20 years at least, provided the hot water heater is serviced and maintained by a plumber once a year.
That depends on how much water is drawn from the tank and how often it is drawn.
About 4 seconds as it comes crashing to the ground
One gallon of water in the summer would last a person about one day in a hot desert.
three seconds
i don't know how long a water pump should last, but mine just went out on my 2005 TB at 47,000 miles. ugh.
About 25-30 seconds. -Most showerheads emit about 2 -2.5 gpm.
either a 15 gallon tank or a 20 gallon tank
Most are rated for 5-10 years depending on cost.
There is no standard length of time that it takes for a gallon of water to freeze. The amount of time it takes for a gallon of water to freeze can vary depending upon many different things such as temperature.
how long does a water spout last
depends on water pressure, but it should completely fill in 15-20 minutes. the water should be hot in another 20-25 minutes if it has been run completely empty.
They should be replaces every 5 years to ensure energy savings.
