Pressure limiting valve
Most homes have a valve at the meter that sets the pressure entering the house. When it fails, pressure drops everywhere at once.

Low Water Pressure Caboolture
Low pressure is a symptom, and the cause is usually one of a handful of things: a failing pressure limiting valve, a stop tap left half closed, a leak bleeding pressure away, scale in old pipe, or a blocked fixture. Caboolture Plumbing and Hot Water tests the pressure at several points and fixes the cause rather than guessing.

Why the pressure is low
A partly closed valve
A stop tap at the meter or inside the house left half closed after earlier work restricts flow without anyone noticing.
Corroded or scaled pipe
Older galvanised pipe narrows inside over the years until the flow is choked. Common in the older streets of Caboolture.
A hidden leak
Water escaping under the slab or in the garden takes pressure with it, often with no visible sign except the bill.
Blocked fixture or aerator
If it is one tap or one shower, scale in the aerator, the showerhead or the flow restrictor is the usual cause.
The mains supply
If the neighbours have the same problem, it is the network. Unitywater can tell you about supply work in the street.
Hot water pressure low but cold fine?
That points to the hot water system rather than the plumbing. Sediment in a storage tank, a failing tempering or relief valve, or an ageing unit that cannot deliver the flow are the usual causes, and the fix is different from a whole-house pressure problem. We check the unit when only the hot side is weak.
What we do on a pressure call
Measure
A gauge on an outside tap and at fixtures inside shows whether the problem is the whole house or one outlet.
Check the valves
The pressure limiting valve, the meter stop tap and internal isolation valves are inspected and adjusted or replaced.
Test for leaks
A meter test and pressure test rule a hidden leak in or out.
Leak detectionFix the cause
Valve replaced, fixture cleaned, leak repaired or a section of choked pipe replaced, then the pressure is measured again.
What a pressure visit includes
What a pressure visit includes
You get a measured before-and-after figure, not a shrug.
- Pressure measured at the meter and at fixtures
- Pressure limiting valve and stop taps checked
- Meter test for a hidden leak
- Cause fixed and the pressure measured again
How it works
1
Call or book online
Tell us what you have noticed: a wet patch, a bill that jumped, a meter that keeps turning. That sets the equipment we bring.
2
Locate
Pressure testing, acoustic listening and thermal imaging narrow the leak to a spot before anything is opened.
3
Price before work
The repair is priced once the leak is found, so you know the cost before a wall or a slab is touched.
4
Repair and re-test
The section is repaired, the system is pressure tested again, and you are shown that the meter has stopped moving.
Questions answered
What is normal water pressure for a house?
Pressure limiting valves in Queensland are commonly set around 500 kPa. Above that, fittings and appliances wear faster; well below it, showers feel weak. We measure yours and tell you where it sits.
Why is only the shower weak?
The showerhead or its flow restrictor is scaled up, or the mixer cartridge is worn. Both are fixed at the shower without touching the rest of the house.
Why does the pressure drop when two taps run?
The supply pipe or the valve feeding the house cannot pass enough flow. Old, narrowed pipe from the meter is the common cause in older homes.
Can high pressure be a problem too?
Yes. Pressure that is too high bangs pipes, wears washers and can fail a hot water relief valve. A pressure limiting valve fixes it.
