05 Feb RV Plumbing isn’t that much not the same as a house type plumbing system that is traditional.
But, the RV that is generic diagram below can help clean up a few problems.
You need an actual RV Water schematic for your particular model, best to contact the manufacturer directly if you find.
Fresh water for the RV can be had 2 other ways. It goes directly into the various lines within your RV and feeds water directly if you are hooked up to city water. We highly encourage at the least a water filter that is basic. It's going to keep tiny debris out of the water pump - it is made to pump water - maybe perhaps perhaps not debris!
If you're NOT hooked as much as town water, the new water tank needs to be filled to keep fresh water for you personally.
Then whenever you turn your tap on, water shall turn out! Between the water that is fresh as well as your different water outlets should be a 12 Volt DC Water Pump that pulls water from your own tank and pressurizes your water lines - the same as town water.
This water pump may have an on/off change to begin things.
