i got the plumber to run a bypass with one way valve at the tank to all the bathrooms on upper floors ($300 incl 3 valves & install) and then bought Joven water heater without the pumps (it cost much lesser compared to those with pump function) yet quiet And believe me the water pressure is good and i save on electricity bills long term and maintenance/investment on water pumps though i still dont pay for water bill as i used less than RM15 a month!
