Straight Plumbing Answers Written by a Penrith Plumber.
This is where we write down the questions we get asked on site over and over: who pays when a blockage sits in the water authority’s main, what a gas compliance certificate actually proves, why one hot water swap costs more than the next. No filler and no scare tactics. Every entry is written by the plumber doing the work, checked against the current NSW rules, and links back to the source so you can read it yourself.

What a CCTV drain report actually shows you, and what makes it a report
A video file on a USB is not a report. There is a national code for this, WSA 05, and it covers house drains as well as sewers. A report written to it gives you coded defects, distances along the pipe, and two condition grades rather than one opinion.
How to unblock a drain: what works, and what quietly makes it worse
A plunger used properly shifts most household blockages. Baking soda and vinegar will not, and boiling water can damage PVC. The more useful question is whether it is coming back, because a drain that blocks twice in the same place is a defect, not a blockage.
How to turn the water off in an emergency, and what that tap tells you
Three shut-off points, and the one at the meter doubles as a diagnostic. Sydney Water owns the meter and lets you turn its tap on and off. If the flow stops when you close it, the fault is in your pipes. If it keeps running, it is theirs, and the number is 13 20 90.
The blockage is in Sydney Water’s main. Who pays for it?
You pay the plumber, then claim it back from Sydney Water. The order of the steps matters, the job number matters, and excavation or CCTV in their pipe needs their approval before it happens, not after.
Gas compliance certificates in NSW: what you should be handed, and what changed in 2026
Every piece of gasfitting work needs a certificate, whatever it cost. Since 1 March 2026 it has to be lodged through the BCNSW eCert portal, and emailed PDFs of the old paper form are no longer accepted.
What actually moves the price of a hot water replacement
The unit is rarely the part that swings the number. Seven things found on the day change a quote more than the brand on the box does, from where the old one sits to whether a tempering valve has to go on.
Low water pressure at home: what it is, and what a plumber checks first
Sydney Water has to deliver at least 15 metres head at your point of connection. Below that is their problem. Above it, the drop is happening on your side, and there is a short list of usual suspects.
