How To Replace and Install a Toilet

So it’s time to replace your toilet… I know,
it’s probably not your favorite job, but hey, it’s easier than you think. To start, most new toilets come in standard
sizes that can be easily swapped out. But, if you’re in an older home it’s a good idea
to check first. Just measure the distance between the closet
bolts and the wall—not the trim, the wall—to make sure it’ll fit. And for tight spaces,
measure to the side walls. Take these measurements to Lowe’s to make sure you get a toilet that
fits your bathroom. Once you have your new toilet you can pull
out the old one. Now we’ve been remodeling this bathroom. We took out our old toilet
before we removed the old tile. Here’s what to do. Turn off the water supply. Then flush and
hold the handle to drain the water from the tank. The little bit of water left in the
bowl can be removed with a plastic cup or sponge. Next, disconnect the water supply
from the tank, and remove the nuts from the closet bolts. Now the old toilet is ready to come out. You
can set it in a garbage bag before you take it away. With the toilet gone, place a rag
in the drain to block sewer gases. Then use a putty knife to clean off the old wax ring.
If the closet flange is rusted, replace it. Ok, now it’s time to install the new toilet.
Insert new closet bolts in the flange if you haven’t already. To prep the bowl, gently
set it upside-down on a cloth and lightly press a new wax ring over the outlet. Ready for installation. Now you can remove
the rag from the drain. Line up the toilet with the bolts and lower
it. Press down around the toilet to seal it against the drain. Make sure it’s square to
the wall. Place the cap base, washers, and nuts on the
closet bolts. Tighten them, but not too tight, you might crack the toilet. Alternate between
each side as you go. If the closet bolts are too long for the caps, carefully cut them
with a hacksaw, then put on the caps. Bowl’s in. Now with two-piece toilets, the
tank goes on in almost no time at all. Most new toilets have the flush assembly and handle
installed, but if yours doesn’t now is the time to do it. Then, install the bolts and
rubber gasket. Set the tank in place and secure it with the nuts. Just hand tighten them for
now. Check that it’s level, then tighten the nuts just enough to make a watertight seal. We’re in the home stretch. Install the flush
handle according to the directions. Connect the water supply and slowly turn on the water.
Check for leaks around the supply lines and gasket, and make adjustments if you need to.
Then attach the seat. Flush the toilet a few times and look for leaks around the base.
Seal around the base with latex caulk. Set the top on the tank—and you’re done.
That wasn’t so bad. We’ve still got some work to do in this bathroom,

  1. There was only one tip that they got wrong. Do NOT caulk around the base of the toilet. If the wax ring leaks, it will cause the floor to rot andΒ the toilet will fall through the floor (usually with someone setting on it). I have worked as a plumber for over 20 years, and it was on a test that we took to get our license. Almost everyone failed this issue. FYI.

  2. We have a toilet that keeps leaking water down into the bowl from the tank so it runs every hour or so to fill back up. I've replaced the flapper twice now but even with a new one it doesn't seal.I used the flapper that came with the new "guts" and last time bought just the flapper that was recommended for that toilet… Any other tips?

  3. My house was built in 1983 and my flange broke and the toilet rocks freely. Totally best to check first. I am not replacing the toilet

  4. as a licensed plumber you never! silicone the bottom of the toilet very poor practice and you should tell people to do that cause if the seal wears out the water goes through your ceiling and not onto the floor where you can see it!

  5. I have installed 10s of toilets (not hundreds) and I have never used a rag to stop "the gasses", I just open the window and soldier on with the smell. Then again I'm a real man

  6. 1:50 Tight, but not too tight! Thats why Plumbers get paid the big bucks! Something as Simple as over tightening flange bolts will Crack your new toilet! Eek!

  7. There should be an initial comment, that all the repairs, and installations are done with optimal conditions. As in repairs are done on brand new fixtures. All installations, are done where existing plumbing is not in need of some form of repair, or replacement, due to age, or deterioration. Try turning the shut offs in a 60-70 year old house. Even the main water shut off could snap off in your hand !! Taking a trap apart that has a large amount of corrosion on it !

  8. Many cities will not pick up the old toilet when placed out at the curb, Does Lowe's have a toilet recycling program?

  9. In all of the videos I've seen on the toilet installation, the installer inserts the wax ring onto the toilet flange. You have to be careful that you don't poke the wax ring when you lower the toilet.

  10. Why do so many tutorials suggest you place the wax ring down first and aim to land on it? This tutorial is easier with you pressing the wax ring against it first. Bonus question: do the new types of rings that arent made of wax work? If they do, why do people even still use these things. I just hate that mess.

  11. The 2 washers were just set on the flange with no nut.? You should use 2 washers and 2 nuts per blot, but if 1, the washer on top of plastic washer ABOVE the toiler.

  12. With the door to the right and the shower to the left, where would the person using the toilet grab toilet paper?
