Water pressure is one of the most important factors in maintaining a well-functioning plumbing system. Too high, and it can damage your pipes and fixtures. Too low, and it can make everyday tasks frustrating.
If you’re experiencing water pressure issues in your home, you’re not alone. In this blog, we’ll explore common causes of high and low water pressure and how our professional plumbing solutions can help.
Why Is My Water Pressure High?
While strong water pressure might seem like a luxury, excessively high pressure can cause significant plumbing problems. Here are a few reasons why your water pressure may be too high:
1. Faulty or Missing Pressure Limiting Valve
A water pressure limiting valve helps control the pressure coming into your home. If it’s malfunctioning or missing, you could experience excessive pressure that may lead to leaks and pipe damage.
Solution: We can test your water pressure and install or replace a pressure limiting valve to keep it within a safe range (typically between 300-500kpa).
2. Community Supply Issues
Some homes receive high water pressure from the local water supply, especially during off-peak hours.
Solution: Installing a pressure limiting valve either close to the meter, or where the water supply comes into the house. This will stabilize your water pressure and reduce the risk of long-term damage.
Why Is My Water Pressure Low?
Low water pressure can be just as frustrating as high pressure. If your sinks, showers, or appliances are running weakly, here are some possible causes:
1. Blocked Pipes or Fixtures
Over time, mineral deposits, residue, and debris can build up in your pipes and mixers, restricting water flow, and also pipe sizing may be affecting pressure when two or more fixtures are in use simultaneously.
Solution: A plumber can inspect your pipes and clean or replace any blocked fixtures. In severe cases, re piping may be necessary.
2. Leaking Pipes
Hidden leaks in your plumbing system can cause a drop in water pressure while also increasing your water bills.
Solution: A qualified plumber can perform a leak detection test and repair or replace any damaged pipes.
3. Community Supply Issues
If your neighbours are also experiencing low pressure, the issue may be with the community water supply.
Solution: Contact your local water supplier to check for maintenance or supply issues. If the problem persists, a plumber can install a booster pump to increase pressure in your home.
4. Old or Corroded Pipes
Older galvanized steel pipes can corrode over time, leading to restricted water flow.
Solution: If your home has outdated piping, re-piping with modern pipework may be the best long-term fix.
5. Partially Closed Valves
Sometimes, the main shut-off valve or water meter valve isn’t fully open, restricting water flow.
Solution: Check that all valves are fully open. If you’re unsure, a plumber can inspect and adjust them for you.
