6 Common Culprits of
Low Water Pressure in
Brought to you by:
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 of the
1. 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.
2. 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. 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.
3. 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.
5. 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.
6. 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. Remember that
incorrect installation of pipes may cause further
problems down the track, or worst, can be an
extremely costly exercise. When experiencing low
water pressure or any other plumbing issues for
that matter, it’s best to have plumbing experts
like Aqua Maintain take a look.
