Can you change the floor drain yourself? Method introduction

Everyone has a floor drain at home. Floor drains are generally installed underground in bathrooms and kitchens. The floor drain exists to prevent the sewer from clogging. When installing a floor drain, professional workers are generally needed to install it, because the installation of the floor drain is generally integrated with the building decoration. Most people's floor drains are installed together during decoration, but some people's floor drains have been used for a long time and need to be replaced if they are damaged. We can also replace the floor drain ourselves. Let's take a look at the tutorial of replacing the floor drain ourselves.

The floor drain can be changed by yourself.

First, the replacement method

To replace the floor drain, first remove the cement around the floor drain with slotted screws, then tap the floor drain with a small hammer to separate the floor drain from the cement below, and then take it out. This is the old floor drain that was removed. Attention, everyone! The floor drains on the market are basically this kind of water-sealed floor drains, and the water seal is very shallow, which can't achieve the deodorization effect at all. Clean the cement layer around the floor drain pit with a chisel. Pay attention to the drain pipe must be temporarily blocked to avoid sundries falling into the drain pipe. After cleaning, scrape cement putty around the pit wall. Cement putty is also scraped around the reverse side of the floor drain to make it firmly combined with the ground. The center of the floor drain is opposite to the center of the drain pipe. Put it in the pit and press it hard. The level of floor drain should be slightly lower than the surface of ceramic tile. Wipe off excess cement and clean up the ground garbage. The most critical inner core is installed to deodorize, and the inner core can be taken out and cleaned at any time.

Second, the types of floor drains

(a) the traditional water seal floor drain:

The traditional water-sealed floor drain is bell-shaped, which is buckled on the sewer pipe mouth like a buckle bowl structure to form a U-shaped trap, and the sealing effect is achieved by using the "water seal" in the trap. Advantages of traditional water-sealed floor drain: low price, simple structure principle of water seal. The biggest advantage of water-sealed floor drain is that it can ensure deodorization effect as long as there is water storage. Water seal relies on water to seal off odor, which is relatively safe.

Disadvantages of traditional water-sealed floor drain:

1. The slow drainage speed is a major drawback of the traditional water-sealed floor drain, especially for the deep-water water water-sealed floor drain, the drainage speed will be affected to some extent. The floor drain with this structure can only be drained through two narrow circular gaps at turn 180, which is prone to poor drainage. When the displacement is large (such as washing machine and bathing drainage), temporary water accumulation may occur.

2. The structure of the traditional floor drain is unreasonable, and the water in the water seal is easy to dry up and be easily damaged by the negative pressure formed in the drainage pipeline system. The water seal of floor drain must keep water. Once the water in the water seal dries up, it will lead to the failure of deodorization function and make the odor in the drainage pipeline return to the room. General shallow water sealing floor drain has poor water sealing ability. If it is not used for a long time, or the indoor temperature is high after heating in cold weather, the water in the floor drain will evaporate. If you want to prevent odor, you must always add water in time to prevent the water from drying up and destroying the deodorization effect. The traditional deep-water sealed floor drain only lasts a few days longer than shallow-water sealed floor drain, but the deepening of water seal will make the deposition of dirt in water seal more serious.

The above is the tutorial sharing of replacing the floor drain yourself. The replacement method of floor drain is very simple and easy to install. You can look at the specifications of the floor drain at home first. We need to measure first, and then buy the same floor drain. The floor drain is divided into sizes, and the size of the floor drain is divided according to the sewer mouth. When we install the floor drain, we need to pry the original floor drain open. After the floor drain is pried open, we need to buy some glass glue to stick the edge of the floor drain.
