My hot water doesn't stay hot for very long when I am running it. Does
this mean that I have to get a new water tank or is there something I can
do. Also, I don't have alot of water pressure comming out of my hot water
side on my faucet. It is starting to get worse and I don't know what to
There are many possibilities, for this. If your water is made by a coil, on
a boiler, it could be clogged. You could have some galvanized piping, which
over time gets restricted internally. You may just have to turn up the
thermostat on the water heater
What type of tank? Gas or electric? You may have a heating element gone bad
or the thermostat of a gas heater not functioning properly. Or you kids may
have been playing around it and changed the heat setting. Lack of pressure
indicates clogging of the flow, possible mineral deposits building up.
Keep in mind, if you live in a cold areas, the incoming water is getting
colder too and exacerbating the problem.
In addition to this excellent advice, let me add one more: examine the piping
going into the water heater, to make sure it's connected properly. When we
bought our previous house, I soon discovered that the water heater would
provide very hot water for six or seven minutes, which would then abruptly
become tepid and stay that way as long as the hot water continued to run.
It turned out that the pipes had been connected backward when it was
installed: hot to the inlet, and cold to the outlet. So the hot water was
withdrawn from the bottom of the tank (right next to the heating element), and
cold water entered the tank at the top -- where it promptly sank to the
bottom, chilling the entire contents. Reconnecting the pipes properly solved
