He was at my studio within an hour of calling him and fixed the issue before we were due to open for the day. peter mills John was here quickly. Did a great job. Highly recommended. I’m handing his details to our strata manager and building manager. Gaurav Nanda John and his team at JET Plumbing Sydney are fantastic! I reached out to John from JET Plumbing Sydney as I had blocked drain in my bathroom. While trying to fix it myself I literally broke the thing. John was swift, efficient and came over to my place quickly to look at the issue and offered genuine advice. The quote John provided was far lesser than the other that I got. Clearly John knows what he is doing and is also affordable. It shows that no job is too big or small for John and his team at JET Plumbing Sydney and I did learn that they do bigger jobs such as bathroom fit outs, blocked drainage, installing gas etc..

- Pro Tip
If multiple drains are blocked simultaneously, the issue is likely in your main sewer line — not individual fixtures. Call a professional immediately.
- DIY Fixes You Can Try at Home
Blocked drains don’t happen overnight. There are usually clear warning signs before a full blockage occurs. Catching them early can save you hundreds — or even thousands — in plumbing repairs.
1. Boiling Water
Pour a full kettle of boiling water directly down the drain in two to three stages, waiting a few seconds between each pour. This dissolves soap scum and minor grease build-up.
2. Baking Soda & Vinegar
Pour half a cup of baking soda followed by half a cup of white vinegar. Cover the drain and wait 30 minutes, then flush with hot water. The chemical reaction helps break down organic matter.
3. Plunger
A good quality plunger can dislodge blockages in toilets and sinks. Ensure you have a tight seal and use firm, consistent strokes for best results.
- Warning
Never use chemical drain cleaners on old or PVC pipes — they can cause serious damage. If a plunger doesn’t work after 10 minutes, stop and call a licensed plumber.
