New Build Plumbing in Clear Island Waters

The full plumbing scope on a typical canal-front new build:

• Pre-slab drainage and through-slab penetrations, larger homes with more wet areas, often 3-4 bathrooms plus powder room plus kitchen plus laundry plus outdoor kitchen.
• Sewer connection to council main (universal in canal suburbs).
• Water service from meter with pressure-limiting valve, isolation valves at every wet area plus separate isolators for the outdoor scope.
• Gas rough-in (natural gas universal in canal areas), cooktop, hot water, BBQ, pool heater, often outdoor fireplace or fire pit, gas heater for the main living area.
• Hot and cold rough-in to every internal wet area with premium isolation and manifolds.
• Hot water system, often gas continuous flow plus a secondary heat pump or solar for the pool and outdoor kitchen. Canal homes use significant hot water and the redundancy is worth specifying.
• Premium tapware fit-off, Phoenix Vivid, Sussex Voda, Astra Walker, Gareth Ashton, often with bespoke specifications across the home (different brassware in main vs powder vs ensuite).
• Outdoor entertaining scope: pontoon fresh-water tap (with stainless or marine-grade fittings), pool top-up auto-fill line, outdoor kitchen sink and dishwasher, outdoor shower, irrigation tied to mains, occasional outdoor bath spout.
• Final compliance pack, QBCC Form 4, gas compliance, hydrostatic test, HWU warranty, as-built drawings, premium documentation pack typical for high-spec builds.

What is genuinely different about canal-front new builds:

1. Outdoor scope is 30-50% of the plumbing job. Pontoon water, pool top-up, irrigation, outdoor kitchen, outdoor shower, occasional outdoor bath. All add up to a significant share of the total spec versus standard inland where outdoor is usually one hose tap and one irrigation line.
2. Pontoon fresh-water tap, marine-grade fittings. Brackish canal exposure plus saltwater spray from the boats means standard chrome-plated brass fails fast on the pontoon. Marine brass or 316 stainless, with the supply line properly bedded against UV exposure.
3. Pool top-up auto-fill, we run a dedicated cold water supply to a pool top-up valve with backflow prevention. Optional float-controlled auto-top-up, popular spec.
4. Premium brassware spec. Phoenix Vivid Brushed Brass, Sussex Voda, Astra Walker, Gareth Ashton across the home. Sometimes with bespoke spec sheets where each bathroom has different tapware to differentiate the rooms.
5. Client expectations on finish are 2-3x inland-suburban. Centres need to be exact, alignment needs to be perfect, every detail visible.

Working with the builder and designer: canal-front builds usually involve a custom builder and often a separate interior designer specifying tapware and fittings. We coordinate with both and we will push back at quote stage if the specified fitting will not work in the proposed location.
