2. Aqua-Magic V RV Toilet Pedal Flush /High Profile / Parchment – Thetford – Best as the backup system.

1. 31705 Toilet Water Valve Kit – Best Overall

31705 Toilet Water Valve Kit, Compatible with Thetford Aqua-Magic V High and Low Models

This is the best overall RV toilet valve replacement kit because it is the universal system that you will find in most RVs. Most modern RVs already having this system in place and ready to be repaired usually do not require the seal. It should be noted that this system is easy to fit into older Thetford systems.

We recommend using this if you have a Thetford RV or even looking to upgrade the overall flow rate of your older RV toilet. Making the upgrade means keeping one or two of these in a storage compartment, with the repair only takes a few minutes to apply.

2. Aqua-Magic V RV Toilet Pedal Flush – Best Alternative Option

Aqua-Magic V RV Toilet Pedal Flush /High Profile / Parchment - Thetford 31672

While fixing a toilet valve should be the highest priority, there are times and situations where that is not possible when something goes wrong. This small toilet can fit in the storage compartment underneath the RV and be left there, ready to be used should a situation arise.

It is important to have alternatives because even if you have the right parts to fix the current toilet, you may not be able to use the toilet. It would be faster to remove the current toilet in many RVs and install a new one, requiring only a few screws to do correctly.

  • Easy to install
  • Requires no fiddling with valves
  • Easy to store once the main toilet is fixed.
  • Requires that you replace the entire toilet

Are All RV Toilet Flanges The Same?

Yes, all RV toilet flanges that have been made for standard RV toilets will be the same, with even regular toilets only having two distinct sizes. If you have a flange that looks oversized, it is meant to allow the pipes to properly rest on the rubber, with most smaller flanges only used in small RVs.

The standard sizes are 3-inches and 4-inches, allowing you to see which flanges will work with your toilet quickly. Many people mistakenly think that each toilet has its flange size and then try to use silicone to replace the flange.

However, the flange is meant to do more than stop water and assists in the total control that the pipes have over airflow. Permanent solutions usually cause the toilet to leak, as the vibrations from the moving RV break the seals that have been made.

How Do You Know What Model RV Toilet You Have?

We have also have and article called Best 7 Camper And RV Toilets that you can check out if your interested in a full toilet replacement!

Usually, the toilet’s model number and manufacturer name will be inside and under the toilet itself, with many brands proudly displaying their name somewhere as well. However, it should be noted that as the chemicals used to clean toilets are vital, the name may fade over time.

Many toilet manufacturers have found that engraving the model number works better, doing so in a spot close to the valve assembly. This allows you to look near the valve location and instantly see the toilet’s model, finding the right parts in a few clicks.

We recommend keeping some of the documentation for the toilet in a box with all the other documentation for the parts of your RV. When you buy a new RV with a toilet already installed, you can usually find the toilet brand and model number in the official documentation for the RV.

Do All RV Toilets Have The Same Fit?

Yes, all normal-sized RV toilets have the exact fit, working with the same types of pipes and other equipment. This allows RV manufacturers to quickly run through the same lines and equipment, preventing the RV build from getting so complicated.

No RV manufacturer wants to run five different types of pipes to the bathroom, which means that toilet manufacturers have made everything as uniform as possible. This has meant that the toilets all have similar sizes in each class while all use the same pipes for water and waste.

Further, if you have an RV with the space for a standard toilet, you won’t have to worry about the total fit. Your RV toilet is meant to make it easier to do some things, while the location you are camping in should have a toilet area where you can quickly and comfortably go about your regular ablutions.


The best RV toilet repair valve kit is the Thetford aqua-magic v high and low models compatible repair kit. It is affordable and allows you to quickly and comfortably repair most RV toilets without the stress that something might not fit entirely.

We have linked each kit and replacement kit to Amazon, making it as easy as possible to purchase enough extra for your RV trips around your state, country, or across into others!

Good luck, and happy camping!
