This can be easily solved by installing pressure regulator, but pressure regulator only works to cut off the too high pressure part of story.
For low pressure part of story, pressure regulator can't do you anything.

That's why I suggested, in order to have a good water pressure, installing a booster pump to have a constant steady pressure is always preferred.
As you never know how will be the direct supply pressure, it does fluctuating all the time, as one main water supply is shared across the housing area generally.

Booster pump + pressure tank installation combo is the good solution nowadays.
Pressure tank eliminate the constant needs to start up the pump whenever you open the tap everytime, that reduces the wear and tear of the booster pump, and electricity consumption.

yes, fully agree that is the best solution, provided got sufficient budget

Here is the water tank bypass that my neighbor have done earlier.

My other place have the same .... done by the previous owner. The downside is during water disruption, the water pressure from the reserve tank takes a long time to to build up.

I think it is still safer to do bypass since the main water source are strong enough. My house developer use tank water for the whole house except wet kitchen and dry kitchen which made us suffer for the low water pressure.

Another downside of a bypass system is when more than one place is using at the same time, the pressure will drop .... similar to the water flow from the reserve tank.

Otherwise, the pressure is good for the whole house for single usage.

If you want good pressure for those using reserve tank, a pump will be your solution.

Btw, I prefer those reserve tank outside rather than hidden in the ceiling ... easy for any repair

for me as long as the water pressure is stronger than original reserve water tank pressure will do. even more than one places are in use it is still stronger. my reserve tanks are built on the roof top which is external.

water disruption rarely happened at my area and even the worse Sungai Selangor pollution incident which had happened few times doesn't affect my area so far.

Reserve tank water have to be used frequently, otherwise algae and bacteria will accumulate.

I didnt say the system is no good. Is just sharing the experience that I have faced. If you like it, then good.

Btw, the bypass system is yours or neighbour ?

I did bypass and a 1 way valve if there is disruption supply fr mains(which happens often). The water tank has output to washing machine and this will ensure the storage water is used daily.

Bypass is way to go, saves money on long term electricity, pump servicing, have done these on all my house incl those rented out. Only thing here is make sure on annual basis, need to open & clean the valve outlet at various toilet so that no sand is blocking at the valve
