Because the basement is designed with toilets supporting children's playroom and gym, a sewage riser is needed to solve the drainage problem. The sewage pit and submersible sewage pump given by the developer at home are too ugly and poorly sealed. The sewage discharged from the bathroom will not be too smelly, which is simply unimaginable.

Therefore, the sewage riser has become a better choice for drainage in our basement, and there is no need to dig a hole, because the sewage riser has its own box, and it is an integrated injection box, which is not welded, so there will be no cracks and other loopholes, and there will be no diffusion of odor.

The sewage riser is installed behind the toilet or under the sink of the sink, which can hide the small machine well and will not affect the appearance. If possible, it can be installed under the hand washing cabinet or in a special equipment room, which does not take up space, or it can be installed by sinking, such as the sewage pit reserved by the developer. Moisture-proof measures should be taken in the pit to avoid water accumulation in the basement.

This kind of accumulated water outside the machine can't be discharged from the sewage riser. The machine drains the water from the water tank. If the water outside the machine doesn't want to be treated with a rag every time, either the pit is waterproof or an auxiliary pump is installed to drain the accumulated water in the pit. Even if it takes a long time, don't worry that there is no way to drain the accumulated water.
