Your Local Castle Hill Plumber
The Hills is newer housing on reactive clay soil, and that soil does more damage to drainage than anything else in the district. Large homes on large blocks also mean long runs of pipe, which is where the movement shows. Around the homes, Castle Hill also has shops, offices and the business park at Norwest next door, so we work on commercial premises here as well as houses.
Reactive clay swells when wet and shrinks when dry, and it moves whatever is buried in it. On a long drainage run under a large Hills home, that movement pulls joints apart and cracks pipe over years. It is why blockages here often have nothing to do with what has gone down the drain, and why a camera inspection matters — the fault is structural, and clearing it will not keep it clear.

Common Plumbing Problems in Castle Hill
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 Castle Hill.
Soil movement cracking drainage
Reactive clay expands and contracts with the seasons and takes buried pipe with it. Joints pull apart and pipe cracks, which is a structural fault rather than a blockage — and it will recur until it is repaired properly.
Toilets that block again and again
A toilet that blocks once is usually something that went down it. A toilet that keeps blocking, or blocks along with a shower or floor waste, usually points further down the line: a cracked or separated joint in the sewer, which on a long Hills drainage run can be well away from the house. Plunging clears the symptom; a camera finds the cause.
Long drainage runs on large blocks
Bigger homes on bigger blocks mean more pipe between the house and the connection. More length means more joints, more fall to maintain, and more places for a fault to sit unnoticed.
Rainwater tanks, irrigation and backflow
Plumbed rainwater tanks, in-ground irrigation and pool top-ups are common on Hills blocks. Tank pumps and rain-to-mains switching devices wear out over time, and any of these connections can need a backflow prevention device. A testable device has to be tested every year by a certified tester, and many owners inherit one with the property without knowing it.
Stormwater and absorption on clay
Clay does not absorb well, so stormwater has to be moved rather than soaked away. Where a system was undersized or has partially blocked, water ponds on the surface instead.

Common Questions
FAQs
Do you do emergency plumbing in Castle Hill after hours?
Yes. Our phones are answered 24 hours a day, including weekends and public holidays, and we send a licensed plumber out after hours for problems that can't safely wait, such as a burst pipe, sewage coming up inside or the only toilet in the house blocked. You get a fixed price before any work starts.
My toilet is blocked. Is it the toilet or the drain?
If only the toilet is affected, the blockage is usually in the toilet or just past it. If the shower or floor waste gurgles or backs up when you flush, or the overflow gully outside is bubbling, the blockage is further down the sewer line. Stop flushing either way. In Castle Hill, a toilet that keeps blocking often points to a cracked or separated sewer joint, which a camera inspection confirms.
My drain blocks even though we are careful about what goes down it. Why?
In the Hills that usually points to soil movement cracking the pipe or pulling a joint apart, rather than anything you have put down it. A camera inspection confirms it, and shows whether the pipe can be relined or needs a section dug up and replaced.
Do you repair rainwater tank pumps in Castle Hill?
Yes. We repair and replace tank pumps and rain-to-mains switching devices, connect new tanks, and connect tanks to toilets, the laundry and garden taps in Castle Hill and the surrounding suburbs.

Yes. We test, certify, repair and install backflow prevention devices for homes and businesses in Castle Hill. Testable devices must be tested every 12 months by a certified tester, and we lodge the results with Sydney Water for you.
