Reasons of Low Water Pressure in House

INTRODUCTION 
A lack of water pressure (low water pressure) can
be frustrating. Baths may take longer to run.
Your toilet tank may take ages to fill up after
flushing. Washing machines and dishwashers may
have to be put on longer cycles. Sometimes low
water pressure may only affect one appliance,
however if its affecting the whole house, it may
be time to intervene. Here are a few reasons why
your water pressure may be low and how you can up
the flow again.

LOW WATER PRESSURE THE MAIN SHUT OFF VALVE
ISNT OPEN
The main reason is blocked drain of your
pipes. The main shut off valve is located by
your water meter and allows all water into your
house. This is operated by a simple lever. Its
possible that the last person to use it didnt
pull the lever fully leaving it semi-closed. Save
yourself from having to call a plumber in to pull
a lever by giving this a check first. A PSI of 45
to 55 is what you want to look out for do not
let it exceed 80 otherwise this will damage
faucets and washers.

LOW WATER PRESSURE THE WATER METER VALVE ISNT
FULLY OPEN
Another important valve to check is the exterior
one connecting your home to the grid. You most
likely wont be allowed to touch this as it
belongs to your local council, however if youve
recently had a repair or have had flooding
problems on your street, its likely a council
hired plumber may have left the valve slightly
open. Get in touch with your local council to
try and address the problem. It could even be
worth seeing if people on your street have been
receiving a lower water pressure too the
problem may lie higher up the street at another
valve.

LOW WATER PRESSURE YOUR PIPES HAVE BECOME
CLOGGED
Its possible there could be a blockage in one of
the pipes. This is common with old iron pipes,
which can start to build up with limescale and
rust. Youll generally notice this if water
pressure has been slowly reducing over
time. Sadly this is not an easy job and may
involve replacing large sections of piping with a
more modern and durable material. This can be
expensive and many people may hold off replacing
piping until the water coming out of their taps
is barely a dribble. Copper piping is the best
for the job, but is expensive. If youre looking
to cut your costs, plastic alternatives such as
PEX could be ideal.

LOW WATER PRESSURE YOUR PRESSURE REGULATOR IS
BROKEN
If you already have a pressure regulator, its
possible that this is broken. Youll know when a
pressure regulator is failing if theres a sudden
change in water pressure. Water may start coming
through unusually slowly. In some cases, the
regulator may even have the opposite effect and
create a pressure spike, causing too much water
pressure. As previously mentioned, this can be
damaging to your piping, wearing down faucets and
washers that were not built for such
pressures. A plumber may be able to fix a
regulator, but it may be just as easy and just as
costly to buy a replacement. Its likely that the
regulator was old and wore down through natural
excessive use. A new electric pump is likely to
last longer, although you can expect a cheaper
model to wear out quicker than a top end one.
