A running toilet is an integral part of any busy household, but what happens when this important utility breaks?
Hiring a plumber to fix your leaking pipes or replacing the toilet altogether can be costly, so being able to fix it yourself can save you a lot of money.
However, knowing how to go about this can be a challenge when you’re inexperienced with home maintenance.
There are many parts of a toilet that can fail, and finding a repair kit that can offer you a complete solution is a key to performing a professional and efficient job.
These kits are an inexpensive way to take care of the occasional leak, or even upgrade your entire system.
What Is A Toilet Repair Kit
When your toilet is leaking, or you experience phantom flushes, where the toilet seems to flush without anyone triggering it, then you have a broken flush.
Other symptoms of these problems are the fact that your toilet has begun to lack the power to flush properly, and the capacity for waste removal has been reduced.
These times can be stressful, as your first thought may be to call a plumber, but there’s a way to avoid this expensive route.
A toilet repair kit is an inexpensive alternative to calling a plumber. Featuring replacement parts for your entire flushing mechanism, from the fill valve to flapper, this kit allows you to quickly and efficiently repair your toilet so that it is flushing as good as new.
They are very easy to install, so you can often perform the entire fix yourself, no matter who you are. Fixing your toilet in this way can help you to gain the confidence to tackle any DIY challenge around your home.

How To Identify The Source Of Your Leak
Your toilet flush system is a mechanism that involves many parts. Being able to identify the cause of your leak will help you in determining what parts of the flushing system that you need to replace. There are two main components that are involved in flushing, and there are different symptoms that occur when each of these components start to fail.
The fill valve is responsible for keeping your tank or cistern with water, so that the tank is full enough when you want to flush. If you’re noticing that your toilet is constantly running, such as a small trickle which you can hear, then it’s likely that you need to either clean or replace your fill valve. This valve sometimes gets clogged, but it doesn’t cost much to replace the entire thing, so whether you clean it or replace it, the choice is yours.
If you are hearing phantom flushes, which is where the toilet flushes or fills without you having done anything, then your problem is with the flapper mechanism. Your flapper and float are responsible for judging where the water level is at in the tank, so if it is getting this information wrong, then your tank will start to fill again. Once your tank is overfull, the only thing it can do to get rid of the excess water is to flush.
How To Repair A Leaking Toilet
If you have a leaking toilet, you may want to replace the fill valve. Here is our step by step guide on how to do that.
Disconnect The Water Supply.
Turn off the water supply by twisting the shut off valve so that it is closed. Flush the toilet to remove all of the water from the tank. Disconnect the supply line.
Remove The Old Fill Valve.
The fill valve can be removed by removing the nut, and then the whole assembly should come right out.
Adjust Your New Fill Valve
Most new fill valves are adjustable, so adjust it by following the manufacturer’s instructions so that the height of the valve is at least one inch above the overflow tube.
Insert New Fill Valve.
Fit the gasket over the fill valve, then insert the valve into the tank. Push down on the gasket, tighten the locknut (but do not over-tighten it) and then reconnect the supply line.
Attach The Refill Tube
You may need to trim the refill tube if it is too long for your system. Once it is the right length, attach the refill tube and angle adaptor to the overflow.
Adjust The Water Level.
With the water connected and turned back on, allow the tank to fill. You now need to adjust the water level by moving the float on the fill valve up or down. The adjustment process may be specific to the fill valve that you use.
Tips And Tricks For Maintaining Your Toilet
There are a number of reasons why your toilet may not be performing, and you might want to try some things before you go through the repairs process. There are many things you can do at home before making a purchase just so you know that you’ve covered all bases.
If you experience water trickling into your tank often, which sounds like a constant hiss, then you might find that the float of your fill valve is getting stuck. You can check to see whether this needs to be adjusted. The refill tube shouldn’t be stuck too far into the overflow tube, so if it’s more than ¼-inch below the rim of the tube, pull it out a little bit.
If you are experiencing phantom flushes, you can empty your tank and check and clean the flapper seat. It may jut require a re-seal, so that it can maintain the seal when you aren’t flushing it. However, if it is worn or damaged you need to replace it altogether.
If you are experiencing a weak flush, then you probably have a clog below the rim of the bowl. You can use a piece of coat-hanger wire to clear out each flush hole, making sure there are no blockages. You can use a mirror so that you can see better.
What To Look For When Buying A Toilet Repair Kit
If you know your toilet needs some work and you want to repair it once and for all, you need to know several parameters before you buy a toilet repair kit. This will ensure that your toilet repair is complete, and that all parts are suited to the type of toilet that you have.
Flush Capacity Of Your Toilet
Older style toilets have a flush capacity of over 3.5 gallons per flush, which is standard in most homes. However, newer builds and installations may have utilized a more eco-friendly approach that uses less water to flush. These low-fill toilets will require a fill valve that can work with these low water levels so be sure to check before you buy.
Fill Valve, Flapper Or Both?
There are many toilet repair kits on the market, and they are built to service either your fill valve, flapper assembly, or both. In order to properly decide which kit you need, you should try to identify exactly where your flushing problem is coming from. If you have a constantly running toilet, then be sure that your kit includes the fill valve. If you’re experiencing phantom flushes, then you will need to replace the flapper. If you’re not sure, a complete kit is the best way to cover all of your bases.
Size Of Your Toilet
The industry standard for toilets is to have a 2 inch water intake hole in the tank. Most universal toilet repair kits are suited to work well with this standard, but some toilet brands have holes that are often larger and sometimes smaller. Be sure to know what size your toilet is configured with so that you can avoid disappointment when you buy your repair kit.
How Many Toilets Will You Repair?
Many homes have more than one toilet, and seeing as they were all installed at the same time, you can expect that the flushing components will break down at the same time. That’s why it may be more cost effective to buy more than one repair kit at any one time. This way, you’ll have enough parts to fix all of your toilets when you need to.
Frequently Asked Questions
Q: Can I buy just any toilet repair kit?
A: No. While many kits are universal and will fit 99% of standard configuration toilets, there are some toilet brands that will use different sizes in the holes. If you have a standard 2 inch system, then you have more flexibility in what you buy.
Q: Can I repair my low fill toilet?
A: Yes you can. Some kits are specifically designed for standard fill toilets, but there are certainly kits that can adjust as low as 1.6 or 1.8 gpf.
Q: How do I know when to repair my toilet?
A: You will know when it is time for a toilet repair. Your toilet will leak, or you will start hearing the tank fill without anyone having flushed it. You may even hear phantom flushes. If your toilet is doing these things, then it’s time for a repair.
Q: What makes my toilet flushing mechanism break down?
A: The water that sits in your tank is pulled in from your main water supply, which is often full of chlorine. This can break down metals and plastics over time, leading to cracking, and degradation of your parts.
Q: My toilet is very noisy after I flush it. Is it broken?
A: It may not necessarily be broken, but you can certainly reduce the noise it makes after you flush. Choose a toilet repair kit that uses a quiet technology to reduce the sound of filling after your flush.
