Tree Roots Blocking Pipes? Solutions for Pool Issues

Your pool area may boast aesthetic appeal, yet you could be grappling with ongoing drainage complications in the vicinity. In the Sutherland Shire and southern Sydney, our detailed investigations utilise camera technology to inspect blocked sewer or stormwater lines near pools, often uncovering invasive tree roots that have infiltrated the joints of older pipe systems.

Addressing a blocked pool drain does not always necessitate the removal of pavers or excavating your garden. This article delves into the underlying causes of blockages, the advanced detection techniques we employ, and how pipe relining presents a viable solution by tackling the issue internally within the pipe itself.

What Drainage Systems Lie Beneath Your Backyard Pool?

In many Sydney backyard pools, the surrounding environment 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 stemming 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 pipework, which links the pump, filter, skimmer box, and return jets, operates under pressure and functions independently of the drainage systems. This discussion centres on the drainage lines, which are particularly susceptible to tree root intrusion.

In What Ways Do Tree Roots Contribute to Blockages in Pool Drains?

Tree roots possess an innate attraction to moisture, and even a minor leak at a pipe joint can lure them in. Roots from trees located several metres away may extend 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, capturing waste and debris, which ultimately leads to a blockage.

When a drain adjacent to the pool becomes obstructed, backwash water is unable to escape, potentially resulting in flooding on the pool deck. If the blockage occurs within the sewer line, it may lead to backups in showers, toilets, and floor drains within the house.

If you are landscaping around a new pool, consult our guide on suitable tree species to plant to mitigate the risk of blocked drains. This guide provides insights into trees that are safer to position in proximity to pipework.

What Symptoms Suggest a Blocked Pool Drain or Stormwater Line?

Stay alert for the following signs around your pool and within your residence:

• Pool water drains sluggishly or backs up during backwashing
• The backwash line overflows
• Water seeps 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 indicators points to a potentially blocked or damaged pipe underground, and a camera inspection will accurately pinpoint the issue.

Why Should You Avoid Excavation Near a Pool?

Gaining access to the drainage around a pool can prove to be a challenging endeavour 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. Following the repair of the pipe, restoring the paving and landscaping can be both extensive and costly.

For this reason, we favour relining methods over excavation. In a recent project, relining allowed 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 concerns 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 uncovered considerable root intrusion from a nearby tree, cracks in an aged earthenware line, and multiple blocked junctions situated 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 executed the following steps:

1. We cleared the line using high-pressure hydro jetting and root-cutting equipment.
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 disturbing the pavers or garden beds. The entire process was finalised in under six hours.

What Steps Are Involved in Pipe Relining Without Excavation?

We utilise a method known as cured-in-place pipe relining. A resin-impregnated liner is inserted into the affected section of the pipe, pressed against the interior surface, and left to cure, effectively forming a new pipe within the existing one. This process seals any cracks, leaking joints, and entry points exploited by tree roots. 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 manages every aspect of the relining process, from the initial camera inspection to the final stages, without involving subcontractors. For further details 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 a degree that a liner cannot be inserted, that section 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 infiltrated the Sydney Water main rather than your private pipes. In such cases, the responsibility for repairs falls to 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 located beneath pool surrounds, provided the pipe retains 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 subsided, those areas 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 significant cause we encounter around pools, particularly 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 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, 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

We strive to find 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.
