Your pool area can look beautiful, but you might be facing issues with regular drain backups nearby. In the Sutherland Shire and southern Sydney, our investigations using advanced camera technology in blocked sewer or stormwater lines near pools frequently reveal invasive tree roots that have penetrated the joints of older pipe systems.
Resolving a blocked pool drain does not always require lifting pavers or digging up your garden. This article explores the various causes of blockages, the methods we employ to identify them, and how pipe relining offers an efficient solution by repairing the problem from within the pipe itself.
What Types of Drainage Systems Are Located Below Your Backyard Pool?
In many backyard pools across Sydney, the surrounding area is often adorned with paving, tiles, decking, retaining walls, and garden beds. Beneath this hard surface, you will typically discover several drainage lines:
- The sewer line from the home
- Stormwater drainage systems from the roof, paving, and pool vicinity
- The pool backwash line
- Overflow drains and subsoil drains
It is 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 are naturally attracted to moisture sources, and even a small leak at a pipe joint can draw them in. Roots from trees situated several metres away can reach towards a cracked joint in older terracotta, earthenware, or PVC pipes. Once a small root enters, it thrives in the moist environment within the pipe, collecting waste and debris, which ultimately leads to a blockage.
When a drain near the pool becomes blocked, the backwash water has nowhere to go, potentially resulting in flooding on the pool deck. If the blockage occurs 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, consider consulting our guide on suitable tree species to plant to avoid blocked drains. This guide details trees that are safer to position near pipework.
What Symptoms 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 when the pool is being backwashed
- Water collects on the pavers or lawn next to the pool
Each of these indicators suggests a potentially blocked or damaged pipe underground, and a camera inspection will help us accurately identify the issue.
Why Is It Better to Avoid Excavation Around a Pool?
Gaining access to the drainage around a pool can be a challenging task that often results in damage. Reaching a pipe usually requires lifting travertine or granite pavers, cutting through concrete slabs or retaining edges, or removing garden beds, turf, or decking. Once the pipe is repaired, 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 work around steep stairs and an established garden without causing any disruption.
Case Study: Successful Pipe Relining Solutions Near a Pool in Sutherland Shire
A homeowner in the Sutherland Shire contacted us about three significant problems in their backyard:
- A blocked stormwater line next 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 around 3 metres beneath the pavers.
The images accompanying this section showcase the situation: the first illustrates the blocked pipe prior to intervention, while the second shows the same pipe after the relining process.
Instead of suggesting excavation, we performed the following steps:
- We cleared the line with 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 function, 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 technique known as cured-in-place pipe relining. A resin-soaked liner is inserted into the damaged section of the pipe, pressed against the interior surface, and left to cure, creating a new pipe inside 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 manages every aspect of the relining process, from the initial camera inspection to the final stages, without using subcontractors. For more details on the procedure, please visit our pipe relining Sydney page.
When Is Pipe Relining Not a Suitable Solution for Pool Drain Repairs?
Pipe relining is ideal for pipes that are damaged but still retain most of their shape. If a segment has collapsed to the extent that a liner cannot be inserted, that portion 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 requires the reinstallation of the pipe at the correct slope.
Sometimes, 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 footage necessary 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, as long as the pipe retains its shape. A camera inspection is conducted initially to assess the damage and confirm that a liner can be installed. Any sections that have collapsed or sunk will need to be excavated and replaced.
What Techniques Are Employed to Fix 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 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 predominant cause of blockages we encounter around pools, especially in older terracotta and earthenware pipes. Roots invade 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 indicates that the roots are within the Sydney Water main, the responsibility for repairs lies with Sydney Water, and we will provide the necessary footage for reporting.
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, including root clearing and lining of the affected 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 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.
