Your pool area may look beautiful, but persistent drain backups nearby could be causing you frustration. In the Sutherland Shire and southern Sydney, our investigations with camera technology in blocked sewer or stormwater lines adjacent to pools frequently reveal invasive tree roots that have penetrated the joints of older pipework.
Resolving a blocked pool drain does not always mean you have to lift pavers or excavate your garden. This article explores the causes of blockages, the techniques we use to identify them, and how pipe relining offers a reliable solution by repairing the issue from within the pipe itself.
What Types of Drainage Systems Exist Beneath Your Backyard Pool?
In numerous Sydney backyard pools, the surrounding area is often covered with paving, tiles, decking, retaining walls, and garden beds. Beneath this hardscape, you will typically discover several drainage lines:
- The sewer line from 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 especially vulnerable to tree root intrusion.
How Do Tree Roots Cause Blockages in Pool Drains?
Tree roots are instinctively attracted to moisture sources, and even a slight leak at a pipe joint can entice them. Roots from trees positioned several metres away can extend towards a fractured joint in older terracotta, earthenware, or PVC pipes. Once a small root infiltrates a pipe, it flourishes in the moist conditions, trapping waste and debris, ultimately leading to a blockage.
When a drain near the pool becomes clogged, the backwash water has nowhere to go, potentially causing flooding on the pool deck. If the blockage is within the sewer line, it may result in showers, toilets, and floor wastes inside the house backing up.
If you are landscaping around a new pool, consider consulting our guide on suitable tree species to plant to prevent blocked drains. This resource provides recommendations on trees that are safer to position near pipework.
What Signs Indicate a Blocked Pool Drain or Stormwater Line?
Keep an eye out 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 when the pool is being backwashed
- Water accumulates on the pavers or lawn adjacent to the pool
Each of these symptoms signifies a potentially blocked or damaged pipe underground, and a camera inspection will help us accurately pinpoint the issue.
Why Should You Avoid Excavation Around a Pool?
Accessing the drainage around a pool can be challenging and 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 repairing the pipe, restoring the paving and landscaping can be extensive and expensive.
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 disruption.
Case Study: Successful Pipe Relining Solutions Near a Pool in Sutherland Shire
A homeowner in the Sutherland Shire contacted us regarding three significant issues in their backyard:
- A blocked stormwater line adjacent to their in-ground pool
- Gurgling noises emanating from the back garden
- Water pooling in a tiled corner
Our CCTV drain inspection revealed substantial 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 provided illustrate the situation: the first shows the blocked pipe before intervention, while the second depicts the same pipe following the relining process.
Instead of 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 successfully restored to its optimal flow without disturbing the pavers or garden beds. The entire process was completed in under six hours.
What Is the Process for Pipe Relining Without Excavation?
We employ a technique called 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 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 that the surrounding pavers and garden remain undisturbed.
Our dedicated team oversees 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 a Suitable Option 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 a point where a liner cannot be inserted, that segment will need excavation and replacement. Likewise, if a section has sunk and lost its gradient, the liner will follow the dip, causing stagnant water, which requires 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 such cases, the responsibility for repairs falls to Sydney Water, and we provide the footage necessary to assist in 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, as long as the pipe retains its shape. A camera inspection is conducted 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 Resolve 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 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 Contribute to Blocked Drains Around Pools in Sydney?
Tree roots are a primary cause 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 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 on repair responsibilities, the owner must also remove 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 earlier, 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 strive to determine a method for repairing the drain from within the pipe before considering excavation, and we will share the camera footage before 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.
