If you’ve driven through Narangba, Morayfield, or Burpengary lately, you’ll know one thing for sure — new homes are going up everywhere. From fresh estates to infill developments, the whole region is booming with new builds.
So, we thought it was the perfect time to talk about what matters when it comes to plumbing in a new home. Because while most people get caught up choosing tiles, benchtops and tap styles, there are decisions happening behind the walls that can seriously impact your home’s function (and your wallet) for years to come.
At RJT Plumbing & Gas, we’ve seen the good, the bad, and the “what were they thinking?” moments in new builds across the Moreton Bay region. So before your slab’s down or the walls go up, here’s what you should be thinking about.

1. Hot Water Systems: Don’t Let the Builder Decide What’s “Good Enough”
One of the most overlooked decisions in a new build is the type of hot water system you get — and unfortunately, most builders don’t give it much thought either. In places like Narangba, Morayfield, and Burpengary, the standard builder inclusion is usually a basic electric storage system. Why? Because it’s cheap, familiar, and gets the job done — at least on paper.
But here’s the thing:
That “included” hot water system could end up costing you hundreds extra every year in electricity. And worse — it might not even keep up with your household’s demand once you’re actually living in the place.
Here’s a breakdown of your main options:
Electric Storage (Builder Default)
- Works fine, but chews through power
- Often installed on a flat rate or off-peak tariff
- Struggles in larger households or high-use scenarios
- Least efficient option long-term
Gas Continuous Flow (Great for Morayfield & Burpengary)
- Heats water only as needed — no tank
- Never runs out, even with back-to-back showers
- Lower running costs if natural gas is available (check with your builder)
Solar Hot Water with Electric Booster (Ideal for Narangba’s sunny blocks)
- Uses rooftop solar collectors to heat water for free
- Booster element kicks in on cloudy days
- Much lower running costs — especially over 10–15 years
- Consider roof positioning when planning
Heat Pump Systems (All-electric with great efficiency)
- Looks like an air conditioner attached to your hot water tank
- Extracts heat from the air to warm your water
- Great for energy-conscious builds, even without solar panels
If you’re building in any of these growth suburbs, it’s worth thinking about how your family will actually use hot water day to day. Early morning showers? Teenagers? Guests? Big bath tubs? Don’t assume the cheapest inclusion will cut it.
And remember — it’s much cheaper and cleaner to install the right system now than it is to rip one out and upgrade it later.
2. Water Pressure & Flow: Don’t Find Out Too Late
It’s one of the most common complaints we hear from people who’ve just moved into their brand-new home:
“Why can’t we run two showers at the same time without one going cold?”
“Why does the pressure drop every time someone flushes the loo?”
In high-growth areas like Narangba, Morayfield, and Burpengary, a lot of new homes are being built fast — and unfortunately, some builders take shortcuts on plumbing design to save time or money. The result? Annoying daily issues that are completely avoidable with a bit of upfront planning.
Here’s what you need to consider:
Pipe Sizing and Layout
If your home has multiple bathrooms, a butler’s pantry, outdoor taps, and maybe a future granny flat or pool — your plumbing needs to be sized accordingly. That means:
- Larger main lines
- Smartly routed pipework to prevent pressure drop-offs
- No weird loops or excessive joins that slow flow
Pressure-Limiting Valves (PLVs)
Most new homes in the Moreton Bay region are fitted with PLVs by default — and that’s not necessarily a bad thing. They protect your fixtures and plumbing from excessive mains pressure. But:
- If set too low, you’ll feel it every time someone turns on another tap
- If installed incorrectly, it can lead to uneven performance across the house
Future-Proofing for Growth
Morayfield and Narangba are both seeing a lot of dual-living setups and multi-gen homes being built. Even if you’re not there yet, planning for future plumbing demand is smart — especially if you ever want to add value later.
We always recommend getting a flow test done before handover. It’s a simple check that can save you years of annoyance. And if you’re not sure your builder’s plumber has done one? We’re happy to double-check it for you.
Don’t let pressure problems become part of your daily life. They’re a pain to fix after the build is done — but easy to prevent if you catch them early.
3. Stormwater & Drainage: It’s Not Just About Where the Water Goes
You wouldn’t think stormwater would be a big issue in a brand-new home, right? But we’ve seen it too often — brand-new properties in places like Burpengary East or Morayfield South with soggy backyards, overflowing downpipes, or even worse, water creeping towards the slab.
And when you bring it up with the builder?
“Oh, that’s just surface water, it’ll drain eventually.”
Right.
Truth is, stormwater and drainage design is one of the most overlooked parts of new construction, especially in these booming parts of Moreton Bay where land can be flat, clay-heavy, or flood-prone.
Here’s what you really need to watch out for:
1. Downpipe and Gutter Positioning
It’s not enough to just have them — they need to be correctly placed and connected to a system that can handle heavy QLD summer rain.
- We’ve seen new homes in Narangba Heights with water pooling right at the footings because the downpipes were directed straight onto turf with no runoff path.
- Ensure your stormwater lines connect properly to street drainage or an on-site detention system, depending on council requirements.
2. Overflow Relief Gully (ORG)
The ORG is that little grate outside your bathroom or laundry. Most homeowners don’t know what it does — until something backs up.
- It’s designed to release sewage externally if there’s a blockage in the system.
- If it’s missing, buried, or installed incorrectly, you could end up with raw sewage inside the house.
This is not a “maybe later” fix. You need it right from day one.
3. Yard Drainage
Got retaining walls, side access paths, or garden beds planned? Good. Now make sure there’s somewhere for excess water to go.
- Consider aggie drains or surface strip drains if water tends to collect
- In Burpengary and low-lying parts of Morayfield, we often recommend adding simple gravel pits or extra pipework to help with soakage
Future-proof tip:
Even if your yard looks dry now, watch it during heavy rain (especially during construction). If there’s any sign of pooling, it’s 10x easier to add drainage before landscaping goes in.
4. Kitchen and Bathroom Layout: Think Access, Not Just Aesthetics
We get it — you’re picking out tapware, tiles, and that perfect floating vanity that’ll look great on Instagram. But once the sparkle fades, you’ll be left with the plumbing underneath… and that’s where smart planning counts.
Here’s what to lock in before the walls go up:
- Isolation valves on every major outlet (sinks, toilets, dishwasher, fridge). That way, when something leaks or needs fixing, you can turn off one tap — not the entire house.
- Access clearance behind your dishwasher and under-sink areas. Future you will thank you when it’s time to install a water filter or replace a tap.
- Stick with quality mixers and tapware. We’ve lost count of how many builder-standard fittings we’ve replaced within 2–3 years because they corrode, seize up, or snap.
And remember: the layout you choose now will determine whether small jobs down the line are five-minute fixes or full-blown kitchen dramas.
5. Outdoor Plumbing: Plan Ahead or Pay Later
Thinking about an outdoor kitchen one day? Want to add a pool, irrigation, or just run a hose to the veggie garden? Do the plumbing rough-in now.
Adding outdoor plumbing after your home is finished often means trenching through landscaping or drilling through brickwork — expensive, messy, and usually avoidable.
What to rough-in from day one:
- Capped gas point and waste outlet for a future BBQ or outdoor kitchen
- Dedicated outdoor tap lines, ideally separate from indoor pressure
- Greywater system prep, if you’re into sustainability
- Fridge water point — even if you don’t have a plumbed fridge yet, you might later
In fast-growing parts of Narangba and Morayfield, we’ve seen families kick themselves for not thinking a few years ahead. A small bit of prep during the build gives you a lot more freedom later.
6. Smart Features: Small Tech, Big Wins
Plumbing tech isn’t just for luxury builds anymore — it’s becoming the new standard in modern homes, especially in places like Burpengary East where new estates are all about convenience and efficiency.
Smart upgrades to consider:
- Leak detection systems that alert you to hidden drips before they become disasters
- Whole-house water filtration to remove chlorine, sediment, and heavy metals — especially if you’re sensitive to water quality
- Smart irrigation controls that link to weather forecasts and automate watering (great if you travel or forget)
In areas like Narangba where mains pressure can fluctuate and soil movement affects older pipes, investing in these systems can save you money and extend the life of your plumbing.
