Water in pump oil

[Anthony G]

I had my pressure washer covered and heat lamped during the winter. I took the cover off the other day and test run everything before I used it in the real world. As i was testing a rain cloud came in and poured down for about an hour. When I went back out I realized the red cap on my Cat pump had broken off and there was water in the oil. I ran it for a few minutes and then changed the oil............ran it some more and I still have milk in the crankcase. What is the best way to get the rest of the water out?

Thanks,

Anthony
