The system was built in Othello, WA in the early 1990s. It has a Briggs and Stratton 5hp pump at 10 GPM that was professionally rebuilt in ~2016. It has a brass jet with a wide spray that can be turned off and on inside the vehicle. It sits on a rolling cart for easier loading and unloading. It is in good working condition and has always been stored undercover when not in use. Delivery is available and negotiable pending distance. It's best to call if you have questions.
