If you’ve noticed a decrease in water pressure throughout your home or at specific fixtures like your shower head or kitchen faucet, you’re not alone. As Kalispell’s trusted plumbing experts for over three decades, we’ve diagnosed and resolved countless water pressure issues for homeowners across the Flathead Valley. To help with your low flow woes, our plumbers have put together a list of the most common causes of low water pressure and their solutions.
Common Causes of Low Water Pressure Throughout Your Home
1. Main Water Valve Issues
Your home’s main water valve controls the overall water flow into your property. Sometimes, this valve can remain partially closed after maintenance work. In fact, according to the International Association of Plumbing and Mechanical Officials (IAPMO), a partially closed main valve is one of the most common causes of whole-house low water pressure. Check both your home’s shutoff valve (typically located near the foundation where water enters your home) and the municipal water meter valve.
2. Hard Water Buildup
According to the Water Quality Association, about 85% of American homes have hard water, and it’s common in the Flathead Valley. Â High levels of minerals like calcium and magnesium in the water can accumulate in your pipes over time, gradually narrowing your pipes’ diameter, reducing water flow and pressure throughout your home. Installing a water softener can prevent future buildup and protect your plumbing system. Water softeners are recommended to improve water quality and extend the life of your plumbing system.
3. Failing Pressure Regulator
A pressure regulator is a control valve that reduces the incoming water pressure from municipal water lines to a safe level for your home. They maintain household water pressure between 45 and 80 psi. When this device fails, it can cause either extremely high or low water pressure throughout your entire home.
4. Corroded Plumbing
Older homes with galvanized steel pipes often experience decreased water pressure due to internal corrosion and mineral buildup. The American Society of Home Inspectors notes that galvanized pipes typically have a lifespan of 20-50 years. The buildup gradually restricts water flow, leading to decreased pressure throughout the home.
Localized Water Pressure Issues
1. Clogged Aerators
If you’re experiencing low water pressure at a single faucet, the aerator might be clogged with mineral deposits. Soaking aerators in vinegar dissolves the minerals and help keep them clean. Many aerators can also be replaced if the buildup becomes severe.
2. Water Heater Problems
Low hot water pressure specifically can indicate issues with your water heater. Sediment buildup in the tank or problems with the shut-off valve are common culprits. Sediment buildup can significantly reduce water heater efficiency and pressure. Flushing the water heater tank annually can prevent buildup.
3. Leaking Pipes
Hidden leaks can cause pressure drops at specific fixtures or areas of your home. Signs of leaking pipes include:
- Unexplained increases in water bills
- Damp spots on walls or ceilings
- Musty odors
- Sound of running water when all fixtures are off
Why Hire a Licensed Plumber?
While some water pressure issues can be diagnosed through visual inspection, many require professional expertise and specialized equipment to properly identify and repair. Here’s why you should trust the licensed plumbers at Central:
