How to properly make a sewer in the basement

Installing a sewer system in your basement may seem like a difficult undertaking, but with the correct advice, it can be a rewarding and manageable project. In order to make sure everything works properly and to prevent problems down the road, proper sewer installation is essential whether you’re looking to add a bathroom, laundry room, or other utility space.

Firstly, preparation is essential. You can save time and money by being aware of the layout of your current plumbing system and the unique needs of your basement space. It is necessary to take into account the slope for appropriate drainage, the kind of pipes to utilize, and the location of the main sewer line connection.

Selecting the appropriate materials is crucial. PVC pipes are widely utilized because of their dependability and simplicity of installation. To stop leaks, it’s crucial to make sure all connections are tight and safe. You can obtain the essential rules and regulations to abide by by speaking with a professional or checking the local building codes.

Remember to get adequate ventilation. For the system to function effectively and to keep sewer gases out of your house, proper venting is required. If the venting for the new basement fixtures is insufficient in your current system, you may need to install a vent stack.

Lastly, consider maintenance in the future. You can avoid a great deal of trouble later on by keeping your sewer lines accessible for any necessary maintenance or blockages. Easy-to-reach pipe sections and cleanup ports will make system maintenance much simpler.

Building a suitable basement sewage system is necessary to keep your house tidy and operational. Make sure you have the right slope for drainage when you first plan the arrangement. Use dependable, high-grade fittings and pipes to avoid clogs and leaks. Before completing the basement, make sure all connections are tight and test the system. In order to prevent sewage backups, don’t forget to install a backflow preventer. You can install a dependable sewer system that keeps your basement dry and hygienic with careful planning and execution.

Types of waste

There are two categories of liquids released from the basement floor: heavily polluted and moderately polluted. In the first instance, the composition is devoid of both solid particles and suspensions. These liquids originate from the swimming pool, sauna, and washing machine.

The toilet’s wastewater is categorized as extremely polluted. They have fibers and solid inclusions in them. Pumps with a large throughput grinding function are required to raise them to the top. It is sufficient to incorporate a sololift or a conventional pump with an integrated storage tank into the plan in order to transport wastewater that is moderately contaminated to the main sewer pipe.

Wastewater is separated not only into categories such as moderately and heavily polluted, but also based on temperature, or To. Very hot liquids are beyond the reach of some equipment. Dishwashers and washing machines can provide them. After hygiene procedures, drains are typically not considered extremely hot because their temperature rarely rises above 45°C.

Lead options

A house’s basement sewage system typically serves multiple locations simultaneously. The issue of the combined or independent removal of waste liquids will need to be resolved. A comparative study of their volumes is done for this reason.

When the intended water consumption is less than 1 mⅾ per day, a sololift that has been properly chosen for performance will have no trouble expelling this amount of wastewater. Installing a tiny pumping station is an alternative.

Therefore, there is no need to separate the drains if the owner of a country house has no plans to install a bathtub, swimming pool, or bathhouse in the basement. When wastewater volume exceeds 1 m^, separation is necessary. In this instance, more intermediate storage tanks for "clean" wastewater are put in the outlet.

The fact that the storage tanks integrated into the pumps have a comparatively small volume helps to explain this solution. The machinery might not be able to complete the task if you forget to add more storage tanks. However, the pool’s water won’t need to be changed as frequently, negating the need to install a costly, high-powered fecal pumping system with grinders. It’s just not rational.

When the home’s sewage system is independent, all of these solutions make sense. Installing a high-power fecal pump suffices if it is linked to centralized networks. It will handle wastewater discharge into the discharge main.

Equipment for joint pumping of wastewater from the basement

A sololift is installed if calculations indicate that one branch will suffice for the forced pumping of wastewater. It is specialized machinery with the following structural components:

• pump;
• chopper;
• storage block.

Because the equipment is compact and small in size, it can only handle small amounts of wastewater.

The ideal choice for the restroom. Because of the design’s sloping bottom, sedimentation is prevented.

When the system is operating, an increase in wastewater flow rate creates a vortex draft that draws silt from the tank’s bottom. You must take into account the particular kinds of input connections that the sololift is intended for if you want it to last for a very long time.

The following plan governs how the sololift functions:

1. Waste liquid flows from the plumbing fixture into the sololift tank. Accumulating gradually, it partially settles here. Heavy inclusions settle to the bottom, light ones are retained by the filter.
2. When the container is filled to a critical level, the unit turns on, the pump comes into operation and begins pumping out sewage.
3. The chopper, located in the upper zone of the tank, crushes large elements. The resulting mass enters the pump, mixing with water. Next, the pump lifts the mixture up the pipes and it enters the external sewer system.
4. The wastewater level drops – the pump stops functioning. For large volumes of wastewater, it is more advisable to use a pumping station specifically designed for working with sewage liquids. According to the principle of operation, this is the same sololift, but the storage tank is larger and the pumping equipment is more powerful. The pumping station will solve the problem of transporting wastewater from all points in the basement.

Liquid can be lifted up to 9 meters vertically and moved up to 100 meters horizontally by the pump. The noise is nearly imperceptible because it is closed off on all sides.

A grinder that takes in both "clean" and "dirty" wastewater is a necessary component of the station. This impeller has jagged edges on it. Solid materials are ground into a homogenous mass by its rotating action, at which point they depart with the liquid.

The standard model’s body is composed of plastic that is simple to clean. Three outputs are available for connecting to various locations. The integrated level sensor allows the pump to operate automatically by turning it on and off. The carbon filters that are included guarantee low levels of odor.

A sewage pumping station’s ideal power range is 8–24 m⋍/h. The majority of contemporary models come with features that let you stop reverse flows. The space that is available should be taken into consideration when choosing the pumping station’s features and dimensions.

Equip a designated niche or install the equipment in the room where wastewater is extracted. Equipment is kept in a separate room, if there is enough room.

Reverse current and protection against it

There is a chance that the lower level pipes will fill with sewer due to the peculiarities in the basement sewer system’s placement in relation to the main pipeline. There are two ways to completely eliminate the risk of backflow: active protection and passive protection.

In the first instance, a pumping system with unique backflow-preventing devices must be installed. This feature is present in most recent models. For this reason, you should find out what extra features a pumping station has before making a purchase.

Installing storage tanks and valve modules in the discharge pipeline is the second option. The latter are situated on the nearby land. They serve to control the volume of wastewater that is released into the septic tank. One disadvantage of valve mechanisms is the frequent blockages and their removal.

Regarding the logic of a backflow prevention device, experts are divided. Some argue that this is a waste of money, but others offer proof that hygienic protection is necessary.

Maintaining a comfortable and functional home requires installing a suitable sewer system in your basement. It entails thorough planning, selecting appropriate materials, and abiding by regional building codes. You can avoid potential problems like leaks, blockages, and offensive odors by following these steps.

Start by figuring out how your basement is laid out and where your sewer lines should go. This involves planning the locations of fixtures such as sinks, showers, and toilets. To guarantee that waste flows freely and that odors are expelled outside, proper slope and venting are essential.

Make use of sturdy materials, such as PVC pipes, which are simple to install and corrosion-resistant. To stop leaks, make sure all connections are tight and sealed. Future maintenance and repairs will be simpler if cleanouts are strategically placed.

Before covering up your system, don’t forget to test it. Inspect all fixtures for leaks or sluggish drainage by running water through them. Resolve any issues right away to prevent bigger ones later on.

Last but not least, always abide by local building codes and laws. These rules are in place to guarantee the effectiveness and safety of your sewage system. If in doubt, seek assistance with the installation from a qualified plumber. You can have long-term dependability and peace of mind with a properly installed sewer system in your basement.
