Have you ever wanted that shower experience of having strong water come from the pipes only to receive very little and very weak water?
Low water pressure is one problem many people experience at home. The pressure might be affecting the whole building and the worst of all, there will be absolutely no way that you can wash the dishes since the pressure of water is too low for the task. Many Americans face this challenge of low water pressure regardless of where they are located. Even people living in row houses in Boston, Texas, and California condos experience this problem.
What should encourage you is the fact that there are many simple ways to solve this issue without involving any expensive repair work and even worse, there is no need to hire a plumber. All these solutions are available within your reach and will take you five minutes to solve the problem.
In this blog post, we will share the common causes of low water pressure in homes as well as how to fix the same.
The Silent Culprits: Why Your Water Pressure Drops
Low water pressure almost never occurs spontaneously. Instead, one (or more) of these frequently observed causes will probably be responsible for low pressure.
Partially Shut Off Valves
The easiest explanation is also the most common oversight: Your main shut-off valve or water meter valve might not be fully shut off. These two valves regulate the water flow in your home, and a partially shut-off position could have dramatic consequences on your water pressure. Look for these two valves (near your water meter or at the point where your main water line enters your home), and twist them clockwise all the way to fully open.
Clogged Aerator/Shower Heads
Gradually, over time, mineral buildup will occur in your water lines, blocking the water from flowing properly and causing poor flow rates. Faucet aerators and shower heads are most susceptible to this issue, especially in areas that experience hard water problems in the Midwest and Southwest.
Mineral Buildup Inside Pipes
If your home experiences hard water, then there may be buildup called limescale—a whitish-gray film—that develops in your pipes. Over time, as more buildup occurs, this will narrow the pipe’s inner diameter and slow down the flow rate.
Corroded Pipes
Older homes with galvanized steel pipes will face issues of pressure. The pipe lasts only 20 years, after which corrosion begins. Rust and scales on the inside of the pipes reduce water flow significantly. If your house is more than 30 years old and no pipes have been replaced yet, corrosion could be the source of your issue.
Excessively High Usage
The simultaneous use of multiple devices that consume lots of water could cause this issue. Using your washing machine, dishwasher, and taking a shower all at the same time means less water is available for your needs.
Municipality Problems
On some occasions, the reason why your pressure is low is not located in your home. Changes in regulations regarding municipal water supply, issues with infrastructure, or even drought can create problems for you. People living on the same water line may also be consuming lots of water, hence lower water pressure.
Defective Pressure Reducing Valve
Most houses have a pressure reducing valve that helps keep water pressure steady. This device may become faulty or improperly adjusted, thereby losing its purpose. This regulator valve looks like a bell, and it’s usually near the main valve.
Leaky Pipes
If there is a leak in your pipes somewhere, in the ground or inside walls, it could be causing your pipes to lose pressure without even losing any water at all.
Quick Fixes You Can Try Today (No Plumber Needed)
Try out these easy fixes that will solve most of your low-pressure issues before hiring a professional.
Descale Your Faucet Aerators and Shower Heads
This is not only the quickest and cheapest solution, but also very easy to do. Simply detach your faucet aerator or shower head and soak it in white vinegar and warm water for half an hour. After that, gently clean it with an old toothbrush, rinse it, and put it back. Test your pressure right away and you’ll usually notice immediate improvement.
Test and Regulate Your Water Pressure
First, find your water pressure reducing valve (located close to where your water enters your home). Measure your current water pressure using a pressure gauge which you can easily buy for about $10-$15 from any hardware store. The normal range for residential houses is between 40–60 psi. Adjust the valve upwards slightly with a small screw on top to raise pressure.
Make Sure That Every Valve Is Opened
Go around the house and make sure all of the valves are opened. Look under the sink, behind the toilet, near the water heater, and the main valve. The valve must be turned all the way (clockwise), otherwise, it will significantly reduce the water pressure. If it is even partially closed, the pressure will drop twice.
Identify Leaks
Look at your water meter and take readings in the morning and then again after two hours without using any water. If there is a difference between the readings, then there is a leak somewhere. You should also look for any traces of wetness or discolorations near your sinks and around your appliances.
Change Your Faucets and Showerhead
If simple cleaning cannot improve the situation, then consider replacing your faucets and your showerhead with those of the high-pressure kind. There are some new technologies which allow creating the feeling of high pressure with relatively low water consumption.
When It’s Time to Call a Professional
There are certain instances where you will require the services of an experienced plumber. Contact an expert plumber when you realize:
- Corrosion of pipes in your house – Full repiping will be needed in houses with old galvanized steel pipes (over 20 years)
- Reduction in pressure in water flow only during certain times – This means there is a problem with the municipal supplies or within your immediate area
- The problem remains the same after all DIY techniques – This indicates that the problem could be deeper
- Leaking pipes resulting in wet areas, stains, and mold formation – This implies that hidden leaks have emerged
- A sudden reduction in water pressure – Rapid reduction indicates serious breakages or failures in regulators
An expert plumber can conduct pressure tests and detect any hidden leaks in your pipes.
Prevention Tips: Keep Your Water Pressure Strong Long-Term
It’s much simpler to prevent low pressure than address it after the fact. The following tips will help you ensure high water pressure throughout the year:
Install a whole house water filter to trap any particles that would otherwise enter your system. If you have hard water, install a water softener to stop mineral deposits from building up. Flush your aerators and shower heads on a 3-6 month schedule. Check your water bills for unusual spikes, which may signal an undetected leak. If you have old galvanized pipes, replace them with copper or PEX piping.
If you have low municipal pressure, consider adding a pressure boost pump. This kind of device is very common in remote areas, or in houses built on hills where the water has to flow uphill.
Final Thought: Don’t Live with Weak Water Pressure
Your water pressure doesn’t have to remain low all the time. It’s usually caused by problems that can easily be solved using easy and affordable remedies. Begin with the basics of cleaning, pressure test, and check valve before jumping into conclusions. Some people are surprised when they learn the cause of their problem can be solved within half an hour.
If the situation goes beyond your ability to repair it, then there is need for professional assistance. Contemporary plumbing options such as pressure boosters, installation of new pipes, and advanced fixtures can literally change everything. Your bath must make you feel fresh, your dishes must wash correctly, and your tasks become easier.
FAQs
1. What is normal water pressure in a house?
The normal water pressure in a house is between 40 and 60 pounds per square inch (psi). The perfect range for most houses is between 50 and 55 psi. Anything less than 40 psi is considered low pressure while anything above 80 psi is considered high pressure.
2. How can I find out whether low water pressure is a problem with just one fixture or all of them?
This will depend on the results after trying multiple sinks and showers in the house. If all fixtures exhibit low water pressure simultaneously, then the problem is not isolated.
3. Can low water pressure harm my plumbing?
Low water pressure is not in itself harmful. Low pressure indicates a problem such as corrosion or a pipe clog. Very high pressure can damage pipes, so keeping the correct pressure levels is essential.
4. What is the cost of repairing low water pressure?
Basic fixes such as cleaning aerators are free. Pressure gauges cost around $10-$15. Pressure regulators replacement is estimated at $150-$350 with labor charges. Complete repipe in cases of corrosion will cost you between $3,000-$15,000. Booster pump prices are estimated between $500-$1,500.
5. Do I need a water pressure booster pump?
If you have tried everything else and are experiencing persistently low pressure (less than 40 psi), consider installing a pressure booster pump. Such devices are beneficial when your house is located on a hill, or when you live off the grid on a farm using a private well. If you are unsure if it is a good solution for you, consult with a plumber.
