How to sanitize fresh water system on 2015 Berkshire XL?

[mike.t]

I have read a lot of people like the GEO method.

Mike the GEO method is for your black tank and not to be used in your fresh water tank. Bleach or a food safe sanitizer is all that should go in the fresh tank.

So once the fresh water tank is filled then how do you drain it?

I believe it works in both tanks. The Ingredients are different. Google it.

Most RV's have drain tubes. However not sure about Roo's.

I see a group of 2 rubber tubes hanging down, but I don't see how you turn on the water to drain.

Mike to make my last pit clear it is for the black tank and the gray tank. I have never heard and would not recommend using in the fresh water tank. Bleach is what will sanitize the tank. You don't use the geo method in your fresh water tank do you?

Does one have a cap on it?
If so remove it.

I use the bleach per gallon for the fresh water. Sorry for the confusion. I was referring to the grey tank not the fresh water.

[Phil57]

No problem. I just wanted to make sure no one added soap to their fresh tank.

Pour bleach into the hose and be done with it. Too complicated any other way. Less stress. )

I have a separate filter housing with the filter removed, that I attach to the water faucet. I put bleach into the filter housing, and attach a white fresh water hose to the output side of the housing. The white water hose is connected to the fresh water input coupling on the RV. When I turn the water on, the fresh water hose gets cleaned by the bleach water while it is filling the fresh water tank in the RV with bleach water. After sitting overnight, I drain the fresh water tank and rinse out with clean non-bleach water.
