If you want to do secondary drainage in the bathroom, should you dig it again?

There are a lot of pipes in this area of the toilet and water must be used every day. Especially when you take a bath, there will be a lot of water left on the floor and walls. Therefore, when we renovate the toilet, we must do waterproofing work.

When decorating the bathroom, it is usually necessary to carry out the secondary drainage work of the bathroom to ensure the normal use of the bathroom. For the secondary drainage in the bathroom, many people are not very clear, in fact, the practice is simple, that is, the ground installation of the ground is a drainage, and the floor installation leakage is called secondary drainage.

If your home is a sinking toilet, there is no secondary drainage, the water in the caisson is full, and it cannot be discharged, then: 1. The water level is full, and the pressure at the bottom of the caisson is gradually increasing, and the bottom that has no water leakage may be soaked downstairs. 2. There is no water leakage at the bottom of the box, but as the water level rises, it slowly penetrates into the ground and walls over the threshold of the toilet.

The tiles on the walls may peel off, the walls may become moldy, the walls have paint, and the wooden floors outside the toilet may rot.

The method of secondary drainage of the bathroom: build a special drainage outlet for the sand and ash layer. When the waterproof layer is found to be sloped, the seat of the special drainage outlet is at the lowest point, and the position of the drainage outlet should pay attention to the waterproof repair.

After the waterproofing is over, pay attention to protect the drainage outlet from being blocked by sediment when laying the floor tiles, and drain the water if there is a gap.

2 .There is no need to make a separate drain. When the waterproofing layer looks for a slope, simply use the existing drain to drain the water.

Generally, the location of the drain pipe is the leakage location. Once determined, this position will reach its lowest point. Make "stagnant water" at the root of this pipe, and make a small hole in the exhaust pipe at the bottom for drainage.

It will also not affect tile stickers and floor leakage.

Currently, very few construction workers do this. The workers all felt that it was a small problem. If only it could be waterproof.

However, if you have a problem with the floor of your home toilet not drying easily, and the wall next to it is damp again, you must first consider whether the water pipe is leaking. Second, it's the cause of the dust and water accumulation.

The principle of secondary drainage is to sneak into the bottom of the toilet and cause an invisible leak. In the case of backfill layer water, the water can be completely drained out of the drain through this invisible leakage, but since this secondary drainage is mainly aimed at sunken toilets, if the house is a sunken toilet, don't forget to make a secondary drainage. The construction of secondary drainage is not complicated, and almost all renovation workers can carry out engineering work.

Yes, because the second sewage discharge will have to be re-selected, because the second sewage will be needed after the place is blocked.

It is necessary to dig again, because the secondary drainage is very important at this time, and there is no way to do it well if it is not dug up.
