    ⭐⭐⭐⭐⭐I had a fantastic experience with Clean Plumbing in Kellyville. Thanks Kevin, from the first call to the completed job, their service was professional, prompt, and stress-free. The plumber arrived on time, clearly explained the issue, and fixed it efficiently with no mess left behind. Pricing was fair and transparent, which I really appreciated. It’s refreshing to deal with a local business that genuinely cares about quality and customer satisfaction. Highly recommend Clean Plumbing to anyone in Kellyville looking for reliable, honest plumbing services!

    I’ve been using The Clean Plumbers for 20 years and they are always so lovely and courteous. I had Blake this time and he was no exception. He was on time, assessed the problem quickly and explained it all to me. The leaking hose was replaced with no problems, no mess and fast. Such a great service and company.

    Thank you to Stephen and Kevin for their excellent work during the Christmas break. Stephen realigned my father’s toilet seat and did a great job, thankfully, because it’s been a huge problem for my dad after several attempts from several plumbers. We also had a leak that was promptly detected and fixed in no time. We were happy with the very decent price and the seniors discount that my father was given. Stephen and Kevin were awesome guys that were lovely to speak to and they were also very tidy and respectful.

    We had a leaking tap right at the start of the new year, and keen to get it fixed but couldn’t get hold of the plumber we knew. It was pleasing to see The Clean Plumber has a user-friendly online booking system, and we are booked in for the next day in no time. Blake attended the job on-time on a searing hot day. He did a fantastic job, deserve a 5 out of 5 – he identified the issue quickly; explained the solution and price to us clearly before proceeding; he is skilful and cleaned up everything afterwards. Highly recommend!

    Our hot water system had recently given up on us. Blake came out on time and was fantastic to work with. Gave us an honest and reasonable upfront price to replace the system, and now we won’t have to worry about the system while we’re away.5 stars isn’t enough!

    5/5 my husband and I have had the most fantastic experience with multiple individuals from individuals from the Clean Plumber. This past Friday, Harry and Blake were very helpful and today Isacc and David were particularly helpful. A big shout out to Isacc who was so thorough in understanding the complexities occuring in a few units. He was also generous with his time in explaining and helping us understand everything. Highly recommend The Clean Plumbers and will definitely use them in the future

    Great experience with The Clean Plumber. David and Blake were awesome to deal with and got our hot water system replaced quickly, even over the Christmas/New Year break. Super easy process, no hassles at all, and they cleaned everything up before they left. Really impressed with the service 👍

    “Contacted Clean P from their fridge magnet and took up their seniors offer. They tidied up some taps and washers in some problem areas and were able to identify a few pressing issues. Price was reasonable and we went ahead to get them fixed. We are confident in their service and warranty and felt very secure due to their sound knowledge of matters”

    “The Clean plumber came to my home to investigate a roof leak. They diagnosed the issue and put in a plan of action to rectify it. I am convinced that had it not been for Damien’s foresight, the situation could have been a lot worse down the track.
    They are excellent plumbers and their knowledge and wisdom is unparalleled compared to other plumbers I have engaged in the past.”

    Mick

    “We contacted Clean Plumber after hours for a urgent matter, as we had a large pipe that burst on our acreage property. They turned up within the hour and immediately stopped the leaking.
    We were very impressed with the quick service as we live in a semi rural area. They came back a few days later and replaced the faulty section of the pipe. All in all a very happy customer!”

    Signs You Need Sub Soil Drainage

    If you’ve noticed any of these issues, your property may require a sub soil drainage solution:

    Persistent water pooling in your yard
    Moisture or dampness around the foundation of your home
    Water leaking into basements or underground spaces

    Why Should You Contact The Clean Plumber?

    With decades of experience providing plumbing services across Sydney, we understand the unique challenges homeowners face with drainage issues.

    Our team delivers:

    Expertise in installing sub soil drainage systems tailored to Sydney’s conditions.
    Transparent, upfront pricing with no hidden fees.
    High-quality workmanship using durable materials.
    A commitment to customer satisfaction, backed by our 5-star review average on Google and trusted by thousands of homeowners.

    We also offer related services such as pipe relining and general plumbing solutions, ensuring all your plumbing needs are covered.

    Our Drainage Services

    At The Clean Plumber, we offer a range of sub soil drainage services tailored to meet the needs of Sydney homeowners. Whether you’re dealing with water pooling in your yard or moisture issues in your basement, we can help.

    Custom System Design

    We carefully assess your property to identify problem areas and design drainage systems that effectively redirect water away from foundations, basements, and outdoor spaces.

    Installation and Repairs

    We use durable, high-quality materials for installations and provide reliable repairs for existing systems that aren’t functioning as they should.

    Stormwater Drainage Solutions

    We ensure excess rainwater is effectively managed, complementing our stormwater drainage services.

    Types of subsoil drainage systems

    Subsoil drainage (also called subsurface drainage) removes excess water and excess moisture from the ground to protect your yard and your home’s foundation. Common systems include:

    Perforated pipe drains (the most common type) – perforated drainage pipe, often perforated pipes underground or slotted pipe, laid in a gravel layer to collect and redirect water away from the affected area.
    Gravel or mole drains – gravel mole drains or mole drains use a narrow trench and a coarse gravel bed to improve flow in heavy clay or after heavy rainfall.
    Interceptor drains – surface or shallow drains that catch excess surface water before it soaks deeper into the soil.
    Groundwater pumps – where the water table or excess ground water is high, a pumped solution removes drainage water to a safe outlet.

    These systems use subsoil drainage pipes, underground pipe and drainage pipe types chosen for your soil type, slope and the amount of water to remove.

    How to Decide Which System is Best for You

    Choosing the right sub soil drain depends on site conditions, not a one-size-fits-all answer. We assess:

    Soil and clay content, moisture content and soil health (clay soils hold more water).
    Water source – is it surface water, subsurface water or rising groundwater?
    Where water collects (soggy backyard, standing water near the home or flow toward the home’s foundation).
    Nearby structures, such as retaining walls, paths or other structural components that could be affected.
    Local council rules or required depths and outlets.

    The Clean Plumber’s qualified team inspects the affected area, tests drainage and water table, then recommends a cost-effective solution, from a simple drainage pipe and gravel trench, to mole drainage or a pumped system. We aim for minimal disruption, protect your soil and plants and maintain structural integrity.

    Benefits of Subsoil Drainage Installation

    Installing a subsoil drainage system offers many benefits:

    Removes excess ground water and surface water from your property.

    Prevents standing water, soggy lawns and garden damage.

    Protects your home’s foundation and structural components from water intrusion.

    Reduces risk of soil erosion and improves soil health.

    Increases aeration in soil for healthier plants and better growth.

    Prevents flooding and water damage to outdoor and indoor areas.

    Provides a long-term solution to recurring poor drainage and water intrusion issues.
