4 causes of low water pressure in bathroom sinks and other fixtures

Many homeowners have experienced the irritation of dealing with low water pressure at least once - and finding the cause of the problem can be the most frustrating aspect of this common plumbing problem.

With low water pressure in your home's plumbing system, simple daily activities such as showering or washing your hair can be made extremely frustrating and time-consuming.

Read on to learn about some of the more frequent causes of this common but very annoying problem, and some possible solutions to low water pressure:

1. Debris and mineral buildup

Debris such as sand, dirt, and pollutants can enter your home's piping system when a water main fractures. Even without this malfunction occurring, your pipes are susceptible to mineral buildup by the deposits that water leaves behind when traveling through your pipes.

Even a small amount of sediment can cause a blockage in your home's piping system that can decrease the water pressure throughout the home.

The solution to this problem is to examine a section of the pipe to determine if a mineral build-up is the problem. Once the problem has been identified, it can usually be solved through the use of plumbing chemicals to break down and flush out the debris.

2. Corrosion buildup

Although your steel or galvanized water piping systems are intended to last up to 20 years, after this period of time, the inside of these pipes tend to block the flow of water with natural corrosion over the years. In terms of repairing, there isn't much that homeowners can do to completely rectify this problem.

However, replacing the pipes completely is a perfectly viable solution. You should expect a long and somewhat expensive process, but the positive aspect is that it only has to be done a few times in a lifetime.

3. Leaks
It's more or less evident that a leak in your home's piping system will reduce the water pressure throughout the home simply because not all of the water is flowing toward its proper place. To determine if you have a leak, you can shut off all of the water taps both in and out of your home.

Record the meter at this time and come back a couple of hours later to see if the meter has changed. If your water usage has increased at all from your first recording, there's a good chance you have a leak that needs to be repaired by a plumbing professional.

4. Municipal water supply malfunctions
Sometimes your problems with low water pressure may have nothing to do with your home's piping system, but may be caused by a malfunction in the municipal water supply where your water is derived from.

Just like your own piping, these systems are also subject to leaks, buildups, and other problems that can affect the water supply and water pressure.

Fortunately, you can call your local municipal water supply department to determine if the municipal water systems is the issue and if the problems corrected quickly.

If you've determined that your home's low water pressure is a problem best suited to be handled by a professional, make sure you make the right hiring choice.
