Installation of a sewage pump with a shredder

The submersible sewage pump with a chopper is also known as a fecal pump. Such equipment allows automatic processing of sufficiently coarse solid wastewater particles, which significantly reduces the possibility of clogging of sewerage.

The device and the principle of functioning

Sewage pumps for the house - mechanisms, the operation of which contributes to the formation of an excessive level of pressure in the system. This, in turn, allows you to perform a forced diversion of sewage.

As soon as the sewage passes through the permissible limits, the submersible sewage pump with the chopper pumps them out while simultaneously crushing the solid particles. As a result, impurities are converted into a liquid homogeneous mass.

Since such systems are inevitably in contact with moisture due to the duty of service, installation of a sewage pump made of materials capable of resisting corrosion is recommended.

As for the distinctive design features of the aggregates of this plan, here it is worth noting the presence of wide flow channels, which provide greater throughput when passing through the impurities of the coarse fraction. The decisive role here is played by the shredder, which helps prevent clogging of the system.

Design features

In appearance, such units resemble an ordinary plastic box, the dimensions of which do not exceed the dimensions of the standard tank. When discharging the discharge, impurities enter the pump casing, where they are processed by metal blades. Under pressure, the formed homogeneous mass is directed to the drain riser. Such units contain a valve that blocks the access of waste sewage back to the body.

Where better to put a sewer pump? Installation in a barrel in the room, on the floor, in a specially prepared niche in the wall - these are just a few options for mounting such units. At the same time, the location of the sewer pipe does not play a decisive role when choosing the location for the pumping equipment.

The most powerful, functional models are capable of raising processed sewage by pipe connections in the vertical direction by 10 m, and horizontally by more than 100 m.

Types

Household sewage pumps with a shredder are conventionally divided into separate categories:

• Semi-submersible and submersible.
• Outdoor for working hot wastewater.
• Outdoor for working with cold water.

Installation of sewage pump submersible and semi-submerged type allows to efficiently pump clean water and sewage with small particles with temperature up to +40 ^о С.

Equipment for working with cold wastewater is used to drain liquids from toilet bowls, sinks, septic tanks and shower cabins. Such models are presented in the form of the most compact tanks. The presence of reliable knives allows you to easily process heavy waste. A productive engine makes it possible to quickly direct the sewage to the sewer pipe.

Household sewage pumps for working with hot sewage are also equipped with powerful knives that easily process materials of a relatively small fraction when they enter the toilet or sink.

Materials of manufacture

For the production of functional elements that come into contact with the liquid during operation, the following applies:

1. Polymers are quite strong bases, which make it possible to reduce the total cost of aggregates.
2. Stainless steel - provides a special durability of the equipment.
3. Cast iron - has the highest strength and reliable resistance to mechanical stress. The disadvantage of such structures is considered to be an impressive weight, which can make it difficult to install under certain conditions.

Pump sewer with chopper - installation

Before proceeding with the installation of the equipment, it is necessary to pay attention to the diameter of the inlet pipe of the pump, which must correspond to the parameters of the sewer pipe that comes out of the toilet bowl. If the sizes do not match, it may be difficult to create a sealed connection.

Installation of the sewer pump by one's own hands is carried out in the following sequence:

1. The supply pipes are connected to all inlet connections of the unit. At the same time, a slope of 3 cm is observed for 1 m of length.
2. The pump is mounted on the floor behind the toilet bowl, placed in a static-installed container or built into a specially prepared opening in the wall. The design is fastened with fasteners, set on plastic dowels.
3. From the drain pipe to the pump, a sewage pipe is laid. If the existing operating conditions require the installation of several interconnected pipes, joints must be glued, welded or soldered to avoid leakage.
4. If there is a need for vertical drainage of the sewer pipe, its flapping from the inlet of the pump upwards is no more than 30 cm. Only in this case it can be expected to maintain a stable pressure in the system sufficient for efficient operation of the unit.
5. A slope of the drain pipe is created, which ensures draining of impurities by gravity.
6. Element for processing solid sewage is connected to the power supply.
7. Pump sewer with a shredder, the installation of which is completed, is checked for efficiency. All joints and joints are inspected for leaks.

Installation of sewage pump in the well

Separate modifications of aggregates with a shredder have been successfully used not only to reduce the likelihood of blockages in the sewer, but can also be used as an effective means for cleaning pots for drinking water.

Installation of sewage pump in the well is performed as follows. To begin with, the discharge nozzle of the unit is connected to a pipe that will be used for pumping water. Cope with the task can be using a yoke, the fastening of which is clamped with a screwdriver or pliers.

Sewage pumps of a dry installation contain a check valve that needs to be checked for operability. The latter allows avoiding the return of water to the reservoir during the pumping process.

Installation and fixing of the drainage unit are made on a flat, solid surface. The pressure hose is placed vertically in the pit. If necessary, it should be fixed on the walls of the tank, because the water pressure may be quite strong.

In conclusion, it is enough to immerse the end of the pipe to pump the liquid to the bottom of the well and connect the grinding unit to the power grid. To prevent damage to the pump due to clogging with silt and large particles, it is recommended to purchase a special float, which will serve as a guide for determining the water level.

Features of operation

Pumping equipment with a mechanism for grinding uncleanness excellently copes with the processing of personal hygiene products, fecal masses. However, some relatively low-power units are not able to utilize the truly solid waste. Therefore, in order to avoid a quick failure, it is worth keeping an eye on the nature of the sewage that is being processed by such equipment.

Devices that are installed in the kitchen and serve for grinding waste that enter sewage through the sink, daily work with greasy sewage. To prolong the life of the pump, which is used in such conditions, it is recommended that it be cleaned regularly. If this requirement is not complied with, the inside of the unit will be covered with an abundance of fatty deposits, and they will not only exhale a stench, but ultimately lead to equipment breakdown.

How to prevent a malfunction?

If the operating rules specified in the technical documentation are not observed, the sewage pump with a shredder quickly becomes unusable. Most breakages are the result of frequent start-up of the unit "dry" or the result of clogging of the system with solid particles of coarse fraction.

To increase the service life, it is enough to take care of the installation of automatic protection of cutting elements and the engine of the unit. This is especially important when using a pump in a country house, where there is an increased probability of sewage of branches and stones. In the absence of such protection, it will be much more necessary to repair and maintain equipment.

Benefits

The installation of a sewage pump with a shredder facilitates the processing of relatively solid waste that is part of the sewage. As a result, the patency of the mass is increased through pipes of the smallest diameter.

Among other advantages of the equipment is the opportunity to connect to household appliances, which is located below the level of the sewage pipeline. Thanks to this, it is possible to ensure an effective drainage of sewage from a sink or toilet bowl installed in a basement. Moreover, the power of most pumps is sufficient to operate the plumbing equipment at a considerable distance from the riser.

disadvantages

Functional pumps with a shredder have some disadvantages:

• Operation of devices is not possible in the event of a power outage.
• There is a need for frequent cleaning of the units connected to the sink, due to clogging with fatty deposits.
• Increased costs for the arrangement of the sewage system.

Eventually

Sewage pump with grinding mechanism is a fairly simple, but at the same time highly efficient equipment. When choosing a unit for servicing the sewerage system of a private house, special attention should be paid to the power and productivity index.

Due to the correct installation, operation according to the requirements of technical documentation, timely repair and maintenance, sewage pumps for the house can serve for many years without the need to replace the main functional units and important details.
