How to replace a toilet: dismantling the old one and installing a new one with your own hands

How to replace a toilet

Installation of plumbing equipment is carried out in strict accordance with building codes and regulations. Home craftsmen are often afraid of such work. This is used by service companies that charge quite decent money for performing fairly simple operations. Meanwhile, fastening the toilet bowl to the floor is an exercise that is quite accessible for self-fulfillment. It is only important to carefully familiarize yourself with the existing work technologies, choose the most suitable one, and follow all the instructions exactly. If toilet cistern still running after flushing, Regardless of the chosen method of fixing the toilet, installation work begins with the assembly of the cistern. The device is assembled in accordance with the instructions and fixed in the place intended for it. Also, before installing the toilet, the water supply and drainage units must be prepared. There are several methods for attaching devices. The main selection criterion is the floor material on which the equipment will be installed. Let’s take a closer look at the most common methods.

Method number 1:

Installation on dowels the most practical method to install the device with the least effort and time. Ideal for use on a flat, smooth surface, since the slightest height differences negatively affect the flush quality. It is preferable to use this method of fastening for lightweight compact structures, since the fixation may not be entirely reliable. Plumbers advise to install the equipment on a special gasket, which can be easily made by yourself from old linoleum or a sheet of thin rubber. The toilet is installed on the work piece, traced around the contour with a marker. After that, a gasket of the desired shape is cut out with a sharp knife or just scissors.

Now you need to markup. We “try on” the toilet bowl on the place prepared for the equipment and draw a circle around it. We remove the device. We apply a thin layer of sealant and glue a gasket on it. This design will be the most reliable, although some craftsmen prefer to do without a substrate at all. You can start drilling the holes for the fasteners. As practice shows, if you stick the gasket well and choose the diameter of the drill so that the holes for the fasteners are slightly larger than it, then further installation will be much easier. This is due to the fact that the rubber substrate acts as a kind of “contact spot” for the floor and the device. It happens that you need not only to fix the toilet bowl to the floor, but also to raise it a little. This is true if there are several devices in the apartment. Then the last one in the system needs to be raised by about 3-4 cm. In this case, a piece of a two-inch board is used, which is used as a stand. It is cut exactly to the contour of the toilet and placed on the floor with a rubber backing on top of it. All this is sealed with a sealant and forms a reliable and durable structure. We drill holes for fasteners directly along the gasket.

Long metal dowels or special plumbing fixtures can be used as fasteners. The latter usually come with new equipment. Their fastening quality is about the same, so you can use both options. We drive dowels into the holes prepared in the floor. We install the toilet and carefully screw it on. It should be borne in mind that if tightened too tightly, the ceramic from which the device is made can be damaged.

Now you need to connect the device to the sewer. At this stage, we pay special attention to the corrugation. Liberally lubricate both edges with silicone. We insert one of them into the sewer socket, and put the second one on the toilet bowl outlet. All joints should be carefully pressed with your fingers so that the seal is good. As an additional measure, you can use metallized tape, which can be used to seal the joints. We connect the water supply and the device is ready for use. There is a similar mounting method, which is detailed in the video.

Method number 2:

Mounting on glue Of all the methods for fixing the toilet to the floor, this is the simplest, but at the same time, the most time-consuming. It takes about 12-15 hours to cure the epoxy mixture, which is used as an adhesive. This method can only be used on a smooth surface. It is most commonly used to secure equipment to floor tiles. The method is very simple to implement. First, both surfaces to be glued must be well cleaned of dust and debris. Floor tiles can be brushed to roughen them up. This will improve the adhesion of the material. Surfaces can be degreased with any solvent or acetone. Cooking glue. You can buy a ready-made epoxy compound or make it yourself. To do this, you need to take 100 parts of ED-6 epoxy resin, 200 parts of cement, 20 parts of a solvent or plasticizer and 35 parts of a hardener. The sequence of adding components to the solution is important. First, the resin is heated to 50C, a solvent is added to it, after a hardener and at the very end – cement. The composition must be constantly mixed in order to form a plastic, homogeneous mass.

A properly prepared adhesive mixture can be used within an hour and a half. We apply it to the base of the toilet bowl so that the solution covers an area of ​​at least 20 square meters. cm, and the layer thickness was at least 4 mm. We install the prepared equipment in the right place, combining the sewer bell with the outlet, and press it with force to the floor. Then leave the device for at least 12 hours. This period is necessary for the adhesive to harden. During this time, it is not recommended to even touch the toilet. Then we connect the equipment to the water supply and sewerage system.

Method number 3:

Fastening to taffeta Most often, this method is used to install toilets on a wooden floor. Taffeta is a solid wood pad to which the equipment is attached. The thickness of the board from which the element corresponding to the shape of the toilet seat support is cut should be 28-32 mm. To protect the part from dampness, it must be carefully treated with linseed oil. For reliable fastening to the floor, anchors are mounted from the bottom of the taffeta. The simplest option is nails driven in a checkerboard pattern, which should protrude from the part by 2-3 cm. The recess prepared for installing the toilet is filled with cement mortar. Taffeta is embedded in it down with anchors. As a result, it should be flush with the floor. After about 12 hours, during which the solution is completely dry, you can start attaching the equipment. The device is fixed with screws. Washers made of rubber must be placed under their heads, which will prevent possible damage to the toilet bowl when tightening. Experts advise to lubricate the screws with grease or graphite before work, so that later, if necessary, they can be easily unscrewed. Wood taffeta can be replaced with rubber backing. It is cut from 5 to 15 mm thick sheet material, perhaps even from an old rubber mat. This substrate should be 1 to 2 cm smaller than the toilet seat support.

There are many ways to attach a standard toilet to the floor. They differ significantly in complexity and time spent on installation work. It is important to choose the correct fastening method. It depends on the material from which the floor in the room is made. Installation work can be carried out independently, but if you have no experience or desire, it is better to turn to professionals. They will quickly and competently carry out all the work, guaranteeing a long and flawless service of the new equipment.
