How To Troubleshoot Low Water Pressure in Your Home

A lack of water pressure in your house can cause numerous problems in your day-to-day life. Learn how to troubleshoot low water pressure in your home and when you should call our plumber for help.
How Do You Know If You Have Low Water Pressure?
You can purchase and use a test gauge on an outdoor water faucet or an indoor laundry sink to determine your water pressure settings. Any measurement below 30 psi indicates that you need water pressure troubleshooting.
If you don’t have a test gauge available, some signs that you may have low water pressure at your home include:
- Weak water flow from faucets
- Poor performance from automatic sprinkler systems
- Dishes that remain dirty after running the dishwasher
- Banging sounds from the water pipes
Water Pressure Troubleshooting Tips
Learn more about some of the water pressure solutions you can deploy to try to improve your water performance.
Look at Your Water Usage Patterns
If you have intermittent problems with water pressure, track how you’re using water. If you’re watering the lawn at the same time one kid is showering while the other one is trying to do laundry, you may notice water pressure issues.
You simply might have to run fewer appliances that demand water at the same time to alleviate your low water pressure issues.
Check Your Valves
You may have multiple shut-off valves spread across your plumbing system. You need these valves to cut off water flow in case of a leak or broken faucet.
If one of the valves is partially turned, you may have unusual water pressure issues.
Inspect your plumbing system to make sure all the shut-off valves are fully open. Don’t forget to check the valve on your main water supply pipe.
Pressure Regulator Problems
Some homes may have a water pressure regulator installed on the main supply line to prevent excessive water pressure from damaging pipes. If the regulator is malfunctioning, it could reduce the flow of water too much, causing issues for you.
Contact our expert plumbers to measure the performance of the regulator and to replace it if necessary.
A Gradual Loss of Water Pressure
If you’ve slowly lost water pressure over months, you may have corroded, leaky, or clogged pipes. The problems associated with these issues occur slowly over time.
Our professional plumbers can inspect your pipes to determine whether we’re seeing signs of corrosion or leaks that need repair or replacement. If you have clogs from limescale buildup, we can install a water softener to try to prevent additional buildup.

“Price was more than reasonable, especially last minute”
What a great local family company. Had a little issue today (Saturday). Gave them a call. The lady said she would have someone here between 3 & 5. It was at 1 when I called. 3:00 on the nose Don was here. Don was very friendly and had the broken pipe fixed in no time at all. The price was more than reasonable, especially last minute on a Saturday.

“Took care of it in no time”
Plumbing technician Dean Taylor came over last week to set up a line so I could get a dishwasher installed. I didn’t have the proper setup but he took care of it in no time! Now the installers will have no problem doing it. He was very knowledgeable and professional. I will definitely have him come back for other plumbing jobs. From start to finish everyone I spoke to was very helpful! Their customer service is outstanding!

“Gave me great peace of mind”
Great experience with TFP! They were super professional and friendly, exactly on time, fixed the issue, AND were inexpensive. I received a text when to expect them with a picture of my two technicians (Dean & Kade) AND their license numbers included in the text. This gave me great peace of mind as I am a woman that lives alone. I highly recommend Thompson Family Plumbing!

“Integrity and honesty”
I cannot say enough good things about this amazing company. We found them through reading other people’s reviews on Yelp. They have helped us with a plumbing issue and installing a new hot water heater. They are prompt, reasonable, and incredibly helpful. John’s integrity and honesty along with the rest of the crew would make it a pleasure to recommend to anyone and everyone.
