HA!!
I just as soon put a prop on the motor and get me a parachute.
So the piston pump is a lesser of a pump? I see you have a 3 gallon model 473 that would about serve me good for a round of spraying. I know it's best to not leave any liquids sit, so 3 gallons would work out good. However, it's a piston type pump. Can all the piston pump sprayers be converted to diaphram?
but then the 475 is a 4 gallon and is already a diaphram.

yea but for an extra $3 you might as well get the 4 gallon diaphram pump to keep from have to spend $30 on the diaphram conversion kit. you can only mix 3 gallons if thats how much you think you will use. Im just brain storming.

yeah I went back and looked and noticed I had the wrong model number mentioned. Then I noticed the 475 isn't much more and already disphram.
