Water pressure problems can be a nightmare, and washing your dishes and showering can be both time consuming and frustrating.

However if you put on your detective hat, it’s only a matter of time before you’ll figure out the problem, have it fixed, and forget about it.

Here are some of the most common causes of water pressure problems:


Mineral and Debris Buildup

Dirt, sand, pollutants and other debris can enter your home’s pipes, which are also susceptible to buildup from the tiny deposits that water leaves behind as it travels through your pipes.

Just a tiny amount of sediment can cause a blockage, and make it the cause of low water pressure throughout your house.

The solution? Examine a section of your pipe and check if mineral buildup could be the problem. If you think this is the case, there are plenty of plumbing chemicals on the market which will break down debris and solve the problem.

Buildup of Corrosion

While your galvanised or steel water piping system is intended to last around 20 years, they naturally corrode over the years, and other than completely replacing the pipes there isn’t much that can be done to fix the problem.

While replacing the pipes is an expensive solution, it’s sure to add value to the house, and only needs to be done a few times over a lifetime.



Obviously a leak in the plumbing system of your home will reduce the amount of water pressure throughout your home as the water isn’t flowing where it needs to be. To figure out if a leak is causing your water pressure problems, shut off all of the taps in and outside of your house, and then take the recording on the metre. A few hours later, check back and see if the reading has changed. Attaching a water flow measurement device to different fixtures can allow you to track exactly how much water is being used by different fixtures and appliances as well.

If the reading has increased from the first recording, there’s a large chance you have a leak and you’ll need to call a professional.

Problem with the water supply

Sometimes the water pressure problems have nothing to do with the pipes in your house, and may be a malfunction in the actual water supply.

These systems are also subject to buildups, leaks, and other problems which can sometimes effect your water pressure and water supply. Luckily, you can call your water supplier and ask them to see if their water systems are the issues, and the problem will hopefully be fixed quickly.

Low Water Pressure from the Provider

Many people are unaware that they can test to see if they have low water pressure. Simply buy a water pressure test gauge and make sure it has a hose connection. Screw it onto your hose faucet and make sure all of the taps in your house are of. 45 or 50 psi is quite low, 60 is ideal, and above 80 is too high.

If the city pressure isn’t high enough, it can help to ensure you have large water pipes. This will increase the amount of water, and thus the pressure, and you can also get a pressure boost system installed.
