Your pool area may look impressive, but you could be facing ongoing issues with drain backups nearby. In the Sutherland Shire and southern Sydney, our investigations often reveal invasive tree roots infiltrating the joints of older sewer or stormwater pipes adjacent to pools. We use advanced camera technology to identify these problems effectively.
Resolving a blocked pool drain doesn’t always require lifting pavers or digging up your garden. This article explores the common causes of blockages, the techniques we employ for identification, and how pipe relining offers a practical solution by repairing the issue internally.
What Types of Drainage Systems Are Typically Found Beneath Your Backyard Pool?
In many Sydney backyard pools, the areas surrounding them are often covered with paving, tiles, decking, retaining walls, and garden beds. Beneath this hardscape, you will commonly find various drainage lines:
- The household sewer line
- Stormwater drainage systems that channel water from the roof, paving, and pool surroundings
- The pool backwash line
- Overflow drains and subsoil drainage systems
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 discussion focuses on the drainage lines, which are particularly vulnerable to tree root invasion.
What Role Do Tree Roots Play in Causing Blockages in Pool Drains?
Tree roots naturally seek out moisture, and even a small leak at a pipe joint can attract them. Roots from trees positioned several metres away can extend toward a cracked joint in older terracotta, earthenware, or PVC pipes. Once a small root gains access, it thrives in the moist environment within the pipe, capturing waste and debris, which ultimately leads to a blockage.
When a drain near the pool becomes blocked, the backwash water has nowhere to go, which can result in flooding on the pool deck. If the blockage is within the sewer line, it can cause sinks, toilets, and floor wastes inside the house to back up.
If you’re landscaping around a new pool, consider consulting our guide on suitable tree species to plant in order to avoid blocked drains. This guide outlines trees that are safer to plant near pipework.
What Signs Indicate a Blocked Pool Drain or Stormwater Line?
Stay vigilant for the following signs around your pool and within your home:
- The 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 while the pool is being backwashed
- Water accumulates on the pavers or lawn adjacent to the pool
Each of these indicators suggests a potentially blocked or damaged underground pipe, and a camera inspection will help us accurately pinpoint the issue.
Why Is It Best to Avoid Excavation Around a Pool?
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 both extensive and costly.
This is why we prefer relining methods over excavation. In the case shown 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 about three significant issues in their backyard:
- A blocked stormwater line adjacent 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 three 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 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, with no disruption to 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 method known as cured-in-place pipe relining. A resin-soaked liner is introduced into the damaged section of the pipe, pressed against the inner surface, and left 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 stage of the relining process, from the initial camera inspection to the final steps, without 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 effective 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 part will require excavation and replacement. Similarly, 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, the responsibility for repairs lies with Sydney Water, and we provide the necessary footage to facilitate the reporting process.
Frequently Asked Questions About Blocked Pool Drains
Is It Possible to Reline the Drain Pipes Surrounding a Pool?
Absolutely. We can reline the sewer and stormwater pipes located beneath pool surrounds, provided the pipe maintains its shape. A camera inspection is conducted initially to assess the damage and verify 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 the need to lift pavers, cut slabs, or disturb the garden.
What Are the Common Causes of Blocked Drains Around Pools in Sydney?
Tree roots are a primary cause we encounter around pools, especially in older terracotta and earthenware pipes. Roots penetrate leaking joints 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 Liable 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 manage 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 falls to 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
Our goal is 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 starting 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.
