Replacing an RV toilet is not the easiest thing to do. However, with the proper guidance you will feel confident to do so. This article will detail everything you need to know about RV toilet replacement.
Before you try to replace your RV toilet, make sure that it actually needs replacing. Sometimes a leaky toilet only needs a water valve replacement. Therefore, check the components of the toilet to find the broken culprit. You may only need to replace only one part instead of the whole toilet. Thus, finding the issue could save you time and money.
How to Replace RV Water Valve
A broken water valve is one of the most common RV toilet malfunctions. Look for leaks to determine whether it needs replacing. If yours breaks, follow these steps to replace it.
- Park RV on a level surface, and fully dump out the black tank. Then turn off the water pump to your toilet.
- Remove toilet base cover and toilet handle. Set aside all screws for future use.
- Remove the water valve at the back of the toilet.
- Clean out the small mesh net at the back. It sometimes collects minerals and other debris.
- Attach the new water valve, using the new screws included with the new kit.
- Turn the water and water pump back on and check for leaks. If it looks good, replace the toilet base cover and toilet handle.
How to Select a Replacement RV Toilet
- Look at the features and benefits of the replacement toilet. First and foremost you need to select one that matches with your previous toilet’s mount. Check the mount measurements and type so that you can match them with the replacement. Also check your waste hole first to see which toilets will fit. After that you can focus on other details such as flush power system, bidet attachments and water levels.
- Pick a bowl seat and toilet height. This factor depends on your personal preferences for maximum comfort.
- Choose a color and shape. Most toilets come in either white or bone color, while some brands offer additional colors. When deciding on a shape, make sure that the measurements work with your RV restroom space and previous mount style. Working within the parameters of your previous mount will save you a lot of trouble.
- Next you will need to pick a flush. From foot pedals, slide handles and electric push buttons, RV toilets offer several options. Choose the one to your preference that works with your selected toilet model.
- Choose your materials. RV toilets are made from plastic, china and a mix of the two. Plastic toilets generally cost less than china ones, while china tends to provide a more homey feel.
- Pick your brand. Dometic and Thetford are the most popular brands for RV toilets. When it comes to composting toilets, Nature’s Head is the most popular choice. Order your toilet in advance, as you may have to wait.
How to Replace your RV Toilet
Once you determined that the whole toilet needs replacing and ordered your replacement, you are ready to begin,
- Turn off the water pump and flush the toilet. You want to clear all the lines and relieve pressure. Next, remove the old toilet. Unscrew all connections between the toilet and water pipes.
- Clean around the base. Sometimes floor wax or silicone have secured it to the floor, so remove these if necessary. Mind the tank hole and secure anything that might fall down it.
- Dump out the RV waste tank completely before removing the old plumbing connections. Once complete, you can unscrew the hoses and connection from the old toilet which lead to the black water tank.
- Replace the gasket between the toilet and the floor. Place the new RV toilet on the new gasket, lining up all mounting holes.
- Screw in the new toilet to the mounting holes with the new parts. Make a snug fit but do not over tighten. Sit on the toilet and check for movement and level.
- Reconnect the water house to the toilet. Do not over tighten.
- Finally, you can turn the water back on. Flush the toilet and check it for any leaks. Check around the fittings and below the toilet. And that’s it.
Replacing an RV toilet takes patience. Take your time and make sure you read all manufacturer information on your new toilet. Each toilet might be a little different, so make sure you take the appropriate steps according to the manufacturer.
When you want a specific kind of toilet, place your order a few weeks out. It can take some time to actually receive it. Whenever you feel uncomfortable or overwhelmed with your RV toilet replacement, contact a professional RV technician for support.
