If you own an RV, you may be wondering when to open or close your faucets. To prevent damage and save on water bills, it is important to know how to handle the faucets in your RV properly.
RV Faucets – do you leave open or closed?

Open RV faucets are most commonly used when the RV is stationary. They feature an open spout that allows water to flow freely, even when not in use. Open spouts are also typically easier to regulate than closed spouts, making them ideal for those who need precise control over the water flow.
Closed RV faucets, on the other hand, are often used while traveling or parked in colder climates. These faucets have a valve at the base of the spout which completely stops water from flowing when it’s closed. This helps to prevent backflow and minimize water waste by ensuring that no water is accidentally left running.
When deciding whether to leave your RV faucet open or closed, it really depends on your individual situation. If you’re parked in a warm climate and won’t be travelling for a while, you can leave the faucet open to allow for easier water regulation. However, if you’re travelling or parking in colder climates, it’s best to keep the faucet closed to avoid any potential backflow.
Things you do not want to forget when winterizing

- Before pumping the pink stuff through the system, be sure to bypass the water heater. Additionally, leave the water heater drain valve out for the winter, as nothing is going to crawl up in there.
- After winterizing, push in the little check valve stem on the city water inlet before turning off the pump; there is water trapped between the pump and the check valve that needs to be purged, so stand aside if you don’t want a pink shower.
- Additionally, open the outside shower faucets until the pink stuff flows out and pour some anti-freeze down every drain to fill the traps, including the bathroom and kitchen sink and shower drain, as well as in the toilet to keep the ball seal moist throughout the winter.
- Open the black tank and grey tank valves, but make sure the exhaust tube has the cover in place after all liquid has drained, so as to not give mice any opportunity to crawl up there and build a nest.
- Lastly, remove all cans, bottles, paper products, linens, dry foods and other materials to prevent freezing and breakage and to not provide mice with food or nesting material.
How to close an RV faucet properly
If you need to close an RV faucet, make sure to do it correctly. First, locate the valve at the base of the spout and turn it in a clockwise direction until it is completely closed. This will help ensure that no water escapes while your RV is parked or travelling.
Once you have successfully closed your RV faucet, make sure to keep an eye on it regularly. Check for any signs of leakage or backflow as this can cause damage to your RV’s plumbing system. It’s also important to remember that closed faucets don’t provide any protection against freezing temperatures – so if you plan to park in colder climates, you may want to consider investing in a faucet cover.
When to leave your RV faucet open?
If you’re planning on staying in one place for a while, leaving your RV faucet open can be beneficial. Open spouts are usually easier to regulate than closed ones, so it’s ideal for those who need precise control over the water flow. Additionally, an open faucet helps to prevent backflow by providing a steady flow of water through the system, thus reducing the risk of damage caused by leaking or freezing pipes.
However, if you plan on travelling or parking in colder climates, it’s best to keep your RV faucet closed. This will help ensure that no water escapes and minimize the risk of backflow and leakage. Remember to close the valve completely before setting off on your journey!
How to tell if your RV faucet is leaking
If you think your RV faucet may be leaking, there are a few things to look for. Check for any signs of water on the floor or around the spout, as this is an indication that something is wrong. Also, listen closely for any dripping sounds coming from the valve or spout – if you can hear what sounds like a leak, it’s best to get it checked out right away.
Finally, take note of how much water pressure is coming out of your faucet. If there’s no pressure at all, it could mean that the valve is not completely shut or that there’s a blockage in the pipes. In either case, it’s important to get your RV faucet repaired immediately.
Whether you’re leaving your RV faucet open or closed, it’s important to make sure it’s handled properly. Following the steps above can help ensure that your RV plumbing system is functioning correctly and safely. With a little bit of know-how, you’ll be able to keep your RV faucets running smoothly for years to come!
The Verdict
Whether you should leave open or close your RV faucet depends on the situation. If you plan to stay in one place for a while, keeping it open is ideal as it helps regulate water flow and prevents backflow. However, if you plan on travelling or parking in colder climates, it’s best to keep your RV faucet closed to ensure no water escapes. Whatever you decide, be sure to check for any signs of leaking or backflow, as this can cause damage to your plumbing system. Additionally, remember not to forget winterizing correctly before storing your RV! With these tips in mind, you’ll have a safe and successful camping season!
