Tree Roots Blocking Pipes? Discover Effective Pool Solutions

Your pool area may be aesthetically pleasing, yet you could be grappling with ongoing drainage challenges nearby. In the Sutherland Shire and southern Sydney, our investigations employing camera technology in obstructed sewer or stormwater lines adjacent to pools often uncover invasive tree roots that have infiltrated the joints of ageing pipework.

Addressing a blocked pool drain does not invariably necessitate lifting pavers or excavating your garden. This article delves into the factors contributing to blockages, the methodologies we utilise for detection, and how pipe relining presents a viable solution by tackling the issue from within the pipe itself.

What Drainage Systems Exist Underneath Your Backyard Pool?

In numerous Sydney backyard pools, the surrounding space is typically adorned with paving, tiles, decking, retaining walls, and garden beds. Beneath this hardscape, several drainage lines are usually present:

• The sewer line from the household
• Stormwater drainage systems originating from the roof, paving, and areas surrounding the pool
• The pool backwash line
• Overflow drains and subsoil drains

It is crucial to recognise 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 discussion centres on the drainage lines, which are particularly susceptible to tree root intrusion.

How Do Tree Roots Lead to Blockages in Pool Drains?

Tree roots naturally gravitate towards moisture sources, and even a minor leak at a pipe joint can attract 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, it flourishes in the damp environment within the pipe, entrapping waste and debris, which ultimately results in a blockage.

When a drain near the pool becomes obstructed, backwash water lacks an escape route, potentially leading to flooding on the pool deck. If the blockage is within the sewer line, it may cause showers, toilets, and floor drains inside the house to back up.

If you are landscaping around a new pool, consult our guide on appropriate tree species to plant to prevent blocked drains. This guide provides information on trees that are safer to position near pipework.

What Are the Signs of a Blocked Pool Drain or Stormwater Line?

Be observant for the following indications 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 produces gurgling sounds when the pool is being backwashed
• Water accumulates on the pavers or lawn next to the pool

Each of these symptoms suggests a potentially blocked or damaged pipe underground, and a camera inspection will enable us to accurately identify the issue.

Why Should You Avoid Excavation Around a Pool?

Accessing the drainage around a pool can present significant challenges that often result 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. Following pipe repair, restoring the paving and landscaping can be both extensive and costly.

We favour relining methods over excavation. In a recent scenario, relining enabled 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 major concerns in their backyard:

• A blocked stormwater line adjacent to their in-ground pool
• Gurgling noises coming from the back garden
• Water pooling in a tiled corner

Our CCTV drain inspection uncovered significant root intrusion from a nearby tree, cracks in an old earthenware line, and multiple blocked junctions located approximately 3 metres beneath the pavers.

The accompanying images illustrate the scenario: the first shows the blocked pipe prior to intervention, while the second depicts the same pipe following the relining process.

Rather than recommending excavation, we implemented the following steps:

1. We cleared the line using high-pressure hydro jetting and root-cutting tools.
2. We installed a resin liner throughout the damaged section to seal the cracked junctions and joints.

The stormwater line was returned to optimal flow, with no disruption to the pavers or garden beds. The entire procedure was completed in under six hours.

What Is the Procedure for Pipe Relining Without Excavation?

We utilise a technique known as cured-in-place pipe relining. A resin-soaked liner is introduced into the affected section of the pipe, pressed against the interior surface, and allowed to cure, effectively creating 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 remain undisturbed.

Our dedicated team supervises every phase of the relining process, from the initial camera inspection to the final stages, without involving subcontractors. For further information on the process, please visit our pipe relining Sydney page.

When Is Pipe Relining Not Appropriate for Pool Drain Repairs?

Pipe relining is suitable for pipes that are damaged but retain most of their structure. If a section has collapsed to such an extent that a liner cannot be inserted, that segment will necessitate excavation and replacement. Similarly, if a section has subsided and lost its gradient, the liner will follow the dip, resulting in stagnant water, which requires reinstalling the pipe at the correct slope.

Occasionally, our camera inspections reveal that roots have penetrated the Sydney Water main rather than your private pipes. In such instances, the responsibility for repairs rests with Sydney Water, and we provide the footage necessary to facilitate the reporting process.

Common Queries Regarding Blocked Pool Drains

Can the Drain Pipes Surrounding a Pool Be Relined?

Certainly. We can reline the sewer and stormwater pipes situated beneath pool surrounds, provided the pipe maintains its shape. A camera inspection is conducted first to evaluate the damage and confirm that a liner can be installed. If any sections have collapsed or subsided, those areas will require excavation and replacement.

What Methods Are Employed to Repair 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 via an existing access point. This repair effectively seals the damage without necessitating the lifting of pavers, cutting of slabs, or disturbance of the garden.

What Are the Primary Causes of Blocked Drains Around Pools in Sydney?

Tree roots are a predominant cause we encounter around pools, particularly in older terracotta and earthenware pipes. Roots infiltrate joints that leak water and continue to grow until they trap debris. A camera inspection will assist in identifying 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 eliminate 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; 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.

Arrange a CCTV Inspection for Your Blocked Drain Near the Pool

We strive to find a method for repairing the drain from within the pipe before considering excavation, and we will share the camera footage prior to commencing any work.

If you observe signs of a blocked drain near your pool, schedule a CCTV inspection or contact The Blocked Drain Guys at 0418 408 333. Craig or a member of our team will clarify the inspection process and what we will be looking for.
