Your pool area may look incredible, but you could be facing persistent drain backups nearby. In the Sutherland Shire and southern Sydney, our investigations utilising camera technology in blocked sewer or stormwater lines adjacent to pools frequently reveal invasive tree roots that have breached the joints of older pipework.
Resolving a blocked pool drain doesn’t always require removing pavers or digging up your garden. This article explores the underlying causes of blockages, the techniques we use to identify them, and how pipe relining offers an effective solution by repairing the issue from within the pipe itself.
What Types of Drainage Systems Are Located Beneath Your Backyard Pool?
In many Sydney backyard pools, the surrounding area is typically covered with paving, tiles, decking, retaining walls, and garden beds. Beneath this hardscape, you will usually find several drainage lines:
- The sewer line connected to the household
- Stormwater drainage systems originating from the roof, paving, and pool surroundings
- The pool backwash line
- Overflow drains and subsoil drains
It is essential to note that the pool’s filtration pipework, which connects the pump, filter, skimmer box, and return jets, operates under pressure and is separate from the drainage systems. This discussion focuses on the drainage lines, which are particularly vulnerable to tree root intrusion.
How Do Tree Roots Cause Blockages in Pool Drains?
Tree roots naturally seek out sources of 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 finds its way inside, it thrives in the moist environment within the pipe, collecting waste and debris, which ultimately leads to a blockage.
When a drain near the pool becomes blocked, the backwash water has no outlet, potentially causing flooding on the pool deck. If the blockage is within the sewer line, it can lead to backflows in showers, toilets, and floor wastes inside the house.
If you’re landscaping around a new pool, consider consulting our guide on suitable tree species to plant to prevent blocked drains. This guide provides insights on trees that are safer to position near pipework.
What Signs Indicate a Blocked Pool Drain or Stormwater Line?
Be vigilant for the following indicators around your pool and inside 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 during pool backwashing
- Water pools on the pavers or lawn next to the pool
Each of these signs signifies a potentially blocked or damaged pipe underground. A camera inspection will help us accurately locate the issue.
Why Should Excavation Around a Pool Be Avoided?
Gaining access to drainage around a pool can be a challenging 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. After repairing the pipe, restoring the paving and landscaping can be extensive and costly.
This is why we prefer relining methods over excavation. In the case highlighted below, relining allowed us to navigate around steep stairs and an established garden without causing any disruption.
Case Study: Successful Pipe Relining Solutions Near a Pool in Sutherland Shire
A homeowner in the Sutherland Shire contacted us regarding three significant concerns in their backyard:
- A blocked stormwater line next to their in-ground pool
- Gurgling sounds coming from the back garden
- Water pooling in a tiled corner
Our CCTV drain inspection revealed extensive root intrusion from a nearby tree, cracks in an old earthenware line, and multiple blocked junctions located approximately 3 metres beneath the pavers.
The accompanying images illustrate the situation: the first shows the blocked pipe before intervention, while the second depicts the same pipe after the relining process.
Instead of suggesting excavation, we carried out 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.
How Does Pipe Relining Work Without Excavation?
We employ a technique known as cured-in-place pipe relining. A resin-soaked liner is introduced into the damaged section of the pipe, pressed against the interior surface, and left to cure, effectively forming 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 supervises every phase of the relining process, from the initial camera inspection through to the final stages, without the involvement of subcontractors. For more details on the procedure, please visit our pipe relining Sydney page.
When Is Pipe Relining Not Suitable for Pool Drain Repairs?
Pipe relining is ideal 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 segment will require excavation and replacement. Likewise, if a section has sunk and lost its gradient, the liner will follow the dip, resulting in 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 instead of your private pipes. In these situations, the responsibility for repairs falls to Sydney Water, and we provide the footage necessary to facilitate the reporting process.
Frequently Asked Questions About Blocked Pool Drains
Can the Drain Pipes Surrounding a Pool Be Relined?
Absolutely. We can reline the sewer and stormwater pipes located beneath pool surrounds, provided the pipe retains its shape. A camera inspection is performed first 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 Techniques Are Utilised to Fix a Blocked Pool Drain Without Excavation?
We remove the blockage using high-pressure hydro jetting and root-cutting tools. Afterward, 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 Reasons Lead to Blocked Drains Around Pools in Sydney?
Tree roots are a primary cause 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 reason for 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 remove 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 lies with Sydney Water, and we will provide the necessary footage to report it.
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 following the camera inspection.
Schedule a CCTV Inspection for Your Blocked Drain Near the Pool
We strive to determine 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 notice 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 members will explain the inspection process and what we will be looking for.
