Storage (continued)
Sanitize your potable water system.
1. Determine the size of your water system, the potable water
holding tank, plus the hot water tank and two to three gallons for
your water lines, depending on your set up. Refer to your owner's
manual.
2. Prepare a 5% sodium-hypochlorite solution using chlorine bleach
(non-scented and non-gel) and water. Use the chart below for mix
concentrations.
Fresh Water Tank
Size
40 gallons (152 liters)
50 gallons (190 liters)
60 gallons (227 liters)
80 gallons (302 liters)
100 gallons (380 liters)
Add bleach mixture to the water tank – NEVER POUR
3.
STRAIGHT BLEACH INTO THE FRESH WATER TANK!
4. If you have a bypass for your hot water tank, make sure that is set
for normal use so that the bleach mixture will be pumped through
the hot water tank.
5. Top off the potable water tank with potable water.
6. Run the chlorinated water through all lines (hot and cold, one at a
time) for one to two minutes. You should be able to smell the
chlorine.
7. Top off the potable water tank again.
8. Let it sit for 4 hours minimum; overnight is best. The most
important thing is to wait the appropriate amount of time for the
tank to be properly sanitized.
NOTE: Doubling the bleach will not cut the time in half! Drain and rinse the
potable water tank and water lines several times with fresh, potable water.
The water should now be safe to drink, but if the chlorine odor is too strong,
add a mixture of 1/2 cup baking soda and a gallon of fresh water to the
potable water tank and repeat the potable water flush.
