How to replace a toilet
A
toilet that doesn’t flush well can turn what should be pleasant personal time
into a shaming, stressful experience. A plunger at the ready by the side of the toilet is of course a
thoughtful touch in any bathroom, but all too often it’s an indication of
deeper problems. Fortunately,
replacing an old toilet is a straightforward procedure, and with common sense
and a few basic hand tools almost anyone can do it.
The
first step is to select a new toilet. Make a checklist of features you like, then ask friends and neighbors
for recommendations. Check out
consumer guides. Start paying
attention to what’s out there (or, more accurately, under you). Look for quality. Too many homeowners just buy whatever’s
on sale and then end up right back where they started, struggling to flush even
insignificant movements.
Unpack
the new toilet and inspect it as soon as you get home. If it’s defect-free strap on your tool
belt, turn the water off and roll your sleeves up. Flush ‘old unreliable’ one last time and then sponge out any
water left in the tank and bowl. Cram the sponge deeply down into the bowl to get all the water out. This may seem unpleasant but giving in
to queasiness now will lead to disabling feelings of revulsion later, so plunge
ahead.
Disconnect
the water supply line from the underside of the toilet and look inside the
tank. Two large bolts with rubber
gaskets hold the tank to the back of the bowl, and to undo them you need to
reach in the tank with a screwdriver and hold the bolts in place while
loosening the corroded nuts under the water tank. This may sound hard, and in fact it is.
Next,
remove the nuts holding the toilet bowl to the floor and yank the bowl up. Underneath you’ll see a dark hole with
thick goo around the rim. This is
the waste line, the portal to the main sewer or septic field. It will smell, so stuff a rag down into
it quickly.
Scrape
up the goo - the gummy remnants of the wax ring used to seal the joint between
the bowl and the toilet flange. Wax rings are the last line of defense in the waste removal system,
preventing flushage and odors from exploding out onto the bathroom floor. Scientists estimate that the average
American family uses their toilet 32.6 times a day, and one could easily believe
that the mess smeared on the floor under the old toilet was some dreadful
residue of all that hard use. But
it’s not. (Believe me, memory and imagination
are a plumber’s worst enemies.) Still, there is
some danger of sepsis (a potentially life-threatening medical problem) if you
accidentally scratch your hand while scraping, since an open wound would create
an easy pathway into your blood for toxic bacteria.
Frankly
though, it’s the next step that rarely goes well for me. But I’m sure it will for you, and I don’t
want to scare you away from this simple home improvement project by talking
about every little problem that might occur.
However,
if the floor and the surrounding joists under the toilet do turn out to be
rotted from years of leaking - to take one common for-instance - simply remove
all weakened subflooring and the finished tile floor resting on it (in some
cases also the bathtub and vanity), install temporary support walls in the
basement under the rotted joists, cut out the damaged sections, re-route any wiring, plumbing and heating running
through the joists (bringing them up to code if necessary), jack up the floor
with a hydraulic jack to correct any settling, splice on new joists, lay down
new subflooring, retile and grout the floor, then reinstall the fixtures.
Presumably
the main waste line running through the house and out to the street is in good
shape, with no leaks or cracks of the kind that can secretly cause thousands of
dollars in damages, but of course it’s difficult to know.
Finally,
clean up the mess and unpack the new toilet. You’re almost done!
The
rest of the installation is simple enough and needs little explanation. Just repeat what you did to remove the
old one, except in reverse. Consult the manufacturer’s directions if you become confused.
Incidentally,
the first flush after you fill the new tank may seem sluggish, but this just
means you forgot to remove that rag you stuffed into the waste line. Have a laugh – then drain and remove
the new toilet, pull the rag out and reinstall everything.
Remember,
though, to put a fresh wax ring on the bottom of the toilet every time you
reinstall it. Without a perfectly
sealed wax ring toxic sewer gas can vent out and silently fill your entire
house while you sleep. And
unfortunately under certain circumstances this can kill you.
