Rated 3 out of 5 by from Increasingly not happy! This is my third unit from Generac. The first one was used for 4 years and had 5000 hours on it. The second one was defective right out of the box and cost me 3 weeks of down time for my business. Now it has gas in the oil and needs to be repaired. I ordered a third one and just received it. It is missing a vented cap on the water pump. I can only get the part from a Generac Dealer who will order it from Generac and cost me more lost time while I wait for it, because Generac won't supply it to me.

Rated 1 out of 5 by from Pump went out with less then 3 hours of use I purchased this product for home use. The pump went out with less then 3 hours of use. I took the pressure washer to the authorized service center and was told Generac only warrantied their pumps for one year and my receipt was from 1 year 2 days.
