    Sanitizing fresh water tank

    We have the Nautilus P1 control system in our 2017 Grand Design Reflection 5th wheel. It has a 60 gallon tank, if that matters. I have looked at the manual for the P1 system and I think it's missing a step. It gives instructions for using the fresh water hose to siphon the sanitizing solution (bleach) from a bucket. It then says to fill up the tank. Does that mean that I take the end of the hose I have been siphoning from in the bucket and reattaching it to the spigot (city water) to fill it?

    That is essentially correct. Use a short section of hose (I cut a 3' section of old hose to winterize and use this) to siphon the solution into the tank. I then hook up the fresh water hose to the tap at the house and fill the tank. I then run water using the pump through all of the fixtures in the trailer to get the entire system sanitized.

    And then how long do you leave it in the lines to sanitize? Overnight? Couple hours?

    I don't have an old hose I can cut. Can I use the same hose I use to go from the city line?

    If you are talking about your regular supply hose (25' or 50'), you could but the pump probably will not have a enough suction to pull the sanitizing solution that far. A short hose and keeping the bucket up high (I sit mine in the pass through compartment) would work the best. This applies to both sanitizing and winterizing (syphoning anti-freeze) if applicable.

    PS A 4' hookup hose (this is what I use) is only $6.29 at Camping World. Lots of places to buy one.

    I leave it sit for about 6 hours and then drain and rinse. If I use a stronger solution of sanitizer I can leave it sit for less time. If you do a search on the internet it will tell you how long for the strength of the solution.

    You can pour your cup of bleach into your water hose, then attach and fill your tank the usual way.

    I do this as well but I use pool chlorine granuals. Based on the % chlorine in the granuals I measure out the amount put it into the hose and fill the tank. I have verified the strength this wasy with a pool test kit the first couple of times to make sure I had it correct.
