How to choose a pump for the toilet
Often, redevelopment and overhaul of old buildings can give owners a large number of unpleasant surprises. Most often, the rosy picture is violated by unsuccessfully located engineering networks. One of the most common problems is the impossibility of transferring a bathroom to another room or new equipment. This is due to the sewage system of a private house, which is usually self-flowing, but a sewage pump for the toilet can help solve this problem.
In this case, the gravity flow system becomes partly pressurized. Then, even if the toilet is installed below the central collector, it will function normally. Below we will describe in more detail about this device, you will learn about the principle of its operation, how to choose its power, as well as to carry out the installation of this equipment.
We understand the equipment
- In appearance, the pump resembles a small plastic box placed behind the shelf of the toilet bowl.
- The device does not spoil the aesthetics of the bathroom and it looks like an additional drain tank.
Tip: if the need arises, the equipment can be removed in a box of plastic panels or drywall.
- Standard models of such pumps are designed to transport fecal masses horizontally up to 100m, vertically up to 10m. Although there are more powerful devices.
Main characteristics
When choosing equipment for the forced movement of stocks, we recommend turning to the following features of the devices:
| Transportation distance | This parameter affects the power of the pump. The farther the gravity sewer pipe passes from the bathroom, the more it should be. The usual ability to transport wastewater is approximately 100 m horizontally and up to 10 m vertically, which in most cases is sufficient. |
| Optional equipment | When in the bathroom there is not only a toilet, but also a washbasin and a shower cabin, it is not necessary to install a separate pump for each element of the system. We recommend to buy a combination device. |
| Recommended fluid temperature | This parameter is in the range of 40-90? С for various equipment options:

Tip: when installing a forced sewage system for a bathroom in which a large number of household appliances and plumbing equipment are installed, we recommend separating cold fecal drains and clean hot water by buying a separate pump for each line.
If a suspended toilet is installed
In a small room, if you want to save space as much as possible, often hanging toilet models are placed. For such plumbing equipment, specially designed devices are offered, whose tank width is approximately 120 mm. You can simply disguise it in a drywall box, which also installs a frame for fixing a toilet bowl and a cistern.
Relatively recently, toilets began to be sold in retail chains, which are equipped with a built-in grinder. This device is also designed to connect to it additional plumbing equipment. This type of toilet does not have a flush cistern.
When the drain key is pressed, access to the water from the water pipe is opened and at the same time the grinder is turned on. A mandatory requirement for the installation of this equipment - the pressure in the water supply network must be at least 1.7 bar.
Calculation of the required power
We want to warn you that even if the instruction clearly describes all the main characteristics of the equipment, it is quite easy to make a mistake with the choice. It is not always possible to find a good specialist in this profile, so we will understand this issue on our own.
The most common mistake - the wrong choice of power devices. For example, if the instruction states that the pump can pump liquid horizontally at 80 m, and vertically at 7 m, this does not mean that everything will be so.
Why?
Let's understand:
- In the instruction manual usually indicate the extreme parameters. The situation data for the pump are peak, so any unrecorded load will immediately lead to a malfunction.
Tip: when selecting equipment, always leave 15% or more for power reserve.
- Characteristics presented in the instructions can be called mutually exclusive.. This is due to the fact that when transporting a liquid only in a horizontal plane, the pump can push it up to a maximum of 80 m, but when it is necessary to raise it by 2-3 m, the feed distance will decrease significantly. We suggest you use this calculation formula - for each meter of ascent, the transportation distance horizontally decreases by 10 m.
Installation Features
Do not worry, even if you have never worked with such equipment, you can easily connect it to the toilet with your own hands. When installing the pipeline from the pump to the sewer, you need to know only two parameters - the height and the length of the lift.
They must comply with the characteristics of the shredder. The remaining data related to the angle of elevation, the materials used and the configuration of the line can be any.
Tip: try to avoid sharp angles of rotation of the pipeline, so as not to create an additional load on the equipment.
Conclusion
The above-considered device - a sewage pump for a toilet bowl and a sink is an indispensable equipment in the case when you want to place a bathroom below the level of a central sewer. Thanks to its power, all hot and cold drains will be quickly delivered to their destination.
The equipment is not difficult to connect, so it is quite possible to cope with this task on their own. The video in this article will provide an opportunity to find additional information on the above topic.
