Your pool area may be visually appealing, but persistent drain backups can be a significant concern. In the Sutherland Shire and southern Sydney, our investigations using cutting-edge camera technology in blocked sewer or stormwater lines adjacent to pools often uncover invasive tree roots that have infiltrated the joints of ageing pipelines.
Fixing a blocked pool drain does not always necessitate lifting pavers or excavating your garden. This article delves into the causes of blockages, the methods we utilise to identify them, and how pipe relining provides an effective solution by repairing the issue from inside the pipe itself.
Which Drainage Systems Are Found Under Your Backyard Pool?
In numerous backyard pools throughout Sydney, the surrounding area is generally composed of paving, tiles, decking, retaining walls, and garden beds. Beneath this hardscape, you can typically find several drainage lines:
- The household sewer line
- Stormwater drainage systems originating from the roof, paving, and pool surroundings
- The pool backwash line
- Overflow drains and subsoil drains
It is important 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 centres on the drainage lines, which are particularly susceptible to tree root intrusion.
How Do Tree Roots Cause Blockages in Pool Drains?
Tree roots instinctively search for moisture sources, and even a minor leak at a pipe joint can attract them. Roots from trees situated several metres away can extend towards a cracked joint in older terracotta, earthenware, or PVC pipes. Once a small root breaches the pipe, it thrives in the moist environment, accumulating waste and debris, leading to a blockage.
When a drain near the pool becomes obstructed, backwash water cannot escape, potentially resulting in flooding on the pool deck. If the blockage occurs within the sewer line, it can cause showers, toilets, and floor wastes inside the house to back up.
If you are landscaping around a new pool, consider consulting our guide on suitable tree species to plant to prevent blocked drains. This guide details trees that are safer to position near pipework.
What Signs Indicate a Blocked Pool Drain or Stormwater Line?
Stay alert for the following indicators around your pool and within 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 emits gurgling sounds while the pool is being backwashed
- Water accumulates on the pavers or lawn adjacent to the pool
Each of these signs suggests a potentially blocked or damaged pipe underground, and a camera inspection will accurately identify the issue.
Why Is Excavation Around a Pool Best Avoided?
Accessing the drainage around a pool can be a daunting task that often results in damage. Typically, reaching a pipe requires lifting travertine or granite pavers, cutting through concrete slabs or retaining walls, or removing garden beds, turf, or decking. Once the pipe is repaired, restoring the paving and landscaping can involve extensive work and costs.
This is why we favour relining methods over excavation. In the highlighted case below, 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 the Sutherland Shire reached out to us regarding three significant challenges in their backyard:
- A blocked stormwater line adjacent to their in-ground pool
- Gurgling noises coming from the back garden
- Water pooling in a tiled corner
Our CCTV drain inspection uncovered significant root intrusion from a nearby tree, cracks in an old earthenware line, and multiple blocked junctions located approximately three metres beneath the pavers.
The accompanying images illustrate the situation: the first depicts the blocked pipe prior to intervention, while the second shows the same pipe after the relining process.
Instead of recommending excavation, we completed 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, with no disruption to the pavers or garden beds. The entire process was finished 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 interior surface, and allowed to cure, effectively creating a new pipe within the old one. This method 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 the surrounding pavers and garden remain undisturbed.
Our dedicated team manages every stage of the relining process, from the initial camera inspection to the final steps, without involving subcontractors. For more information on the procedure, please visit our pipe relining Sydney page.
When Is Pipe Relining Not an Option for Pool Drain Repairs?
Pipe relining is effective for pipes that are damaged but retain most of their shape. If a section has collapsed to the point that a liner cannot be inserted, that part will necessitate excavation and replacement. Similarly, if a section has sunk and lost its gradient, the liner will follow the dip, causing stagnant water, which requires reinstallation of the pipe at the correct slope.
Occasionally, our camera inspections reveal that roots have breached the Sydney Water main instead of your private pipes. In such cases, the responsibility for repairs falls to Sydney Water, and we provide the footage necessary to facilitate the reporting process.
Common Questions About Blocked Pool Drains
Can the Drain Pipes Beneath a Pool Be Relined?
Definitely. We can reline the sewer and stormwater pipes located beneath pool surrounds, provided the pipe maintains its shape. A camera inspection is conducted initially to assess the damage and confirm that a liner can be installed. If any sections have collapsed or sunk, those areas will need to be excavated and replaced.
What Methods Are Employed to Clear a Blocked Pool Drain Without Excavation?
We eliminate the blockage using high-pressure hydro jetting and root-cutting tools. Afterwards, we inspect the pipe with a CCTV camera. If the camera detects 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 the need to lift pavers, cut slabs, or disturb the garden.
What Common Factors Lead to Blocked Drains Around Pools in Sydney?
Tree roots are a primary issue we encounter around pools, particularly in older terracotta and earthenware pipes. Roots penetrate 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 is also required to 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 lies with 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 requiring sealing, and the accessibility of the entry point. We will provide you with a timeline after the camera inspection.
Book a CCTV Inspection for Your Blocked Drain Near the Pool
Our aim is to find a method for repairing the drain from within the pipe before considering excavation, and we will show you the camera footage before commencing any work.
If you observe signs of a blocked drain near your pool, arrange a CCTV inspection or contact The Blocked Drain Guys at 0418 408 333. Craig or one of our team members will explain the inspection process and what we will be examining.
