With “straight” hands, most of the housework can be done independently. This category of work includes the installation of a toilet bowl. Knowing the sequence of actions, installation or replacement can be done by hand.
Types of toilets
In this article, we will consider not the features of the flush or the shape of the bowl, but those design features that determine the list of installation work.
By way of installation
The toilet itself consists of a sanitary bowl and a drain tank. The bowl can be floor mounted or suspended. If the bowl is suspended, then the tank is flush-mounted – built into the wall. In the case of a floor bowl, there are three options for fixing the tank: on a special shelf on the bowl (compact), separate, connected with a flexible hose, in an installation (frame hidden in the wall).
The advantage of a floor-standing toilet with a conventional flush cistern is ease of installation. It can be installed without starting repairs. The disadvantage is that compared to the hanging one, it takes up more space, looks more heavy. Accordingly, the installation of suspended models is complicated – it is necessary to fix the supporting structure – installation – in the wall. Perhaps it is only during the repair.
Release to the sewer
The choice of toilet for release into the sewer depends on the location of the sewer pipe. They happen:
- with horizontal outlet;
- oblique release;
- vertical.
Types of outlets (outlets) of the toilet bowl
If the pipe is in the floor, a vertical outlet is optimal. If the exit is in the floor, but is close to the wall, the oblique toilet is most convenient. The horizontal version is universal. Using a corrugated pipe, it can be connected both to the wall and to the floor.
Installing a toilet bowl with a compact cistern (floor version)
A toilet bowl, a tank, a drain device and a float are usually brought from the store separately. Before installing the toilet, everything except the float must be assembled.
Assembly
The process begins with the installation of a drain device. It comes assembled, you only need to install it in a hole in the bottom of the tank. A rubber gasket is placed between the drain device and the tank.
On the reverse side, the supplied plastic washer is screwed onto the pipe. It is tightened by hand, then – using a key, but very carefully, since it is easy to break the plastic. To prevent the drain device from spinning, it must be held by hand.
The next step is to install the mounting screws on the tank. They are also included in the standard package. These are long thin screws made of galvanized or stainless steel. They are inserted into two small holes at the bottom of the tank, rubber gaskets are put on, then washers, and only then nuts are screwed on.
Before installing the tank on the toilet bowl, a gasket (included) is placed under the tank. To prevent odors from leaking out of the sewer, it must be “planted” on a sealant. First we coat it on one side, put it on the toilet bowl, coat it on the other, put the tank.
We install the tank on the shelf of the bowl, passing the screws into the corresponding holes. We put washers, nuts on the screws from below, tighten them. At the same time, make sure that the tank is level.
Next, we put a float – a device for controlling the water level in the tank. There are two holes in the top of the tank. Here we insert the device into one of them. It is mounted on the side from which the water supply will be connected.
We wind a little flax on the outlet pipe, coat it with sanitary paste, install a corner (brass or stainless). Do not tighten the connection strongly, do not clog that the pipe is made of plastic.
Floor installation
The toilet is almost assembled, you can put it in place. The toilet bowl is connected to the sewerage by means of a corrugated adapter. At the ends, it has rubber seals that fit snugly into the pipes and onto the toilet outlet.
If the sewer pipe is plastic, the corrugation is simply inserted all the way. If the riser is cast iron, and not yet new, so that the smell does not seep through the microcracks, the pipe is cleaned to metal, washed and dried. A layer of sealant is applied around the circumference of dry clean metal (a little more in the lower part), then a corrugation is inserted. For greater certainty, you can go through the sealant on the outside of the joint.
In any case, we insert a corrugation into the sewer pipe.
The second end of the corrugation is put on the outlet of the toilet bowl. This is the connection of the toilet to the sewer. Everything is so simple. There is only one caveat. So that it can be removed later, the corrugation outlet and the outlet of the toilet bowl are lubricated with soap moistened with water, only then the bell is put on. If this is not done, it will be problematic to remove the toilet without damaging the corrugation. But you still have to drill holes for fasteners. It will be much more convenient to remove, rather than trying to move a partially fixed device.
Putting the corrugation on the outlet, we expose the toilet as it will stand. Having installed the lid on the tank, we check that there is a place for it. Next, you need to sit down, check the comfort of use, if necessary, correct the position. Then they take a pencil or marker, inserting it into the holes in the sole, mark the places for installing fasteners.
Having removed the toilet bowl, holes for the dowels are drilled in the marked places. If the kit comes with plastic fasteners, do not use it – it will break in a few days. It is necessary to immediately put powerful dowels.
If the toilet is installed on a tile so that it does not crack, it is better to pierce the glazed surface. They take a self-tapping screw, mark it, hit it with a hammer several times. This is what is called “pinching”. Then they take a drill or a puncher and drill a tile, turning off the impact mode. After the tile is passed, you can turn on the perforation mode.
We put plastic plugs from dowels in the holes. They must be in the same plane with the floor. If there is a thicker edge, cut it off with a sharp knife.
We sweep the floor, removing dust at the installation site of the toilet. We put it in place, insert the dowels into the holes, twist them with the appropriate key. It is necessary to tighten the bolts alternately on one side, then on the other. Tighten until the toilet becomes firmly, without play.
The final touch is the connection to the water supply. Connect the outlet of the water pipe to the tap installed on it with the corner on the tank, which was connected earlier. This requires a flexible hose. At its ends there are union nuts (American), so there will be no problems with fastening. Tighten well, but without fanaticism.
Next, they put the lid on, install the release button, make a test run of water. If a drop is found somewhere, tighten the connections. That’s all. Do-it-yourself toilet installation is completed.
How to install a wall hung toilet with installation
To install hanging toilets, the outlet of the sewer pipe must be located near the wall. The specific distance from the wall is indicated by the manufacturer, but it should be small – from the far edge of the order of 13-15 cm. If the exit from the floor, there is a solution – a special overlay with which the drain is transferred closer to the wall.
The installation of a wall-hung toilet begins with fixing the stops to the wall to the installation frame. They are attached two at the top and at the bottom. With their help, the distance to the wall is adjusted, the frame rises and starts.
The upper stops are in the form of rods, adjustable with a socket wrench and a screwdriver. The bottom stops are more like plates, they are also adjusted with a socket wrench but with a side head.
The assembled frame is attached to the wall, its center is exposed above the middle of the sewer outlet. The mark on the frame rises or falls to the height required by the manufacturer (there is a mark on the frame, also indicated in the passport, usually 1 meter).
Using a bubble level, the horizontal and vertical installation of the wall-hung toilet installation is checked.
By adjusting the height of the stops, an equal distance from the wall, set by the manufacturer, is set. How convenient it is to do, look at the photo.
The exposed frame must be fixed to the wall. In appropriate places put marks with a pencil or marker, drill holes. They are equipped with plastic housing dowels. Most of the hanging toilets are imported, and they recommend planting the dowel bodies on the sealant. Some of the sealant is squeezed into the drilled hole, a dowel is inserted. Then, before installing the fastener itself, the sealant is applied to the plastic case.
In a fixed installation, you can put connecting elements – branch pipes, couplings. They are all included and simply snap into place.
Next, metal rods are installed on which the toilet bowl will be held. They are screwed into the corresponding sockets, silicone seals are put on top (in the lower photo these are two rods above the sewer outlet).
The sewer pipe extends to the desired distance, is fixed in a predetermined position with a bracket. It covers the pipe from above, is inserted into the groove until it clicks.
Next, water is connected to the tank. Open the tank lid (it is latched), the plug on the side surface is removed. Right or left – depends on where you have water. A corrugated pipe is inserted into the opened hole, the counterpart is inserted from the inside, everything is connected with a union nut. It is necessary to tighten without applying excessive force – it is plastic.
A tee is installed inside the tank, a pipe (usually plastic) is connected to the desired outlet. They do this with the help of an adapter and an American.
A hose from the tank is connected to a special tee inlet. It is flexible, in a metal braid. Tightened with a cap nut.
Install the cover in place. In principle, the installation for the toilet is installed. Now we need to close it. To do this, make a false wall of moisture-resistant drywall. It is recommended to put two sheets, but you can use one. Drywall is attached to the installation frame and to the mounted profiles.
Next, the wall is finished, after which the toilet bowl is hung and a decorative panel of the drain device with buttons is installed.
The toilet bowl is put on the pins, its outlet goes into the plastic socket. The connection is tight, no additional measures are required. This completes the installation of the toilet with the installation.
