Power washer pump oil change.

[dodge man]

I thought to look at the sight glass on my pressure washer pump and it had enough but looked milky. Sure enough it was. It’s probably about 15 years old and I’m guessing I’ve changed it once at the most. The manual says every so many hours or every 3 months. I’m not going to change it every 3 months but I need to do it more often. It’s a Simpson power washer..

Eww. That’s nasty. Maybe after changing it, run it for a half hour and change it again.

That’s my plan.

That’s my plan.

Good idea . . .

Almost all of us has some piece of equipment that gets overlooked!
Who's perfect?
Good Luck!

I change mine every year.

I think I better check mine out, I’m way overdue to change it.

I changed it again, it still looked contaminated, maybe not as bad. Is there some kind of seal or gasket that might be bad that allows water into the oil side of the pump? I’ve never had one apart. It wasn’t overfilled when I changed it the first time.

I change all of my pressure washers oil quarterly but they will run 8-10 hours a day, 5 days a week at times. Sound like you have some leaking seals or bad plunger. I would check into that. If you aren't running a bypass system on it, I would look into adding one. Heat is the killer on these machines so you need a constant flow of water even when OFF the trigger.
