Your pool area may appear beautiful, but recurrent drain backups nearby can be a real hassle. In the Sutherland Shire and southern Sydney, our investigations using state-of-the-art camera technology in blocked sewer or stormwater lines adjacent to pools often uncover invasive tree roots that have infiltrated the joints of older pipe systems.
Fixing a blocked pool drain doesn’t always necessitate lifting pavers or digging up your garden. This article delves into the typical causes of blockages, the methods we employ to identify them, and how pipe relining provides an effective solution by addressing the issue internally.
What Drainage Systems Are Installed Beneath Your Backyard Pool?
In many backyard pools across Sydney, the surrounding area typically comprises paving, tiles, decking, retaining walls, and garden beds. Underneath this hardscape, multiple drainage lines are usually present:
- The sewer line from the household
- Stormwater drainage systems that originate from the roof, paving, and pool surroundings
- The pool backwash line
- Overflow drains and subsoil drains
It’s crucial to understand that the pool’s filtration pipework, which connects the pump, filter, skimmer box, and return jets, operates under pressure and is distinct from the drainage systems. This article focuses on the drainage lines, known to be especially vulnerable to tree root invasion.
How Do Tree Roots Lead to Blockages in Pool Drains?
Tree roots naturally pursue 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 compromised joint in older terracotta, earthenware, or PVC pipes. Once a tiny root enters, it thrives in the moist environment within the pipe, capturing waste and debris, resulting in a blockage.
When a drain near the pool becomes blocked, the backwash water has nowhere to go, potentially leading to flooding on the pool deck. Should the blockage occur within the sewer line, it can cause showers, toilets, and floor wastes inside your home to back up.
If you are landscaping around a new pool, consider consulting our guide on suitable tree species to plant to prevent blocked drains. This guide offers insights on trees that are safer to position near pipework.
What Symptoms Indicate a Blocked Pool Drain or Stormwater Line?
Keep an eye out 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 rises through a garden drain or grate
- A sink or shower produces gurgling sounds during the pool backwash
- Water accumulates on the pavers or lawn next to the pool
These signs suggest a potentially blocked or damaged pipe underground, and a camera inspection will help us accurately identify the problem.
Why Is Excavation Around a Pool Best Avoided?
Gaining access to the drainage around a pool can be a complicated task that often results in damage. Reaching a pipe typically 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 both extensive and costly.
For this reason, we favour relining methods over excavation. The case highlighted below demonstrates how relining allowed us to navigate around steep stairs and an established garden without causing disruption.
Case Study: Effective Pipe Relining Solutions Near a Pool in Sutherland Shire
A homeowner in the Sutherland Shire reached out to us regarding three significant issues in their backyard:
- A blocked stormwater line beside their in-ground pool
- Gurgling noises coming from the back garden
- Water pooling in a tiled corner
Our CCTV drain inspection uncovered extensive root intrusion from a nearby tree, cracks in an old earthenware line, and multiple blocked junctions located about 3 metres beneath the pavers.
The images provided 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 recommending excavation, we undertook 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. This entire process was completed in less than six hours.
What Steps Are Involved in Pipe Relining Without Excavation?
We utilise 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 forming a new pipe within the existing 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 are left undisturbed.
Our dedicated team oversees every stage of the relining process, from the initial camera inspection to the final steps, without subcontractors. For further information about the procedure, please visit our pipe relining Sydney page.
When Is Pipe Relining Inappropriate for Pool Drain Repairs?
Pipe relining is effective for pipes that are damaged yet retain most of their shape. If a section has collapsed to the extent 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, resulting in stagnant water, which necessitates the 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 these cases, the responsibility for repairs falls to Sydney Water, and we provide the footage necessary to facilitate the reporting process.
Common Inquiries Regarding 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. An initial camera inspection is performed to assess the damage and confirm that a liner can be installed. Any collapsed or sunken sections will need to be excavated and replaced.
What Techniques Are Employed to Clear a Blocked Pool Drain Without Excavation?
We clear blockages using high-pressure hydro jetting and root-cutting tools. Following 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, eliminating the need to lift pavers, cut slabs, or disturb the garden.
What Are the Typical Causes of Blocked Drains Around Pools in Sydney?
Tree roots are a primary cause 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 Responsible for Removing Tree Roots from a Sewer Pipe in Sydney?
The property owner is accountable for their own pipes. According to Sydney Water’s guidelines regarding repair responsibilities, the owner must also address 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 facilitate the report.
How Long Does Pipe Relining Take Near a Pool?
The relining project in Sutherland Shire referenced 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 needing 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 aim 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, 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.
