Tank or mains, bottled gas, storm tide streets: what changes a Redland Bay job

Redland Bay runs from rural land in the west and south to a bay foreshore, and council says some properties here use water tanks or gas bottles. That spread changes a hot water job, because the right repair or replacement depends on the supply and the ground as much as the model. We repair and replace gas, electric and heat pump units for homeowners, and look after rental properties for landlords and property managers. We are a family-run Redlands plumber and gasfitter. If your heater has failed or is on its way out, the notes below help you work out what to check, and what to tell us when you call.

Before comparing brands, work out three things about your block: where its water comes from, where any gas comes from, and whether council names your street for storm tide or flash flooding.

Council describes Redland Bay’s west and south as predominantly rural, while its southern catchment holds recent housing around lower Weinam and Torquay Creeks. With both here, and council saying some properties use water tanks or gas bottles without listing streets, find out what feeds your heater first. On a tank-fed block where no tap runs, check the tank and pump before blaming the heater; an empty tank needs a water delivery, not a new unit, so ask the carter whether the load comes from an approved council filling station such as 47-49 Orchard Road.

Council rates large areas of the south and west as high to very high bushfire hazard, and separately, in general service-disruption advice rather than a bushfire rule, tells residents to keep gas cylinders secure and maintained. Two distributor sources we read show no mains gas coverage for Redland Bay, so if your heater is gas, check whether bottles feed it and mention them when asking about a replacement; we handle gas fitting and appliance connections under licence L90908.

Near the bay, council names Banana Street, the Esplanade, Junee Street, Pear Street, Zipfs Road and Rocky Passage Road among coastal locations storm tide may affect. For flash flooding it names parts of School of Arts Road, Serpentine Creek Road, Hamilton Street and Pitt Street. That is no finding about any one address, but on or near those streets, look up your block’s flood or storm tide level, then talk to us about the mounting position. Serpentine Creek drains to the lower Logan River and the southern coastal strip to Moreton Bay, so tell us which side you are on. If creek or bay water reaches a gas unit, do not use it until a licensed gasfitter inspects it, as the Queensland Government requires for gas appliances.

Weak cold taps too may point to the street: a pressure-reducing valve on a Giles Road main in Redland Bay failed on the night of 19 October 2022, as council’s Redlands Coast Today reported in its 20 October update, with water loss or low pressure in parts of Redland Bay, Victoria Point and Coochiemudlo Island. The Giles Road failure was one dated event, not a pattern, but if hot and cold fade together, check council’s notices and ask a neighbour before buying a heater.

At the 2021 Census, 84.1% of Redland Bay households were families. The census does not measure hot water use, but with 13.8% lone-person households against 24.7% statewide, we infer several people may share a morning or evening peak, so tell us how yours uses hot water before settling on a size.

Hot water problems to check first

  • Every tap drops out at once

    Council reported a water main burst at the corner of Peel and Dart Streets, Redland Bay, on 21 October 2022, and a burst at the same corner on the morning of 22 October, with water restored each time. Those are dated examples, not a pattern, but they show a sudden loss of water can be a burst in the street that council fixes, with no fault in your hot water system. Check council’s notices and ask a neighbour first. If the street has water and your hot taps still do not run, call us about a hot water repair.

  • Weak hot water on a tank-fed block

    On tank supply, pressure depends on the layout: Rheem’s electric guide needs the tank base at least 1 m above the highest hot water plumbing if no pressure pump is fitted, and its heat pump guide calls for a pump if 200 kPa cannot be reached at the heater. The tank and pump arrangement can decide which unit suits, so a new heater alone may not fix the shower. Tell us you are on a tank when you call, since we handle rainwater tank services as well as hot water repairs and replacements.

  • Failed unit, unknown age or supply

    Council describes the Southern Redland Bay catchment as mainly rural, with recent urban housing in the lower Weinam and Torquay Creek catchments. With recent housing and rural land in that one catchment, neither a heater’s age nor its supply can be assumed from the suburb name. Read the unit’s data plate, note tank or mains and bottles or no gas, and give us those details when you call about a repair or replacement.

  • No hot water after a storm

    Council calls severe thunderstorms Redland Bay’s most common natural hazard, and says power outages can occur during severe weather, flooding or bushfire. A cold shower straight after a storm may be a power problem, not a failed heater, so a replacement could be money spent on the wrong thing. Check for an outage first, because Energex takes network fault reports on 13 62 62. If the power is on and the water stays cold, call us about a hot water repair.

  • Running out before the last shower

    At the 2021 Census, 68.0% of Redland Bay homes had four or more bedrooms against 38.8% for Queensland. An electric unit on Energex’s economy Tariff 31 gets 8 or more hours of supply, around 10pm to 7am, and those times can change. Energex lists simply using more hot water than usual among the causes of losing hot water on an economy tariff, alongside a faulty system or a receiver fault in the meter box. A like-for-like swap may suit a large household poorly. Tell us how many people use hot water and how many bathrooms run at once before you settle on a size. We replace units across gas, electric and heat pump.

  • Relief valve running at night

    Rheem’s 111/191 electric guide says some relief valve discharge is normal, while steady flows for long periods, often at night, may mean mains pressure sometimes rises above the heater’s design. The same guide treats more than a bucket in 24 hours as a sign of another possible problem, and warns never to fit a higher-rated relief valve as the fix. Note how much water comes out and when, then call us about it as a hot water repair.

  • Planning a gas upgrade without mains gas

    Australian Gas Networks’ availability check and Allgas’s March 2026 street list, the two distributor sources we looked at, show no mains gas coverage for Redland Bay. A gas unit here may need to run on bottled LPG, which changes how it compares with electric or a heat pump. Confirm the home’s actual supply before choosing a unit, as these lists change. We connect gas appliances under gas licence L90908.

Licences, base and what Google reviews say

Jim Monger Plumbing and Gas is a family-run plumber and gasfitter based at 3 Jordan Dr, Victoria Point, serving the Redlands, Logan and south-east Brisbane. We hold QBCC plumbing licence 15504687 and gas licence L90908, and you can check both numbers. Our Google rating was 4.9 from 100 reviews as of 28 October 2026. One 2021 Google review from a Redland Bay customer describes a new water main, with hot and cold water back to normal within the day as promised. That was a water main job, not a hot water system job. On hot water, one Google reviewer said a call saved them buying a new system they did not need, at $2600 by their own figure, and another praised a prompt quote on a replacement. Other Google reviewers mention using the team more than once, including for hot water installs. These are individual experiences, not promises about any one job.

Have four things ready when you call: tank or mains, bottles or no gas, your street, and how many people shower at the same time. Quotes are free and emergency calls are taken 24/7, so we can talk through the supply and the position before you commit to anything.

Frequently asked questions

Call 0418 871 269
How do I check my own block before choosing where a new unit goes?

Council’s creek flood maps show depth and extent for a 1% AEP flood, though they leave out overland flow. Peak storm tide levels come from a property enquiry on council’s Development.i site. We do not assess flood risk ourselves, so bring what those tools show and we can talk through the position.

Do you install heat pump hot water systems in Redland Bay?

Heat pump repairs, replacements and new installations are part of our hot water work. Rheem says heat pump efficiency rises with air temperature within the operating range, and the BoM’s closed Redlands HRS site recorded a mean July minimum of 8.2 C and maximum of 20.4 C, so ask how your model handles winter nights. Rinnai also expects heat pumps to run during the night, which is why the position matters.

Is water pressure high or low in Redland Bay?

No single figure answers that for one house; a gauge reading at the property does. Council’s zone map labels bulk control valves at Giles Road and two Serpentine Creek sites in this part of the network, but its flow and pressure report is not verified by field testing. At the low end, Rheem says true mains-pressure operation needs more than 350 kPa. At the top end, the 2022 edition of the Plumbing Code of Australia sets a 500 kPa maximum static pressure inside a building, apart from existing low-pressure gravity-only services, so a higher limit in a unit’s manual is not the only ceiling. Take that reading before you choose a unit, and give us the number when you call.

Does tank water affect a hot water warranty?

It can. Rheem’s heat pump guide warns that rainwater tank water in a metropolitan area is likely to be corrosive, and its warranty does not apply where pH is below 6.0 or chloride exceeds 250 mg/L. Read from council’s shaded zone map, Redland Bay appears to fall in the Heinemann Road zone, where 2024-25 monitoring recorded chloride of 20 to 58 mg/L and field pH of 6.5 to 8.28, but those are mains samples across the zone and say nothing about a tank. Terms vary by product, so mention your tank when replacing a unit and read the warranty for that model.

I manage a Redland Bay rental with a failed unit. What should I find out first?

Ask the tenant whether the property has a water tank or gas bottles, because council says some Redland Bay properties do and it changes the job. We handle plumbing maintenance for rental properties, so pass that on when you call.

Is a replacement just a straight swap?

Not always, because Queensland requires stored water to be heated to at least 60 C and delivered to taps at no more than 50 C, with a temperature control device on new and replacement systems. We install and maintain thermostatic mixing valves.
