Drainage System Upgrades and Replacements Newcastle

Upgrading your drainage system helps stop recurring problems and protects your property from water damage. If you’re dealing with constant blocked drains, frequent flooding, or old pipes that keep failing, a drainage upgrade or replacement might be the permanent solution you need.


At Leak Hunters, we provide professional drainage system upgrades throughout Newcastle and surrounds, helping homeowners replace old, damaged systems with modern solutions that last. As your trusted local plumber, we handle everything from partial upgrades to complete system replacements for sewer and stormwater drainage.

What are Drainage System Upgrades?

Drainage system upgrades involve replacing your old or failing pipes with new, modern drainage infrastructure. This might mean replacing sections of damaged pipes, upgrading your drainage system for a better flow, or installing a completely brand new drainage system. 

Upgrades fix the underlying issues that cause frequent blocked drains, flooding, and water damage. Modern pipework and proper installation extend the lifespan of your system and reduce your plumbing maintenance costs over time.

When should I Upgrade vs Repair?

Knowing when to repair or when to upgrade depends on the overall condition of your existing system and how often you get plumbing problems. 

When to Repair?

  • The problem is only in just one section of your drainage system 
  • CCTV inspection shows minor cracks or small blockages
  • Your drainage system is relatively new (less than 20 years)
  • Pipe relining can fix the damaged section
  • You’ve only had one or two drainage issues

When to Upgrade?

  • Problems keep happening in multiple locations
  • Your pipes are older (40+ years) 
  • CCTV inspection shows widespread deterioration or a collapsed pipe
  • You’ve had multiple blocked drains in the past year
  • The drainage system was installed incorrectly
  • You’re extending your home or adding bathrooms
  • Your property floods regularly during heavy rain

Not sure? Our team can inspect your system and give you honest advice on whether you should organise a repair, or a complete drainage system upgrade works better for your home or budget. 

Benefits of Upgrading Your Drainage System

  • Stops recurring drainage problems: No more calling for a Newcastle plumber every few months. A new system fixes the problem at the cause
  • Protects your property investment: Proper drainage systems prevent water damage to your foundations, retaining walls, driveways and landscaping
  • Improves water flow: Modern drainage systems handle a higher volume of water and drain it faster, which helps reduce your risk of flooding during heavy rains
  • Reduces long-term maintenance costs: New drainage systems last 50+ years with minimal maintenance compared to older pipes

Frequently Asked Questions

The cost will depend on the complexity of the work needed. A full upgrade will cost you more money upfront, but save you thousands of dollars in the long run. After we complete a plumbing inspection, we’ll provide you with an upfront quote with no hidden costs. 

Most residential drainage upgrades in Newcastle will take anywhere between 2-5 days. We’ll give you an accurate timeframe after inspecting your property. 

Sometimes. Minor repairs and matching replacements might not need council approval. Major system changes or new connection points usually require council approval. We'll work with you on any requirements and ensure all work meets regulations.

Tree roots are one of the main reasons homeowners need drainage upgrades. We remove the roots during the upgrade and install modern PVC pipes with smooth joints that resist root intrusion much better than old terracotta pipes.

Yes. If only one section is damaged, we can upgrade that section and integrate it with your existing system. However, if your entire system is old, upgrading just one section might mean other parts fail soon after. Call 02 4006 8330 for advice on the most cost-effective approach.
