Hi I was looking at some of your pump parts on eBay, I have a Stenner chlorine injector on my water well,but it has stop injecting the chlorine, the pump motor turns fine, all the lines are good, I changed the duck bill valve but still will not work. My question is, do the tubes in the pump go bad, because mine looks fine but I don't know what else to change. Any help will be appreciated.
Thanks jay
