Plumbing problems can strike at any time. We’ve gathered some of the most frequently asked plumbing questions online—and provided practical tips to help you out.
Why Is My Tap Dripping?
A dripping tap is one of the most common plumbing issues. Usually, it’s caused by a worn-out washer or cartridge. Replacing the washer often fixes the problem. If the dripping continues, it may be due to corrosion or a more serious valve issue—best handled by a licensed plumber.
Tip: Fix a dripping tap quickly. Even a slow drip can waste litres of water each day and increase your bill.
How Do I Unblock A Drain?
Blocked drains are often caused by hair, grease, food scraps, or foreign objects. Start with a plunger or a natural remedy like baking soda and vinegar. If that doesn’t work, you may need a plumber with specialist equipment like a water jetter or CCTV camera.
Tip: Avoid pouring cooking oil down the sink—it solidifies and clogs pipes.
Why Is My Water Pressure Low?
Low water pressure can be caused by leaks, clogged pipes, faulty valves, or problems with the mains supply. If the issue is isolated to one fixture, the aerator may be blocked. If it’s throughout your home, you’ll likely need professional help to find the cause.
Tip: Clean tap aerators regularly to keep water flow strong.
How Do I Know If My Toilet Is Leaking?
A silent toilet leak can waste hundreds of litres a day. One simple test: put a few drops of food colouring in the cistern and wait 15 minutes. If the colour seeps into the bowl without flushing, you have a leak.
Tip: Get toilet leaks repaired quickly—they can add significant costs to your water bill.
Why Does My Hot Water Run Out So Quickly?
If your hot water doesn’t last, your cylinder may be too small for your household, the thermostat may be faulty, or sediment could be building up inside.
Tip: Regular servicing of your hot water system extends its life and keeps it running efficiently.
What Should I Do In A Plumbing Emergency?
Burst pipes, severe leaks, and overflowing toilets can cause major damage. The first step is to turn off the main water supply. Then, call a licensed plumber immediately.
Tip: Know where your water shut-off valve is located before an emergency happens.
Can I DIY Plumbing Repairs?
Simple tasks like changing a washer or unclogging a drain might be DIY-friendly. But in New Zealand, most plumbing and gasfitting work must be carried out by a licensed professional by law.
Tip: Always check what you’re legally allowed to do before attempting plumbing work yourself.
