Bought this after having 3 failures with my Shurflo Extreme 5.7 pump in 4 yrs...Used in our travel trailer approx. 300 gallons a yr and nothing but problems. So read good reviews on this Jabsco V-Flo pump so I decided to give it at try....not as much pressure but not bad...only had this pump for 3 months so can't give you and long term history...nothing can be worse the the junk Shurflo Extreme...read a lot of people had problems with this pump...
