Your pool area may look fantastic, but you could be facing persistent drain backups in the vicinity. In the Sutherland Shire and southern Sydney, our investigations using state-of-the-art camera technology in blocked sewer or stormwater lines near pools frequently reveal invasive tree roots that have breached the joints of aging pipework.
Resolving a blocked pool drain often does not require lifting pavers or digging up your garden. This article explores the various causes of blockages, the techniques we employ to identify them, and how pipe relining offers a practical solution by addressing the issue from within the pipe itself.
What Types of Drainage Systems Are Located Under Your Backyard Pool?
In numerous Sydney backyard pools, the area around them is typically paved, tiled, decked, or surrounded by retaining walls and garden beds. Beneath this hardscape, you can generally find various drainage lines:
- The household sewer line
- Stormwater drainage systems from the roof, paving, and pool area
- 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.
In What Ways Do Tree Roots Cause Blockages in Pool Drains?
Tree roots are naturally attracted to moisture sources, and even a small leak at a pipe joint can draw them in. Roots from trees positioned a few metres away can reach towards a cracked joint in older terracotta, earthenware, or PVC pipes. Once a tiny root enters, it flourishes in the damp environment inside the pipe, accumulating waste and debris, which eventually leads to a blockage.
When a drain near the pool becomes blocked, the backwash water has nowhere to go, potentially resulting in flooding on the pool deck. If the blockage is within the sewer line, it can cause showers, toilets, and floor drains inside the home to back up.
If you are landscaping around a new pool, consider checking our guide on appropriate tree species to plant to avoid blocked drains. This guide outlines trees that are safer to plant near pipework.
What Symptoms Indicate a Blocked Pool Drain or Stormwater Line?
Stay vigilant for the following signs around your pool and within your home:
- Pool water drains slowly or backs up during backwashing
- The backwash line overflows
- Water rises through a garden drain or grate
- A sink or shower produces gurgling noises while the pool is being backwashed
- Water pools on the pavers or lawn near the pool
Each of these signs suggests a possible blockage or damage within the underground pipes, and a camera inspection will help us accurately identify the problem.
Why Should You Avoid Excavation Around a Pool?
Accessing the 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 expensive.
This is why we prefer relining methods over excavation. In the example highlighted below, relining allowed us to navigate steep stairs and an established garden without causing disruption.
Case Study: Successful Pipe Relining Near a Pool in Sutherland Shire
A homeowner in the Sutherland Shire contacted us regarding three major problems in their backyard:
- A blocked stormwater line next to their in-ground pool
- Gurgling sounds from the back garden
- Water pooling in a tiled corner
Our CCTV drain inspection revealed significant 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 depict the situation: the first shows the blocked pipe before intervention, while the second illustrates the same pipe following the relining process.
Rather than 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, with no disruption to the pavers or garden beds. The entire process was completed in under six hours.
What Is the Process of Pipe Relining Without Excavation?
We employ 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 internal surface, and left to cure, effectively forming a new pipe within the old one. This technique 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 phase of the relining process, from the initial camera inspection to the final stages, without involving 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 works well for pipes that are damaged but retain most of their shape. If a section has collapsed to the extent that a liner cannot be inserted, that portion will need excavation and replacement. Likewise, if a section has sunk and lost its gradient, the liner will follow the dip, creating stagnant water, which requires reinstalling the pipe at the correct slope.
Sometimes, our camera inspections reveal that roots have penetrated 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 assist with 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 maintains its shape. A camera inspection is conducted first to assess the damage and ensure that a liner can be installed. Any sections that have collapsed or sunk will need to be excavated and replaced.
What Techniques Are Used to Resolve a Blocked Pool Drain Without Excavation?
We clear the blockage using high-pressure hydro jetting and root-cutting tools. After that, we inspect the pipe with 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 Common Issues Cause Blocked Drains Around Pools in Sydney?
Tree roots are a primary culprit we encounter around pools, particularly 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 Responsible 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 on 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 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 following the camera inspection.
Schedule 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 notice 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 looking for.
