However, when it comes to filling this essential piece, many people are skeptical about where to begin or how to proceed.

Not to worry! This guide will walk you through the process from beginning to end so you can get on with what’s important; enjoying the RV lifestyle on the open road without having to worry about running out of water halfway through your camping trip.

How To Refill Fresh Water Tank During Camping

The average RV fresh water tank can hold between 20 and 100 gallons of water, depending on the size and type of RV.

The number of people in your group will have an impact on how much freshwater you need to keep on hand. Because water will be in short supply if you are dry camping, you will want to be cautious with how you use it.

Here are several methods for refilling your freshwater tank while camping.

1. Refilling Your Water Tank Using A Faucet 

The most convenient way to refill your RV’s tank is to use a faucet or a water hookup to use the water pressure. Directly attach a hose to the tank and turn on the water supply until it is full.

The method you use to replenish your freshwater tanks may differ. It is dictated by the type of RV you own. You can have 2 different links for connecting to city water and filling up your tank, or you can have one single link with a nozzle.

To fill your fresh water tank with a faucet, follow these simple steps:

  • Locate a hose. When filling up your RV tank, you should only ever use a specialized RV drinking water hose. These are designed exclusively for drinking water, so they won’t add any odd flavors and are, of course, safe to use.
  • Attach the orange end of the hose to the campsite spigot or a substitute water source if you aren’t currently camping. You don’t want to come to grips with any leakages, so make sure the connection is safe and strong.
  • Twist the other end (the male end) into the appropriate RV connection. “Potable Water Only” should be written on the label. As previously stated, if you only have one input, make sure your nozzle is set to fill the fresh water tank.
  • An orange adapter can be found at the end of your drinking water hose. This is a Pressure Regulator, and it guarantees that none of the tubing inside your RV surges or rupture. Water pressure can be uncertain, so keep it on the regulator at all times to prevent harm to your RV.
  • Steadily and cautiously turn on the water spigot or faucet.
  • When your fresh water tank is full, shut off the water at the faucet and disconnect the hose from both ends.
  • Replace the lid or lid on the water intake to help ensure that no wreckage gets inside.

2. Refilling Your RV’s Fresh water tank Using A Pump

A water pump can be used to fill up your fresh water tanks. This is beneficial for prolonged dry camping trips where you might pass out of fresh water before reaching a campsite or city water hookup.

You’ll need to have an infinite container, preferably filled with fresh water. Many RVers bring a few extra jugs of fresh water with them on camping trips to prolong the amount of time they can dry camp.

To fill your fresh water tank with a pump, follow these simple steps:

  • Attach your RV’s drinking hose pipe.
  • Using alligator clips, connect a 12v pump to your car or van battery.
  • Pump water from your exterior vessel into your RV’s Fresh Water Tank, following the same steps as when you fill the tank with a hookup.

3. Refilling Your RV’s Fresh Water tank Using Gravity

This is your last option if you don’t have direct exposure to a water pump or a city water hookup.

You’ll need to use an alternative water source if you don’t have access to a suitable water channel. This could be a jug or any other external water container you brought with you to refill your fresh water supply.

To fill your freshwater tank using gravity, follow these simple steps:

  • The first thing you’ll need is water, such as a 6-gallon water jug.
  • You’ll need to figure out how to keep the source of water above the outlet hole. We suggest cautiously climbing on top of a car or ladder.
  • Simply pour the new water into the hole.
  • Attach your fresh water hose to the RV if your water jug does not have a spout that fits inside your water connection.
  • Pour water into the other end of the pipe using a funnel.
  • Remember that your source of water must be significantly greater than the inlet for this to work.
  • This technique is much more versatile instead of using pressure to fill your fresh water tank, but be conscious that it also allows for more debris to enter the system.

RV Water Filters

Any water used in your RV, whether city water or tank water, should always be processed. It’s a good idea to have a high-quality RV Water Filter connected to your hose so you can be sure that all of the water going to enter your system is hygienic.

The best water filters will eradicate any soil particles in the water as well as peculiar tastes and should be replaced every 6 months.

Some RVs also have completely separate filters in the kitchen sink and sometimes the bathroom, which should be changed every 6 months.

Sanitize Your RV’s Fresh Water System

 There are a few things you can do to keep your RV’s fresh water system in good working order and ensure it’s fully secure to use. Your RV’s water system offers all of the water you need for drinking, bathing, and dishwashing.

Unlike your home’s water pipes, it’s not reasonable to assume the system will always be clean and healthy, so it’s suggested that you sanitize your system to ensure your safety. If you never drink the water from your RV’s system, you may believe there is no need to sanitize it.

However, if you use it for anything, you should still renew it regularly.

The steps below will help you sanitize your RV’s fresh water system.

  • When you take your RV out of long-term storage, or if you observe an odd odor in the water system, you should sanitize it. It’s worth the time and effort because it can help you avoid some serious complications that can be caused by polluted water.
  • Every time you link your RV to a hookup or fill up the fresh water tank in another way, you’re introducing it to a different, unidentified source of drinking water. Although you should always use water that you know is secure for your RV, you can not be too cautious.
  • Always use a filtration system and, when necessary, sanitize your system. You should do it at least once every six months; it’s an essential facet of your RV’s care plan.
  • Begin by turning off the water heater. It is never a good idea to dry up a water heater while it is hot or under pressure.
  • Then, look for the low point water line drains; there should be one for hot water and one for cold water. Allow the water to drain by opening these.
  • You can now flip on your water pump to push the last of the water out of your system. Once the water has stopped draining, turn off the pump.

Tight all drains; there should be almost no water left in your RV’s system at this point.

  • For every 15 gallons of fresh water in your tank, use a quarter cup of household bleach. For example, if your tank holds 60 gallons, you will require one full cup of bleach.
  • In a one-gallon container, combine this with water and pour it into your fresh water tank.
  • After that, fill your tank with freshwater resources (using any of the techniques we’ve described).
  • Turn on your RV’s water pump and open all hot and cold water taps.
  • Run the water until you can smell bleach emerging from each water tap, then turn it off.

Then, set it aside for at least 12 hours.

  • Discharge the entire system once more, and then refill your tank with safe drinking water.
  • As a final step, re-open all of your water taps to wash out any residual bleach.
  • You should continue this procedure until there is no longer any bleach odor in the water system, as you do not want to digest and absorb any.
  • After you’ve completed all of these steps, you’ll have a healthy, hygienic, and safe-to-use RV water system.

Conclusion 

I hope this article has supplied you with all of the knowledge you require about the water system in your RV. Providing access to a true water system, complete with water taps, hand basins, and showers is a significant advantage of RV camping.

You’re now ready to experience your next camping trip, and your RV is completely prepared to transport you to your next camping location.

We wish you safe travels and a fun RVing experience!
