Tree Roots Blocking Pipes: Solutions for Your Pool Area

Your pool area may exude beauty, yet you could be grappling with ongoing drainage issues nearby. In the Sutherland Shire and southern Sydney, our advanced camera technology for investigating blocked sewer or stormwater lines adjacent to pools frequently uncovers the invasion of tree roots that have breached the joints of older piping systems.

Addressing a blocked pool drain doesn’t always necessitate lifting pavers or digging up your garden. This article delves into the factors that contribute to blockages, the techniques we employ to detect them, and how pipe relining provides a practical solution by tackling the problem from within the pipe itself.

What Drainage Systems Are Installed Beneath Your Backyard Pool?

In numerous backyard pools throughout Sydney, the surrounding area is typically adorned with paving, tiles, decking, retaining walls, and garden beds. Beneath these hard surfaces, you will generally discover several drainage lines:

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

It’s 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 concentrates on the drainage lines, which are particularly susceptible to tree root invasion.

How Do Tree Roots Cause Blockages in Pool Drains?

Tree roots inherently seek moisture, and even a minor leak at a pipe joint can attract them. Roots from trees situated several metres away can extend towards a compromised joint in older terracotta, earthenware, or PVC pipes. Once a small root infiltrates, it thrives in the moist environment within the pipe, accumulating waste and debris, ultimately resulting in a blockage.

When a drain adjacent to the pool becomes blocked, 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 overflowing showers, toilets, and floor drains inside the house.

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

What Symptoms Indicate a Blocked Pool Drain or Stormwater Line?

Stay 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 bubbles up 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 presence of a potentially blocked or damaged pipe underground, and a camera inspection will enable us to accurately identify the issue.

Why Is Avoiding Excavation Around a Pool Beneficial?

Gaining access to drainage around a pool can be a daunting task that often leads to 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. Following the repair of the pipe, restoring the paving and landscaping can be extensive and costly.

This is why we prefer relining methods rather than excavation. In the example highlighted below, relining enabled us to navigate 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 approached us with 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 three 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 post-relining process.

Rather than recommending excavation, we undertook the following measures:

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 its optimal flow, with no disturbance to the pavers or garden beds. The entire process was completed in under six hours.

What Does the Pipe Relining Process Involve Without Excavation?

We utilise a method known as cured-in-place pipe relining. A resin-soaked liner is inserted into the damaged section of the pipe, pressed against the inner surface, and allowed to cure, effectively creating a new pipe within the old one. This technique seals any cracks, leaking joints, and entry points that tree roots could exploit. Access to the pipe is achieved through an existing entry point, such as an inspection opening, ensuring that the surrounding pavers and garden remain undisturbed.

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

When Is Pipe Relining Inappropriate for Pool Drain Repairs?

Pipe relining is suitable for pipes that are damaged yet retain most of their shape. If a section has collapsed to such an extent that a liner cannot be inserted, that segment will require excavation and replacement. Similarly, if a section has sunk and lost its gradient, the liner will follow the dip, leading to stagnant water, which necessitates the 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 these instances, the responsibility for repairs lies with Sydney Water, and we provide the footage necessary to assist with the reporting process.

Common Queries About Blocked Pool Drains

Can the Drain Pipes Surrounding a Pool Be Relined?

Yes, we can reline the sewer and stormwater pipes situated 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 Methods Are Used to Resolve a Blocked Pool Drain Without Excavation?

We eliminate the blockage using high-pressure hydro jetting and root-cutting tools. Subsequently, 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 necessity to lift pavers, cut slabs, or disturb the garden.

What Common Problems Lead to Blocked Drains Around Pools in Sydney?

Tree roots are a primary issue 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 Accountable for Clearing 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 invade the junction at the connection point. If our camera footage reveals 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 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 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

Our goal is to identify a method for repairing the drain from within the pipe before considering excavation, and we will show you the camera footage 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 another member of our team will explain the inspection process and what we will be looking for.
