When the outlet of the fish tank is small, the water pump will not be damaged.

According to the information of China Fish Tank Network, when the outlet of the fish tank becomes smaller, the water flow speed will slow down, which may lead to the increase of water pressure in the fish tank. In addition, if the power and flow of the pump remain unchanged, the load of the pump will also increase when the water pressure increases, which may lead to pump damage.

In order to prevent the water pump from being damaged, it is suggested that the outlet of the fish tank should not be too small, and the power and flow of the water pump should be large enough to withstand the pressure caused by the change of water pressure. If it is found that the pump is often damaged, it is suggested to check whether the design and use of the pump are reasonable, or consider changing to a pump with greater power and flow.
