Pressure washer leak

Posted by biglumber (My Page) on

Have a 3100 psi 2.8 gal or so dewalt pressure washer. Nice cat pump started leaking oil. Water pressure seems fine. Any ideas? The leak seams to be coming from under or behind the triplex where it connects to the housing.
I do not believe there was a freeze but I think my son put it away wet a couple of weeks ago. The unit does stay in the garage.

RE: Pressure washer leak

If you live in cold climes, it would be best to store it inside a warm place. All it takes to freeze and crack the pump, is some small amount of un-drained water and 30 degrees! Also, there is probably an oil seal that has become worn, and now leaks. Caused by long storage, and little use, mostly.

Did you ever run it w/o a running water supply?

Going to have to pinpoint the leak to see if it's a flange, gasket, or housing cracked. Once you figure out whats leaking you can take the apporate action. (buy or make gasket, RTV, or JB weld)?
