Compared to a NorthStar complete washer, it does come with the unloader valve but not with the electric cut-out switch and relay. I was able to locate this online. Unit works just like the previously purchased 2 hp electric washer now.

i have 1.5hp 5/8 shaft will this pump work ?
1 answer-
ProductExpert13· 16 years ago
While this pump is made to work with a 5/8 shaft engine, it requires 2 horsepower to achieve the full 1.5 gallons per minute and 2000 psi. It may work with your engine however it may not perform as well as it would with the full 2hp.
