While your pool area may be visually appealing, encountering frequent drain backups can create significant frustration. In regions like the Sutherland Shire and southern Sydney, our investigations utilising advanced camera technology in blocked sewer or stormwater lines near pools often uncover invasive tree roots that infiltrate the joints of ageing pipe systems.
Addressing a blocked pool drain doesn’t always necessitate lifting pavers or excavating your garden. This article delves into the various causes of blockages, the methods we use to detect them, and how pipe relining provides an efficient internal repair solution.
What Drainage Systems Are Located Beneath Your Backyard Pool?
In many backyard pools throughout Sydney, the surrounding areas are typically enhanced with paving, tiles, decking, retaining walls, and garden beds. Beneath this hardscape, you will often find several drainage lines:
- The household sewer line
- Stormwater drainage systems that channel water from roofs, paving, and pool areas
- The pool backwash line
- Overflow drains and subsoil drains
It is crucial to understand that the pool’s filtration pipework, which connects the pump, filter, skimmer box, and return jets, operates under pressure and is distinct from the drainage systems. This discussion primarily focuses on the drainage lines, which are especially susceptible to tree root intrusion.
How Do Tree Roots Lead to Blockages in Pool Drains?
Tree roots are instinctively drawn to moisture, and even a minor leak at a pipe joint can attract them. Roots from trees located several metres away can extend towards a cracked joint in older terracotta, earthenware, or PVC pipes. Once a small root penetrates the pipe, it thrives in the damp environment, capturing waste and debris, which ultimately results in a blockage.
When a drain close to the pool becomes obstructed, backwash water cannot drain away, potentially causing flooding on the pool deck. If the blockage is situated within the sewer line, it can lead to backups in showers, toilets, and floor wastes within the home.
If you’re landscaping around a new pool, consider referring to our guide on suitable tree species to plant to avoid blocked drains. This resource offers valuable insights into trees that are safer to position near pipework.
What Are the Warning Signs of a Blocked Pool Drain or Stormwater Line?
Be vigilant for the following signs around your pool and in your home:
- Pool water drains slowly or backs up during backwashing
- The backwash line overflows
- Water bubbles up through a garden drain or grate
- A sink or shower produces gurgling sounds during pool backwashing
- Water collects on the pavers or lawn near the pool
Each of these indicators suggests a potentially blocked or damaged pipe underground, and a camera inspection will assist us in identifying the precise issue.
Why Is Avoiding Excavation Around a Pool Essential?
Accessing the drainage around a pool can be a complex task that often results in damage. Reaching a pipe typically involves lifting travertine or granite pavers, cutting through concrete slabs or retaining walls, or removing garden beds, turf, or decking. Restoring the paving and landscaping after repairs can be both extensive and costly.
For this reason, we advocate relining methods over excavation. The case highlighted below demonstrates how relining enabled us to navigate around steep stairs and an established garden without causing disruption.
Case Study: Effective Pipe Relining Solutions Near a Pool in Sutherland Shire
A homeowner in Sutherland Shire reached out to us regarding three significant issues in their backyard:
- A blocked stormwater line adjacent to their in-ground pool
- Gurgling noises coming from the back garden
- Water accumulation in a tiled corner
Our CCTV drain inspection uncovered extensive root intrusion from a nearby tree, cracks in an aged earthenware line, and multiple blocked junctions located approximately 3 metres beneath the pavers.
The images below illustrate the scenario: the first shows the obstructed pipe prior to intervention, while the second depicts the same pipe after the relining process was completed.
Instead of recommending excavation, we took the following steps:
- We cleared the line using high-pressure hydro jetting and root-cutting tools.
- We installed a resin liner throughout the damaged section to seal the cracked junctions and joints.
The stormwater line was restored to optimal flow without disturbing the pavers or garden beds. The entire process was completed in under six hours.
What Is the Pipe Relining Process Without Excavation?
We utilise a technique known as cured-in-place pipe relining. A resin-soaked liner is inserted into the damaged section of the pipe, pressed against the inner surface, and left to cure, effectively creating a new pipe within the old one. This process seals any cracks, leaking joints, and entry points exploited by tree roots. We access the pipe through an existing entry point, such as an inspection opening, ensuring that the surrounding pavers and garden remain undisturbed.
Our dedicated team manages every aspect of the relining process, from the initial camera inspection to the final stages, without relying on subcontractors. For more details about the process, please visit our pipe relining Sydney page.
When Is Pipe Relining Inappropriate for Pool Drain Repairs?
Pipe relining is most effective for pipes that are damaged but maintain most of their shape. If a section has collapsed to the extent that a liner cannot be inserted, that segment will require excavation and replacement. Similarly, if a section has sunk and lost its gradient, the liner will follow the dip, leading to stagnant water, which necessitates the reinstallation of the pipe at the correct slope.
Occasionally, our camera inspections reveal that roots have penetrated the Sydney Water main rather than your private pipes. In these situations, the responsibility for repairs lies with Sydney Water, and we provide the footage needed to facilitate the reporting process.
Common Questions Regarding Blocked Pool Drains
Can We Reline the Drain Pipes Surrounding a Pool?
Certainly. We can reline the sewer and stormwater pipes located beneath pool surrounds, provided the pipes are structurally sound. A camera inspection is conducted first to evaluate the damage and confirm that a liner can be installed. If any sections have collapsed or sunk, those areas will require excavation and replacement.
What Methods Are Used to Clear a Blocked Pool Drain Without Excavation?
We clear the blockage using high-pressure hydro jetting and root-cutting tools. Following this, we inspect the pipe with a CCTV camera. If the camera reveals cracked joints or root entry points, we can install a resin liner from within the pipe through an existing access point. This repair effectively seals the damage without requiring the lifting of pavers, cutting of slabs, or disturbing the garden.
What Are the Common Causes of Blocked Drains Around Pools in Sydney?
Tree roots are a primary cause of blockages we encounter around pools, especially in older terracotta and earthenware pipes. Roots infiltrate joints that leak water and continue to grow until they trap debris. A camera inspection will help identify the specific cause of the blockage in your drain.
Who Is Accountable for Removing Tree Roots from a Sewer Pipe in Sydney?
The property owner is responsible for their own pipes. According to Sydney Water’s guidelines regarding repair responsibilities, the owner must also clear tree roots that invade the junction at the connection point. If our camera footage shows that the roots are within the Sydney Water main, the responsibility for repairs falls to Sydney Water, and we will provide the necessary footage for reporting.
How Long Does Pipe Relining Take Near a Pool?
The relining project in Sutherland Shire mentioned in this article was completed in under six hours, which included root clearing and lining of the damaged section. The duration for your drain will depend on the length of the damaged area, the number of joints needing sealing, and the accessibility of the entry point. We will provide you with a timeline following the camera inspection.
Book a CCTV Inspection for Your Blocked Drain Near the Pool
Our aim is to determine a repair method from within the pipe before considering excavation, and we will show you the camera footage prior to commencing any work.
If you observe signs of a blocked drain near your pool, schedule a CCTV inspection or contact The Blocked Drain Guys at 0418 408 333. Craig or one of our team will explain the inspection process and what we will be looking for.
