When you turn on the taps in your house, whether for a sink faucet or a shower head, and the water pressure feels weaker than normal, there are a number of different possibilities. In most cases, this is a municipal issue that will soon be remedied. But it could also be leaks, hard water build-up, or problems with the water main to your house.
If the low water pressure is coming only from the hot water taps, then the trouble can be narrowed down a bit further. You could have a build-up of corrosion, sediment, or other debris in the hot water lines for the home, but not in the cold water lines. Or … you may have hot water heater problems. If the low water pressure is occurring at all the hot water taps, this is probably what you’re dealing with.
