Suburban is one of the excellent manufacturers of these rods. As you know that these heating devices have short lifespans, and that’s why you require them after every 5-6 months.

The manufactures have increased the bulk production due to the immense use of RV and the internal device. Always check the quality and warranty of the device.

The manufacturing data plays a vital role in the precise use of the equipment. You can purchase a new heater water rod online as well.

There is a vast range of all types of heating rods with multiple sizes and cost ranges. The RV stores always supply these heating rods at excellent prices with maximum quality and efficiency. 

Maintain safety measures

The anode heating device also requires electric power for its normal functions. Always maintain the safety measure to protect yourself from any accident. Wear protective gloves so that you cannot touch the hot rods.

Use protective goggles to protect the eyes from hot water splashes. It is a harmful thing that causes patches and bruises on human skin.

Wear a standard protective uniform. And it should contain water resilient properties. All of these things offer maximum safety during the whole process. It keeps the installer fear-free, and he can perform the task with professional measures. 

Disconnect power supply

The heater anode rod of RVs gets its electrical power from the system. The batteries flow direct current that reaches such devices, and you cannot replace it in the presence of direct current. 

It leads to short circuits and accidents. Always disconnect the power supply.

Always make sure that the RV is not on the ignition because it is a source of current to the device. Disconnect all the plugs and sockets and observe the electric system.

If you doubt any small wire that can cause electric flow, and remove it from the panel. Make the vehicle electricity-free before even starting the process.

Locate the old heater

An anode of water heater in an RV is usually occurring in the water tanks. There is a panel of these heating devices.

All the installers and users of a recreational vehicle know about it. You should reach the electric source and remove it by using the screwdrivers. Remove all the nuts and screws and put the device aside. In this way, you approach the anode of the heating device. 

Allow water and heater to get less warm

When you turn off the electricity, then supply all the water and heating devices start cooling down. Leave the system for at least 1-2 hours.

The water in the tank is sometimes hot. Touching such devices leads to skin burns and irreversible damages, disconnect the power supplies of the RV.

If you do not unplug the water source, then it keeps mixing the hit water. In this way, the water will never cool down. Leave it for at least 30-40 minutes. It requires this time to cool down its anode rod. Some heaters need more time, do not touch the rod directly. 

Remove the valve 

There is a valve that helps it to be in its place. You require a socket, and they help in screwing off the valve.

These tiny devices are of a specific size, and you can use them anytime. Purchase them online or from any RV stores.

Drain water 

Draining water from the water tank of an RV is essential. You cannot replace a heating anode rod in the presence of already existing warm or cold water. Open the drain and valve area of the tank. 

Allow the free-flowing of water until it stops draining, and stay at a certain distance during the process. The splashing of hot water is harmful to the skin. Use a bucket in those cases when you think that the tank can splash a lot.

A bucket method is time-consuming, but it saves the user from deadly accidents. Drain the water in a dumping station or any other hose. Remove every droplet from the water tank. 

Leave this tank for at least 30-35 minutes, and it allows cooling of the tank’s walls. 

Check the electricity source

In this step, access the whole electricity panel. Learn all the instructions in the manual. You can also take expert help to carry out the installation process.

Choose the sockets and point where you are going to install the new device and its wires. Select the panel and clean it with a smooth cloth. It helps to provide a better view of the electricity sockets. 

Cover thread or tape the water heater anode rod

Few manufacturers of the heating anode rod provide them with coverings. There are few heating devices without any shield. Use protecting tape or threads to cover it.

You cannot insert an open electric heater in a control panel directly. You can apply the process to all types of anode rods. Cover the thread on the rod in a way that it completely hides it.

Wrap a layer of tape on all the thread areas. It helps in extreme protection conditions. Install the new device by following the manual’s process. Do not run it without removing the residual water. 

Run the water tank

Turn on the electric power of the water tank. You can use a pressure pump to remove the water. Rinse every wall of the tank with a cleaner.

It helps in the removal of any contaminants. The tank can get the toxic substances during the process and even after it. The pressure pumps help in deep cleaning. Further use becomes easy and comfortable for the users.

Remove air bubbles

The removal of air bubbles is also an essential thing. The air particles entrap in the valves, and they do not allow the heating.

The cold water flows after a stream of hot water, and it is not suitable for the proper functions of the heating anode rod.

Adjust the new device

Connect the wires of the heater rod with the panel of electricity. Tighten all the screws in a clockwise direction.

Turn on the system and check the leakage problems. In case of such issues, keep on tightening the screws. Secure the setup carefully, and replace the anode completely.

Never leave any old part of the previous heating device with the new one. It decreases the work efficiency of the heater and its anode rod.
