HOW TO SANITIZE THE FRESH TANKS, PLUMBING, AND HOT WATER TANK

This article is a copy of the procedure to sanitize the fresh water tanks, plumbing, and hot water tanks as it appears in our article - THE DEFINITIVE DEWINTERIZING AND SANITIZING - STEP BY STEP.  I have put it in its own article for those who just want to know how to sanitize the the water system in the Roadtrek. 

THIS IS WHAT YOU WILL NEED BEFORE YOU START:

Fresh Water Hose
Water Pressure Regulator
Liquid Chlorine Bleach (Clorox or off brand is fine) PLEASE NOTE: There is something called "Splash-Less" Bleach. DO NOT BUY THIS FOR SANITIZING YOUR TANKS. It does not have disinfectant properties and will not disinfect surfaces." BUY REGULAR BLEACH. (Thanks to one of our readers, "Tom" for bringing this to our attention!)
Funnel with hose on the end
Measuring Cup (for Bleach)
Small paper cups
Hot Water Tank FLUSH  Wand
Ratchet wrench handle
1-1/16" Socket
Plumbers silicone pipe tape to put on threads of the anode rod when putting it back in.

Drain and flush the hot water tank before you start.

SANITIZING THE FRESH WATER TANKS

  1. TURN HOT WATER BYPASS VALVES TO HOT WATER FLOW. 
  2. CONNECT A FRESH WATER HOSE WITH A WATER PRESSURE REGULATOR ONTO THE CITY WATER FILL CONNECTION. 
  3.  USE CITY WATER LINE TO FILL HOT WATER TANK BY RUNNING CITY WATER INTO THAT TANK. (NOT CITY WATER FILL - REGULAR USE OF CITY WATER) GO TO THE SINK, TURN ON HOT WATER AT SINK. AIR WILL COME OUT - AND THE TANK WILL FILL. WHEN IT IS FULL THE WATER WILL RUN STEADILY FROM THE FAUCET. DO NOT TURN ON HOT WATER SWITCH. THIS WILL BE COLD WATER AND THAT IS WHAT NEEDS TO BE.
  4. DISCONNECT CITY WATER CONNECT FROM HOSE.
  5. PUT ONE HALF CUP BLEACH INTO THE FRONT EXTERIOR FRESH TANK. (PRE-MIX THE BLEACH IN A GALLON JUG OF WATER BEFORE PUTTING IT INTO THE FRESH TANK - DO NOT PUT PURE BLEACH INTO THE TANK.) A FUNNEL WITH A HOSE ON THE END IS EASIEST TO GET THE BLEACH/WATER MIX INTO THE FRESH TANK THROUGH THE DOOR FILL HOLE.
  6. PUT ONE QUARTER CUP BLEACH INTO THE REAR INTERIOR FRESH TANK. (PRE-MIX THE BLEACH IN A GALLON JUG OF WATER BEFORE PUTTING IT INTO THE FRESH TANK - DO NOT PUT PURE BLEACH INTO THE TANK.) IF YOUR ROADTREK HAS ONLY ONE FRESH TANK - SKIP THIS STEP.
  7. TOP OFF WATER IN TANKS WITH HOSE.
  8. DRIVE BACK AND FORTH TO MIX THE BLEACH INTO THE WATER.
  9. TURN ON BATTERY SWITCH AND WATER PUMP.
  10. TURN ON EACH FAUCET HANDLE PLUS INSIDE AND OUTSIDE SHOWER ONE HANDLE AT A TIME SMELLING FOR BLEACH TO COME THROUGH WITH EACH. NOT THE TOILET.
  11. NOW YOU WAIT. 
  12. LET BLEACH SIT IN TANKS FOR AT LEAST FOUR HOURS. LONGER IS OK!
  13. DRAIN WATER TANKS.
  14.  NOW WE REMOVE THE BLEACH FROM THE HOT WATER TANK FIRST. 
  15.  1) The hot water tank should NOT be in bypass while sanitizing and it should remain NOT bypassed for this process. DO NOT HAVE ANY SINK FAUCET OR SHOWER FAUCET ON DURING THIS PROCESS EXCEPT WHERE AND WHEN NOTED FOR THE OUTSIDE SHOWER HOT WATER HANDLE. DO NOT TURN ON THE HOT WATER HEATER!

    2) Water pump OFF.

    3) Attach a fresh hose WITH A WATER PRESSURE REGULATOR to the city water inlet and a spigot outside. Turn on the water.

    4) Turn on the outside shower hot water handle and open fully - step back!  Only the hot water handle on the outside shower should be open. No other faucet or shower handle should be on.  As the water comes rushing out of the shower (hose optional) you should smell bleach in the water.

    5) Allow to run for at least 15 minutes. THIS WILL FILL AND  EMPTY THE TANK AT THE SAME TIME - ABOUT THREE TO FIVE TIMES.  YES THE WATER IS FLOWING DOWN THE DRIVEWAY FLUSHING THE HOT WATER TANK.

    6) After a steady flow of water for 15 minutes you should no longer smell bleach in the water coming out. (To test, take a small paper cup , slow the flow of water by turning back the handle and put the cup under the streaming water coming out. Step away from where the water has been flowing and smell the water in the paper cup. You should not smell bleach.)

    7) If you still smell bleach allow the water to continue to flow longer until there is no longer any smell of bleach in the water. (Use a new paper cup if you test again.)

    8) Shut off the hot water outside shower handle.

    9) You have now exchanged all of the water inside the 6 gallon hot water tank several times with fresh water, flushing that tank as many times.

    10) Remove the hose from the city water connection.

    11) PUT THE HOT WATER HEATER INTO BYPASS! You do not want to
    put bleach back into the hot water tank.
  16.  FILL FRESH WATER TANKS AGAIN.
  17.  GO INSIDE THE ROADTREK.
  18.  TURN ON BATTERY SWITCH AND WATER PUMP.
  19.  **TURN ON EACH FAUCET HANDLE PLUS INSIDE AND OUTSIDE SHOWER ONE HANDLE AT A TIME SMELLING FOR BLEACH TO COME THROUGH WITH EACH. NOT THE TOILET - YOU NEVER WANT ANY BLEACH TO GO INTO THE TOILET.
  20. IF YOU DO NOT SMELL BLEACH (GOOD!) SKIP TO #23
  21.  DRAIN TANKS THROUGH THE LOW POINT DRAIN.
  22.  FILL FRESH TANKS AGAIN.
  23.  IF BLEACH SMELL REPEAT FROM STEP #16 AFTER DRAINING FRESH TANKS.
  24.  DRAIN TANKS OR LEAVE FULL FOR TRIP. 
  25. PUT YOUR HOT WATER TANK OUT OF BYPASS NOW SO THAT THE TANK WILL FILL AND YOU WILL HAVE HOT WATER WHEN YOUR TANKS ARE FULL OR ARE USING CITY WATER.
