Many decide to install a shower instead of a bathtub . Everything needs to be done correctly — sewage, and thermal insulation, and waterproofing, and a drain ladder. The latter is also important. Many, making repairs themselves, do not even imagine what it is.
Device Value
What is a ladder? This is a complex plumbing device. It provides not only the discharge of water into the sewer, but also performs other functions:
- Provides tight joint with the floor.
- It filters wastewater from heavy pollution, prevents frequent blockages in the sewer.
- It makes it possible to clean the drain system.
- It has a water lock that prevents the penetration of stale air.
Drain ladders are made of anticorrosive metal and durable plastic. When buying, you need to pay attention to the design - it must be strong, durable, not to violate the integrity of the floor. These devices can be either with one branch pipe or through passage, have different heights. It is important to know that the height of the stairs is important when installing a shower, since this indicator determines the height by which you need to raise the floor level.
What is a ladder, we figured out, now we need to understand how it is installed. This is a housing with a flange that seals the floor membranes. A siphon with a grate is installed in it, which allows you to create a water lock and protect the sewer from blockages. Before buying a ladder, you must make sure that it fits in height, and also does not have any defects.
Gangway installation
When installing the described device, you need to understand that you have to raise the floor in the shower. Also, the floor is laid with a slope so that the water flows down towards the drain ladder. Usually it is raised to 15 cm, this is nothing catastrophic. The floor structure is laid on a multilayer system:
- Sound and heat insulation made of polystyrene foam (about 5 cm).
- Concrete screed (approximately 4 cm).
- Laying waterproofing material.
- Concrete screed with a slope towards the ladder (about 4 cm).
- Ceramic tile that does not absorb water.
It turns out that the ladder with the bolt is seamlessly walled up in the floor. The main thing is that its lattice does not protrude above the tiles.
Drain ladder manual
Having figured out the question of what a ladder is and how it is installed, we can proceed to the creation of a device. Before you begin, you need to set the thickness of each layer of the floor. The lowest point of inclination is determined by the height of the ladder: by changing the thickness of the concrete screed, you can choose the desired height, but the ladder should not be higher than the tiles. The minimum slope of the drain is 1 cm, if you make it smaller, then the water will merge very slowly.
A ladder from the wall is installed to the size of your tile. It is best to lay the material from the ladder to the wall. The seam between the tiles should be no more than 2 mm. Installing a ladder according to the above algorithm will reduce the number of tiles to be cut, the floor will be much more beautiful. All corners are considered problem areas where tensions and shifts constantly occur, and this can damage the waterproofing. It is better to play it safe and glue all corners with sealing tape. For reliable protection against water penetration, it is recommended to first lay the tile on the floor, and then on the walls. Knowing what a ladder is and how to install it correctly, there will be no problems during work.
