Is it Safe to Use a Pressure Washer Hose After a Car Runs It Over?

Running over a pressure washer hose with a vehicle is a common job-site accident. That doesn't mean it should be ignored—a damaged hose can lead to catastrophic equipment failure.

It's a mistake that could require stitches. Seriously.

Whether it's a small car or a heavy truck, knowing how to identify and repair a damaged pressure washer hose is critical for maintaining site safety and keeping downtime to a minimum.

What if A Car Runs Over My Hose?

If a vehicle runs over a high-pressure hose, inspect it immediately. Any signs of flat spots, exposed wire braiding, or bulging mean the hose is compromised. If your dealer offers a hose repair service, you can save some money...

But we don't recommend it. And many dealers don't even offer it.

Why?

A repaired hose always runs the risk of bursting at the repair spot. If you're lucky, you might not get hurt. But many of us haven't been so lucky. Blowback from a burst hose can hit hard, and the high-pressure stream of water can be as damaging as a red tip.

That's why in our professional experience, it's best to replace it entirely. We recommend a 2-wire hose for better durability and crush resistance. These hoses have 2 layers of wire braiding, so not only are they more durable (and therefore last longer), they are rated for higher pressures. 6,000 PSI is standard.

If your hose was run over or damaged in any way, and you want a professional opinion on how much more life it has, your local dealer expert can take a look.

How To Inspect Your Pressure Washer Hose for Damage

Before turning the pressure back on, perform a physical inspection. Here are the 3 things we look for as indicators that a hose is no longer safe for service:

• Flat Spots and Distortion: Look for "squashed" areas. A flat spot creates a permanent weak point in the internal structure that will eventually fail under pressure.

• Exposed Wire Braiding: Pressure washer hoses are "drag items" that wear down on concrete. If a vehicle tire has scuffed away the outer jacket to reveal the steel braiding, the hose must be replaced immediately. If you can see the braiding, there isn't much support left to keep YOU from getting cut with a pencil stream of water.

• Bubbles and Bulging: A bulge indicates the internal tube has leaked into the braiding. If you spot this, it's done. It's only time until it leads to a violent burst.

Should You Repair or Replace a High-Pressure Hose?

Many operators ask whether they can repair a hose to save costs. While repair kits exist, we believe that replacement is the only way to be confident that a hose rupture isn't creeping around the corner.

If the cost of a new hose isn't in the cards, NEVER attempt a repair without the proper equipment or knowledge. Take it to a professional. High PSI water does NOT play nice with human flesh.

1. Technical Complexity: Repairing a hose requires specialized hydraulic crimping tools. Standard "DIY" clamps cannot safely hold the thousands of PSI generated by your pressure washer.

2. Rating Mismatches: Replacement fittings may not match the GPM or PSI rating of the machine. Since there are different tolerances between hose manufacturers, the security of the fitting may not be as solid as is necessary for a repair like this.

3. Again: Operator Safety!: A bursting hose can cause severe whip injuries, cuts from the stream, or high-temperature burns. The cost of a new high-pressure hose is significantly lower than the cost of a hospital visit.

Make Your Hose Last As Long As Possible

To maximize the life of our equipment and prevent job-site accidents, keep this in mind:

• Inspect During Cleanup: Every time the hose is coiled, run a gloved hand along the length to feel for nicks, flat spots, or internal structural deformities.

• Protect Your Hose: Consider using a cable ramp if the site requires operating in areas with vehicle traffic. Don't trust the intelligence of strangers; if someone can run over it, eventually, someone will.

Summary

A pressure washer hose that has been run over should always be inspected immediately, and a compromised hose should be replaced.
