6 Common Culprits of Low Water Pressure in Your Home

Low water pressure is a very irritating problem to deal with for most homeowners. It can be very frustrating and time-consuming. Furthermore, figuring out on your own what’s wrong with your plumbing system can be confusing.

So, what are the common causes of low water pressure in your home? We have listed 6 common reasons below;

Water Supply Malfunctions

There are times when low water pressure occurs when there is seemingly nothing wrong with your plumbing. This is more likely caused by a malfunction on the public water supply system in your area. If you suspect it’s the problem, you should get in touch with your local water supply department to make sure that they are aware of the issue.

Incorrect Pipe Sizes

If you have recently fixed your plumbing system and you are experiencing a drop of water pressure, this may be due to the incorrect pipe size and specifications. This is common to homeowners who are trying to cut their budgets by hiring amateur plumbers or even doing DIY. Indeed, you can save money upfront by choosing amateurs; but the workmanship won’t be the same compared to using a qualified Aqua Maintain plumber.

Mineral Build-Up

Every pipe within your plumbing system throughout the home is susceptible to mineral build-up. Remember that water contains minerals and these can be deposited on the surface of the pipes. Over many years, the slow build-up can block the flow of water. This problem can be solved using a specialised plumbing chemical that can break down the sediments and deposits to be flushed out of the pipes.


If you are using steel or galvanised iron pipes, then corrosion can also be the cause of low water pressure. Similar to mineral build-up, corrosion can cover a huge part of the pipes which can then block the flow of water. However, this is not a quick fix, it would require a complete removal and reinstatement of new pipes which may be a costly exercise.

Faulty Taps & Fixtures

Sometimes, a suspected low water pressure problem in your plumbing system isn’t really about low PSI. The signs of low water output or slow flow may be caused by a faulty tap or fixtures. It is best to check their functionality before concluding a low pressure problem – especially if the fixtures in your home are a bit old. If this is the problem, then some simple replacements will do the job.

Pipe Leaks

Sometimes water leaks won’t be evident, especially if the broken pipes are not visible. Checking this problem can be easy. Shut off all the valves and taps in and out of your home, then record the meter reading. After a few hours, record the meter again and check for a difference. If there is an increase on the readings, then a leaking pipe is your problem.

Friendly Reminder: Although we have provided you with some ideas of what may cause low water pressure in your home, avoid doing the repairs or troubleshooting on your own.
