    Just got our first dedicated spray truck. Found it somewhat locally on craigslist and bought it because it was a fantastic deal. The truck alone was worth more than paid. It has two Oldham 200 gallon tanks, Honda motor, pump, and two reels. One is a manual reel with a smaller hose for trees and ornamentals while the other is powered with the turf hose.

    Here are my questions:
    The pickup on the tanks is on the side with a PVC pipe straight down about 1/2" from the bottom of the tanks. The problem is, I can't get the tanks completely empty. They are also pretty dirty inside although the guy I bought it from said he put tank cleaner in it. Do you guys have a drain on yours? If so, what should I get?

    There are no agitators. Again, what do I need to buy to add these?

    Is there anything else I need to get? I'd like to get this thing ready to go for the first round of pre.

    Re do the pick up tube so it goes completely down to the bottom. The end of the pick up should have small notches cut into the end so even if it touching bottom, it is not dead ended. I use the Hypro jet agitation nozzles fitted with DCER-6 discs. These are ceramic discs instead of the usual plastic or steel, so no rust and a long wear life. Those are mounted on a tee at the end of a down pipe bulk headed into the tank. The agitation line is tapped off of the high pressure line feeding the hose reel. Do not take the agitation from the bypass off of the pressure regulator if you are running a plunger or diaphragm pump. You also do not do this to a roller pump either.

    Its tough to get that last ounce or two out of the tank. You seldom need to get it completely dry, luckily. Some kind of hand pump or bilge pump should work for that problem. You may want to use a high-pressure power washer if you need to remove some kind of sticky residue. When pumping out...be sure to park the truck on the steepest part of your drive or a steep hill...to get the water to flow to where you can get at it.

    In my case I used my sprayer with a Hypro diaphragm pump for many years with the agitation connected to the pressure regulator bypass hose. When not spraying, all flow from the pump goes to the agitation nozzles. I used a section of poly tubing to go from the top inside of the tank to carry the agitation flow to the bottom. A plastic pipe tee then allowed me to add four Delavan agitation nozzles. They were aimed to provide the maximum swirling and rotation of the spray solution.
