Low water pressure can be a tricky problem to diagnose. As annoying as it may be, your local Houston plumber can look things over and see where the problem lies. It may be as easy as cleaning out mineral deposits that have accumulated over time, to water leaks in your pipes, to debris in the water clogging the line. Plumbers deal with this sort of problem often, so you will be in good hands.
If you know you have an older home, chances are you have iron pipes. Iron pipes tend to rust and then the rust can break down and plug aerators, valves, and anywhere there is a restriction in pipes. Debris can also include algae, debris from inside the water heater, even rust or gravel when the city works on water mains. If you suspect debris in your water line or if your sink faucet doesn’t work well, take off the aerator (the little cylinder screwed on the end of the spout) and see how the water flows without it. If the water flow is fine, clean or replace the aerator. If the water flow is still bad, the problem is farther up the line. You can then shut the water off to the sink, disconnect the faucet and then turn the water on to see if the flow is good there. If it’s not, the problem is even farther up the line.
You can then think about the pressure regulators. This is a device shaped like a bell usually found below the hose connection in the front of your home, although some homes might have it in a different location. If the pressure regulator goes bad or stops working, it may cause low water pressure in some or all of the fixtures in your home. A Houston plumber can easily replace or fix a regulator at a very reasonable cost. This job is better left to a licensed technician, as it can be a tricky project to tackle.
