HI,WITH AN HOT WATERHEATER WITH WATER WASH 45 GALLON DRUMS PLASTIC , HOW DO YOU GET THE WVO INTO THE WATER HEATER AND WHERE DO YOU ADD THE METHANOX FOR THE REACTION TO TAKE PLACE. IS THE 45 GALLON PLASTIC DUUM USED FOR BOTH THE HOLDING BIN FOR THE WVO BEFORE IT GOES INTO THE HEATER AND THEN TRANSFEED BACK TO SETTLE OUT

Most set-ups have a a separate drum or tote for holding the WVO and then a dedicated settling and/or wash tank.
For transfering the WVO it would be easiest to use the recirculating pump attached to your appleseed. At the suction and at the discharge you would "T" off with a ball valve and a fitting for a hose to fill the appleseed and then transfer to the wash tank after processing. look at the photos in the "Processor rollcall" section and you'll see different examples of this.
