Thanks Bro. I actually shared similar thought on the possibility of the tank running empty but the risk is still there. Suppose the tank is empty and the pipe is filled with air, when the water tank is refilled with water again, the water flow will be blocked by air in the pipe. That's why I was told to install pump to help draw out air trap in the pipe so water can flow again. Is this true? RM1800 is unreasonable to me! I am still trying to survey what is in the market.
What is the difference between class 6 and class 7 pipe btw? Which one is more suitable and durable for apartment/home use?
@Zheilwane, any comments/recommendations from you?
Depends on the pump type. Cheap pump will get water jetting when pump automatically switch on and off. it is because the pressure switch turn motor on and off abruptly. When motor is turned on the pressure build up in pipe but then the water out is less casing pump to switch off and when pressure low again the pump on and so on, causing water jetting. More expensive one have bigger bladder tank thus less water jetting effect.What is the difference between class 6 and class 7 pipe btw? Which one is more suitable and durable for apartment/home use?

Nowadays, high end pump is using inverter to vary motor speed, thus the pressure in pipe is consistant. This will let water flow smoothly. The inverter type even no need to have bladder tank.
The RM1800 probably this high end type. You need to ask. I know that Grundfos Scala2 is around RM1700~1800. This is real constant pressure pump.
