Help Sanitizing fresh water system

[rich and char]

Hi,
I'm looking for the easiest way to sanitize the fresh water system in our 36 ckts,
Our old trailer way gravity feed in to the fresh water tank. The new CC is different and now i'm not so sure. Any help would be appreciated.

Thanks
Rich

The generally accepted method of sanitizing your RV's fresh water system as outlined below involves filling the fresh water tank with a solution of household bleach and running the solution through each faucet.

Then letting it stand for at least three hours.
Finally, flush the system once or twice to remove the taste and smell.

This procedure is one you'll find in most any book about RVing it tried and true but be sure to read on to find out what I do.

Start with a nearly full fresh water tank.

Turn the water heater off and let the water cool.

Dilute 1/4 cup of household bleach for each 15 gallons of tank capacity in to a gallon of water.

Add the chlorine/water solution to the water tank. (Never pour straight bleach into the RV fresh water tank. )

One faucet at a time, let the chlorinated water run through them for one or two minutes.
You should be able to smell the chlorine.
(Make sure you are using the water pump and not an external water supply.)

Top off the RV fresh water tank and let stand for at least three hours over night is better.

Completely drain the system by flushing the faucets for several minutes each.

Open the fresh water tank drain valve to speed up emptying the tank and Open the hot water tank drain plug and drain until it is empty.

Close all valves and faucets and drain plugs.

Fill water tank with fresh water.

Flush each faucet for several minutes each repeating until the tank is again empty. (Make sure you are using the water pump and not an external water supply.)

Fill the tank again. The water should now be safe to drink but if the chlorine odor is too strong you can repeat the fresh water flush.

Your RV fresh water system should now be safe for use.

You need to use the winterization tube.
Turn off city water, open gravity valve, put about 1/2 cup of bleach in a 5 gal bucket of water and stick the tube in. You can bypass the water heater as well.

If I do like you mentioned and suck in the solution thru the winterization tube into the fresh water tank , can I fill the balance of the fresh tank with a hose connected to water supply ?

Yes. Just turn the switch back to city.
You will have to run the pump to sanitize the lines after you fill the FW tank. You can use Iggy's list from that point.
