Your pool area might look fantastic, but frequent drain backups can be a real hassle. In the Sutherland Shire and southern Sydney, our investigations using advanced camera technology in blocked sewer or stormwater lines adjacent to pools frequently reveal invasive tree roots that have penetrated the joints of older pipe systems.
Resolving a blocked pool drain doesn’t always require lifting pavers or digging up your garden. This article explores the causes of blockages, the techniques we use to diagnose them, and how pipe relining offers a powerful solution by addressing the issue from inside the pipe.
What Types of Drainage Systems Exist Beneath Your Backyard Pool?
In many backyard pools across Sydney, the surrounding area is typically covered with paving, tiles, decking, retaining walls, and garden beds. Beneath this hardscape, several drainage lines are usually present:
- The household sewer line
- Stormwater drainage systems that collect water from the roof, paving, and pool area
- The pool backwash line
- Overflow drains and subsoil drains
It’s important 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 article focuses on the drainage lines, which are particularly vulnerable to tree root intrusion.
How 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 lure them in. Roots from trees several metres away can reach towards a damaged joint in older terracotta, earthenware, or PVC pipes. Once a small root enters, it flourishes in the damp environment within the pipe, accumulating waste and debris, which ultimately results in a blockage.
When a drain near the pool becomes blocked, backwash water has nowhere to go, which can lead to flooding on the pool deck. If the blockage is within the sewer line, it may cause showers, toilets, and floor wastes inside the home to back up.
If you are landscaping around a new pool, consider consulting our guide on suitable tree species to plant to avoid blocked drains. This guide includes information on trees that are safer to position near pipework.
What Signs Indicate a Blocked Pool Drain or Stormwater Line?
Be vigilant for the following signs 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 makes gurgling sounds when the pool is backwashed
- Water collects on the pavers or lawn next to the pool
Each of these symptoms points to a potentially blocked or damaged pipe underground, and a camera inspection will help us accurately pinpoint the problem.
Why Should You Avoid Excavation Around a Pool?
Accessing drainage around a pool can be a challenging endeavour that often results in damage. Reaching a pipe generally requires 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 both extensive and costly.
This is why we prefer relining methods over excavation. In the case highlighted below, relining allowed us to work around steep stairs and an established garden without causing disruption.
Case Study: Successful Pipe Relining Solutions Near a Pool in Sutherland Shire
A homeowner in the Sutherland Shire contacted us about three major issues 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 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 images below illustrate the situation: the first shows the blocked pipe prior to intervention, while the second depicts the same pipe after the relining process.
Instead of suggesting 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 disturbance to the pavers or garden beds. The entire process was completed in under six hours.
What Is the Pipe Relining Process Without Excavation?
We use a method known as cured-in-place pipe relining. A resin-soaked liner is introduced into the damaged section of the pipe, pressed against the internal 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 undisturbed.
Our dedicated team manages every phase of the relining process, from the initial camera inspection to the final stages, without subcontractors. For further 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 their shape. If a section has collapsed to the extent that a liner cannot be inserted, that segment will require excavation and replacement. if a section has sunk and lost its gradient, the liner will follow the dip, leading to stagnant water, which necessitates reinstallation of 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 such cases, repair responsibility lies with Sydney Water, and we provide the footage necessary for reporting.
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. If any sections have collapsed or sunk, those areas will need to be excavated and replaced.
What Techniques Are Used to Resolve a Blocked Pool Drain Without Excavation?
We eliminate the blockage using high-pressure hydro jetting and root-cutting tools. Following this, 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 within the pipe through an existing access point. This repair effectively seals the damage without lifting pavers, cutting slabs, or disturbing the garden.
What Common Factors Contribute to Blocked Drains Around Pools in Sydney?
Tree roots are a leading 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 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 needing 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 aim to identify a method for repairing the drain from within the pipe before considering excavation, and we will share the camera footage with you before commencing any work.
If you notice signs of a blocked drain near your pool, book 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.
