What Do I Do If My Water Pressure Is Low?
Low water pressure is one of those problems that’s hard to ignore. Whether it’s affecting your shower, your kitchen sink, or your sprinkler system, it can quickly become a daily frustration. The good news? Most water pressure problems have straightforward causes—and clear solutions. At Jones Sprinklers, we’ve worked with homeowners across Spokane Valley to identify the problem and get things working properly again.
Start by Checking Your Home Water Pressure
Before jumping to conclusions, it’s important to confirm the problem. One of the easiest ways to do this is by checking home water pressure using a pressure gauge. Attach it to an outdoor spigot or hose bib, and make sure no water is running inside when you test.
A normal reading falls between 40–60 psi. If your reading is below that, you’re officially dealing with low water pressure—and it’s time to figure out why.
Common Causes of Low Water Pressure
There are several common causes of low water pressure, and most of them are fairly easy to check:
- Partially closed shut-off valve
If your main water valve isn’t fully open, it could be restricting flow to the entire house. This is one of the first things to look at when diagnosing water pressure problems and solutions. - Clogged faucet aerators or showerheads
Mineral buildup is a frequent cause of low flow in individual fixtures. Unscrew the aerator or showerhead, soak it in vinegar, and scrub away any debris. - Plumbing leaks
If you’re losing pressure throughout your home and noticing damp areas, pooling water, or higher bills, a leak could be the issue. In that case, a licensed plumber should inspect your system. - Faulty pressure regulator
Not all homes have one, but if yours does, a failing regulator can cause pressure to drop suddenly. If pressure seems inconsistent or unusually low, this could be the reason. - Corroded or aging pipes
Over time, buildup inside old pipes can reduce water flow. If your home has galvanized pipes or is more than a few decades old, it might be time to consider a replacement.
Is the City Water Supply the Problem?
Sometimes, the issue isn’t inside your home at all. If your neighbors are also noticing low pressure, the cause may be on the municipal side. Scheduled maintenance, broken water mains, or seasonal demand spikes can all temporarily affect water pressure in your area. In these cases, your local water provider may already be aware of the issue and working on a solution.
It’s always worth giving them a call before scheduling major repairs or making changes to your plumbing system. A quick check can save you time, money, and a lot of unnecessary troubleshooting.
How to Increase Water Pressure in House Systems
Once you’ve confirmed the issue, here are a few steps you can take:
- Open the main shut-off valve completely
- Clean or replace clogged aerators and showerheads
- Repair any leaks promptly
- Replace or repair a faulty pressure regulator
- Consider repiping if corrosion is restricting flow
These are just a few examples of low water pressure solutions that can make a noticeable difference.
Should You Install a Water Pressure Booster?
If your home consistently suffers from low municipal pressure—especially if you’re in a multi-level home or large property—a water pressure booster can be a smart investment. This device increases pressure at the entry point, giving your whole home a more reliable water supply.
It’s a good idea to consult with a plumbing professional to determine if a booster is the right solution for you.
When to Call a Professional
If you’ve tried the steps above and are still struggling, it might be time to bring in a professional. A plumber can help identify more complex issues and recommend long-term fixes. And if you think your sprinkler system is affected by pressure problems, that’s where we come in.
