When it comes time to dump and fill your RV’s freshwater tank, you might be wondering how to do it. Here are the steps necessary to properly drain and fill your RV’s freshwater tank:

Locate The Freshwater Tank

Finding your RV’s fresh water tank can be a little tricky, but it’s not impossible. Once you know where it is, dumping and filling it is a breeze. The freshwater tank is usually located near the back of the vehicle, on either the left or right side. It will be either partially or fully hidden behind a cabinet door or panel.

If you’re having trouble finding it, consult your RV’s owner’s manual or ask a fellow RVer. Once you’ve located the fresh water tank, it’s time to get started on draining it.

Draining The Freshwater Tank

The first step is to open all the faucets in your RV – both hot and cold – to allow the water to start flowing out. Next, locate the fresh water tank’s drain valve. This is usually located near the bottom of the tank, on either the front or rear side. Once you’ve found it, open the valve by turning it counterclockwise until it stops.

Now, all that’s left to do is wait for the water to finish draining out of the tank. This usually takes between 30 minutes and an hour, depending on the size of your freshwater tank.

Once the tank is empty, close all the faucets in your RV and turn off the freshwater pump. Then, open the drain valve again to allow any remaining water in the lines to drain out. Close the valve when finished.

Congratulations! You’ve now successfully drained your RV’s freshwater tank. Now it’s time to fill it back up again.

Filling The Freshwater Tank

The process of filling your RV’s fresh water tank is pretty simple. Just attach a hose to a water source – like a spigot or water hookup – and turn it on. Then, open the fill valve (located near the top of the tank) and let the water flow in.

Once the tank is full, close the fill valve and disconnect the hose. That’s all there is to it! Just remember to turn on your RV’s freshwater pump before using any water from the tank.

And there you have it! A complete guide to draining and filling your RV’s freshwater tank. Now you’ll be able to do it with confidence, knowing that you’re doing it the right way.

RVing is a great way to see the country and experience different parts of the US, but it can also be a great way to save money on your travel expenses. One area where you can save money while RVing is by conserving freshwater. Here are some tips on how to do this:

  • Fill up your fresh water tank at a discount: Many campgrounds and RV parks offer discounts for filling up your freshwater tank. This can save you money on your overall camping expenses.
  • Use gray water for plants: Gray water is the wastewater from showers, sinks, and washing dishes. This water can be used to water plants or gardens. This is a great way to conserve freshwater while also fertilizing your plants.
  • Use a solar shower: Solar showers are a great way to conserve freshwater while still getting clean. These showers use the sun’s energy to heat up water, so you don’t have to use any freshwater to take a shower.
  • Collect rainwater: If you are parked in an area where it rains frequently, you can collect rainwater to use for various purposes. This is a great way to get free water for your RV.

These are just a few tips on how to conserve freshwater while RVing. By following these tips, you can save money on your overall camping expenses.
