In the last two days I have had to replace the viton seal in my ace 304 sprayer pump. As far as I know, I have not run the pump dry--at least for sure that wasn't the problem the second time. My solution has Degree, Aatrex, Silencer, and Panhandler soil conditioner. What things could cause this? Any tricks to the install that I may be messing up?
