Tree Roots Blocking Pipes: Solutions for Your Pool Area

Your pool area may look stunning, yet you could be dealing with ongoing drainage challenges in the vicinity. In the Sutherland Shire and southern Sydney, our advanced camera technology for examining blocked sewer or stormwater lines near pools frequently uncovers invasive tree roots that have infiltrated the joints of older piping systems.

Addressing a blocked pool drain does not always necessitate the removal of pavers or excavation of your garden. This article delves into the various factors that lead to blockages, the methods we utilise to detect them, and how pipe relining presents an effective solution by tackling the issue from within the pipe itself.

What Drainage Systems Are Typically Found Beneath Your Backyard Pool?

In numerous backyard pools across Sydney, the surrounding area is often covered with paving, tiles, decking, retaining walls, and garden beds. Beneath these solid surfaces, you will typically discover several drainage lines:

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

It is crucial to understand that the pool’s filtration system, which connects the pump, filter, skimmer box, and return jets, operates under pressure and is separate from the drainage systems. This article specifically addresses the drainage lines, which are particularly susceptible to tree root intrusion.

How Do Tree Roots Lead to Blockages in Pool Drains?

Tree roots instinctively search for moisture, and even a minor leak at a pipe joint can attract them. Roots from trees positioned several metres away can extend towards a compromised joint in older terracotta, earthenware, or PVC pipes. Once a tiny root gains entry, it thrives in the moist environment within the pipe, collecting waste and debris, which ultimately results in a blockage.

When a drain adjacent to the pool becomes obstructed, the backwash water lacks an escape route, potentially causing flooding on the pool deck. If the blockage occurs within the sewer line, it can lead to overflow issues in showers, toilets, and floor drains inside the home.

If you are landscaping around a new pool, consider consulting our guide on suitable tree species to plant, which provides recommendations to prevent blocked drains. This guide includes details on trees that are safer to place near pipework.

What Symptoms Indicate a Blocked Pool Drain or Stormwater Line?

Remain alert for the following signs around your pool and within your home:

• Pool water drains slowly or backs up during backwashing
• The backwash line overflows
• Water emerges through a garden drain or grate
• A sink or shower produces gurgling sounds while the pool is being backwashed
• Water accumulates on the pavers or lawn adjacent to the pool

Each of these indicators suggests the likelihood of a blocked or damaged pipe underground, and a camera inspection will enable us to accurately determine the issue.

Why Should You Avoid Excavation Around Your Pool?

Gaining access to drainage around a pool can be a complex task that often results in damage. Reaching a pipe typically involves lifting travertine or granite pavers, cutting through concrete slabs or retaining walls, 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. The example illustrated below demonstrates how relining allowed us to navigate around steep stairs and an established garden without causing any disruption.

Case Study: Effective Pipe Relining Solutions Near a Pool in Sutherland Shire

A homeowner in the Sutherland Shire reached out to us with three significant concerns regarding 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 considerable root intrusion from a nearby tree, cracks in an old earthenware line, and multiple blocked junctions located approximately three metres beneath the pavers.

The images provided illustrate the situation: the first shows the blocked pipe prior to intervention, while the second depicts the same pipe after the relining process was completed.

Instead of recommending excavation, we undertook the following actions:

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 without disrupting the pavers or garden beds. The entire process was completed in under six hours.

What Is the Pipe Relining Process That Avoids Excavation?

We utilise a method known as cured-in-place pipe relining. A resin-saturated liner is inserted into the damaged section of the pipe, pressed against the inner surface, and left to cure, effectively creating a new pipe within the old one. This approach seals any cracks, leaking joints, and entry points that tree roots could 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 manages every step of the relining process, from the initial camera inspection to the final stages, without the involvement of subcontractors. For further details on the procedure, please visit our pipe relining Sydney page.

When Is Pipe Relining Not an Option for Pool Drain Repairs?

Pipe relining is suitable for pipes that are damaged but still maintain most of their shape. If a section has collapsed to such a degree that 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, leading to stagnant water, necessitating the reinstallation of 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 falls to Sydney Water, and we can provide the footage necessary to assist with the reporting process.

Common Questions About Blocked Pool Drains

Is It Possible to Reline the Drain Pipes Surrounding a Pool?

Yes, we can reline the sewer and stormwater pipes located beneath pool surrounds, provided the pipe retains its shape. Initially, a camera inspection is conducted to assess the damage and confirm that a liner can be installed. If any sections have collapsed or sunk, those areas will need to be excavated and replaced.

What Methods Are Used to Resolve a Blocked Pool Drain Without Excavation?

We eliminate 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 Problems Lead to Blocked Drains Around Pools in Sydney?

Tree roots are a major issue 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 help pinpoint 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 remove 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 to facilitate the report.

How Long Does Pipe Relining Take When Conducted Near a Pool?

The relining project in Sutherland Shire mentioned earlier 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 conducting the camera inspection.

Arrange a CCTV Inspection for Your Blocked Drain Near the Pool

Our goal is to identify a method for repairing the drain from within the pipe before considering excavation, and we will share the camera footage with you prior to commencing any work.
