Blocked drains are not uncommon.
The majority of Sydney Metro’s stormwater and drainage infrastructure now needs to be updated or replaced, especially the decaying pre-war clay pipework. Many Sydney residents are experiencing repetitive drainage issues for any of the reasons below:
- Infiltration and damage caused by tree roots.
- Blocking caused by build up of foreign matter such as fats, oils and sanitary items
- Simply collapsing due to old age and water pressure.
The best advice we can give customers is to resolve the issue as soon as it starts because the longer you leave the problem the more costly it becomes.
How do tree roots damage drainage?
The main cause of domestic blocked drains is tree roots. The thinnest crack in your pipe is all a tree requires to infiltrate your pipe system with its hair line end roots. Getting access into your water pipe is like finding a gold mine for these roots.
Once they have discovered the source they spread thickly down the pipe to create a damn effect which will block your pipework, back up into your property all the way up to your toilet. The roots will also damage the pipe, the crack will widen with the pressure of the root growth.
How do we fix a Blockage?
Plunging is the most first way we attempt to clear a local blockage.
When this is not effective the best way to clear a blockage permanently is to feed specialised CCTV camera apparatus down the drain to identify the cause such as tree roots, a collapsed drain, or blockage caused other foreign items.
The plumber can see everything on his screen, which is linked to the CCTV. He will then provide the customer with a detailed written report and a DVD recording of his findings (please request this before CCTV service commences)
Once the blockage has been assessed we will know exactly where the blockage is located, and the most effective entry point to feed in our high pressure jetting equipment to clear the blocked drain. The jetter operates with such power that they can cut through tree roots and other debris such as food, oil, sanitary products, plants and soils.
If you are finding that your drains block up 3-6 months after they have been cleared you should need to consider investing in a long-term solution. The next step is to either replace, reline or patch the pipework.
Relining and Patching
This solution causes the least disruption to the property owner. It only requires once access point though which the repair can be completed. We offer this in house service which keeps costs down unlike other plumbing businesses who have to outsource this work to contractors.
The second option is to excavate the surface above the area where the drain keeps blocking to replace the section that needs to be repaired. This is sometimes the preferred option when the location is under soft landscaping.
