In rural households where the rain water run off from roof to storage water tank.. Any supply pipe from storage tank to shower head with a 24" water level difference will have adequate pressure..
That said if you are getting water into a storage tank above your head, you will have a good water pressure just attaching a water hose to the base of that water tank..
The problem with pump installers these days is they do not test the water flow into the pump as a standard water pump cannot suction up water.. It must be primed..
You can look at any pictures of water pump and promises of plumbers but the simple fact remains if your pump is above your water level you will have problems ..
I have argued with water engineers wrt their pumps NSPH (Net suction pressure head) and pump curves ..as pump design where the water pump inlet is above the water supply (unless you are installing a well pump)
develops problems..
Choose any reputable brand pump or gravity feed run with standard water pipe sizing to qty of fittings, you will have a good pressure..
whau thanks i have no clue half of what u said , u really are pro, haha i think i consult a proper plumber for this tell him what u said see if it makes sense to him , problem is my area is consider small town most plumber here are not very educated nor professional i think
my storage tank feed water directly from main source not from rain, and is right above the ceiling in my bathroom, the height from my tank to the bathroom floor is around 4 meter, from thank to water heater height is half i think , now my heater is running on the pipe from the main source also from the ceiling beside the water tank diverting downwards to the water heater. The height of the routing pipe to heater is just slighty lower than the heater say 5-6 inches.
does this mean my heater is install to high from the pipe?
ill try take some photo and explain haha thanks for helping bro...
