I run a T valve and just shut off the hose from my tank and open the other valve and take that hose a drop it in a bucket with water! just remember when you go to spray a roof to swith the valves back and run it back to your tank for a bit so you dont have water come out first on the roof!
I agree w/ Eric. The T-Valve re-directing the pull from a clean water source is pretty simple and efficient. However, from understanding, most who run the All Flo dont even worry about rinsing...is that correct?
Zeke, you are correct! The All-Flo KE038-B3 was designed by All-Flo's engineers specifically for use with SH! The pump has a 5 year warranty. You do not have to rinse. However, rinsing out your pump can't hurt.
I always rinse at least 5 gal of water though the pump at the end of the day to be safe. I just rinse it back to the tank. It doesn't dilute it that much.
