Advantages and disadvantages of sunken toilet and solutions to water leakage

Submerged toilet means that when the main body is built, part or all of the structural layer of the toilet is sunk to a certain height (generally 40CM) away from the corresponding floor, so that the horizontal drainage pipe of the toilet is buried in it, and then backfilled with light materials, and only one hole needs to be left on the structural surface as a drainage riser. This paper will discuss the advantages and disadvantages of sunken toilets and the solutions to water leakage.

Convenient drainage device

Sinking toilet is convenient for the drainage layout of the bathroom, which works on this floor and does not involve the downstairs.

Reduce noise

Submerged toilets reduce toilet noise.

Flat top surface

The top surface of the sunken toilet is flat and there is no drain pipe.

Waterproof treatment is very troublesome

The waterproof treatment of sunken toilet is more troublesome and the decoration cost is higher.

There is a great hidden danger of water leakage.

There is a hidden danger of water leakage in the sunken toilet, and the maintenance is also more troublesome, because the gravel layer filled in the middle will gradually sink after a long time, cracks will appear in the cement layer and waterproof layer above, and water will leak down to the filling place. Because there is a waterproof layer below, water can't leak out, and the result is accumulated in the filling layer. After a long time, the whole filling layer is full of water. Eventually, with the extension of time, the waterproof tank below will also leak, and a large amount of accumulated water will gush out.

Waterproof solution

After the sinking ground is waterproof, the ground should be made into an inclined plane, and the sewer pipe should be the lowest. Then the sewer pipe should be opened next to the sinking ground, wrapped with stainless steel net, covered with pebbles to guide water, and then covered with sand. If the bathroom area is large, it is necessary to connect a flow pipe, and the following process is exactly the same. The advantage of this process is that even if leakage occurs, the water entering the sinking area will flow out of the sewer and will not be silted. This is the key.
