The Five Best Questions to Ask About Plumbing and Electric When Attending an Open Home
Attending an open home this summer? It’s easy to get swept up in the charm of a sunny living room or a freshly landscaped garden. But before you fall in love, it’s essential to dig deeper—particularly into the plumbing and electrical systems. Here are five crucial questions to ask that can save you from future headaches:
1. How old is the wiring, and when was the last electrical inspection?
In New Zealand, many older homes still have original wiring, which might not meet modern safety standards. If the wiring hasn’t been updated in decades, you could face issues with capacity, safety, and compliance.
Why ask? Outdated wiring (such as older rubber or aluminium types) can pose fire risks or fail to support the demands of modern appliances.
What to listen for: If there’s been a recent Electrical Installation Condition Report (EICR), it’s a good sign the system has been reviewed and deemed safe.
2. Are there RCDs (Residual Current Devices) installed?
RCDs are life-saving devices that cut power if they detect electrical faults. They’re a legal requirement for new builds in New Zealand and are highly recommended for older homes.
Why ask? Homes without RCDs might require an expensive upgrade to ensure safety.
What to look for: Check the switchboard for a test button marked with "RCD" or ask the agent for confirmation.
3. What kind of plumbing materials are in place?
The type of plumbing can give clues about potential problems. For example, older homes in New Zealand may still have galvanized steel pipes, which corrode over time, or aging polybutylene pipes, prone to leaks.
Why ask? Replacing plumbing can be a costly, disruptive project, so it’s good to know what you’re dealing with upfront.
What to look for: Modern homes typically use durable materials like copper or PEX (cross-linked polyethylene).
4. What’s the water pressure like, and where does the water come from?
Water pressure can vary depending on the home’s plumbing setup. Also, knowing the water source—whether it’s mains supply, a tank, or a bore—can impact your lifestyle and maintenance needs.
Why ask? Low water pressure could signal plumbing issues, while tank or bore systems may require extra upkeep.
What to look for: Ask if pressure regulators are in place and whether any filters or pumps need regular servicing.
5. Are there any outstanding compliance certificates for recent work?
If the current owners have renovated or upgraded systems, there should be certificates to confirm the work meets New Zealand building codes. This applies to both plumbing and electrical upgrades.
Why ask? Uncertified work could mean future legal or safety issues for you as the new owner.
What to look for: Ask for Certificates of Compliance (CoCs) for any recent installations or upgrades.
A Few Final Tips for Open Home Success
Bring a flashlight: Look under sinks, in the switchboard, and any visible crawlspaces for leaks or electrical hazards.
Take note of water heating systems: Older cylinders may be less efficient and could need replacing.
Don’t be afraid to ask for professional advice: If the answers to your questions aren’t reassuring, consider bringing in a qualified plumber or electrician for an independent inspection before making an offer.
By asking these questions at an open home, you’re not just inspecting a house—you’re protecting your investment. Armed with the right knowledge, you’ll be well-prepared to spot any potential red flags before signing on the dotted line.
Happy house hunting!
