Toilet Installation
(WC) INSTALLATION in Bathrooms
|
Here
we offer general instructions and precautions for roughing in, as
well as installation procedures for tying into your present drain
waste vent and supply systems.
When all the
roughing in has been completed and you are ready to assemble your
toilet, your rough plumbing should resemble that shown here.
Most Common
Mistakes
- Violating or ignoring local code
restrictions.
- Using pipes that are too small.
- Attaching copper to galvanized without
using a brass or dielectric fitting between the two.
- Not using Teflon tape or pipe compound at
threaded joints.
- Not leveling your fixtures when installing
them.
- Not installing an air gap filling for
fixtures.
- Cutting supply stub outs too short to
install the shutoff valves onto after the finished wall is in place,
or

Not properly aligning tubing into fittings
or stop valves. (Forcing the nut onto the compression ring at an
angle when the tubing is at an angle will cause a leak.)
When turning the water back on in your
home, always run the outside hose valve or flush your toilets to
bleed dirt and air from the lines. This debris can cause problems in
your sink faucets and other plumbing trim.
Installing Your Toilet in your
Bathroom
Suite
 Pipes required include a cold water supply
stub out with a shutoff valve, flexible tubing for above the valve,
and possibly one air chamber.
This is possibly the single, most troublesome
fixture to install as it requires its own 2" minimum vent and a drain
of at least 3" in diameter. If the toilet is situated on a branch
drain, it cannot be upstream from the sink or shower. The minimum side
distance allowed from the centre of the toilet bowl to a wall is 15
inches 12 inches to a bathtub, and clearance from the front of a bowl
to a wall or fixture should be 21 inches.
1. The closet bend and toilet floor flange
must be roughed in first. When replacing a toilet, you will need to
scrape up the old wax gasket. A putty knife works well for this.
Remove the old bolts from the floor flange and scrape the flange clean
to prevent leaks at the base of the new bowl. If the old flange is
cracked or broken, replace it with a new floor flange.
2. Position the floor flange so that the
underside of the flange is at the level of the finished floor. (it is
always best to install the finished floor so that it runs underneath
the toilet.) You may need to use a piece of finished flooring material
if the floor has not yet been installed. Now you can finish tightening
the screws that hold the floor flange to the floor. Put a small level
on the flange while tightening to be sure it is level.
3. Set the new floor bolts in plumber's putty
and insert them through the flange, adjusting the bolts so they line
up with the centre of the drainpipe.
4. With the new toilet bowl turned upside
down, position the new wax gasket over the toilet horn on the bottom
of the bowl.
5. Apply plumber's putty around the entire
bottom edge of the bowl.
6. Using the bolts as guides, lower the bowl
into place over the flange. Press down firmly while giving a slight
twist. It is important that you feel the toilet being pushed into the
wax ring. If you do not feel this, the flange is set too low and you
will not get a good wax seal between the flange and the horn (waste
outlet). Also, if the wax ring is cold, it will not properly seat. You
may need to warm it in the sun for awhile until it is pliable.
7. Use a level to level the bowl, adding shims
where necessary. Also be sure the toilet is square and aligned with
the wall. Then tighten the nuts and washers onto the bolts by hand.
8. Place the rubber tank cushion (if one is
needed) into position on the rear of the toilet's bowl and fit the rubber
gasket onto the flush valve opening on the bottom of the tank.
9. Position the tank over the bowl; then
tighten the nuts and washers onto the mounting bolts.
10. Tighten the hold-down bolts at the base of
the bowl with an adjustable wrench. Use your level to assure the bowl
is still level.
11. Fill the decorative caps with plumber's
putty and place them over the bolt ends. Seal the base of the toilet
bowl with plumber's putty or silicone caulk.
12. Cut the end of your supply line stub out
and attach a shut off valve. Then, connect the shutoff valve to the
flexible tubing and connect the tubing to the bottom of the tank,
where you will find a supply stub out.
