Common Causes Of Leaks

A pressure washer pump is the heart of your cleaning machine, but sometimes it can start leaking. Leaks can turn a powerful stream into a weak dribble and make cleaning tasks harder. Let’s explore the common causes of leaks and how to fix them.

 

Worn Seals

One of the top reasons for a leaking pump is worn seals. Over time, the seals that keep the water inside the pump can wear out. This can happen from normal use or from the pump running dry. Here’s what to look out for:

  • Water dripping from the pump when it’s not running
  • A drop in pressure when using the washer
  • Visible damage or wear on the seals

 

If you notice these signs, it’s time to check the seals. You’ll need to:

  1. Turn off the pressure washer and disconnect it from power.
  2. Release any pressure by squeezing the trigger on the spray gun.
  3. Remove the pump from the washer to check the seals.

 

Here’s a simple table to help you understand the types of seals and their functions:

Type of Seal Function Signs of Wear
O-rings Seal connections between parts Flattening, cracks, or breaks
Water seals Keep the water inside the pump Thinning or tearing
Valve seals Prevent water from leaking out of valves Hardening or shrinking

Replace any damaged seals with new ones. Make sure they fit snugly and are the right size for your pump.

 

Cracked Housing

Cracked housing is another common cause of leaks in pressure washer pumps. The pump housing can crack due to:

  • Impact or accidental drops
  • Freezing temperatures that cause the water inside to expand
  • Manufacturing defects or material fatigue

 

To fix cracked housing, follow these steps:

  1. Examine the pump housing closely for any cracks.
  2. If you find a crack, assess whether it’s small enough to repair or if the housing needs replacing.
  3. For small cracks, a strong, waterproof adhesive may work as a temporary fix.
  4. For larger cracks, you’ll need to replace the entire pump housing.

Remember, working with high-pressure systems can be dangerous. Always wear safety gear and consult your pressure washer’s manual before attempting repairs. If you’re unsure, it’s best to seek help from a professional.
