Common Causes of Low Water Pressure and How to Fix Them

Understanding Low Water Pressure

Nothing is more frustrating than stepping into the shower only to be greeted by a weak trickle of water. Low water pressure can disrupt your daily routine and make simple tasks, like washing dishes or doing laundry, feel like a chore. If you’re dealing with low water pressure in your home or business, it’s important to identify the cause and take the appropriate steps to resolve it.

At Aqua Plumbing and Heating Ltd., we understand how essential proper water pressure is for comfort and convenience. Our team of professionals has been serving Edmonton residents since 1985, providing expert plumbing and heating solutions. Whether you need residential, commercial, or emergency plumbing services, we are available 24/7 to tackle any issue, including low water pressure problems.

1. Clogged Pipes
   One of the most common culprits behind low water pressure is a clogged or blocked pipe. Over time, mineral deposits, debris, and even small objects can accumulate inside your plumbing system, restricting water flow.
   How to Fix It:
   DIY Solution: If you suspect a clog in an exposed pipe, you can try using a plumbing snake or a vinegar and baking soda solution to break down minor buildups.
   Professional Solution: If the clog is deep within the plumbing system, professional hydro jetting or pipe replacement may be necessary. Aqua Plumbing and Heating Ltd. can assess your pipes and provide effective solutions to restore water pressure.
2. Corroded Pipes
   Older homes with galvanized steel pipes are particularly prone to corrosion. Over time, rust and mineral deposits narrow the interior of the pipes, reducing water flow and ultimately leading to low water pressure.
   How to Fix It:
   DIY Solution: Unfortunately, there is no true DIY fix for corroded pipes. Temporary solutions, such as using a pipe descaler, may provide minimal relief.
   Professional Solution: The best solution is to replace old galvanized steel pipes with modern materials like copper or PEX. Our team at Aqua Plumbing and Heating Ltd. can evaluate your plumbing system and recommend the best course of action.
3. Faulty Pressure Regulator
   A pressure regulator is designed to maintain a safe water pressure level in your home. If it malfunctions, it can cause either high or low water pressure issues.
   How to Fix It:
   DIY Solution: You can check your pressure regulator using a water pressure gauge. If the reading is below 40 psi, you may have a faulty regulator.
   Professional Solution: Replacing a pressure regulator requires plumbing expertise. Our skilled technicians can quickly diagnose and replace a failing pressure regulator to restore normal water pressure.
4. Municipal Water Supply Issues
   Sometimes, the problem isn’t within your home at all—it could be due to municipal water supply issues. Construction work, damaged water mains, or high demand can lead to temporary low water pressure.
   How to Fix It:
   DIY Solution: Check with your local water supplier to see if there are ongoing issues in your area.
   Professional Solution: If municipal water issues persist, a professional plumber can install a booster pump to increase water pressure in your home.
5. Leaks in the Plumbing System
   A hidden leak can drastically reduce water pressure by diverting water away from your fixtures. Leaks can occur in underground pipes, behind walls, or under sinks, making them difficult to detect.
   How to Fix It:
   DIY Solution: Look for visible signs of leaks, such as water stains, mold growth, or an unusually high water bill.
   Professional Solution: If you suspect a leak but can’t find the source, a professional plumber can use specialized equipment to locate and repair the leak, preventing further water loss and restoring pressure.
6. Issues with the Water Heater
   If you notice low water pressure only when using hot water, your water heater may be the problem. Sediment buildup in the tank can restrict water flow, leading to decreased pressure.
   How to Fix It:
   DIY Solution: Try flushing your water heater to remove sediment buildup. Most manufacturers recommend doing this annually.
   Professional Solution: If flushing doesn’t improve water pressure, there may be a more serious issue, such as a failing heating element or corroded tank. Our experts at Aqua Plumbing and Heating Ltd. can inspect and repair your water heater.
7. Shut-Off Valve Problems
   The main shut-off valve controls water flow into your home. If it’s not fully open, it can lead to low water pressure throughout the house.
   How to Fix It:
   DIY Solution: Locate the shut-off valve and ensure it is fully open. In most homes, this valve is found near the water meter or where the main water line enters the house.
   Professional Solution: If the valve is damaged or stuck, it may need to be repaired or replaced by a professional plumber.
