How to Drain Water Lines in Camper

If you live in an area where the temperatures drop below freezing, then you know it’s important to drain your water lines in your camper. Here are some simple instructions on how to do this: 1. Start by turning off the water at the main supply.

This will prevent any water from entering the lines while you’re working. 2. Next, open all of the faucets in your camper and let them run until the water stops flowing. This will help to empty out as much water from the lines as possible.

3. Once the water has stopped running from the faucets, close them and move on to flushing the toilet(s). Again, let the water run until it stops before moving on. 4. The last step is to add RV antifreeze to all of your drains (sinks, showers, etc.).

This will help to protect your pipes from freezing and bursting during extreme cold weather conditions.

Does Low Point Drain Empty Water Heater

If your water heater is drained for any reason, it’s important to know that the low point drain may not be completely empty. There could still be some water left in the tank, which means you’ll need to take extra care when relighting the pilot light or igniting the burner. If you don’t, you could end up with a big mess on your hands.

How to Fill Water Heater in Rv

Assuming you have a typical RV water heater, there should be a city water connection inlet on the outside of your rig. If not, you will need to fill the tank manually using a hose. Before you begin, make sure that the fresh water valve is turned off.

Then, open the low point drains to release any built up pressure and remove any residual water from the lines. Next, attach your hose to the city water connection inlet and turn on the water. The final step is to open all of your faucets inside the RV one at a time until water starts flowing from them.

This will help bleed any air out of the lines.

The best way to locate it is to get under your RV with a flashlight and look for a small handle that says “fresh water drain” or something similar. Once you find it, trace the hose back to see where it goes into your RV (this is how you’ll know which side of your rig the valve is on).

How Do I Drain the Hot Water Heater on My Rv?

If your RV has a hot water heater, chances are it’s the type that uses propane gas to heat up the water. These types of heaters have a tank that needs to be drained periodically in order to prevent rust and corrosion. Draining the tank is a pretty simple process, but there are a few things you need to know before you get started.

First, make sure that you shut off the gas supply to the heater. There should be a knob or lever on the side of the unit that controls the gas flow. Once the gas is shut off, open all of the faucets in your RV so that any remaining water can drain out of the system.

Next, locate the drain valve on your hot water heater. This is usually located near the bottom of the unit, and will have a handle that you can turn to open it up. Place a bucket underneath the valve so that you can catch any water that comes out when you open it up.

Now it’s time to actually open up the drain valve and let all of the water out of the tank. You may want to do this slowly at first so that you don’t make too much of a mess.

Do I Need to Drain My Rv Hot Water Heater?

Yes, you should drain your RV hot water heater on a regular basis—at least once per season, and more often if you use it frequently. Draining the tank helps to remove sediments that can build up over time and cause problems with the heater’s performance. It’s a simple process that only takes a few minutes, so there’s no excuse not to do it!

Where is Rv Water Heater Drain?

If you’re looking for the RV water heater drain, it’s likely that you’re trying to do some maintenance on your rig. Draining the water heater is an important part of regular maintenance, and it’s not difficult to do. Here’s a quick guide to help you find the RV water heater drain and get the job done.

The first step is to locate the fresh water tank. This is usually located towards the front of the RV, under one of the benches or in a cabinet. Once you’ve found the tank, look for a small valve near the bottom.

This is the RV water heater drain valve. To begin draining your water heater, start by opening this valve and placing a bowl or bucket underneath to catch any dripping water. Next, turn off your water heater’s power switch (usually located inside) and open up the pressure relief valve (this may be located on top of your unit).

Now simply let all of the water run out until it stops dripping completely – this can take a few minutes. Once all of the water has been drained, close both valves and turn your power switch back on. You’ve now successfully completed draining your RV’s water heater!

How Do You Drain All the Water Out of a Hot Water Heater?

If your water heater is electric, you’ll need to shut off power to the unit before draining it. For a gas water heater, simply turn the knob on the control valve to the “off” position. Next, open the pressure relief valve and any cold water inlet valves that are located on your water heater.

Doing so will release any pressure that’s built up inside the tank. Now attach a garden hose to the drain valve at the bottom of your water heater and route it to an area where the drainage won’t be an issue. Finally, open up the drain valve and allow all of the water to exit from the tank.

Once all of the water has been drained, close both valves and restore power (if applicable).


If you need to drain your RV hot water heater, there are a few simple steps you can follow. First, turn off the power to the heater and make sure that the valves are in the correct position. Next, open the drain valve and let all of the water out.

Once the water is gone, close the valve and turn on the power to the heater. You should now be able to use your RV hot water heater without any problems.
