Why you might have low water pressure

Water is necessary for so many of our daily activities and to have it reduced to a dribble is frustrating. Our experts at Newman and Barker Plumbing explain why you might have low water pressure and suggest ways to get your water freely flowing again.

Where is the origin of your low water pressure?

The first step is to find how widespread the problem is. Is there low water pressure throughout the entire home or just in one area? Is it limited to one tap? Before calling a plumber, we recommend turning on the hot water first. Low hot water pressure could indicate a problem with the hot water system. If you determine this to be the case, contact your plumber. Once you determine it is not a hot water issue, then resume checking all the taps. If the problem is only low water pressure in the sink, check the tap screen and aerator. Mineral build-up or rust can obstruct the water flow right at the tap itself. If this is the case, you can either clean the screen and try again, or it may be necessary to replace completely. While you are checking, go ahead and make sure no other taps need to be cleaned or replaced. For hot water system maintenance tips, click here.

Leaking pipes

Broken or worn pipes are unable to sustain constant water pressure. Leaks and mineral buildup are common reasons for low water pressure, particularly in older homes.

Showerhead problem

If the low water pressure is confined to the bathroom, cleaning or replacing the showerhead with a more efficient version may be a fast and simple solution.

Pressure limiting valves

While the Plumbing Code of Australia and the Australian Standards require pressure limiting valves, so do many manufactures of appliances and fixtures. Many manufactures of taps, showers, hot water systems and washing machines set a maximum inlet water pressure. Water pressure which exceeds their maximum voids their warranty. 

Pressure regulator

Every home is fitted with a master pressure regulator. This device is usually located near the main water main. Despite the fact that the pressure regulator should not need frequent adjustment, they can fail with time.

Clogged pipes

Rust and mineral deposits build up over time and can eventually shut down the water flow.

If you suspect that you have clogged pipes, do not try a DIY project. Pipes run everywhere under your home. It can be difficult to determine where the clog is and then reach to fix it. This is a job for a highly trained plumber.

Overuse of the plumbing system

Even the most well-maintained residential plumbing system does have a maximum supply of water at any one moment. If someone is in the shower while another person is washing dishes, neither may have enough water pressure to get the job done properly. The water has to divide where it’s going and therefore each outlet suffers from low pressure. Being conscious of how much water you use and taking measures to reduce excessive use is not only beneficial for the environment but may help mitigate water pressure problems.

Low water pressure? When to call a plumber

There are so many causes for low water pressure that it can take a while to investigate and discover the root of the problem. If the pressure is limited to one spot, the solution may be simple. If it runs throughout your entire home, we advise calling the professionals. For more information on how we can service all your plumbing needs, please get in touch with Newman and Barker Plumbing.
