It doesn't take a plumbing genius to figure out that insufficient water pressure is often the result of a constriction or obstruction somewhere in your lines. Unfortunately, there is a world of difference between such general causes and the specific issue plaguing you. If you would like to learn more about narrowing down the probable source of your low water pressure, read on. This article will introduce you to three common symptoms and what they tend to mean.
Your pressure starts off okay but rapidly decreases.
If you have noticed this problem, chances are you have also found that it seems to affect each fixture in your home to the same degree. After coming out nice and strong for a few seconds, the stream will abruptly taper down to a dispiriting trickle. The fact that this issue affects all of your home's plumbing usually means that the obstruction is located inside of the main water pipe.
So long as your system is idle, water is able to make its way past the constriction and fill up the various pipes in your home to their maximum capacity. That's why things start off okay when you open the tap. Soon, however, that limited supply of water is exhausted, and the clog's true nature begins to present itself. Fortunately, this problem can often be easily eliminated by hiring a plumbing contractor to use a heavy-duty drain snake to clean out your main water supply line.
Your pressure varies from one fixture to another.
As you can likely already deduce, the limited scope of this issue means that it does not stem from a system-wide constriction. On the other hand, the source of the poor pressure is local to the affected fixtures. Of course, it isn't always so simple as one sink or tub whose water pressure is off—not unless the clog happens to be located in that fixture's exclusive hardware. Rather the problem may affect a wing of your home whose plumbing fixtures are all fed by a single supply line.
You've got one particular faucet whose water pressure is off.
Pressure problems occurring at the level of a single faucet are often the result of debris or mineral build up inside of the aerator. The aerator is the screw-on assembly that makes the water come out appearing all white and fuzzy. It also helps to reduce your water bill by throttling the amount of water passing through. Yet when foreign matter builds up on the inside of the aerator's screen, it can cause the water to come out at no more than a trickle. Fortunately, disassembling and cleaning the aerator is all it usually takes to get things working once more.
