When the water is warm, the height to which a pump can lift it **decreases due to reduced viscosity**.
As the temperature of the water increases, its viscosity decreases, which can lead to increased turbulence and energy losses due to friction in the pump and piping. While warmer water has higher vapor pressure, the primary factor affecting pump performance is the reduced viscosity leading to increased frictional losses.

It Decreases due to increasing vapour pressure.

Yes, you are right @Varsha.

The right answer will be (decrease due to increase in vapour pressure) because as we increase the temperature the no of vapour will increase thus vapour pressure will increase.

"decreased due to increased vapor pressure".
This is the right answer.
This is the right answer.

Suction lift decreases as the water temperature increases since warm water contains more entrained air.
