Water Pressure and Backflow Hampton Park

Low water pressure

Weak showers and slow-filling cisterns are common in older Hampton Park homes with galvanised pipe, where rust narrows the inside of the pipe over decades. Other causes include a partly closed or faulty stopcock, a blocked tap aerator, a failing pressure limiting valve or a leak. We test pressure at the meter and at the fixtures to find the cause, then repair or replace the pipe or valve responsible.

High pressure and water hammer

Pressure that is too high can damage tapware, hot water units and appliances and cause banging pipes. We fit pressure limiting valves at the meter and secure loose pipes to stop water hammer.

Backflow prevention

Backflow devices stop contaminated water flowing back into the drinking water supply. Properties with rainwater tanks connected to mains, irrigation systems, and many businesses need them. We install, test and repair backflow devices and lodge test reports with South East Water where required.

Pressure testing

We measure static pressure at the meter and flow at your fixtures. That shows whether the problem is the supply, your pipes or a single fitting, so you only pay to fix what is wrong.

Rainwater tanks

Tanks connected to toilets and laundries usually need a mains changeover device and backflow protection. We install and service both so the tank and mains never mix.

Water hammer

Banging pipes when a tap or washing machine valve closes quickly is called water hammer. It stresses joints and fittings. We secure loose pipes, fit arrestors near appliances and reduce pressure where it is too high.

Commercial backflow

Businesses with medical, food, chemical or irrigation equipment usually need testable backflow devices tested every year, with reports lodged with the water corporation.

Pressure limiting valves

A pressure limiting valve at the meter protects tapware and appliances and can reduce hot water relief valve dripping. We fit and set them to suit your home.

We explain the results so you know exactly what was wrong.

Hampton Park soil and pipes

Hampton Park sits on heavy grey clay over sandier ground towards Lyndhurst, and that clay swells in a wet winter and shrinks and cracks in a dry summer. The older homes west of Hallam Road were mostly connected with earthenware sewer pipe in short lengths, and every joint is a place for roots to get in once the ground moves. Galvanised steel water pipe from the same era rusts from the inside, narrowing the bore and eventually leaking. On the newer estates, PVC drains are tougher, but trenches that were not compacted properly can settle and leave dips that hold grease and paper. We use a drain camera and pressure testing to see what is actually happening rather than guessing.
