Petersham's drains are old, and most of them run under houses built more than a century ago. Help Plumbing clears blocked drains Petersham terraces, flats and restaurants deal with, working from our base in Earlwood, a short drive south. We find the blockage with a camera, clear it with a jetter and show you the result. You get the price before any work starts. Call (02) 9538 7878.
Why blocked drains Petersham terraces get are hard to reach
In a narrow terrace, the sewer line often runs under the house from the bathroom at the back to the street, or out to a rear lane. The access points can be a gully in the courtyard, an old inspection opening, or a boundary trap near the front fence. Finding the right one is half the job, and it's why blocked drains Petersham homes have can take longer to reach than to clear.
Some older terraces also share a drain with the house next door, so a blockage can start on one side and show up on the other. The camera tells us which property the problem is on.

Roots, grease and old clay
Most blocked drains Petersham homes report come down to three things:
- Tree roots getting into the joints of old clay pipes.
- Grease from kitchens, which coats the pipe and catches everything that follows.
- Things that shouldn't be flushed, like wipes and sanitary products, catching in an old, rough-walled pipe.
Old clay pipe is rougher inside than modern PVC, so blockages build faster once something starts catching.
Restaurant kitchens and shop-top flats
New Canterbury Road's restaurants put a lot of grease into the drains, and the flats above and behind the shops share some of those lines. Commercial kitchens need grease traps serviced on schedule, and a blocked shared line can back up into a flat before the shop notices. For blocked drains, Petersham restaurants can book us outside trading hours, so service isn't interrupted.

How we clear blocked drains Petersham homes report
The camera goes in first, so we're not guessing. Roots, grease and silt come out with the jetter, and a mechanical auger handles anything the jetter isn't suited to. A second camera pass shows the clear pipe, and you get a written summary of the cause, which helps landlords and agents dealing with blocked drains Petersham rentals report. We don't use caustic chemicals. More on the process is on our blocked drains page.
If the pipe is cracked or broken, we explain the options, including relining by our partner relining team, before you spend anything. For a lot of blocked drains Petersham terraces keep getting, relining is the fix that lasts.
Courtyard stormwater
Terrace courtyards drain through small pits and old pipes, and they fill with leaves and silt. When one blocks, water sits against the back of the house. We clear the pit, jet the line to the lane or street, and check it with a camera. These are often the quickest blocked drains Petersham homes have.
