The Importance of Reliable Plumbing for Pressure Washer Trailers

A consistent water flow is essential for performance, reliability, and protecting your investment in the long run. Learning how to plumb a pressure washer trailer properly ensures the efficiency and safety of your equipment.

Ensuring Efficiency and Performance

Inconsistent water flow can cause fluctuations in pressure and compromise cleaning effectiveness. Reliable plumbing delivers a consistent water supply to enable your pressure washer to operate at peak performance. Whether you are tackling large commercial jobs or smaller residential tasks this helps achieve thorough and efficient cleaning.

Avoiding Downtime

Leaks, blockages, and other plumbing issues can cut into productivity. Downtime can be costly for commercial and industrial applications. When water isn’t flowing correctly, it can lead to missed deadlines, which could have serious consequences for your reputation as well.

Reliable plumbing minimizes these risks by providing secure connections and reducing the chance of disruptions. This reduces the likelihood of emergency repairs, allowing you to maintain a steady workflow and meet your clients’ expectations. 

You won’t have to waste your time learning how to repair pressure washer if you do it right the first time around! Similarly, you won’t have to stress about the pressure washer repair cost.

Safety Considerations

Safety is always the top priority in commercial settings, but improper plumbing can create slippery surfaces that pose slip-and-fall hazards. 

Moreover, water leaks can lead to more serious issues if they come into contact with electrical components. Reliable plumbing prevents these risks by ensuring all connections are secure and leak-free. 

Protecting Equipment

Speaking of water leaks causing problems, these same issues can create rust, corrosion, and other forms of damage that shorten the lifespan of your equipment. 

Reliable plumbing safeguards your investment by preventing leaks and ensuring that water flows only where it is supposed to. 

How to Plumb a Pressure Washer Trailer: Step-by-Step Guide

It’s important that you are realistic with yourself about whether you have the ability to actually plumb your own pressure washer trailer or not. 

Most of the time it’s not worth the risks if you aren’t an experienced plumber. Save yourself the time and stress by partnering with the pros here at RJP Hotsy, where you can purchase your own trailer or even consider industrial pressure washer leasing NJ or industrial pressure washer rental NJ.

But, if you’re committed to learning how to plumb a pressure washer trailer yourself, here’s an overview of the process.

Use a Pressure Washer Trailer Plumbing Diagram to Plan

The hardest part of plumbing a pressure washing trailer is how complex it can get with so many different moving parts. That’s why using a pressure washer trailer plumbing diagram is a great idea.

This will help you visualize the layout and ensure all components are correctly positioned and connected. Here’s a brief overview of creating your own diagram to simplify this task:

  • Create a Custom Diagram: Sketch your trailer layout, including the placement of the water tank, pressure washer pump, hoses, and fittings. It needs to include all necessary components such as filters, valves, and connectors.
  • Identify Key Components: Highlight the most important parts like the water inlet, outlet, pump, and chemical injector. This helps visualize the flow of water through the system.
  • Plan the Hose Routes: Determine the optimal routes for hoses to minimize kinks and ensure smooth water flow. Mark where the hoses will connect to the tank, pump, and pressure washer.

Installing the Water Tank

If you haven’t already installed the water tank on your trailer, now is the time to do so. Place it in a secure location on the trailer and make sure it’s stable and well-supported to prevent movement during transport.

You will need to use mounting brackets or straps to secure the tank to the trailer bed. Make sure it is firmly attached to avoid any vibrations or shifting. Then, attach a ¾” ID water supply hose to the tank’s inlet. Ensure a tight connection using hose clamps to prevent leaks.

We recommend you install a high-temperature Hudson float valve to regulate the water level in the tank. This will automatically shut off the water supply when the tank is full to prevent overflows.

Connecting the Pressure Washer

Now you’ll need to get the pressure washer secured and connected to the water tank, as this will facilitate ample water supply to your unit.

Use a 1” non-collapsible suction hose to connect the water tank outlet to the pressure washer pump inlet. Secure the connection with hose clamps. 

Then, place a 1.5” Y strainer filter between the tank and pump to catch any debris and prevent it from entering the pump. This is important for pump longevity.

Attach a high-pressure hose to the pump outlet. Ensure the hose is rated for high-pressure use and secure the connection with appropriate fittings.

Install an unloader valve on the pump to help manage the water pressure and flow, preventing damage to the pump during operation.

Plumbing the Drain and Overflow Systems

While these can be easy to overlook as part of the process, effective drainage and overflow systems are essential for maintaining a clean and efficient pressure washer trailer.

Install a drain valve at the lowest point of the water tank to facilitate easy drainage of the tank when not in use or for maintenance purposes.

Connect an overflow hose to the tank’s overflow outlet. It should direct excess water away from the trailer, preventing any potential damage or safety hazards.

Make sure all connections for the drain and overflow systems are secure and leak-free. Use high-quality fittings and clamps to maintain a reliable setup.

Securing and Testing the Plumbing

Most of the hard work is done at this point – you just need to secure and test the entire plumbing system to catch any leaks before you actually head out to your first cleaning job.

Use hose clamps and brackets to secure all hoses and fittings. Ensure that hoses are routed in a way that prevents kinks and reduces wear and tear.

You’ll want to perform a pressure test on the system. Fill the tank with water and run the pressure washer at full capacity to check for leaks and ensure proper water flow.

Set the unloader valve to the correct pressure setting as specified by the pressure washer manufacturer to keep the system operating within safe pressure limits.
