Week 8, 26th May

Abang Nasir, peronda, brings me to fire fighting pump house to check the availability of the pump. He explained that if pressure is less than 9 bar, jockey pump is activated while less than 7 bar, electric pump is on. Diesel pump 1 will activate when pressure less than 5 bar and diesel 2 will activate when pressure less than 4 bar.

The procedure of doing the checking is opened the bypass valve to let the water flowing back to water tank. Then manually turn on the electric pump, follow by diesel 1 pump and diesel 2 pump. Reading of discharge pressure and flow of water were taken. After all the reading had taken, the bypass valve is closed and all the pumps were set back to automatic mode.
