Your pool area may look stunning, but frequent drain backups can be a troubling issue. In the Sutherland Shire and southern Sydney, our investigations using advanced camera technology on blocked sewer or stormwater lines near pools often reveal invasive tree roots that have penetrated the joints of older pipework.
Resolving a blocked pool drain doesn’t always require lifting pavers or excavating your garden. This article explores the causes of blockages, the techniques we employ to identify them, and how pipe relining offers an effective solution by repairing the issue from inside the pipe.
What Types of Drainage Systems Are Located Beneath Your Backyard Pool?
In many Sydney backyard pools, the surrounding area is typically covered with paving, tiles, decking, retaining walls, and garden beds. Beneath this hardscape, you will commonly find several drainage lines:
- The household sewer line
- Stormwater drainage systems 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 discussion focuses on the drainage lines, which are particularly vulnerable to tree root intrusion.
How Do Tree Roots Cause Blockages in Pool Drains?
Tree roots naturally seek out sources of moisture, and even a small leak at a pipe joint can attract them. Roots from trees several metres away can reach towards a fractured joint in older terracotta, earthenware, or PVC pipes. Once a minor root establishes itself inside, it flourishes in the moist environment, capturing waste and debris, which ultimately leads to a blockage.
When a drain adjacent to the pool becomes blocked, backwash water has no place to go, which can result in flooding on the pool deck. If the blockage is within the sewer line, it can cause showers, toilets, and floor drains inside the house to back up.
If you are landscaping around a new pool, consider checking our guide on suitable tree species to plant to prevent blocked drains. This guide provides insights into trees that are safer to position near pipework.
What Signs Indicate a Blocked Pool Drain or Stormwater Line?
Stay vigilant for these indicators 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 noises when the pool is being backwashed
- Water pools 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 locate the issue.
Why Is It Better to Avoid Excavation Around a Pool?
Accessing drainage around a pool can be a complicated task 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. Once the pipe is repaired, restoring the paving and landscaping can be extensive and costly.
This is why we prefer relining methods over excavation. In the example 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 about three major issues in their backyard:
- A blocked stormwater line next to their in-ground pool
- Gurgling sounds 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 prior to intervention, while the second depicts the same pipe after the relining process.
Instead of suggesting excavation, we executed 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. 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-impregnated liner is inserted into the damaged section of the pipe, pressed against the inner surface, and allowed to cure, effectively forming 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 stages, without involving subcontractors. For more information on the procedure, please visit our pipe relining Sydney page.
When Is Pipe Relining Not Suitable for Pool Drain Repairs?
Pipe relining is appropriate for pipes that are damaged but retain most of their shape. If a section has collapsed to such an extent that a liner cannot be inserted, that part will need excavation and replacement. Similarly, 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 breached the Sydney Water main rather than your private pipes. In these cases, the responsibility for repairs lies with Sydney Water, and we provide the necessary footage to assist with 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, provided the pipe maintains its shape. A camera inspection is conducted initially 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 Utilised to Resolve a Blocked Pool Drain Without Excavation?
We clear the blockage using high-pressure hydro jetting and root-cutting tools. After this, we inspect the pipe with a CCTV camera. If the camera identifies cracked joints or root entry points, we can insert 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 Causes Contribute to 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 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 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 rests 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
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 before starting 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.
