Diagnosing Your Toilet's Problem

Before you order a toilet repair kit, it’s a good idea to figure out what is going on with the toilet. Different problems require different components to fix them. When you have a good idea of what is going on with your toilet, you can find a kit that has the parts you need to make the repair. A little time spent before purchasing will save time, money, and aggravation later.

To diagnose the problem, start by turning off the water at the base of the toilet. There’s usually a valve on the wall. Turn it to the off position. Flush the toilet to empty the tank. Keep flushing until it’s as empty as possible.

Check the seals and valves for corrosion or mineral buildup. Both can cause problems. Look for corrosion on metal parts. Use steel wool to remove any mineral build-up. Verify the chain that opens the flap is hooked up and not snagged on something.

Let’s look at a few common toilet repair problems and what you will need to fix them.

Common Toilet Repair Issues and How to Fix Them

The Toilet Runs Intermittently or Flushes Randomly

The problem is likely the toilet’s floater ball or flapper mechanism. One or both are not reading the toilet’s water level properly. When that happens, the assembly keeps refilling the tank.

The fix for this is to refit the flapper valve. Replace the seals and gaskets. Find a toilet repair kit that includes a flapper valve. Most kits include seals and gaskets, though some don’t. The good news is that you can purchase the seals and gaskets for a low price. Make sure everything is tight before you refill the toilet and flush for the first time.

The Toilet Is Running Constantly

You constantly hear a trickle of water entering the toilet bowl. The problem is probably a leaky fill valve. In many cases, you will have a smaller float ball in the tank that’s attached to an arm. The mechanism isn’t reading the fact that there is enough water in the tank. It keeps drawing water to fill the tank, which causes the overflow to trickle into the bowl.

The first thing to do is examine the fill valve. If it’s mucked up or clogged, remove the valve and give it a good cleaning with vinegar and an old toothbrush. Many times that will fix the problem.

If the cleaning doesn’t fix the problem, you need to replace the fill valve. Buy a kit that includes the fill valve and the necessary fittings. While doing the work, you should replace all the components to make sure everything fits together. It will prevent other problems from developing due to old components.

The Toilet Isn't Flushing Completely or the Flush Is Weak

The problem could be with either the flush-valve cartridge or the air inducer on the fill valve. Remove the part and soak it in vinegar. Use a soft toothbrush to remove any mineral buildup or muck. If they are in good condition, put the originals back in place.

If you have hard water, however, you may need to replace the parts more often. Buy a toilet repair kit that includes the part you need to replace.

Another issue that can cause a weak flush is clogged water ports in the bowl. Use a mirror to check these ports. If you see them clogged with rust or mildew, use a wire hanger to clean the ports out. Then, flush and see if the strength improves.

Benefits of Toilet Repair Kits

You might wonder what are the benefits of buying a toilet repair kit over calling a plumber or buying a new toilet:

  • Buying repair parts and doing the work yourself is going to cost you less than hiring a plumber.
  • Getting repair parts will be cheaper than replacing the entire toilet. Plus, it’s usually a lot less work.
  • Most repair kits are made for the average homeowner. Many don’t require tools.
  • Newer repair kits can help you save on water because you can adjust the amount of water the toilet uses.
  • You can select a kit that includes the parts you need, so you don’t have to waste money on parts you don’t need.
  • Many kits will work across different toilet brands and styles.

Things to Keep In Mind When Buying Toilet Repair Kits

Even though buying toilet repair kits is often the best solution, there are a few things you should keep in mind when buying one:

  • Buy a kit with parts that fit your toilet. Universal kits are made to fit most toilet. However, always verify the flapper and fill valve will fit your particular toilet. Measure the drain at the bottom of the tank.
  • Verify what tools you will need to do the job. Many kits don’t require any tools. However, some do.
  • Always verify the kit includes the parts you need for your particular problem. Different kits include different components. 

Toilet repair kits can fix many common issues. However, they don’t fix them all. If your toilet is worn out or poorly designed, the repair kit won’t make it work like brand new. These kits work best for toilets that were working properly then developed a problem.

How to Select the Best Toilet Repair Kit

When selecting a toilet repair kit, there are a few things to keep in mind.

  • Ease of installation is critical, especially for those who are not experts at home improvement. The kit should include clear instructions with helpful illustrations.
  • High-quality components are essential. You don’t want to do all this work and have to replace the parts in six months.
  • Universal design kits make it easy to repair any toilet you might have. However, just because a kit is “universal”, that doesn’t mean it fits every toilet ever made. Always verify measurements before ordering.
  • Adjustability for water levels is a nice feature to have. It’s a great way to make an older toilet more water efficient.
  • Warranty is something to consider. Most kits come with a warranty, but some have better warranties than others.

And the Winner Is....

The Korky 4010PK Universal Complete Toilet Repair kit is the best toilet repair kit in our comparison. It includes all the parts needed to install the system. It offers modern technology to replace older, outdated systems, providing quieter operation. The manufacturer has taken steps to ensure the design is compatible with almost any brand of toilet.

Two notable design features are the fully adjustable flapper valve stem and flush valve stem. In other kits, such as the Plumbcraft 7029000 Toilet Repair Kit, the valve stems could only be adjusted by cutting off a portion of it. The fully adjustable stems in this kit make it much easier to install and adjust. Once the optimal level is found, the stem height locks into place.

The quality of the components is apparent. They are made to resist damage caused by chlorine, hard water, rust, well water, bacteria, and city water treatment. In comparison, the quality of the components included in the FlushSaver PUSH BUTTON EURO-STYLE Dual-Flush Deluxe DIY Conversion Kit is lower than in the Korky 4010pk kit.

The Korky kit can fix almost any problem your toilet’s internal systems were having. The kit includes all the pieces needed to do the conversion. It includes easy-to-follow instructions so that even a DIY newbie can install the components. The kit requires a minimum number of tools for installation, which is perfect for those with a limited tool set.

Another key feature of the Korky 4010PK Universal Complete Toilet Repair kit is the five-year warranty. While not as good as the seven-year warranty offered by FluidMaster, it is far better than the 90-day defective part warranty offered by FlushSaver. The quality of components include in the Korky kit makes the five-year warranty perfectly fine.

The main downside found with the Korky kit is that some older Gerber and Kohler toilets may not work with the included components. However, the kit works fine on toilets that are decades old as well as those manufactured in recent years.
