Effective Solutions for Tree Roots Blocking Pipes in Pools

While your pool area may present an appealing aesthetic, ongoing drainage problems nearby could be a concern. In the Sutherland Shire and southern Sydney, our advanced camera technology frequently uncovers invasive tree roots infiltrating the joints of older pipe systems, leading to blocked sewer or stormwater lines adjacent to pools.

Fixing a blocked pool drain does not always necessitate lifting pavers or excavating your garden. This article delves into the various factors that contribute to blockages, the methods we utilise to detect them, and how pipe relining can effectively resolve the issue from within the pipe itself.

What Are the Different Drainage Systems Located Under Your Backyard Pool?

In numerous backyard pools throughout Sydney, hardscapes such as paving, tiles, decking, retaining walls, and garden beds typically surround the area. Beneath these surfaces, several drainage lines are usually present:

• The sewer line from 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 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 focuses on the drainage lines, which are particularly susceptible to tree root intrusion.

How Do Tree Roots Contribute to Blockages in Pool Drains?

Tree roots naturally seek 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 small root gains entry, it thrives in the moist environment inside the pipe, gathering waste and debris, which eventually leads to a blockage.

When a drain located near the pool becomes obstructed, backwash water lacks an escape route, which can result in flooding on the pool deck. If the blockage occurs within the sewer line, it may cause showers, toilets, and floor drains inside the house to overflow.

If you are landscaping around a new pool, consider consulting our guide on appropriate tree species to plant, which helps prevent blocked drains. This guide provides insights into safer tree options to place near pipework.

What Warning Signs Point to 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 emits 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 enable us to accurately diagnose the issue.

What Are the Advantages of Avoiding Excavation Around a Pool?

Gaining access to drainage around a pool can prove to be a formidable task, often resulting in damage. Reaching a pipe typically entails lifting travertine or granite pavers, cutting through concrete slabs or retaining walls, or removing garden beds, turf, or decking. After repairing the pipe, the process of restoring the paving and landscaping can be extensive and costly.

This is why we prefer relining methods over excavation. In the example provided below, 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 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 three metres beneath the pavers.

The accompanying images illustrate the situation: 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 took 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 its optimal flow, with no disruption to the pavers or garden beds. The entire process was completed in under six hours.

What Steps Are Involved in the Pipe Relining Process Without Excavation?

We employ 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 process 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 aspect 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 Not a Suitable Solution for Pool Drain Repairs?

Pipe relining is suitable for pipes that are damaged but retain most of their shape. If a section has 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.

At times, our camera inspections reveal that roots have penetrated the Sydney Water main rather than your private pipes. In these 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?

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

What Methods Are Used to Clear 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 the need to lift pavers, cut slabs, or disturb the garden.

What Are the Main Causes of Blocked Drains Around Pools in Sydney?

Tree roots are a primary challenge 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 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 bears responsibility for their own pipes. According to Sydney Water’s guidelines on 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, and we will provide the necessary footage to facilitate the report.

How Long Does the Pipe Relining Process 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 vary based 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, please arrange a CCTV inspection or contact The Blocked Drain Guys at 0418 408 333. Craig or one of our team members will explain the inspection process and what we will be looking for.
