What we do for Tewantin homes and businesses

Blocked drains, sewer and stormwater
Drains are our speciality, and it is right there in the name. We use a CCTV drain camera to find exactly what is blocking the pipe and high pressure water jetting to clear it, whether that is tree roots, grease or a build up of debris. We offer same day drain service. See how we unblock drains for more detail.
For yards that flood every time it pours, we design, install and maintain stormwater solutions, including ag pipes, pits and absorption trenches, to Queensland standards.
24/7 emergency plumbing
Burst pipe at midnight, sewage coming up the shower drain, or water spreading across the floor? Call us any time, day or night. Our emergency plumbing page covers what to switch off while you wait.

Hot water repairs and replacement
We repair, replace and install gas, electric and heat pump hot water systems, and we service all brands, including Rheem, Rinnai, Dux, Bosch and Thermann. Most systems last 8 to 12 years, so if yours is getting on, we can tell you honestly whether a repair is worth it. If not, our temporary plug in unit keeps you going until the new one is in. Find out more about replacing or repairing your hot water.
Leak detection
If your water bill has jumped or a damp patch is spreading on a wall or ceiling, we track the leak down with compressed air testing and thermal imaging. Finding it first means fewer holes cut in your walls.

Renovations, maintenance and everyday plumbing
From leaking taps and running toilets to full bathroom, kitchen and laundry renovations, we handle the plumbing side from start to finish, including plumbing approvals through Noosa Council where your renovation needs them. We also install and maintain rainwater tanks, pumps and whole house water filtration.
Common plumbing problems in Tewantin homes
Here is what tends to come up in a town with a mix of older and newer homes.
| Problem | Why it happens | What we do |
|---|---|---|
| Drains that keep blocking | Tree roots getting into older sewer and stormwater joints | Camera inspection, high pressure jetting, then a quote for a longer term fix |

| Hot water running cold or leaking | Ageing systems reaching the end of their life | Repair where it makes sense, or supply and install a new system |
| Rising water bill | A hidden leak in the water service or inside a wall | Pressure testing and thermal imaging to find it |

A quick seasonal checklist for Tewantin homes
- Before storm season, clear leaves from gutters, downpipes and stormwater pits.
- Walk the yard after heavy rain. Note where water pools. That tells you where drainage is struggling.
- Check the age of your hot water system. The install date is usually on the label. If it is past 10 years, start planning a replacement.
- Watch slow drains. If the shower or kitchen sink is slowing, get it looked at before it blocks fully.
- Read your water meter with every tap off. If it is still moving, you may have a leak.
- Know where your water meter is. In an emergency, turning it off fast saves a lot of damage.
