Discovering there's a leak in a sewer or stormwater drain under your swimming pool is not a fun experience. It's definitely not a problem most homeowners would like to contemplate, however, discovering the waste water drain which runs under the swimming pool is leaking happens more often than you'd like to think.

Swimming pool drain pipe repair

Placing an above ground swimming pool or the paving or decking surrounding the pool over a major sewage or stormwater drain has been known to occur, often in older houses where the plumbing plans are not known or pipes and drains haven't been accurately located.

Nobody expects that they will need to get to those drains anyway, what could possibly happen to a pipe protected by 30-70 cms of dirt and thousands of litres of water?

In a word, lots.

Common drain problems

One of the most common drain issues we encounter is tree root intrusion, yes that same beautiful shade tree which prevents the pool from becoming a warm bath in the middle of summer could be wreaking havoc with the sewer or stormwater drains under your manicured buffalo grass.

The second issue we often find is drain pipe damage, often from the very equipment which was used to install the swimming pool in the first place. Heavy machinery can crack or crush sewer and stormwater drains simply by driving over the ground above the drain, leading to leaks and blocking the path of wastewater.

Poorly laid or very old sewer and stormwater drains can sustain damage over time causing them to break and leak household wastewater into the surrounding soil. Potentially creating further issues with ground movement and often seeping everything that goes down the sink and toilet in your home into the garden.

Stormwater and sewer drain repairs

Luckily, moving the swimming pool or pulling apart the deck and paving is not the only repair option you have for damaged stormwater or sewer drains thanks to modern pipe relining technology.

Repairing a broken drain under a swimming pool, or any other major structure in your garden, is now fairly straightforward and thankfully doesn't involve digging up huge areas of the yard.

An experienced drain repair team will first inspect the drain with a drain camera to find the exact location of the issue and to get a clear picture of the damage and repair requirements. Often a blockage caused by the damaged drain is found during this initial inspection. The clog must be cleared before any work can be carried out. This can easily be done using a high-pressure water jet or a small robotic cutter.

The drain may be inspected again using the CCTV drain camera to ensure all debris has been cleared away and to double-check repair requirements.

Your drain specialists will then place either a pipe patch or, if there is a large area of damaged drain, a section of long-lasting pipe lining through the nearest access point, positioning the patch or liner inside the cracked or broken section. The liner is then hardened in place to form a strong inner layer which provides a durable new drainpipe inside the old broken drain one.

Reline Solutions uses several different systems to repair drains, depending on the drain diameter and the extent of the damage. Your drain specialist will provide expert advice on which system is best for your drain issue.
