Taking the time to drain your RV water heater is crucial for the long-term health of your RV. Not only will it help extend the life of your water heater, but it can also save you money on costly repairs down the line. This guide will walk you through how to drain a RV water heater.
To drain an RV water heater, turn off the heater, let it cool, and find the drain valve. Connect a hose, open the valve, and let the water flow out.
Where Is the RV Water Heater Drain?
The water heater drain on a Recreational Vehicle (RV) can usually be found near the vehicle’s rear, under, or close to the water heater. In most cases, it is accessible from outside the RV, although some models require access from within.
Once you locate your water heater, look for a small funnel-like outlet connected to piping leading from the hot-water storage tank and dispersing onto the ground. This outlet is typically made of steel and may have a flange around it for additional security or an attached shutoff valve.
Not all RVs come with an external drain; some depend on gravity flow down through an interior pipe system to reach its intended location away from the vehicle.
Additionally, certain RV water heaters require zero drainage—meaning they use other means to dispose of heated wastewater, such as evaporation or discharge directly into fresh holding tanks on board your camper or motorhome.
The best way to determine where your specific model’s RV water heater drain is located is by referring to your owner’s manual and consulting with a qualified service technician if unsure.

How To Drain A RV Water Heater | Step By Step Procedure
Draining Your RV Water Heater – Step One
The first thing you need to do before draining your RV water heater is to turn off all electricity and gas sources connected to it. This includes turning off any circuit breakers, shutting off the propane tank, and disconnecting any attached wires. Make sure you’ve done this properly before continuing.
Draining Your RV Water Heater – Step Two
Once all power sources have been turned off, you can begin draining your water heater by removing its cover panel. This will give you access to the pressure relief valve near the top of the tank. You can identify this valve by its hexagonal shape and red or yellow handle.
Draining Your RV Water Heater – Step Three
Once you’ve identified the pressure relief valve, open it slowly until a steady stream of hot water begins flowing into a bucket or other container placed beneath it.
Allow the hot water to continue running until drained from the tank, and then close the valve securely again. Once complete, replace the cover panel on your water heater so that everything is safely in place again.

How Often Should You Drain Your Rv Water Heater?
Draining your RV water heater is important to maintaining your recreational vehicle. Depending on the type of water heater you have, the frequency at which it needs to be drained can vary significantly.
If you have a conventional electric or gas-powered water heater, it’s typically recommended to drain it once every 3 months. This helps ensure that any debris and solids will not build up in the tank over time, resulting in poor performance or damage down the road.
Additionally, draining your RV’s hot water tank at least once every three months will help keep sediment from building up inside and potentially damaging interior components.
On the other hand, draining may be unnecessary if you own a more modern instant hot-water system (also known as an “on-demand” setup) because these models don’t hold standing water within their tanks as traditional systems do. Instead, it produces hot water as needed on demand without storing anything internally, so there’s no need to worry about drainage/cleaning requirements here!
Regardless of which type of RV hot-water setup you have, make sure to check with manufacturer instructions for specifics related to maintenance schedules & servicing requirements – this way; repairs won’t come as a surprise later on down the road!

What Happens If You Don’t Drain Your Water Heater?
Not draining your water heater can lead to some disastrous results. Not only does it reduce the life of your appliance, but neglecting to drain a water heater can also cause serious issues like mineral buildup and corrosion.
This buildup can prevent heaters from operating properly and create an environment where harmful bacteria may grow, putting you and your family at risk of illness. Also, if sediment is allowed to remain, it will raise pressure levels, heightening the risk of dangerous leaks or bursts that can cause property damage and costly repairs.
In short, routine maintenance is key to ensure that your water heater stays in top condition and continues to provide clean hot water for you and your home.
