How Are Toilet Repair Kits Used?
Toilet repair kits are used to turn a malfunctioning toilet back into a functioning one. From time to time, toilets go wrong, and the culprit is often the internal workings. Flush mechanisms, flanges and valves all fail, but toilet repair kits are a cost-effective and simple way to sort the problem without calling in the professionals.
In general, toilet repair kits are easy to install and only take minutes before you have a functioning toilet again.
Are Toilet Repair Kits Universal?
Most are universal, like the Next By Danco or the Fluidmaster repair kits. However, specific toilet manufacturers make repair kits that fit their toilet brand. Kohler is one that springs to mind. When you are purchasing your replacement kit, if it says “Universal” on the box, there’s a strong chance that it will fit your toilet.
Types of Toilet Repair Kits
Some kits come with flappers, while others have replacement valves. Others specifically replace the flushing mechanism. There are different types of toilet repair kits to suit each specific problem.
Make sure the one you choose best covers the issues you have with your toilet. That’s why it’s worth doing your research first to discover what the actual problem is with your toilet before you splash out on a repair kit. If you are still unsure, get a complete toilet repair kit to cover all your bases.
How To Know What Toilet Kit You Need
So, you have an issue with your toilet, and now it’s time to determine where the problem lies. Determining where the fault lies is easier said than done. Invest in research to get to the root of the malfunction.
Check the Flapper
If the toilet continuously runs, this can be a significant issue, especially because it increases the quantity of water you use. Check the flapper to see if it is completely sealing the flush valve. If not, that could be the culprit and the reason why water runs constantly.
Replacing the flapper might solve the issue, but you may have to consider swapping the entire valve.
Check the Water Supply
Check that there are no water leaks. This is a costly problem both in the amount of water you use and the damage that water does to the toilet, the bathroom, and potentially the floor. Turn the nut about an eighth. Then check the supply line and make sure the connection is sound to the supply valve. You might want to consider replacing the valve if it’s over 5 years old.
Check the Fill Valve
If the toilet runs continuously, there might be problems with the fill valve. If you see debris on the valve or think it might be too old, replacing it would be a sensible move. Sometimes they can be cleaned, but in the main, if it looks like it needs a new one, it probably does.
Check the Bolts and Gasket
Sometimes bolts and gaskets fail as a result of age and wear and tear. If your gasket is the culprit, get a repair kit that includes replacements.
Pros and Cons of Toilet Repair Kits
As with everything, there is an upside and a downside. Here are the main pros and cons of toilet repair kits.
Pros
- Money-saving.
- Easier to install than a new toilet.
- No plumbing skills needed.
- Tailored kits for specific problems.
- Affordable.
Cons
- Requires basic knowledge of fault first.
- Detailed research to get the right kit.
- One size fits all.

Toilet Repair Kits FAQs
Flushed With Success
If you have an aging toilet, it might be an idea to upgrade the mechanisms rather than the toilet suite itself. It is cheaper and a better alternative if you want an instant result. Most toilet repair kits can be fitted in minutes, and many require no skills or tools.
So, if you have a continuously running toilet, or want to signal to the world your eco intentions, consider investing in a toilet repair kit. When the toilet breaks, you will be ready.
