Pump for sink and other plumbing - purpose and features

There are a number of requirements for the installation of sewage and sanitary appliances, which often limits the layout of the house. In particular, plumbing should be located near the riser, and the bends should be installed under a certain bias. However, to solve this problem will allow the pump for the toilet and the sink, which this article is devoted to.

General information

A sewage pump is a small device that provides for the forced transportation of sewage through a pipeline within a house or apartment. Depending on the destination, the device is installed under the sink or near other plumbing.

Installation of the pump allows you to solve a number of problems associated with the organization of the sewer system. It is especially necessary in cases where it is difficult to ensure the effective operation of the system by gravity.

Merits

Among the advantages of a pump system are:

• Devices crush all organic inclusions which are available as a part of drains. Homogeneous mass is easily transported even through pipes of small diameter, thus blocking the occurrence of blockages is excluded (concerns devices for a toilet bowl).
• Allow to place kitchen appliances in rooms that are below the sewer line. Thanks to this, it is possible to organize a kitchen even in the basement or basement.
• They allow to install plumbing equipment at a great distance from the riser, when it is impossible to withstand the necessary wiring slope.

For these reasons, home and apartment owners are increasingly setting up a sewage system using a sewage pump.

disadvantages

As for the disadvantages of using this device, among them are:

• It is impossible to use the sink or other plumbing in the event of a power outage.
• About once a year, the pump must be cleaned, as it becomes clogged with grease, begins to produce an unpleasant odor, moreover, its throughput decreases (refers to kitchen appliances).
• The cost of using sewage increases.

Thus, if there is no urgent need, then it does not make sense to use a pump to drain water from the sink.

Types of pumps

All sewage pumps, which are used for domestic needs, differ in their purpose:

• For toilet bowl;
• For kitchen.

Below we take a closer look at the features of both types of aggregates.

Kitchen appliances

Pumps for the kitchen come in two types:

The pump under the sink in the kitchen is also called sanitary because it is capable of pumping contaminated water, but it does not have a grinder. Accordingly, drains should not have foreign objects.

A distinctive feature of such devices is that they have several inlets, so that in addition to the sink itself, you can additionally connect a drain from the shower or bath, as well as household appliances.

Most often they are installed under the sink in the closet, however, if desired, can be placed in another place. A feature of such devices, as already mentioned above, is the need for periodic cleaning.

Among the kitchen appliances, the following models have recommended themselves well:

• Sololift2 D-2;
• Grundfos Sololift2 C-3;
• SFA SaniVite Silence et al.

The cost of these devices ranges from 350 to 400 dollars.

Toilet Pumps

Devices of this type are designed exclusively for work with drains from the toilet bowl. They are installed on the floor behind the toilet at a distance of no more than 40 cm.

Outwardly, such a device resembles a plastic box the size of a drain tank. The unit is connected to the outlet of the toilet and electricity. When draining drains fill the pump, where the fecal matter and toilet paper grind the blades, after which the liquid under pressure is sent to the sewer.

Tip! The color of the cabinet can be chosen such that it matches the color of the toilet bowl. In this case, the device will not be evident.

As a rule, such devices can forcibly pump drains up to a height of 10 meters and in a horizontal plane per 100 meters. After pumping the liquid from the pump to the standpipe, the water trap of the toilet bowl is refilled with water.

Among the advantages of these units are:

• Provide the ability to use the discharge pipe from the pump with a diameter of 18-40 mm. Thanks to this, the pipeline can be hidden behind gypsum plating or, for example, under the ceiling.
• The toilet can be installed in any room, regardless of the location of the riser.

The highest quality devices are from the French manufacturer Grundfos. Depending on the model, the price for them ranges from 350 to 450 US dollars.

Note! The maximum temperature of the drains that such a pump is capable of pumping is +35 - +50 degrees Celsius. Therefore, it is impossible to pour boiling water into the toilet.

I must say that recently pumps have appeared on the market for suspended toilet bowls. They have a more compact size that allows you to hide them in the installation. The thickness of such devices does not exceed 12 centimeters.

Also there are models of toilet bowls which have the built-in pump. This option is the most convenient, however, the cost of such plumbing is very high.

Installation Features

Below, as an example, consider how to install a sewage pump in the kitchen. First of all, it should be said that the device should be selected depending on the number of appliances that consume water, which I can work at the same time. The more of them, the greater should be the capacity of the pump.

As mentioned above, the device can be positioned anywhere, the main thing is to plan the position of the unit so that all supply pipes are installed with a slope of 3 centimeters per meter, besides they do not have a large extension.

By itself, the connection instruction is extremely simple:

• First of all, insert the supply pipes into the inlets. Connections of pipes with incoming connections are the same as for plumbing fixtures.
• Next, you need to install the pump and attach it to the floor or wall with screws or other fasteners. On the case of the device for these purposes there are special cast ears.
• After that, a drainage pipe is connected to the outlet.

At this installation is completed, as we see, nothing complicated about it.

The only thing before you start to work with your own hands, you should familiarize yourself with some of the rules that are listed below:

• If the system uses two or more pumps, then for each of them it is necessary to make an individual entrance to the main or common riser. Combining the discharge pipes of pumps into one is prohibited.
• If the discharge pipe from the pump has a long section in the horizontal plane below the level of the pump, then it is necessary to install a 0.7 bar valve at the highest point, which will provide air access after turning off the device.
• Some models require the arrangement of the air cooling system of the electrical circuit. In this case, complete with the device, there is a plastic pipe that needs to be connected to the body and brought vertically 50-70 cm higher than the unit itself. In this way, fresh air is supplied to the hot circuitry for cooling.
• The discharge pipe must be made of hard plastic, for example, polyethylene or polypropylene. Flexible corrugation in pressure sewer systems can not be used.

Here, in fact, all the main features of the kitchen pump connection. It should be noted that the process of installing the toilet device is not fundamentally different from that described.

Conclusion

Installing a sewage pump for a sink or toilet bowl greatly simplifies the design of the sewer system. However, at the same time makes it volatile. Therefore, the use of this device is advisable only if necessary.
