form a secure, drip-free seal at the hose connection so full water pressure reaches the pump inlet.

Lightweight

Weighs only 0.05 lbs., so it adds virtually nothing to your accessory kit. Easy to store in any small compartment or bag.

Typical Use Cases for RV Owners

At full hookup sites, this adapter lets you run the Power Pro Max directly off the campground water pedestal via your garden hose. That means:

  • Full exterior RV wash without moving water or hauling buckets
  • Rinsing tow vehicles, ATVs, bikes, or boats after dusty or muddy trips
  • Cleaning slide-out seals, awning fabric, and underbelly areas
  • Watering plants or rinsing campsite equipment with low-pressure hose flow when the pressure washer is not in use
Continuous Flow Advantage: When fed by a garden hose, the Power Pro Max is no longer limited by tank volume. For RVs with heavy exterior dirt buildup after highway miles or off-road access roads, this adapter makes the difference between a partial rinse and a thorough clean.

Installation Overview

Connection is straightforward. Thread the adapter onto your garden hose, then attach the other end to the water inlet port on your Power Pro Max unit. Hand-tighten to form the seal -- no pipe tape or tools required for standard connections. Turn on the hose supply before powering on the pressure washer to prime the pump.

Priming Tip: Always open the garden hose supply valve fully before switching the Power Pro Max on. Running the pump dry -- even briefly -- can shorten pump life. The garden hose connection ensures the pump stays primed throughout the wash cycle.
Compatibility Notice: This adapter is designed exclusively for the Lippert Power Pro Max portable pressure washer. It is NOT a universal pressure washer fitting and is not confirmed to fit other Lippert wash products or third-party units. Verify your unit is the Power Pro Max before ordering.
Storage Tip: After use, disconnect the adapter, drain any standing water, and store dry. Even at 0.05 lbs., the fitting is easy to misplace -- keep it with your Power Pro Max accessory bag so it is always ready at the next campsite.

Important Information
  • This adapter is ONLY compatible with the Lippert Power Pro Max portable pressure washer. Do not attempt to use with other pressure washer brands or models.
  • Always open the garden hose water supply fully before powering on the Power Pro Max to avoid dry-running the pump.
  • Inspect the adapter for cracks or damage before each use. A compromised fitting can cause leaks at the inlet and reduce pump performance.
  • Do not exceed the water pressure rating of the Power Pro Max inlet when connecting to high-pressure campground water sources -- use a regulator if site pressure is above 60 PSI.
  • Store dry after each use to prevent mineral buildup or freeze damage in cold climates.
