Your pool area may look beautiful, but frequent drain backups can be a frustrating issue. In the Sutherland Shire and southern Sydney, our investigations with advanced camera technology in blocked sewer or stormwater lines near pools frequently reveal invasive tree roots that penetrate the joints of older pipes.
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 identify them, and how pipe relining offers a powerful solution by mending the issue from within the pipe itself.
What Drainage Systems Are Commonly Found Beneath Your Backyard Pool?
In many backyard pools across Sydney, the surrounding area is typically paved, tiled, decked, or bordered by retaining walls and garden beds. Beneath this hardscape, you can usually find several drainage lines:
- The sewer line connected to the household
- Stormwater drainage systems that collect runoff from the roof, paving, and pool area
- The pool backwash line
- Overflow drains and subsoil drains
It’s essential to differentiate between the pool’s filtration pipework, which connects the pump, filter, skimmer box, and return jets and operates under pressure, and the drainage systems. This discussion focuses on the drainage lines, which are particularly vulnerable to tree root invasion.
How Do Tree Roots Cause Blockages in Pool Drains?
Tree roots are instinctively attracted to moisture sources, and even a tiny leak at a pipe joint can entice them. Roots from trees located several metres away can stretch towards a cracked joint in older terracotta, earthenware, or PVC pipes. Once a small root infiltrates the pipe, it flourishes in the damp environment, capturing waste and debris, which ultimately results in a blockage.
When a drain near the pool gets blocked, the backwash water has nowhere to go, often leading to flooding on the pool deck. If the blockage is within the sewer line, it can cause showers, toilets, and floor wastes inside the home to back up.
If you are landscaping around a new pool, we recommend consulting our guide on suitable tree species to plant in order to prevent blocked drains. This guide details trees that are safer to plant near pipework.
What Signs Indicate a Blocked Pool Drain or Stormwater Line?
Be vigilant for these signs 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 indicates a potentially blocked or damaged pipe underground, and a camera inspection will help us accurately identify the problem.
Why Is Excavation Around a Pool Not the Best Option?
Accessing drainage around a pool can be a challenging task that often leads to 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, reinstating the paving and landscaping can be extensive and costly.
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 major concerns 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 significant root intrusion from a nearby tree, cracks in an old earthenware line, and several blocked junctions located approximately 3 metres beneath the pavers.
The accompanying images illustrate the situation: the first shows the blocked pipe before our 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 Process for Pipe Relining Without Excavation?
We employ a technique known as cured-in-place pipe relining. A resin-soaked liner is inserted into the damaged section of the pipe, pressed against the inner surface, and left to cure, effectively forming a new pipe within the old one. This method seals any cracks, leaking joints, and entry points that tree roots may exploit. 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 each stage of the relining process, from the initial camera inspection to the final stages, without involving subcontractors. For more details on the process, 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 still retain most of their shape. If a section has collapsed to a point where a liner cannot be inserted, that segment will require excavation and replacement. Likewise, if a section has sunk and lost its gradient, the liner will follow the dip, resulting in stagnant water, which necessitates reinstalling the pipe at the correct slope.
Sometimes, our camera inspections reveal that roots have penetrated the Sydney Water main rather than your private pipes. In these cases, the responsibility for repairs lies with Sydney Water, and we provide the footage necessary to facilitate 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 maintains its shape. A camera inspection is conducted first to assess the damage and ensure that a liner can be installed. If any sections are collapsed or sunk, those areas will need to be excavated and replaced.
What Techniques Are Utilised to Unblock a Pool Drain Without Excavation?
We clear blockages using high-pressure hydro jetting and root-cutting tools. After this, we inspect the pipe with a CCTV camera. If the camera reveals 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 needing to lift pavers, cut slabs, or disturb the garden.
What Common Issues Cause Blocked Drains Around Pools in Sydney?
Tree roots are a leading cause of blockages we encounter around pools, particularly 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 Accountable for Removing Tree Roots from a Sewer Pipe in Sydney?
Property owners are 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 discussed 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 after the camera inspection.
Schedule 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 before commencing any work.
If you notice signs of a blocked drain near your pool, schedule 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 searching for.
