Access to a reliable water supply is key to comfortable and enjoyable travels. Having a full water tank in your RV is important for more than just keeping you hydrated. It also plays an integral role in OTHER aspects of your travels.

A full water tank will PROVIDE you with ample hot water for showering, washing dishes, and doing laundry if you have that capability.

If not, having a full tank ensures enough water to properly rinse surfaces and items that need CLEANING while on the go.

Access to hot or cold running water can be a lifesaver when CAMPING in remote areas without hookups.

Additionally, having a full water tank means having extra weight in the rig, which helps keep it BALANCED during travel on rough terrain. This will help maintain a comfortable drive for you and your passengers.

Essential Supplies for Filling an RV Water Tank

Essential Supplies for Filling an RV Water Tank

Before you begin filling the tank, it’s essential to make sure that you have all of the necessary supplies. A fresh water hose, a pressure regulator and a filter are essential for ensuring clean and safe water.

Water Hose

The type of hose you get should be LONG enough to reach from your source of water (like a spigot or hydrant) to your RV. It should also be made from DURABLE and flexible materials such as rubber or PVC, as this will help reduce wear and tear over time.

Additionally, it’s best to choose one that is lead-free and NSF-certified for drinking water use to protect your HEALTH better and ensure cleanliness.

Pressure Regulator

If the area you’re filling the tank has a high-pressure water supply, it’s recommended to use a pressure regulator [1].

This will help keep the water flow at an ACCEPTABLE rate and protect your RV’s pipes from excessive pressure. It will also reduce the risk of bursting any hoses or fixtures due to high pressure.

Filter

Lastly, you’ll want to install a filter on your hose to remove sediment and other particles before they get into the tank. This will help keep the water CLEAN and reduce the risk of damage to the tank, hoses, and other components.

This filter should be changed regularly to ensure optimal FILTRATION and a safe drinking water supply for your RV [2].

Pro Tip: Use a filter with a replaceable cartridge to save you money in the long run.

Now that you have all your supplies ready, it’s time to start filling up the tank. Here are a few easy steps to follow:

Step 1: Attach Hose to Water Source

Once your supplies are ready, attach one end of the hose to a safe water source, like a spigot or hydrant. Ensure it is TIGHTLY secured, so there are no leaks in the line during filling.

Step 2: Connect the Pressure Regulator (If Applicable)

As mentioned, if the area you’re filling the tank has a high-pressure water supply, it’s recommended to use a pressure regulator. Connect it to the hose BETWEEN the water source and your RV.

Step 3: Attach Filter

Attach the filter to the end of the hose going into your RV. This will help keep sediment and other particles out of your tank to reduce DAMAGE to hoses and fixtures.

Step 4: Connect Hose to RV

Connect the opposite end of the hose securely to your RV’s intake valve. Make sure there are no LEAKS before proceeding with filling.

Step 5: Turn On Water Supply

Once all connections have been made, OPEN up the water supply at its source (like a spigot or hydrant).

Step 6: Monitor Flow and Fill Tank

Monitor the flow of water while filling your RV tank. When it has reached its desired level, turn off the water supply at its source and disconnect the hose from your RV. Make sure to close all valves TIGHTLY to prevent any leaks.

Step 7: Disconnect Hose and Clean Up

When you’re done filling the tank, disconnect the hose from both ends (the RV and the water source) before storing it away.

Do a FINAL check for leaks or damages on both hoses, filters and pressure regulators before putting them away for subsequent use. Finally, clean up any spilled water around where you filled your tank.

Pro Tip: Ensure to properly drain and store your hose when it’s not in use.

Clean Tank Regularly

It’s essential to clean your water tank REGULARLY. This can be done by draining out all the old water, opening the inspection ports and cleaning them with a mild soap solution.

Use Additives

If you’re storing your RV for an extended period, it’s recommended to use additives such as chlorine or hydrogen peroxide to help keep the water FRESH.

Check Water Source Quality

Before filling your tank, check the water source you’re using for any CONTAMINANTS or bacteria present in the water.

Monitor Pressure

Check and adjust pressure regulators while filling your tank to maintain a SAFE pressure level suitable for your RV.

If you suffer from low water pressure, check with your local city water supply for their recommended water pressure levels.

Store Hoses Properly

When you’re done filling, disconnect the hoses and store them PROPERLY in a dry place away from direct sunlight or extreme temperatures to prevent deterioration.

Add Sanitizer

To help keep your tank and plumbing system clean, add sanitizing PRODUCTS such as chlorine tablets or biodegradable camp soaps at least every two weeks when using your freshwater tank regularly.

Bleed Out Air

After filling the tank, it’s important to bleed out any trapped air in the lines, which can cause pressure changes and DECREASE the performance of pumps or fixtures while using them.

Pro Tip: Make sure to follow the manufacturer’s instructions when adding sanitizers and other additives, as they can affect pressure levels inside your tank.
