Many decide to install a shower instead of a bath. It is necessary to do everything right - and sewerage, and thermal insulation, and waterproofing, and a drain ladder. The latter is also important. Many, doing repairs themselves, do not even know what it is.
Value of fixture
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 a tight joint with the floor.
- Produces filtration of wastewater from strong pollution, prevents frequent blockages in the sewer.
- Allows you to clean the drain system.
- It has a water seal that prevents the penetration of stale air.
Drainage drains are made of anti-corrosion metal and durable plastic. When buying, you need to pay attention to the design - it must be strong, durable, not violate the tightness 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 drain is important when installing a shower, as this indicator determines the height,to which you need to raise the level of the floor.
What is a ladder, we figured it out, now you need to understand how it is installed. This is a housing with a flange that hermetically fixes the floor membranes. A siphon with a grate is installed in it, which allows you to create a water seal and protect the sewer from blockages. Before buying a ladder, you need to make sure that it will fit in height, and also does not have any defects.
Gangway installation
When installing the described device, you need to understand that you will have to raise the floor in the shower. Also, the floor is laid with a slope so that the water flows towards the drain. Usually it is raised to 15 cm, there is nothing catastrophic in this. The floor structure is laid in a multilayer system:
- EPS sound and heat insulation (approx. 5 cm).
- Concrete screed (about 4 cm).
- Laying waterproofing material.
- Concrete screed with a slope towards the drain (approximately 4 cm).
- Ceramic tiles that do not absorb water.
It turns out that the ladder with the shutter is solidly immured in the floor. The main thing is that its grate does not protrude above the tiles.
Drainer Making Guide
Having de alt with the question of what a ladder is and how it is installed, you can move on to creating a device. Before starting work, 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 notbe above the tiles. The minimum slope of the drain is 1 cm, if you make it less, then the water will drain very slowly.
The ladder from the wall is set according 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 stresses and movements constantly occur, and this can damage the waterproofing. It is better to play it safe and glue all the corners with sealing tape. For reliable protection against water penetration, it is recommended to first lay the tiles 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.
