Rv Water Hookup: Using Regular Water Lines Safely

RVs, or recreational vehicles, are like portable homes. They need water, power, and sewer systems to function, and these are provided by RV hookups. RV hookups are places where you can connect your RV to a water and power source and drain wastewater. Campgrounds, RV parks, and even some national or state parks offer these hookups.

RV hookups are usually categorised into two types: full hookups and partial hookups. Full hookups provide water, electricity, and sewer connections, while partial hookups may only offer water and electricity. Campgrounds that don't offer any hookups are called dry camping sites, and campers have to supply their own power and water.

To hook up water to an RV, you'll need an RV drinking water hose and a water pressure regulator to ensure the water pressure from the campground doesn't damage your pipes. You can also use a water filtration system to improve water quality. Connect the hose to the water spigot and the city water connection on your RV, usually located on the driver's side exterior wall.

For electricity, RVs typically require either a 30-amp or 50-amp shore power connection. You'll need to use the appropriate power cord and adapter, if necessary, to connect to the campground's power source.

Using a water pressure regulator

A water pressure regulator is an essential accessory when connecting your camper to regular water lines. It ensures that your pipes don't burst if the water pressure coming from the campground is too strong.

Water pressure regulators are designed to reduce water pressure to a safe level for the plumbing systems in modern RVs. They also protect your RV's water hose and filtration systems.

The correct water pressure for an RV varies depending on the model and the condition of the plumbing system. Modern RVs can generally withstand water pressures of up to 100 psi, but most RV experts recommend never letting the water pressure exceed 60 psi. Somewhere around 40 to 55 psi is ideal for many RVs.

The best method is to screw the regulator directly onto the spigot for the city water supply. Then, attach a water filter to the regulator. Certain water pressure regulators have an integrated pressure gauge and filter. After the filter is in place, connect the city water hose to the filter. Finally, attach the other end of the hose to the RV's city water inlet.

There are a few different types of water pressure regulators:

• Single-stage: Single-stage adjustable regulators are the most common type. They have one pressure reduction stage, are typically adjustable, and are generally sufficient for most RVs.
• Preset: Preset regulators come pre-set to a specific output pressure, usually 40-45 psi, which is simple to use but offers less flexibility.
• Dual-stage: Dual-stage regulators have two stages of pressure reduction and offer finer control and greater stability, but are heavier, bulkier, and more expensive and are not typically used in most RVs due to their higher cost and complexity.

When choosing a water pressure regulator for your RV, consider the following:

• Pressure range: Ensure the regulator can handle the typical water pressure range of RV parks and campgrounds.
• Material: Regulators are generally made of brass or plastic. Brass is more durable and offers better longevity, but plastic regulators are cheaper.
• Connection type: The regulator should have standard hose fittings to connect to the RV and water source easily.
• Flow rate: The regulator should maintain an adequate flow rate to ensure you have enough water for daily tasks.
• Integrated gauge and filter: Some regulators have a built-in gauge that allows you to monitor the water pressure. A built-in filter can trap sediment and protect your RV's plumbing.

Connecting to city water

Once you've arrived at your campsite and parked your RV, you can begin the process of connecting to city water. Here are the steps to follow:

Step 1: Install a Pressure Regulator

Start by installing a water pressure regulator on the water spigot. This is an important safety measure, as it ensures that the water pressure from the campground doesn't exceed what your RV's pipes can handle, preventing them from bursting.

Step 2: Attach the Water Hose

Attach one end of your drinking water hose to the water pressure regulator. You may also choose to install an inline water filter at this stage to improve water quality.

Step 3: Connect to the RV

Now, take the other end of the hose and connect it to the city water connection on your RV. This is usually located on the driver's side exterior wall and will be a threaded connection.

Step 4: Turn on the Water

With everything connected, you can now turn on the water. Check that your RV's faucets have adequate water pressure and look for any signs of dripping or leaks at the connection points. If you notice any issues, shut off the water and check the O-rings on your hose and water pressure regulator.

By following these steps, you'll be able to safely and effectively connect your RV to city water, ensuring a steady supply of water for your trip.

Using a water filtration system

Choose a Water Filtration System

Select a water filtration system that suits your needs and the configuration of your camper. There are various options available, such as the Filtrete Maximum Under Sink Water Filtration System, which reduces lead, microbial cysts, chlorine taste and odour, and other contaminants. Alternatively, you can opt for the Nature Pure series by General Ecology, which offers enhanced performance and convenience features.

Plan the Layout

Before you begin installing the water filtration system, plan out where everything will go. Consider the space constraints and ensure that the water filtration system, water pump, and water tanks can fit comfortably. It's advisable to mount the pump and filter close to the faucet and water tanks to minimise tubing distances and increase flow pressure. Remember to leave enough room for maintenance and repairs.

Mount the Water Filtration System

Once you've decided on the location, mount the water filtration system securely to the cabinet or wall. Make sure to follow the manufacturer's instructions for proper installation. Some filters, like the Nature Pure series, need to be mounted vertically, and you must ensure sufficient clearance for changing the filter cartridge.

Connect the Water Filtration System to the Water Supply

Now, you'll connect the water filtration system to the water supply. The exact steps will depend on your specific setup, but here are some general guidelines:

• Use the appropriate tubing to connect the water filtration system to the water pump or directly to the water source if you don't have a pump.
• Ensure all connections are secure and use hose clamps where necessary.
• Follow the instructions provided with your water filtration system for any specific connection requirements.

Connect the Water Filtration System to the Faucet

After connecting the water supply, you'll need to run tubing from the output of the water filtration system to the dedicated faucet. Again, use the appropriate tubing and secure all connections. If your system uses quick-connect fittings, push the tubing into the fitting until it stops, then gently tug on it to set the connection.

Test the System

Once everything is connected, it's time to test your new water filtration system. Turn on the water supply and slowly open the faucet. Check for any leaks along the tubing and connections. If everything seems watertight, let the water run for a few minutes to ensure the filtration system is functioning properly.

By following these steps, you'll have a working water filtration system in your camper, providing you with clean and safe drinking water no matter where your adventures take you. Remember to regularly maintain and replace filter cartridges as recommended by the manufacturer.

The importance of water hose length

The water hose length is an important consideration when connecting a camper to regular water lines. Here are some reasons why:

• Water Source Accessibility: The distance between the RV and the water source at the campsite can vary significantly. A longer hose may be required to reach the water source in some campgrounds, while others may have water hookups closer to the RV parking area. A hose that is too short can cause inconvenience and limit your camping options.
• RV Size: The length of the hose needed is directly related to the size of your RV. A larger RV will likely require a longer hose to reach the water hookup point. Measuring the distance between the RV tanks and the water hookup point can help determine the minimum hose length required.
• Storage Space: Longer hoses may require more storage space when not in use due to their weight and bulkiness. Shorter hoses are more compact and easier to store, especially if you have limited space in your RV.
• Flexibility: Flexibility is crucial when it comes to water hoses. A hose that is too rigid can be difficult to work with and prone to kinking. A flexible hose that can bend and fit into tight spaces is generally easier to use.
• Leak Prevention: Having a single long hose instead of multiple shorter ones connected together reduces the number of connections, lowering the risk of leaks. The fewer connections you have to make, the less likely you are to experience leaks.
• Sanitation: Using a single long hose also reduces the number of exposed ends, lowering the risk of contaminating your drinking water. However, longer hoses can be more challenging to clean and dry, providing a favourable environment for mould and mildew growth.
• Water Flow: Water flow can be affected by the length of the hose. A shorter hose, such as a 25-foot hose, can provide better water flow compared to a longer 50-foot hose.
• Personal Preference: Ultimately, the choice of hose length depends on personal preference and what works best for your RV setup. Some RVers prefer the convenience of a longer hose, while others opt for a shorter hose for ease of use and storage.

When selecting a water hose length for your camper, it is important to consider factors such as the distance to the water source, the size of your RV, storage space constraints, and the flexibility and functionality of the hose. A hose that is too short can limit your camping options, while a hose that is too long can be cumbersome and difficult to manage. Finding the right balance between length and ease of use is essential for a comfortable and enjoyable camping experience.

How to fill the fresh water tank

Filling your RV's fresh water tank is essential to ensure you have access to clean and reliable water during your road trips and camping adventures. Here is a step-by-step guide on how to fill your RV's fresh water tank:

Step 1: Prepare the necessary equipment

• Potable water hose: Use a dedicated potable water hose that is specifically designed for RV use. These hoses are typically white or blue and are labelled as safe for drinking water. Do not use a regular garden hose as it may contain chemicals or contaminants.
• Water filter: If your RV lacks an onboard filtration system, you will need a water filter to ensure the water entering your tank is clean and safe.
• Water pressure regulator: This device ensures that the water entering your RV is at a safe pressure and prevents damage to your RV's plumbing.

Step 2: Locate the fresh water tank fill

The fresh water tank fill is usually found on the off-camp side of your RV, opposite the main entry door. However, some RVs may have the fill location on the camp side or at the back. If you're having trouble locating it, consult your owner's manual.

Step 3: Position your RV near a potable water source

Park your RV close enough to the potable water source so that your potable water hose can reach between the spigot and your fresh tank fill. The distance will depend on the length of your hose.

Step 4: Connect the water filter and hose

• Connect your RV water filter to the spigot.
• Connect your fresh water hose to the water filter.

Step 5: Fill the fresh water tank

• Insert the open end of your water hose into the fresh tank fill.
• Turn on the water spigot and let it run until you see water spurting out of the tank vent.
• Turn off the spigot, remove the hose from the tank fill, and replace the fill cap.
• Disconnect the hose and filter, then clear the water from the hose before storing it.

Step 6: Turn on the RV's water pump

After filling your fresh water tank, remember to turn on your RV's water pump to pressurize the lines. This will ensure water flows from your faucets and shower when you need it.

Best Practices and Tips

• Sanitize your water system: Before long trips or after extended storage, use a sanitizing solution to clean the tank and water lines.
• Monitor water levels: Keep an eye on your fresh water levels, especially when boondocking or camping without hookups. Refill when the tank drops below 50% to ensure you don't run out.
• Use a water pressure regulator: Always use a water pressure regulator when connecting to an external water source to prevent damage to your RV's plumbing.
• Keep RV hoses separate: Dedicate a separate hose for your freshwater system and do not use it for any other purpose to avoid contamination.
• Clean your fresh water tank: If your water develops an odour, drain and sanitize the fresh water tank using a freshwater tank sanitizer.
