7 Plumbing Issues That Are Causing Low Water Pressure In Your Home


What is Causing Low Water Pressure

Dribbling is great for basketball, but when your water only comes out of the tap in dribbles, there’s a problem!

Ever since indoor plumbing became widely available in the 1930s, people have been dealing with the problem of low water pressure.

The good news is, it is usually simple for a plumber to diagnose the cause of your low water line pressure and get things fixed up for you. This article takes a look at some of the common reasons for low water pressure. Read on to learn what they are!

1. Build Up

Build up of debris in your pipes can cause a decrease in your water flow pressure. As sediment or other contaminants collect in your pipe, they constrict the flow of the water, leading to lower pressure, or in some cases, complete clogs.

There are a number of ways that these contaminants can enter your pipes.

If you have hard water in your area, then that means that there are already trace minerals in your water supply. Those trace minerals can build up in your pipes over time. Small cracks in your pipes or the lines outside your home can let in small debris like sand.

As your pipes age, they begin to corrode. Though most pipes should last for 20 years or longer, eventually they may succumb to corrosion. When pipes corrode, little bits of the pipe itself will come off and become sediment that can collect in your pipes.

A qualified plumber will be able to assess the problem and either flush out the debris or replace the pipes, restoring your water pressure.

2. Clogged Aerators

Sometimes, the solution to your low water pressure problems is at the very end of the line. The aerator is the bit at the end of the faucet that makes the water come out of the faucet a little bubbly. It’s used to help conserve a bit of water and as the last filter for any dirt that might be in the tap water.

Aerator screens are susceptible to clogs and build up, and when they clog it can cause a drop in water pressure. The same is true for shower heads; the water pressure in your home may be fine all the way up until just before it is ready to come out of the showerhead, and then clogs in the head itself cause the problem.

Luckily, cleaning out your aerator is such a simple job, you can do it yourself in no time flat. If you clean out your aerator and showerhead and the problem persists, then it’s time to call a plumber because you’ve got a bigger problem on your hands.

3. Low Capacity

Another cause of low water pressure is having a system that just can’t keep up with your needs. Having multiple bathrooms is a luxury, except when your system doesn’t have enough capacity to use them at the same time. If this is the case, you may need to explore what options you have for increasing your capacity.

You also may experience low pressure specifically with hot water. This could be due to your hot water heater not being able to keep up with your hot water needs. It could also be due to a faulty water pressure valve on your hot water system.

4. Valve Problems

There are a number of water shutoff valves throughout your home. They make it possible for you to perform repairs and maintenance on your water system, but they can also be the source of low water pressure.

If you had a repair done and a valve was only partially reopened, it would cause a decrease in flow and water pressure. In the same way, a broken or stuck valve could cause similar issues.

5. Water Leaks

Leaks can be another source of your water pressure dropping. Usually, if a leak is the cause of your low water line pressure, you will notice a sharp drop in water pressure rather than a gradual one. Leaks are typically obvious because you will notice water where it is not supposed to be, but occasionally you may have a leak underground or somewhere that you cannot see easily.

If you suspect a leak, it is important to call a plumber right away. Water can cause a whole host of structural damage to your home and makes mold growth likely.

6. Faulty Water Pressure Regulator

Some homes are equipped with a water pressure regulator because the pressure coming from the city water main is actually too high. The problem is, if that regulator fails, it may go too far the other way and cause you to have low to no water pressure. If you seem to have intermittent periods of intense water pressure and then practically none, it may be a problem with the regulator.

7. Municipal Supply

Sometimes your low water pressure problems aren’t even from your own home. Occasionally, there may be a city-wide problem. In the same way that your pipes can clog with debris, so can the city pipes.

Check with your neighbors and call your city if you experience a drop in water pressure and can’t find any other cause.
