Water pressure is one of those things we rarely think about—until it becomes a problem. Too low, and you’re stuck with a slow trickle when you shower or wash dishes. Too high, and you could be putting stress on your pipes and fixtures, leading to costly repairs.
In Portland, October is an ideal month to check your home’s water pressure. The weather is mild, rainfall starts to increase, and homeowners are often preparing their plumbing systems for heavier use during the upcoming holiday season.
At Einstein Pros, we’ve seen how water pressure issues—if ignored—can snowball into bigger problems. This guide will walk you through why October is perfect for water pressure checks, how to perform them, and when to call in the pros.
Why Water Pressure Matters
Water pressure in most homes should be between 40 and 60 psi (pounds per square inch). Pressure that’s too low can make everyday tasks frustrating, while excessive pressure can wear down pipes, loosen joints, and damage appliances such as water heaters, dishwashers, and washing machines.
In Portland, seasonal changes can affect municipal water supply conditions and the performance of older plumbing systems. That’s why a regular pressure check is not just a “nice-to-do,” but a home maintenance essential.
Why October Is the Best Time for a Check
- Seasonal Shift in Water Demand – As temperatures drop, outdoor irrigation systems see less use, and indoor water use patterns change. This shift can impact municipal supply pressure.
- Pre-Holiday Prep – October gives you enough time to fix pressure problems before heavy holiday cooking, cleaning, and guest use.
- Avoiding Winter Repairs – Checking now means you’re not scrambling to address issues during colder months when plumbing repairs can be more complicated.
How to Test Your Water Pressure
Testing your water pressure is a simple task that most homeowners can do with basic tools:
Step 1: Get a Water Pressure Gauge
You can buy an inexpensive water pressure gauge from a hardware store. Look for one that screws directly onto a hose bib (outdoor faucet).
Step 2: Find the Right Test Location
Choose an outdoor faucet closest to where the main water line enters your home. This gives you the most accurate reading of your home’s supply pressure.
Step 3: Turn Off Water Inside the House
To get a true reading, make sure no water is running inside—no dishwashers, washing machines, or running faucets.
Step 4: Attach and Read
Screw the gauge onto the faucet, turn the water on fully, and check the reading.
- Below 40 psi – You may have a supply issue or partial blockage.
- 40–60 psi – This is ideal for most homes.
- Above 80 psi – You need a pressure-reducing valve (PRV) or an adjustment to your existing one.
Common Causes of Water Pressure Problems in Portland Homes
- Aging Pipes – Portland has many historic homes with galvanized steel or copper piping that can corrode or scale over time.
- Pressure Regulator Issues – A faulty PRV can cause either high or low pressure.
- Municipal Changes – Temporary adjustments by the city can impact pressure levels.
- Mineral Build-Up – Hard water can cause sediment buildup inside pipes, reducing flow.
Solutions for Water Pressure Issues
Low Pressure
- Check for leaks in visible plumbing.
- Clean faucet aerators and showerheads.
- Inspect and flush your water heater to remove sediment buildup.
- Call Einstein Pros if the issue persists—especially if the problem is isolated to one area.
High Pressure
- Test your PRV. If you don’t have one, consider installing one.
- Replace old or malfunctioning PRVs every 7–12 years.
- Schedule a professional plumbing inspection to ensure your fixtures are safe.
Preventive Maintenance Tips
- Annual Testing – Make water pressure checks part of your yearly October home maintenance routine.
- Flush Your Water Heater – Prevents sediment from restricting flow.
- Inspect Outdoor Plumbing – Check hose bibs and irrigation systems for leaks before winter shut-off.
- Replace Old Fixtures – Newer faucets and showerheads are designed for optimal performance at standard pressures.
