Our old TT had a gravity fed inlet for the fresh tank as well as a pressurized inlet for city water. While at my campsite, I was able to add water to the fresh tank from a six gallon jug into the gravity inlet if I needed more after the original fill up. Our new 5er (five trips under our belt) has only one inlet that can be switched via valves for filling the fresh water tank or using city water. Pouring from a jug is now not an option. Obviously, I can’t add sanitizing bleach to the fresh tank with the old method either. I never realized this until I was talking with a tech at my dealership. Regarding sanitation (I do this at home), the tech did tell me to pour the proper amount of bleach into my fresh water hose with a funnel then fill the tank normally from a water spigot. The pressurized water will then force the bleach from the hose into the tank. Different, but easy enough. As for adding to the tank while at a campsite; is using a small pump the only option? Does a pump provide enough pressurization to work in this scenario? We are pretty good at conserving water and the most we stay at a site without water is four days but I want to be prepared to add water if I need it. I definitely don’t want to have to break camp to take the 5er to fill up.

Bob, I do not know your specific coach, but as a general statement, almost any pump will be able to deliver water to the potable tank from the city water connection. All that extra valve does is to by-pass the pump and (typical) check valve part of the system and go right to the tank.Matt

How do you winterize your 5th wheel? Most have a hose attached near the pump that will draw the antifreeze into the system. I have used the same hose inserted into a five gallon bucket to draw water and pump it into the tank. The trick is figuring out the settings for the valves to get it to pump into the tank.

Mine has another new inlet that I’ve never had before! There is an inlet labeled “winterization” right by the water inlet and valves and it bypasses everything to go right into the system via the on board water pump.

I’m seeing pumps around 35 PSI to 65 PSI that should work well for this process

If you can use a funnel to put bleach in your tank, why can't you use a funnel to put fresh water in from a bucket?

Buy the same or compatible pump as the RV pump and you have a backup.
