Tree Roots Blocking Pipes? Discover Effective Pool Solutions

Your pool area may be aesthetically pleasing, yet persistent drainage problems can diminish its charm. In the Sutherland Shire and southern Sydney, our investigations, leveraging advanced camera technology in blocked sewer or stormwater lines near pools, frequently uncover invasive tree roots that have infiltrated the joints of older pipework.

Addressing a blocked pool drain does not always necessitate lifting pavers or excavating your garden. This article delves into the causes of blockages, the detection techniques we utilise, and how pipe relining presents an effective solution by tackling the issue from within the pipe itself.

What Drainage Systems Lie Beneath Your Backyard Pool?

In many Sydney backyard pools, the surrounding area is commonly adorned with paving, tiles, decking, retaining walls, and garden beds. Beneath this hardscape, several drainage lines typically exist:

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

It is crucial to recognise that the pool’s filtration pipework, which links 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, particularly susceptible to tree root intrusion.

How Do Tree Roots Lead to Blockages in Pool Drains?

Tree roots are naturally drawn to moisture sources, and even a minor leak at a pipe joint can entice them. Roots from trees positioned several metres away can extend towards a cracked joint in older terracotta, earthenware, or PVC pipes. Once a small root penetrates, it flourishes in the moist environment within the pipe, capturing waste and debris, which ultimately culminates 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 occurs within the sewer line, it can result in backflow in showers, toilets, and floor drains inside the house.

If you are landscaping around a new pool, consult our guide on suitable tree species to plant in order to prevent blocked drains. This resource offers insights on trees that are safer to plant near pipework.

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

Remain alert for the following indicators 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 adjacent to the pool

Each of these signs may indicate a potentially blocked or damaged pipe underground, and a camera inspection will assist us in accurately locating the issue.

Why Should You Avoid Excavation Around a Pool?

Gaining access to the drainage around a pool can be a daunting task, often resulting 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. After repairing the pipe, restoring the paving and landscaping can be extensive and costly.

This is why we favour relining methods over excavation. In a recent case, 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 significant issues 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 considerable 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 situation: the first shows the blocked pipe before intervention, while the second depicts the same pipe after the relining process.

Instead of recommending excavation, we undertook 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 restored to optimal flow, with no disruption to the pavers or garden beds. The entire procedure was completed in under six hours.

What Is the Pipe Relining Process Without Excavation?

We utilise a method 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 left 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 stage of the relining process, from the initial camera inspection through to the final stages, without the involvement of subcontractors. For more 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 yet maintain most of their shape. If a section has collapsed to such an extent that a liner cannot be inserted, that section will require excavation and replacement. Similarly, if a section has subsided and lost its gradient, the liner will follow the dip, causing 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 instances, the responsibility for repairs lies with Sydney Water, and we provide the footage necessary to facilitate the reporting process.

Common Inquiries 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 retains its shape. A camera inspection is conducted initially to evaluate 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 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 through 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, 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 assist in pinpointing the specific cause of the blockage in your drain.

Who Is Accountable 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 regarding repair responsibilities, the owner must also clear tree roots that encroach on 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, referenced 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 aim to identify a method for repairing the drain from within the pipe before considering excavation, and we will present the camera footage to you before 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 explain the inspection process and what we will be looking for.
