Hi bro,

For double storey houses, 1st floor toilets water pressure is rather low because the water tank is only above the ceiling.

I heard people says that if we do not want to install pump, we can also by-pass the pipes by connecting direct to the incoming supply pipes.
By so doing, if syabas no water supply come, the toilets also no water?
Or will it automatically use water from the water tank?

Briefly, how is the modified connections like?

Sorry to revive an old thread... What is the reason that the direct water supply will have higher chlorine content compared to water tank supply? Isn't it suppose the same as the water is from the same source?

Possible to install a regulator after the water inlet to control the water pressure before the supply goes into the house piping, i.e.: install a pressure regulator after the POE filter?

Just thinking how to increase my house water pressure without adding a pump, thinking to install a bypass before the inlet of the water tank to the outlet of the water tank. A check valve + control valve at the bypass piping and the outlet of the water tank will do the trick to avoid overflooding the water tank.

To avoid stagnant water, the supply to water tank will be closed every now and then by the stop cork feeding water to the tank to use up the water in the tank before refilling the water tank again.

Have not consulted any plumber yet... just some ideas after reading through some threads here 

Thank you for the clarification and in-sight to using direct water source which I have not thought about.
Will have to think hard between the two options, water pump or direct water source...

wow... a quick googling on chlorine effects on health show up quite a number of findings/ studies. Will take that into consideration. Thank you. : )

I wouldn't say installing water pump is cost effective, it is expected to perform as required and the initial cost is high not to forget the follow up maintenance cost. It's a hassle-free solution for those who can afford.

Connecting to direct water source has it cons as highlighted, the sudden surge/ drop of water pressure is a concern for me, still thinking what could be done.

Good stuff never come cheap and cheap stuff does not do a good job, most of the time. Need to find a balance between the two and most importantly depends on how much left for the renovation budget   

For future proofing, i planning to pull a power outlet to the water tank first in case a booster pump is necessary.
