The problem of blockages in the sewer system is familiar to many. In some houses, it is poorly designed initially, worn out over time, and sometimes people themselves forget about the basic rules of using the toilet, dropping there a variety of garbage, household waste. In order not to interfere with the flooding and exit of the faeces outside, today it is proposed to install shredding pumps, which are also called sewage or sewage pumps. Let's talk about them in more detail.

Chopper for toilet in the bathroom

Purpose

The chopper pump is a box with a pump inside. It is mounted behind the drain cistern and is often covered with plasterboard or lining to hide from the eyes. This allows you not to disturb the aesthetics of the room. To operate the device requires a connection to the toilet and an electrical outlet.

The scheme of the device is as follows:

  1. The stock enters the box of the chopper, where thick fractions are retained and the water goes on;
  2. When a certain volume is accumulated, the motor starting the shredder blades automatically turns on;
  3. The knife grinds solid waste and, under pressure, drains into the pipes of the sewage system;
  4. The treated waste is discharged through the branch pipes. Usually their diameter is about 45 mm.

Pros

Among the main advantages of such devices are:

  • Efficiently allocates all waste, prevents the formation of blockages;
  • The box itself has an attractive design, which often makes it an important element of the interior;
  • The price today is quite attractive, does not require large expenses for acquisition and installation;
  • Minimally consumes water, therefore it is not worth to be afraid of a sharp jump in utility bills;
  • With a competent installation does not violate the design of the room, because it hides behind the skin;

Cons

Together with the positive sides, the shredders are characterized by certain drawbacks:

  • Older devices emit a lot of noise that some can annoy. Although modern devaysy have no such drawback;
  • Price availability does not say that the chopper is worth a penny. So you have to invest a certain amount, and also spend money on doing the casing to close the box;
  • If you purchased a shredder of questionable production, you should not count on a long and trouble-free operation. Trust only trusted firms;
  • The device consumes electricity. Slightly, but it will have a little impact on your budget.

Specifications

When choosing a fecal shredder for a toilet, it is necessary to take into account the main characteristics. This will find the best option specifically for your toilet:

  1. Waste delivery range. The pump output is selected based on the distance of the gravity pipe from your toilet bowl. The standard device transports the runoff 100 meters horizontally and 10 meters vertically. As practice shows, such indicators are sufficient.
  2. Several devices are connected to the pump if necessary - a sink, a bathtub, a bidet. Think about whether you need it. Some buy individual shredders for each plumbing. This is an unreasonable waste of money. The combined pump perfectly copes with all devices alone. But if there are really many devices, then two pumps will be needed - for cold fecal runoff and hot clean drains( sink, bath, bidet).
  3. Temperature of transported liquids. Usually it is 40-90 degrees Celsius. If you connect the pump only to the toilet, the lowest temperature values ​​are enough. Shredders for the cabins, bathroom, shower will require a chopper with a 90-degree indicator. Otherwise the device under cold drains can not withstand such heating and will fail.

Types of

The variety of sewage pump-shredders is determined not only by technical characteristics, but also by the depth of installation. Allocate:

  • Submersible. Functionality at them wide as not only take away water from a toilet bowl, but also pump out water at floodings, showers. Some use them for watering the garden. The body is created taking into account its location in an aggressive environment, therefore the main elements are made of cast iron and stainless steel.
  • Semi-submersible. They are immersed inside the container, which must be cleaned. It is necessary to observe an important rule when installing - the pump component of the structure must be in the waste water, and the motor - on the surface. Semi-submersible pumps have a pipe diameter of up to 15 mm, and there are also restrictions on the size of the solids to be recycled.
  • Superficial. They are mounted at the edge of the reservoir with drains, and the submerged hose picks out the waste. These are compact, easy-to-move pumps that are easily mounted from place to place.

Also, pumps are classified based on water temperature and the presence or presence of a chopper in the structure.

For cold drains

there are two classes:

  1. Without a chopper. Several plumbing fixtures can be connected to them, the drainage temperature of which does not exceed 40 degrees. But you need to carefully monitor which wastes fall into the system.
  2. With chopper. Mount behind the toilet. When a certain amount of waste is accumulated, the shredder is turned on and chopped, then taken to the sewer.

For hot run-offs

There are also two classes:

  1. Without an adder. Perform several tasks at the same time - connect to a washing machine, dishwasher, drain the bathroom and wash basin.
  2. With chopper. Easily recycle waste, the temperature of which is 90-95 degrees, as well as the cutting of solid components.

Selection Criteria

To properly select a pump-chopper, answer a few questions:

  1. What system performance is required? This is affected by the amount of daily drains in your home.
  2. What is the size of the sewage pipe? Not all pumps are suitable for this or that type of sewage. Adapters may be required.
  3. What kind of waste will be dropped into the toilet, bathtub, other plug-in devices and what are their sizes?
  4. What is the distance from your toilet bowl to the sewage drain?
  5. Is it necessary to connect additional equipment, except for the toilet?
  6. What is the temperature of the treated waste?

Available sizes and compact models

Today, standard size pumps are available for shredders, which can easily be placed inside your toilet.

However, large devices are not always right, if the bathroom is small or there is not enough space behind the drain tank. The proceeds come compact models. The width of the box in such choppers is approximately 12 centimeters. Finding such a space behind the toilet is not difficult, nor will it be necessary to create complex and massive constructions of plasterboard to hide the box.

Carefully study the range in the market, determine the desired dimensions of the chopper. Find the right option today is not a problem.

Calculation of the minimum power

We have already said that the distance from the toilet to the sewer plays an important role in choosing the power. But how to calculate the power correctly, so that the device can cope with the task assigned to it?

The instructions and the passport of the device show all its technical characteristics. However, errors in the selection are allowed often. Do not rush to address to experts, as they take expensive for their services, but in fact you can figure out the nuances of power yourself.

So, let's imagine that the pump you selected transports waste at 80 meters horizontally and 7 meters vertically. Do not think that this is how it will really be.

First of all, the passport specifies the maximum performance. To realize such a transportation distance, it is necessary to turn on the pump for maximum power. This will lead to its rapid deterioration. Buy a chopper with a power reserve.

Another important point - the range and transport altitude indicators are mutually exclusive. Here, rely on a simple calculation formula - for each meter of waste transportation up the delivery range horizontally decreases by 10 meters.

For example, the pump capacity is calculated for 100 meters horizontally. But if the waste will have to be lifted by 1 meter vertically, then the first indicator is reduced to 90 meters.

Installation

The principle of installation of the pump-shredder is based on the execution of several fairly simple sequential operations:

  1. Pull out the lead pipe at an incline, using a tee to connect it to the system.
  2. To it connect the outlet for the pump, and it to drain, using a flexible design.
  3. Make sure that the corrugated tubes do not sag, the curvature is missing completely. Otherwise, the pump will have an additional load.
  4. Waste will enter the pump box by gravity, therefore it is important to follow certain rules:
  5. The hole of the pump inlet is placed above the outlet from the toilet bowl;
  6. The angle of turns is minimal, but better without it.
  7. It remains to connect the device to the mains and the installation can be considered complete.
