How To Install A Toilet Repair Kit

by TimJones on March 18, 2010

Oftentimes, we need to replace the internal components of our toilets.  The plastic and metal parts wear out and need to be replaced for the toilet to function properly.

Fortunately, this is an inexpensive and easy home improvement project.  Most hardware stores carry a “toilet repair kit” that costs around $18-20 that includes all the components you’ll need for this project.  In fact, you’ll have some parts leftover, because the kits come with lots of parts to cover various types of toilets you may be using with the kit.

As noted in the video, you need to start by tearing the old components out of the toilet.  Of course, you’ll do this after shutting off the water supply — typically a valve right next to the toilet, close to the floor.

Once the old parts have been removed, there will be some necessary clean-up, especially where the tank attaches to the toilet base.

Now, you just need to install the new parts from the toilet repair kit.

This is a fairly easy DIY project that may require a second person, just because the toilet tank can be somewhat awkward to move.

What challenges do you have with your toilet?  Leaking flapper valve, running fill valve, etc.?  Let us know your toilet issues in the comments section and we’ll do a new post!

Great video! Worked a charm. Thanks.

Hey Tim,

This was definitely helpful and I decided to tackle this on my own. It did take me about 3 hours as it was my first time and I didn't have an adjustable wrench large enough for the nut on the base of the tank. I have one question about the bolts though. My kit had an extra set of hex nuts and washers that were supposed to go between the tank and the base. I felt like there should have at least been rubber washers between the tank and the base, but your video implies you don't need anything here. What are your thoughts on this?

Hey Dave,

Thanks for the comments! Every toilet is different and these kits are “universal”, so you will always have parts left over. The toilet in the video may not have had the washers that might have been in yours. I always follow whatever I take out — basically, copy what was already there. Sometimes you do need those washers to keep from cracking the tank or base, but sometimes you don't.

Hey Tim! Thanks! I couldn’t have done this without your video. Worked like a charm!

Aloha Tim!

I’m using the same brand kit as your video. One thing that make me nervous is the fact that this kit seem to come with a rubber gasket that mates the tank to the toilet seat that’s too tall. So basically, the tank does not contact the raised portion of the seat at the front or the back. I did place some of the left over rubber gasket in the back so there’s contact in the back but there’s no contact in the front. I tightened the bolts evenly so the tanks does sit evenly and there’s very little movement. Also, there’s no leak. But this still makes me nervous. I had leaking toilet once and it cost me $$’s to have my home repaired and I really do not want to go through that again. What are your thoughts?

I hope you understand what I’m talking about..but in mean time, I’ll try and look for another brand that “fits” better. Thank you.

Just an update… The rubber gasket that mates the tank to the toilet in this replacement kit is just fine. I believe I’m using a bit too much finesse. If I use the wing nuts to connect the tank to the toilet, the tank will land nicely on the toilet — evenly hand tightened that is..

BTW, I have American Standard Elongated Toilet.

the gasket on the new flush valve assembly leaks like crazy…I did assamble it correctly, cleaned all surfaces, etc…Can I just silicone it and call it good ?

@mark It sounds like you may have an issue with the toilet, itself. Provided the gasket is installed properly, I would look for cracks in the toilet. It could even be a hairline crack that’s hard to see that may be causing the leak.

I am going to have to replace all of the guts of my 15 yr old low flow toilet. Thank you for video–very helpful info. Believe I have a leaking, running fill valve; so I already shut water supply off @ floor. That worked for a few days. Now when I turn the water supply valve off, I can still see & hear water leaking into toilet and hear it from actual water supply valve & line. How do you replace the shut off valve faucet handle or what do I need to do? I have been shutting off main water shut off valve when leaving for work. Have to wait until my next day off to get toilet repair kit & replace. Or should I just replace with a newer model toilet & get it over with. Thank you!!
