How to Unclog RV Shower Drain

From using simple household items to employing specialized tools, we will explore various techniques that can remove the blockage and restore proper water flow. Don’t let a clogged shower drain dampen your RV adventures—read on to learn how to unclog your RV shower drain and get back to enjoying a refreshing shower on the road.

Importance of a Clear and Functional RV Shower Drain

It is important to be able to keep your RV shower drain clear and functional for a variety of reasons. Firstly, it is essential to ensure that the water from the shower drains properly – otherwise you may end up with water pooling in the bottom of the shower or leaking onto the floor outside of it. This can lead to damage and potential health hazards such as mold growth.

Secondly, an unclogged drain will reduce blockages which could cause bad odors. 

Finally, clogged drains can slow down drainage significantly, meaning that showers take longer and use more water than necessary. Therefore, undertaking regular maintenance on your RV’s shower drain will help keep it in good condition and functioning optimally.

In order to keep your RV shower drain unclogged, it is important to regularly clear away any debris or buildup of hair. This can be done using a plunger or snake tool, which will help push out any blockages and allow the water to flow freely again.

Additionally, it is helpful to use an enzyme-based cleaner as this can break down organic material such as soap scum and body oils which may otherwise build up in the pipes over time. Following these steps regularly can help ensure that your RV shower drain remains unclogged and functional for many years to come.

Common Causes of RV Shower Drain Clogs

Clogs in RV shower drains are usually caused by a buildup of hair, soap scum, and other debris. Hair can get trapped in the drain screen or pipes and eventually form a clog. Soap scum can accumulate on the sides of the pipes, reducing the flow of water through them. Other objects such as toys, trash, and dental floss may also get stuck in the pipes causing further blockage.

Hair Can Get Trapped in the Drain Screen

The most common cause of an RV shower drain clog is inadequate cleaning. Routine maintenance should be done to ensure debris is not building up inside your pipes. Additionally, using chemical cleaners designed for RV showers can help keep your pipes clear and reduce the likelihood of a clog occurring.

If you have an old RV, its plumbing system may be outdated and prone to clogging more easily than newer models. This is because older pipes are often narrower than modern plumbing systems and can become blocked quickly by debris. It is important to check your drain screens regularly and replace them when necessary.

Finally, it’s possible that the source of the shower clog could be further down the line in your home’s main sewer line. If this is the case, professional services will likely need to be called in for assistance.

Understanding RV Shower Drain Clogs

Before attempting to unclog your RV shower drain, it is important to understand what kind of clog you are dealing with and why it happened in the first place. In most cases, a simple clog can be caused by hair or built-up soap scum and debris that has accumulated over time.

If this is the case, then an easy solution like using a plunger or drain snake should do the trick. However, if the clog is more severe, then it may have been caused by something like debris from food particles that have gummed up the works.

Once you know what kind of clog you’re dealing with, you can start taking steps to unclog your RV shower drain. Depending on the type of clog, you may need to use a combination of tools and techniques. Read on for some helpful tips that can help you unclog your RV shower drain quickly and easily.

Signs of a Clogged Rv Shower Drain

The most obvious sign of a clogged RV shower drain is water backing up in the shower or tub. You may also notice gurgling sounds coming from the drain when you turn on the faucet, as well as foul odors emanating from the drain. A slow draining tub is another telltale sign that your RV shower drain might be blocked. If you are dealing with any of these issues, it’s time to unclog your RV shower drain.

Fortunately, unclogging an RV shower drain isn’t complicated and can usually be done with just a few simple tools. Before starting, make sure to shut off all water valves connected to the RV so no backflow occurs while you work on the drain. Then, use a plunger to try and loosen any blockages in the pipe.

If that doesn’t work, you may need to disassemble the drain assembly using an adjustable wrench and remove any clogs with needle nose pliers or a wire brush.

Finally, rinse out the entire area with hot water and reassemble the drain assembly. This should restore your RV shower drain back to normal and prevent any further clogging. If these steps do not work, you may have a more serious clog that requires professional help.

10 Ways How to Unclog Rv Shower Drain

Method 1: Boiling Water

Begin with the simplest method—boiling water. Boil a pot or kettle of water and carefully pour it down the drain. The hot water can help break up and flush away any debris or clogs.

Method 2: Plunger

Using a plunger specifically designed for RV drains, create a seal over the drain and plunge vigorously. The suction and pressure created by plunging can dislodge the clog and restore proper water flow.

Create a Seal Over the Drain and Plunge

Method 3: Vinegar and Baking Soda

Combine equal parts vinegar and baking soda to create a natural and foaming drain cleaner. Pour this mixture down the drain and let it sit for about 30 minutes. Then, flush the drain with hot water to clear away the clog.

Method 4: Hot Water and Dish Soap

Squirt a generous amount of dish soap into the drain and pour hot water over it. Allow it to sit for a few minutes to penetrate the clog. Then, flush the drain with more hot water to remove the loosened debris.

Method 5: Plumbing Snake or Drain Auger

If the clog persists, a plumbing snake or drain auger can be effective. Insert the snake into the drain and rotate it while pushing it forward. This action helps break up the clog and allows you to remove it or push it further down the drain.

Method 6: Enzyme Cleaners

Enzyme-based drain cleaners specifically designed for RVs can effectively dissolve organic matter and clogs. Follow the instructions on the cleaner’s packaging, allowing it enough time to work before flushing the drain with water.

Method 7: Wet/Dry Vacuum

If you have a wet dry vacuum, you can use it to suction out the clog. Set the vacuum to the wet mode, cover the vent to create a seal, and place the hose directly over the drain. The vacuum’s suction can pull out the clog.

Method 8: Wire Hanger

Straighten a wire hanger and create a small hook at one end. Insert the hooked end into the drain and fish out any debris or hair causing the clog. Repeat the process several times until the drain is clear.

Method 9: Dissolving Tablets or Powder

Some RV stores sell dissolving tablets or powder specifically formulated to remove clogs in RV drains. Follow the instructions provided with the product, typically requiring you to dissolve the tablet or powder in water and pour it down the drain.

Method 10: Seek Professional Help

If the clog remains stubborn or if you’re uncomfortable performing DIY methods, it may be best to seek professional help. Contact an RV repair specialist or a plumber with experience in RV systems to diagnose and resolve the clog professionally.

Things to Consider When Unclogging RV Shower Drain

When trying to unclog an RV shower drain, there are some important things to consider. First and foremost is safety. Make sure that the area around the drain is free of standing water or any other hazards prior to beginning work. It’s also a good idea to wear protective clothing, such as gloves and safety glasses, when attempting to unclog a drain.

Next, evaluate the type of clog that is present. If there appears to be an accumulation of soap scum or other debris, then it’s likely that the drain can be unclogged using a plunger. For more stubborn clogs, such as grease or oil buildup, it may be necessary to use specialized tools or chemicals.

In addition to the above considerations, it’s also important to check for any damage that may have been caused by the clog itself. For example, if there are cracks in the piping or other signs of wear and tear, these should be addressed prior to attempting to clear away the blockage.

Check for Any Damage

Finally, if all else fails and you find yourself unable to unclog the RV shower drain, it may be best to contact a professional plumber for assistance.


Though unclogging an RV shower drain can be intimidating, it does not have to be a difficult process. In most cases, a clogged pipe can be cleared with some patience and the correct tools.

Though plungers may be seen as the go-to tool for clearing clogged drains, they are not the only tool available. Chemicals like baking soda and vinegar could help clear a blockage in less time than what a plunger might take.

However, if all else fails, it might be wise to seek professional guidance. Unclogging RV showers need not bring about a downfall when you are aware of the different methods available. Follow these simple instructions outlined in this blog post about how to unclog rv shower drain, and you’ll be able to get the job done with ease.
