Tree Roots Blocking Pipes: Solutions for Your Pool Area

Your pool area may be aesthetically pleasing, yet it could be plagued by ongoing drainage complications nearby. In the Sutherland Shire and southern Sydney, we frequently utilise advanced camera technology to examine blocked sewer or stormwater lines adjacent to pools. Our investigations often uncover that invasive tree roots have infiltrated the joints of aging pipe systems.

Addressing a blocked pool drain does not always necessitate the lifting of pavers or excavation of your garden. This article delves into the various factors that contribute to blockages, the techniques we employ for accurate identification, and how pipe relining provides an effective solution by resolving the issue from within the pipe itself.

What Drainage Systems Are Located Beneath Your Backyard Pool?

In many Sydney backyard pools, the surrounding area is typically covered with paving, tiles, decking, retaining walls, and garden beds. Beneath these hard surfaces, several drainage lines are usually present:

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

It is vital to distinguish that the pool’s filtration system, which includes the pump, filter, skimmer box, and return jets, operates under pressure and is separate from the drainage systems. This article will concentrate on the drainage lines, which are particularly susceptible to invasion by tree roots.

How Do Tree Roots Lead to Blockages in Pool Drains?

Tree roots naturally pursue moisture, and even a minor leak at a pipe joint can attract them. Roots from trees positioned several metres away can extend toward a compromised joint in older terracotta, earthenware, or PVC pipes. Once a small root infiltrates, it thrives in the damp environment within the pipe, accumulating waste and debris, which ultimately results in a blockage.

When a drain near the pool becomes blocked, the backwash water has no avenue for escape, 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 home.

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 features 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 symptoms indicates a potentially blocked or damaged pipe underground, and a camera inspection will allow us to accurately identify the issue.

Why Should You Avoid Excavation Around a Pool?

Gaining access to drainage around a pool can be a formidable challenge 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 the reason we favour relining methods over excavation. In the example illustrated below, relining enabled us to manoeuvre 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 approached us with three significant concerns in their backyard:

• A blocked stormwater line adjacent to their in-ground pool
• Gurgling sounds originating 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 accompanying images illustrate the situation: the first shows the blocked pipe before intervention, while the second depicts the same pipe after the relining process.

Rather than proposing excavation, we undertook the following actions:

1. We cleared the line with 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 without disturbing 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 technique known as cured-in-place pipe relining. A resin-soaked liner is introduced into the damaged section of the pipe, pressed against the inner surface, and left to cure, effectively creating a new pipe within the existing one. This method 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 oversees every phase of the relining process, from the initial camera inspection to the final stages, without subcontractors. For further information regarding 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 maintain most of their original shape. Should a section have collapsed to the 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, necessitating 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 such instances, the responsibility for repairs falls to Sydney Water, and we provide the footage necessary to assist with the reporting process.

Common Questions Regarding 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, provided the pipe retains its shape. A camera inspection is conducted first 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 by employing 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 the need to lift pavers, cut slabs, or disturb the garden.

What Common Issues Contribute to Blocked Drains Around Pools in Sydney?

Tree roots are a predominant 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 assist in identifying 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, 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

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