first of all, I don't know what floor your rented house is on. Generally, there are more restaurants on the first and second floors. Do not rule out the possibility of multiple layers.

if it's on the first and second floors, the municipal pressure will definitely be fine.

don't install the water pump and pressure switch in a hurry.

first, check whether the pipeline and faucet between the water meter and the faucet are blocked by scale (turn off the valve beside the water meter, check the faucet, and check whether there are other connections in the pipeline, which are usually blocked by scale, and check the state of the inner wall of the pipeline).

If everything is normal, it's easy to solve. Call the water company. They have the obligation to help you solve the problem of poor water supply in front of the water meter.

generally speaking, it is not recommended to add pumps and pressure switches, which will increase your input cost and power consumption, and the pumps will generate noise when they are running.

if the location of the store is high (which is extremely low and unlikely), if it is on the third and fourth floors and is a commercial building, follow the above method, but the problem in front of the water meter will be to find a property.

If all other methods fail (in large and medium-sized cities, this situation will be easily solved), then install a pressure switch to control the small water pump, the faucet will run when it is turned on, and the hose will stop running when it is turned off.
