Nigel. For years and years I've been using everything from Sureflows to Flowjets and everything in between for Roof Cleaning and for spraying concrete etc...They just don't last for me. I take good care of my stuff but dealing with 12.5 % will eventually eat up just about anything. I'm still using a Delavan to spray concrete and to transfer chems but I was over the problems I was having with 12volt pumps breaking down all the time. The Air Flo pump that I have switched to is an air driven double diaphragm pump and made out of Kynar which will hold up to the love sooo much better than any 12 volt system. Here is a link to All Flow pumps. I hope this helps a little.Thank You.
Larry what were you using before the diaphram pump?
Pros and cons of the both?
