Sewage system without faults
To ensure that the sewage system does not cause any malfunction, it is necessary to observe the only condition: to ensure a permanent, albeit slight slope, of the pipes towards the location of the waste water outlet. It is also necessary to avoid turning the pipes 90 degrees, because such turns will contribute to quick clogging and difficulties in cleaning activities.
In addition, you need to have always at hand a pump, necessary for pumping sewerage. Correctly selected equipment will help to get rid of many problems associated with the pollution of sewage.
Which pumps are used to drain the sewer?
There are two types of pumps for pumping out the water, which depend on their contamination:
- fecal;
- drainage.
These two systems are often confused, however, there is a difference in their functions and design features. Drainage pumps will be needed when it is necessary to pump liquid from a dishwasher or washing machine that has fallen into the basement or settler. This equipment is ideal for pumping liquids with a minimum amount of small solids.
The peculiarity of the fecal pump in the presence of enlarged channels, through which solid particles can pass, reaching a size of at times 80 mm. There are improved models of fecal pumps, which are equipped with a device that helps to grind household waste. By means of an impeller equipped with a cutting edge or with a knife, such a pump will cope with sufficiently solid waste.
Let's consider in more detail the main types of pumps for pumping out feces.
Types of fecal pumps
There are four groups of devices, the purpose of which is to drain the sewer. This classification is based on the presence or absence of a mechanism for grinding, the temperature of the water for pumping, the method of installation.
The first type of pump without a chopper is suitable for pumping cold water. This type of equipment is considered one of the cheapest devices in this category. Its purpose is to pump out pure water or a pool of liquid. For proper operation of this device, the temperature of the drains is important - not more than 40 degrees.
The second type of pump, which does not have a chopper in its structure, is suitable for pumping hot runoff. That is, this device can cope with the evacuation of contaminated liquid, heated up to 90 degrees. This equipment is often used in baths and saunas.
A pump equipped with a chopper and designed for pumping cold sinks is the most common type of equipment. Its main feature is that it can easily cope with the consistency of the toilet. He is able to jam the hygiene products, hair, feces that have got into the water and to pump it all out with dirty waters. This pump will show quality work, if you adhere to its temperature characteristics - the temperature of the liquid should not be more than 40 degrees.
The second type of pump equipped with a chopper is used to remove hot runoff. Its ability to raise sewage with a temperature of 90 degrees, allows it to be used for baths equipped with a toilet. This device can save the owner of the bath from clogging the sewage system.
Selecting a pump for sewerage
When choosing a pump, you should pay attention to the following quality indicators: material, power, cooling method, maximum head.
So, the stuff. It is necessary to take into account its anti-corrosion properties, because the pump will work in an aggressive environment. Completely suitable devices are made of stainless steel, plastic or cast iron.
The capacity of the device will directly depend on the performance of the equipment. However, not necessarily a powerful aggregate will show performance. Household pumps can pump 5 cu.water, this is enough. There is also such equipment, which during this same period of time can pump out five times more liquid. Therefore, when choosing the power of the device, it is necessary to take into account the volume of the pit for which it will be applied.
Typically, the pump head is standard - 10 m, that is, the machine can lift liquids to a height of 10 meters. Many manufacturers practice the manufacture of pumps with less pressure.
With regard to such a parameter as the cooling method, it is advisable to choose those models whose cooling system is based on oil. Such equipment is more reliable due to the efficiency of this cooling method.
