Pressure Washer Pumps

[aggie82josh]

I have one of those Troy Built 2,700 psi pressure washers from Home Depot. Well, the pump went out on it this weekend. So, I’m going to have to replace it. I noticed for a few more dollars they have a 3,100 psi pump. Anyone know if upsizing to the 3,100 would be a problem? Or should I just stick with the 2,700 psi pump?

Will it fit using the same mounting holes??

Following. Ive got the same pressure washer with the same pump issue. Was debating on just buying another pressure washer.

Fitting and being able to drive it are two different issues. Usually get a 10-15cc displacement bump when jumping between pump sizes. I'd be more interested in finding a quality (aftermarket) unit vs trying to go up in size.

I just bought one so my head is crammed with random powerwasher facts.

are you sure your pump is out or frozen up a little. With my Dewalt I lieft it outside for a short time and rust froze up the pump. I got some WD 40 Corrosion and sprayes it in there real good and it been working fine every since.

I had a Craftsman pressure washer do the same. I called to get a new pump,you can get a new pressure washer for about the same.Didn't realize the pumps cost so much.Might check into this.

This was my experience as well. The pump was going to cost the same or more than buying a new one. I found out mine was still under warranty so it worked out. Where did you find the replacement pump?

Have you checked the jets? Pull them apart, push them loose with a tiny screwdriver if stuck, then grease/lube them and reinstall. Happens especially if you have hard water. If they are stuck, you wont get any pressure, maybe a little stream...

So what exactly is the problem? As i said before its worth it to try and clean them before buying a new pump. If you do, cat pumps are really good.

I can fire up the motor but, when I try to spray with the wand, the pump doesn't engage. I get the same little spray as when just the water hose is on with the engine turned off. I guess I'll take the pump off and play with it some before I buy another pump.

For the guys that say a replacement pump the same as a new pressure washer, I did some quick searching on the internet and found a bunch of 2,700 psi pumps for under $100. Considerable cheaper than a new pressure washer. The pump swap seams like a pretty straight forward swap.


I guess I'll stick with a 2,700 psi pump. No need in burning up the motor for a little more spray

Soak it in WD 40 Corrosion . Mine was doing the same thing you are describing and the WD 40 fixed it.

Yes im betting you have one or two of the jets stuck, pumps really don't fail all that often. Im guessing you have three jets, so unscrew the caps (watch out they're under pressure by a spring, so hold them) and the little jets will be in there and they're stuck so just push it down and youll feel it "unstick". Its really straight forward and youll see what im talking bout when you take off the caps. Takes all of 5 minutes to do. Just did mine not to long ago, same symptoms your having. No need to take the pump off, just pull them break free and grease. When you look at your pump, the cast brass piece on the side of it is where they are located, as i said, just unscrew the caps on top.
