How to prevent sewage backflow in the basement?

Whether it is basement drainage or same-floor drainage, as long as there is no sewer pipe, we will need the sewage lifting pump this electrical product to solve the problem of drainage, this is this kind of drainage equipment into the country, for our traditional one pit two pumps of the first drainage change, but with the passage of time, this drainage method due to the continuous diversification of our needs, it gradually can not meet our diverse drainage needs, machine drainage noise, It is impossible to achieve mobile phone control with the whole house intelligent linkage, and once the machine runs continuously, there is a problem.

This kind of reason has promoted the sewage lifter to make its own changes, think more new directions, intelligent development is a big development direction, on this basis, continue to deepen the function adjustment of the sewage lifter.

So what kind of drainage can the intelligent sewage lifting pump do?

The intelligent sewage lifting pump can be remotely controlled by mobile phone through the Internet, in addition to the start and stop can be controlled, the start and stop liquid level can also be adjusted, and the real-time water level in the water tank can be viewed on the mobile phone at any time to understand the operation of the machine.

Its operating principle is the same as the traditional sewage lifting pump, after the water level rises to the starting level, the machine automatically starts drainage, and the water level will stop working when it drops to the stop level, but the use and structure of the motor have been upgraded, using the S1 electric motor formula, so that the machine can operate continuously, even if it starts frequently, there will be no problem, plus the use of oil-cooled motor, so that the mineral oil fills the entire inside of the motor, and can absorb noise while cooling the motor, so that the machine can run silently.

Then the intelligent sewage lifting pump can let the machine clean itself, reduce the manual maintenance cost of the machine, can be connected to the tap water pipe at ordinary times, form a 360° high-pressure water column to flush the inside of the water tank at start, set the number and time of the self-cleaning system on the mobile phone, and regular self-maintenance makes the service life of the machine longer and the experience better.

1. It is necessary to set up a septic tank outside the basement bathroom, the septic tank should be lower than the bathroom, and then calculate how big the intelligent sewage pump is set according to the displacement, and pump the sewage to the outdoor sewage well.

2. It is necessary to set up a sump in the basement, and then install a sewage pump with a diameter of 50mm to pump the sewage to the outdoor sewage inspection well, and to prevent rainwater from backfilling, a shut-off valve can be installed on the pipeline!!

In order to prevent backfilling, the basement of high-end residential buildings is equipped with sewage lifting pumps. It can be effectively prevented.

1. The brand of sewage lifting pump is different, and the price is different. Tens of thousands of yuan and more than 100,000 yuan.

2. Now the basement of the villa is generally used as an entertainment room or chess and card room, and it is no longer synonymous with a utility room. Therefore, it is necessary to prevent sewage from backfilling.

The building code requires that the kitchen and bathroom should use separate sewer pipes, and according to the description, the kitchen and bathroom share the main sewer pipe, and there should be illegal demolition or illegal construction.

It is judged that it should be the sewer of the kitchen, first through the bathroom, after the toilet is connected with the relevant sewer pipe, it is connected with the main sewer pipe, which leads to the fact that the kitchen is in the process of draining the sewer pipe, the air in the sewer pipe is backlogged, so that the floor drain of the bathroom or the water seal stored in the washbasin hose has a force, resulting in the water of the water seal overflowing outward.

Influence: The effect of operating conditions on δha can be studied by this formula.

The influence of various major operating conditions of the pump system on the effective NPSH δha of the system

The effect of flow rate on the effective NPSH δha of the system.

When the flow rate changes, while other conditions remain constant, the loss of HW due to flow in the suction line is proportional to the square of the flow rate. As shown in the figure, when the flow rate increases, the δha decreases, and the likelihood of cavitation increases.

The effect of the working medium temperature on the effective NPSH δha of the system.

When the temperature of the working medium conveyed by the pump changes, but other conditions remain unchanged, because the corresponding vaporization pressure p v is proportional to the temperature of the working medium, when the temperature of the working medium conveyed by the pump increases, p v increases, resulting in the decrease of the effective cavitation allowance δha of the system and the increase of the possibility of cavitation.

If it is possible to be blocked by gas, you can put some salt to see.

It is very important to prevent sewer backfilling, especially during the rainy season or after a rainstorm. It prevents rainwater from backing up into the interior of the house, causing property damage and sanitation problems. To avoid this, here are some ways to prevent backfilling in sewers:

1.Clean the sewers: Make sure the sewers are clear enough to drain rainwater. Clean the drains regularly to avoid blockages and ask a professional cleaning company to help prevent rainwater from backing up.

2.Installing the Reverse Valve: The Reverse Valve is a very important tool to prevent sewer backfilling. It shuts off automatically and backs up into the house with a waterproof stream when the sewer level rises.

3.Separate drains from stormwater drains: Make sure drains are separate from stormwater drains to avoid backflow. This method prevents rainwater from flowing into the drains, raising the water level of the drains, which can cause irritability.

4.Install a pump: If the house is located in a low-lying area, we can consider installing a pump that can drain rainwater from the inside of the house to avoid backfilling.

The above are some of the ways to prevent backfilling in the sewer, we should regularly check whether the sewers at home are unblocked, or contact a professional service company to help clean up. There are some precautions we can take to avoid property damage caused by sewer backfilling. These methods are very convenient and practical to protect the safety of the home and maintain a good health and hygienic environment.

Hello, here's how.

1. Go to the building materials store (a store that sells decoration materials) to buy two bottles of industrial hydrochloric acid (500ml per bottle, about 2 3 yuan bottle, and some places call tile cleaner).

2. Boil a large pot of boiling water, at least 10,000ml, keep the temperature, and set aside.

3. After stopping the water in the pool for 24 hours, add a bottle of industrial hydrochloric acid from the vegetable washing sink or sewer pipe, wait for 1 hour, and pour all the boiling water first.

4. After all the boiling water is finished, add a bottle of industrial hydrochloric acid, and after 1 hour, pour a pot of boiling water.

1. Check valve or check valve can be installed first to prevent sewage backfill, check valve or check valve is a kind of stop valve in the gas and water circuit, which can play the role of one-way conduction.

2. Or to renovate your own sewage pipe into an independent one, go directly to the outside of the building, and then to the first floor, dig a groove to put the pipe into the sewage well, and keep the sewer unobstructed, and there will be no sewer blockage and sewage backfilling.

Sewer is a very important infrastructure in the city, which can discharge sewage, rainwater and other wastes to the sewage treatment plant for treatment, and play a role in maintaining urban environmental hygiene and purifying water sources. However, in some special cases, such as during heavy rains, sewers will have backflow problems, which will cause serious pollution and disasters to the city, and effective measures must be taken to deal with them.

Here are some of the methods commonly used to deal with sewer backfills:

1.Pipe cleaning: Removing debris and sediment from the pipes can increase the flow capacity of the pipes as much as possible and reduce the chance of backfilling.

2.Pipe dredging: If there is a blockage in the sewer, it is necessary to dredge it in time to ensure the smooth flow of the sewer as much as possible to avoid the occurrence of backfilling.

3.Drain gates: Install a back-up gate at the end of the sewer to prevent backfilling. When the water level at the end of the sewer rises to a certain height, the floodgates automatically close to prevent backfilling.

4.Drainage wells are provided with sluice blind ruler plates: For drainage wells, sluice plates can also be set up to avoid backfilling. When the water level rises to a certain height, the gate automatically closes, preventing the flow of water into the trapped drainage well.

5.New stormwater ponds and infiltration pits: When it rains, you can increase the number of stormwater ponds and infiltration pits to alleviate the problem of backflow caused by excessive rainwater.

In short, to avoid the problem of sewer backfilling, it is necessary to take a variety of means and adopt appropriate treatment methods to ensure the smooth flow and normal operation of sewers.

(1) You can choose a pump with a larger head and add a check valve.

2) The easier way is to install an overflow branch pipe on the pipe under the floor (a water bend needs to be set up to prevent odor).

The reason for the sewage backflow is that the lifting head of the pump is insufficient, and a check valve is not set at the outlet of the pump.
