Having a functioning toilet is a mandatory requirement for any residential or commercial space. Many consider the process of installing a toilet complex and requiring professional plumbing help. However, by following detailed instructions and using the necessary materials, this task can be performed DIY.
Required Tools and Supplies
For installing a toilet, you will need: a rotary hammer/drill, a set of concrete drill bits of 10-12 mm diameter, a hammer, a level, an adjustable wrench, pliers, Phillips/flathead screwdrivers. Consumable materials include: sanitary silicone sealant, plastic anchors of the appropriate diameter, flushing hardware (flexible 1/2-inch hose), corrugated sewer pipe of 100-110 mm diameter no less than 50 cm long, rubber sealing gaskets.
Preparation
Remove the old toilet, noting the types of water and sewage connections to select the new one. Check the water valve, replace if worn. Prepare the sewage opening: clean off remnants of the old toilet and gaskets. Cover the opening with film to prevent the spread of odors.
Decide on the type of toilet: floor-standing (compact) or wall-hung (with a concealed tank). Installing a wall-hung toilet is more complex, requiring the installation of a mounting frame and finishing. For a floor-standing toilet, choose a model with an outlet matching the location of the sewage opening: vertical (hole in the floor), horizontal (flush with the outlet) or oblique (other cases). The water supply to the tank can be side or bottom - choose depending on the location of the water pipe.
Marking and Preparing the Location
Ensure minimal distances: 60 cm in front of the toilet for comfortable use, 20 cm behind and on the sides for maintenance. Level the horizontal surface of the floor, using cement screed or joists if necessary. Mark the installation location: insert the corrugated pipe into the sewage opening, position the toilet bowl with a gap of 2-3 cm to the pipe, outline and mark the holes for the mounting bolts.
Assembly and Installation
Following the manufacturer's instructions, assemble the toilet bowl with the flush tank, installing rubber gaskets on all connections for tightness. Move the toilet aside, drill holes 2-3 mm larger than the anchors in the marked places, insert the anchors. Set the bowl in place through the corrugated pipe and secure to the floor with anchor bolts and washers. Stretch the corrugated pipe over the outlet and secure with clamps. Connect the water hose to the tank.
In tight spaces, it is recommended to first connect the corrugated pipe to the sewage, then attach the bowl to the floor, and then assemble and install the tank.
Final Stage
Adjust the water level in the tank according to the instructions, performing test flushes. Too high a level will lead to water wastage, too low will result in poor flushing. Check all connections for tightness, treat with silicone sealant if necessary. After final adjustment, neatly secure the rear cover on the tank.
Following this detailed guide, you can perform a high-quality professional toilet installation yourself and gain invaluable practical experience.
Safety Tips
When installing a toilet, it is important to observe safety measures to prevent injuries and damage. Always wear protective gloves when working with drills, a drill, and other sharp tools. Wear safety glasses to prevent dust or small particles from getting into your eyes while drilling holes. If working on your knees, use soft knee pads for comfort.
When working with power tools, ensure they are in good working order and properly grounded to prevent electric shock. Never leave tools powered on unattended. Keep the work area free of foreign objects and ensure good lighting.
Common Problems and Their Solutions
Leaks - one of the most common issues after toilet installation. Ensure that the sealing gaskets are properly installed and evenly tighten all connections. Apply silicone sealant for additional sealing.
Incomplete flushing may be caused by improper water level in the tank. Adjust it according to the instructions to ensure sufficient pressure.
Constant water running from the tank may indicate a malfunction of the flushing mechanism. Try adjusting or replacing worn parts, such as the float or valve.
Toilet instability caused by uneven flooring or incorrect marking of mounting holes. Check the attachment of the bowl to the floor and use additional anchors if necessary.
Care and Maintenance Recommendations
To extend the life of your toilet, follow simple care rules. Regularly clean the bowl and tank with mild cleaning agents or a vinegar and water solution, avoiding abrasive substances. Promptly remove lime scale and rust.
Avoid introducing foreign objects, hair, paper, food waste, etc., into the tank and bowl. This can lead to clogs and damage to the flushing system. When replacing gaskets and other rubber parts, use only original spare parts.
If you encounter problems that you cannot solve on your own, seek help from a professional plumber.
