How can you get hot water faster at all the bath room it take long time to get hot?

You could install a recirculating pump near your hot water tank and run a pipe from the furthest fixture that has hot water to this pump. This pump would then circulate the hot water back into the COLD inlet of the hot water tank and have hot water available at each fixture when you want. You would require a check valve where the recirculated water enters the cold supply to your hot water tank. CALL A PLUMBER THAT HAS FREE ESTIMATES!!!
