Everyone knows that the principle of operation of the sewage system is to move effluents down the pipes, by gravity, due to the forces of gravity. Drains, according to the laws of physics, always rush to the lowest point, which is the entry point to the common sewer riser. If the toilet is located below this point, then the drains from the whole house will just collect in your pipe. They will not be included in the common stock. What to do if, for example, the bathroom is located in the basement or in the basement? The way out can be found quite simply by installing a fecal pump with a toilet chopper right behind the toilet. The new system will cease to be completely gravity flow, becoming partially pressure.
In appearance, the sewage chopper pump for the toilet looks like a compact plastic box, not exceeding the dimensions of the cistern. It is usually installed on the floor, just behind the toilet, but can be hidden in a wall or behind a plastic or drywall partition. It does not require maintenance, as it has a self-cleaning function. The drains from the toilet enter the pump housing, where they are crushed by metal blades and sent under pressure to the drain riser. There is a non-return valve in the body of the device that does not allow drains to return back to the tank.
Thus, the use of a fecal pump with a chopper for the toilet will allow you to equip a bathroom, sauna, laundry room or other utility room anywhere in the house, regardless of the location of the sewer riser. On average, such a pump can lift drains vertically up to 10 m, and pump them horizontally by 100 meters or more. Specific values depend on the device model and its characteristics.
How does a grinder pump work?
To install and connect this useful device, you need an electrical outlet with a mains connection. The sewage pump for the toilet bowl is switched on automatically, after flushing the water in the tank. When a certain water level in the device body is reached, the engine and pump start. Knives grind fecal matter, small waste and toilet paper. Under the action of the pressure created by the pump, the crushed waste, together with water, enters the drain pipe.
Types of pumps and features of their choice
Commercially available household sewer pump shredders differ from each other in several ways. Knowing these differences, you can choose for your home exactly the unit that suits you best.
Structurally, all models are divided into the following types:
When choosing a grinder pump, pay attention to the following pump parameters:
1. Ability to connect multiple plumbing fixtures. For example, in addition to the toilet bowl, you can bring the drain of the washbasin and shower stall to the pump. If you want to do this, then purchase a combined device that has several inputs.
Tip: If your bathroom is equipped with a large number of plumbing fixtures, it is recommended to install another pump, distributing the fixtures between them. One device will be responsible for the cold drain, and the other for hot water.
2. Temperature of the content being pumped. A toilet bowl faucet pump will perform best in the temperature environment for which it is designed. Some models are adapted to work with drains having temperatures up to 40 degrees. If you connect the device only to the toilet, then any kind of pump will work for you. Some models are designed specifically for pumping hot liquids. They are able to pass through themselves drains with temperatures up to 95 degrees. If you plan to connect a washing machine or dishwasher, shower or washbasin with hot water to such an appliance, then choose the appropriate model for hot water.
3. Pumping distance, that is, the distance from the pump to the sewer riser. Knowing this indicator, you can select the required power and pressure of the device as accurately as possible.
Tip: Please note that simultaneously pumping drains horizontally and lifting them to a height will significantly reduce the indicated values. When the drains rise up by 1 m, the horizontal range is automatically reduced by 10 m. When choosing, consider both of these parameters, choosing power with a small margin.
The relationship between the change in the pressure of the fecal pump vertically and horizontally, which must be taken into account when installing Installation
Before installing the pump in a permanent place, pay attention to the diameter of its inlet pipe. It must match the diameter of the sewer pipe coming out of the toilet. If they do not match, you will not be able to make a tight connection.
The floor sewer pump with a grinder, which is installed independently, is mounted in the following sequence:
- supply pipes are inserted into all inlet pipes of the pump (with a slope of 3 centimeters per 1 meter of length) or plugs;
- the pump is installed in a permanent place behind the toilet and is attached to the floor with a puncher and dowels;
- a sewer pipe is laid from the pump to the drain riser. If several pipes are joined together, then the connections between them must be welded, soldered or glued. If it is necessary to vertically withdraw the pipe from the pump, the pipe must be turned up no further than 30 cm from the pump outlet. In this case, normal pressure will remain in the pipe;
- the drain pipe leaving the toilet is connected to the pump using a corrugated pipe. This takes into account some features: the entrance to the pump housing must be located below the level of the outlet of the pipe from the toilet. It is also necessary to slope the drain pipe to ensure the movement of drains by gravity;
- the toilet grinder pump is connected to the mains;
- the operation of the unit is checked and the absence of leaks in the joints of the elements of the system.
Tip: During installation, do not allow the drain pipe to turn at significant angles, as this places additional stress on the pump components.
