Pump Repair: Primary Diagnosis

So, your pressure washer pump is not working right and you’ve decided to fix it. Awesome! Let’s talk about how to diagnose the issue.

First, note exactly what is happening. I’m going to guess that you’ve lost pressure. But how much? Is it a partial loss (still have some pressure),total loss (same as if there was no pump), or a complete loss of water flow (no water at all is coming out of the spray gun).

So how do you figure that out? Crank up the pressure washer and pull the trigger. Note the water flow. Now turn off the engine and pull the trigger. What is the difference? If there is no difference, there is a complete loss of pressure from the pump. If there is a difference, then you only have a partial loss.

Why is this important? Well, these different scenarios mean different things are wrong with the pump. We will get into each one in future posts.

Now, you may also note other things wrong. Maybe there are some funny noises, vibrations, pulses, or the like going on. That will indicate other issues as well.

We will try to cover those things in the future. But for now, give us a call if you have questions.

Pump Repair: Yes You Can!

If your pressure washer pump is not performing as it should, don’t be afraid of repairing it.

First off, if it’s not working you can’t make it worse! Right? So don’t worry about that.

Second, most decent pressure washer pumps are made to be repaired. Parts are available and there is usually easy access to the working parts of the pumps. Now, notice I said ‘decent pressure washer pumps’. The cheaper the pump (or pressure washer) the less likely that parts are available or that the pump can even be repaired. Look for brands on the pump [Annovi Reverberi (AR), CAT Pumps, General Pumps], those are easy to find parts for and repair. There are cheap gas powered pumps that are better off being replaced (Devilbiss comes to mind, or any no name pump). Sames goes for electric pumps, but they are even more sketchy at the cheaper prices.

Third, there are only so many things that can go wrong on one of these pumps. They aren’t that complex. So don’t get overwhelmed. It’s not bad.

So much for the inspirational talk. Let’s get to work on those pumps!

Pressure Washer Pump: Repair It or Replace it?

So, your pressure washer pump is broken. What do you do now?

Your first decision is do I repair it or replace it?

Replace It
Pros
1. Saves time: install the pump and you are off
2. No more repairs for a few years: it’s new, so it should last
3. Old pump can be used for parts: put the old pump on a shelf; use it for parts when the new pump has problems

Cons
1. Costs more, lots more: a new pump cost way more than parts
2. Still a time commitment: remember, you still have to transfer the hose connections, add oil, and other jobs before you are ready to use the washer again

Repair It
Pros
1. Save money: parts are way cheaper than a new pump
2. Investment in the future: hey you just learned to repair a pump! You’ll know what to do if it happens again

Cons
1. Takes time: it will take time to figure out what is wrong
2. No guarantee: you may make the repair, but it may not have been the issue with the pump. Now you have to spend more time figuring it out.

Once you figure out to repair or replace the pump, let us know. We can help.

Pump Repair: Is it Really the Pump?

This is the first in a series of pressure washer pump repair articles. The first few will be general in nature, then I’ll work on getting more specific in future posts.

When looking at repairing a pressure washer pump, the first thing to do is make sure it’s the pump that’s not working correctly. I know, sounds silly. But it can be easy to guess it’s the pump, because the motor is running fine. So it’s gotta be the pump, right? Maybe.

Sometimes where there is a loss of pressure on a pressure washer, it can be the hose/gun/wand assembly causing the issue. So, the easiest thing to do is remove it all from the pump (not while it’s running). Shut down the washer and disconnect the hose from the pressure washer. Crank it up. Is water shooting out of the pump or just trickling out?  Shut it down.

If it’s shooting out, there may be an issue with the hose/gun/wand. Look for kinks or blockages throughout that system.

If it’s trickling out, then you have a pump problem. Sometimes it’s between trickling and shooting out. Well, that’s a pump problem as well.

We will look at diagnosing pump problems in future posts in this series.
