If you are into hiking or camping, buying an RV toilet is an excellent investment. They are lightweight, convenient, and easy to use. However, even top-quality units can have problems over time, such as not being able to hold water. In this article, we will check the most common causes of that problem and explain how to fix it.
Some Basics About RV Toilets
Not being able to hold water is a common problem among RV toilets. The good thing is that RV toilets are simple devices, and most of them operate in a similar way. In most cases, if the toilet won’t hold water, it’s because the blade seal is damaged. It might even harden over time and the mechanism will stop working, requiring a replacement blade seal.
How to Fix an RV Toilet That Won’t Hold Water?
Of course, you can always call a plumber to fix the problem for you. However, fixing this problem requires only some basic DIY skills, so if you are handy, it won’t be a problem.
Choose the Right Repair Kit
The first thing that you need to clarify is what type of RV toilet you have. It’s even better if you still have an instruction manual at hand. If you don’t, you can check the unit serial number on the base of the unit. However, no matter the model, you will be able to find a blade seal in most hardware stores for around $20.
How to Replace the Seal?
First, turn off the water supply and empty the toilet from water and pressure. Then, remove the bolts that hold the unit to the floor, and detach the water pipe behind the unit. Remove the toilet carefully and place it in a safe place. Then, put a towel on the exposed waste hole and locate the seal. There is a ring that you need to remove and put a new one in the same location. Before you start with replacing, add a bit of water to ensure that the seal is holding water properly. After you replace the seal, install the toilet back and make sure to properly tighten the bolts. Finally, let the water run and test to see if it’s working.
Other Causes of the Problem
Broken Water Valve
Over time, the water valve will wear off and you will need to replace it. It’s replacement time if you notice that the water continues to run after you flush. Note that the problem usually happens when the water valve gets frozen and then heated at a normal temperature multiple times. However, it’s a simple fix, and water valves are usually very affordable.
Broken or Worn Flange
Damaged toilet flange is another common problem among RV toilets. If you notice leakage around the base of the unit, it’s probably because the flange has worn off.
Since most parts are rubber or plastic, they will eventually wear down sooner or later. However, no matter which part you need to replace, you should be able to find it online without issue.
As you can see, being unable to hold water is a common problem among RV toilets. However, it’s simple to fix and costs almost nothing. If you worry about shipping costs or extra fees, be sure to check a nearby hardware store for replacement parts.
