Plumber Merrylands

Brickmaking clay, late sewer connections and new towers across Merrylands, Guildford and Holroyd.

Our guarantee: 12 months on our workmanship, in writing. What it covers

Merrylands is named after the English home of Arthur Todd Holroyd, who bought land here in 1855. The railway station opened in 1878 and subdivision followed, but the district was as much industry as housing for a long time: around 1929 there were 14 brick and tile works in the Merrylands area, and Stockland Merrylands stands on the site of one of them. The Housing Commission built here after the Second World War, and since the 2010s high-rise apartments have gone up in the town centre. The suburb is in Cumberland Council.

Two local facts shape the plumbing. The first is the ground. The clay that kept all those brickworks busy is the same clay under Merrylands homes, and clay soils of this kind move as they wet and dry. The second is timing. Most of the old Holroyd municipality was not sewered until after the Second World War, so many older houses were built first and connected later, with drainage fitted around them rather than planned with them. The town centre is a different job again. Towers of more than a dozen storeys now rise above the older shops, and A'Becketts Creek, which starts near the shopping centre, has been channelled and piped underground there.

$0 call-out fee — available 24/7, 365 days a year across Merrylands and nearby suburbs.

Every part of Sydney has its own plumbing character, shaped by the age of the housing, the ground it sits on, and the weather it takes. Here is what we are called out for most often around Merrylands.

Where a house is older than the local sewer, the line to the main was added later and followed whatever route suited at the time. Those runs can be long, can pass under later additions, and are now decades old in their own right. A camera inspection maps the route before anyone starts digging.

In a long dry spell the clay under Merrylands shrinks, and it swells again when the rain returns. Rigid pipe laid in it can crack or pull apart at the joints over the years, and roots move into the gaps. When a line keeps blocking at the same point, relining that length is usually the lasting fix.

A stain on a ceiling in a new apartment building usually has its source in a unit above, such as a shower seal, a flexible hose or a fitting hidden behind a vanity. Tracing it before anything is cut open keeps the repair, and the bill, with the right owner.

Stormwater Drainage ·

The problem

The old stormwater line around the perimeter of the house was cracked and broken.

What we did

We dug the trenches by machine and laid 50 m of new 100 mm stormwater line around the house, connected the downpipes, and installed a new pit and a new line out to the street.

Common Questions

Street drainage belongs to Cumberland Council, which says its pipes are designed for frequent minor storms while bigger storms follow overland flow paths. Council is studying flooding across the Duck River, Duck Creek and A'Becketts Creek catchments. What we can fix is the drainage on your own property, so it is not adding to the problem.

It can. The line may take an unusual path, run under a later extension or join the house somewhere unexpected. Camera footage traces its path and shows its condition.

Often, yes. Relining works from existing access points, so a pipe under a sunroom or slab can usually be repaired without breaking through the floor. The camera footage shows whether the pipe is suitable.
