Your pool area may appear stunning, yet you could be struggling with ongoing drain backups nearby. In the Sutherland Shire and southern Sydney, our investigations, utilising advanced camera technology in blocked sewer or stormwater lines close to pools, often uncover invasive tree roots that have intruded upon the joints of older pipes.
Resolving a blocked pool drain does not always necessitate lifting pavers or digging up your garden. This article delves into the causes of blockages, the methods we employ to identify them, and how pipe relining serves as an effective solution by repairing the issue from within the pipe.
What Drainage Systems Are Found Underneath Your Backyard Pool?
In numerous Sydney backyard pools, the surrounding area is often adorned with paving, tiles, decking, retaining walls, and garden beds. Beneath this hardscape, you typically find various drainage lines:
- Sewer line from the household
- Stormwater drainage systems from the roof, paving, and surrounding pool
- Backwash line for the pool
- Overflow drains and subsoil drains
It is crucial to understand that the pool’s filtration pipework, connecting 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 invasion.
How Do Tree Roots Create Blockages in Pool Drains?
Tree roots instinctively pursue moisture sources, and even a minor leak at a pipe joint can draw them in. Roots from trees several metres away can extend towards a damaged joint in older terracotta, earthenware, or PVC pipes. Once a small root infiltrates, it thrives in the moist conditions within the pipe, trapping waste and debris and ultimately leading to a blockage.
When a drain near the pool becomes obstructed, backwash water lacks an escape route, 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 home to back up.
If you are landscaping around a new pool, we recommend consulting our guide on appropriate tree species to plant to avoid blocked drains. This guide provides essential information on trees that are safer to plant near pipework.
What Warning Signs Suggest a Blocked Pool Drain or Stormwater Line?
Be 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 produces gurgling sounds when the pool is backwashed
- Water accumulates on the pavers or lawn adjacent to the pool
Each of these symptoms indicates a potentially blocked or damaged pipe underground, and a camera inspection will help us accurately pinpoint the issue.
Why Is Excavation Around a Pool Best Avoided?
Accessing the drainage around a pool presents a significant challenge that often leads to damage. Reaching a pipe usually involves lifting travertine or granite pavers, cutting through concrete slabs or retaining edges, or removing garden beds, turf, or decking. After the pipe has been repaired, restoring the paving and landscaping can be both extensive and costly.
This is why we prefer relining techniques over excavation. In the case highlighted below, relining enabled us to navigate steep stairs and an established garden without causing disruption.
Case Study: Effective Pipe Relining Solutions Near a Pool in the Sutherland Shire
A homeowner in the 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 pooling in a tiled corner
Our CCTV drain inspection uncovered substantial 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 depict the situation: the first shows the blocked pipe before intervention, while the second illustrates the same pipe after the relining process.
Rather than recommending excavation, we took the following steps:
- We cleared the line using high-pressure hydro jetting and root-cutting equipment.
- 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 method 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 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 untouched.
Our dedicated team oversees every stage of the relining process, from the initial camera inspection to the final stages, without subcontractors. For more details on the procedure, please visit our pipe relining Sydney page.
When Is Pipe Relining Not Appropriate for Pool Drain Repairs?
Pipe relining is suitable for pipes that are damaged but still retain most of their shape. If a section has collapsed to the point 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 reinstalling the pipe at the correct slope.
Occasionally, our camera inspections reveal that roots have infiltrated the Sydney Water main rather than your private pipes. In these instances, the responsibility for repairs falls to Sydney Water, and we provide the footage necessary to facilitate the reporting process.
Commonly Asked Questions About Blocked Pool Drains
Is It Possible to Reline the Drain Pipes Surrounding a Pool?
Certainly. We can reline the sewer and stormwater pipes located beneath pool surrounds, provided the pipe maintains its shape. 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 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. After this, we inspect the pipe using a CCTV camera. If the camera identifies cracked joints or root entry points, we can install a resin liner from inside 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 Are the Common Causes of Blocked Drains Around Pools in Sydney?
Tree roots are a primary contributor to blockages 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 must also clear tree roots that invade the junction at the connection point. If our camera footage indicates that the roots are within the Sydney Water main, the responsibility for repairs falls to Sydney Water, and we will provide the necessary footage to report it.
How Long Does Pipe Relining Take When Conducted Near a Pool?
The relining project in Sutherland Shire, discussed in this article, was completed in under six hours, including 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 following the camera inspection.
Book a CCTV Inspection for Your Blocked Drain Near the Pool
We strive to find a method for repairing the drain 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 another member of our team will explain the inspection process and what we will be looking for.
