I am really hoping you guys can help me out. I run Bean pumps and they have been great, except for one issue - our chemlawn gun yellow nozzles will get clogged with debris of some sort in a matter of minutes when using. We have cleaned the fiberglass tank to the point you could eat off of it, We have totally removed the Bean filter and housing, and replaced with 50 mesh Banjo setup, We have flushed many gallons of water through the tank/pump hoping to get whatever the debris is, out of the system, but we are still having problems. The Bean setup has the filter on the vacuum side of the pump, but I want to install a filter just before the hose to make certain that nothing can possibly get to the nozzle. Is this possible? What system do I need? Have any of you had this problem? I was under the impression that Bean is the best, but being cast iron, it flakes and rusts a great amount. Any help is much appreciated, Thank you.
