Low pressure causes
- rusted galvanised pipe narrowing inside
- a hidden leak on the service pipe
- a partly closed or faulty stopcock
- a blocked pressure limiting valve or tap aerator
- a faulty tempering valve if only the hot water is weak
High pressure signs
- pipes banging when taps close
- taps and cistern valves wearing out quickly
- a hot water relief valve that keeps dripping
- flexible hoses failing
Fixes
For low pressure, we find the restriction and replace pipe or valves. For high pressure, a pressure limiting valve after the meter protects the whole house.
Water hammer
Loose pipes under the floor make banging worse. Securing them and fitting a limiting valve or arrestor usually stops it.
Quick check
Unscrew tap aerators and shower heads and clean out grit before calling. It sometimes fixes the problem.
Testing
We test pressure at the meter and at fixtures to find the cause and recommend the simplest fix.
Pressure in units
In older unit blocks, a shared supply pipe can be undersized for the number of units, so pressure drops when neighbours use water. We can check and advise on upgrades with the owners corporation.
Hot versus cold
If only the hot side is weak, the tempering valve or hot water unit is likely the cause.
Mains pressure varies
Pressure from the mains changes during the day. It is often highest at night, when demand is low, which is when pipes and fittings are under the most stress. A pressure limiting valve evens this out.
When to call
Call us if pressure changes suddenly, if a tap or shower drops off, or if pipes bang loudly.
Testing at home
A simple pressure gauge on a garden tap gives a rough reading. Very high or very low readings are worth a professional check. Call us to book a pressure test.
Noble Park pipes at a glance
Most of Noble Park was built between the late 1940s and the 1970s, so original houses usually have clay sewer pipe, galvanised or early copper water pipe and gas hot water outside the laundry. Newer townhouses on subdivided blocks have PVC drains, plastic or copper water pipe and continuous-flow or heat pump hot water. We use cameras, locators, pressure tests and leak detection gear to see what is going on before anyone digs or cuts a wall.
