If you find that your toilet is not flushing properly, the first thing you should do before calling a plumber to come and fix it is to replace your tank. If you are looking for an easy way to do this, look no further! Here is a fast and easy toilet tank replacement guide that will show you step by step how to change out your broken or leaking toilet tank in just 10 minutes.

When You Should Replace Your Toilet Tank?

You have to know when you should replace your toilet tank. The most common reason to have a leaking toilet is that the tank has cracked or broken, and if this happens then you’ll need to replace it right away!

How To Replace Your Broken Or Leaking Toilet Tank?

To save time, buy an entire replacement kit rather than just the parts themselves. Purchase only one new part -the tank- because everything else will be reused from the old unit. Take out all of the bolts connecting the water supply lines; these are usually on either side at the top of where they go into each other for them to connect properly with no leaks. Then disconnect any hoses attached by unscrewing their connection points (this may require a wrench).

Well, just follow these steps:

  • Gather all your materials: toilet tank, new sealant or adhesive, wrench, and a towel to catch the water. Make sure you have one of those old-fashioned toilet plungers handy too!
  • Place an old cloth under the base of the toilet if it’s on carpeting so that no dirt from the floor gets into your plunger. You can also use painter’s tape for this purpose as well.
  • Remove any existing bolts with a wrench by turning them counterclockwise using pliers if they are stuck tightly in place. Be careful not to damage anything when removing them. If there is rust buildup where these bolts connect to metal parts of other pieces inside the tank beneath then remove them carefully without hammering away at them.
  • Place a towel under the tank to catch any drips and use an old cloth or paint scraper to get rid of dirt from underneath it as well. If you have a toilet bowl cleaner, use this on the base before replacing your new sealant!
  • Put some sealant onto the bolts (apply with long strokes) and screw them back in tightly. Replace your toilet seat after doing so because if water spills into where these connections are then this will cause more rusting over time that can lead to leaks which are bad for everyone’s pipes! Don’t forget about those nuts either while you’re at it…
  • Turn off the water valve until you’ve finished installing your new toilet tank!
  • The next step is to turn on the water valve and close it off again. This needs to be done in order for your tank to fill up with water so that you can test for leaks!
  • If none are found, congratulations! You’re finished and ready to start using your new toilet tank replacement kit!

Toilet Tank Replacement Tips

Here are some tips on how best to replace your toilet. These includes:

Test for leaks by slowly turning off and opening the water valve all at once– this will cause it to fill up and any potential leak should be detected immediately. You may also want to check under where the base meets the floor as well because sometimes they’ll drip out from there too. If no leaks were found then congratulations! It’s time to get started.

If you’re replacing a toilet that doesn’t have an overflow pipe, make sure your new tank has one in the right place – it should be towards the front and not at either side of the bowl (the water will drain out).

When installing, use appropriate adhesive on all joints– this is important because if there’s no sealant then any potential leak could cause serious problems or even damage floors!

A good idea is to temporarily cover up other plumbing with old newspapers or something else so they don’t get dirty from debris when taking apart the toilet. You can also close off just under where things are connected to ensure nothing falls inside before starting the removal. Toilet tanks usually need some sort of lubrication also.
