Caravan plumbing has its own quirks - 12V pumps, push-fit fittings, flexible hose runs, tanks that flex under load. A generic plumber will struggle with some of this.
Our workshop carries a full range of caravan-specific plumbing fittings, pumps, hoses and replacement tanks so most jobs can be started the day your van arrives.

Diaphragm pump diagnosis and rebuild, pressure switch replacement, full pump replacement and upgrades. Shurflo, Whale and major brands.
Patch and repair polyethylene tanks, replace cracked fittings, fix breather problems and restore leaking outlets.
Retrofit grey water tanks to older caravans. Designed to fit your chassis layout with proper outlet valves and breathers.
Inline filters, under-sink filtration, whole-of-van systems. Essential for travellers drinking bore water or uncertain town supplies.
Kitchen and bathroom tap replacement, shower head repairs, mixer valves, and all 12mm push-fit fittings in stock.
Hot water plumbing, isolation valves, pressure relief and tempering valves. Works alongside our gas hot water servicing.

Leak in the system or a failed pressure switch. We locate the source, repair or replace, and prove the system is fixed.
Blocked filter, failing pump, air in the lines or kinked hose. We diagnose with proper gauges rather than guessing.
Blocked breather, kinked fill hose, faulty level sender or restricted fill point. Quick fix once identified.
Tank cracks, loose fittings, failed valves or damaged pipes. Becomes serious quickly - book early.
Bacterial growth in the fresh tank. We flush, sanitise and install filtration to stop it coming back.
Worn cartridges, failing washers or cracked tap bodies. Repaired with caravan-specific fittings built for travel vibration.
If you are handy with a spanner and want to tackle a repair yourself, our St Marys parts shop carries a full range of caravan plumbing fittings, pumps, hoses and fixings.
Bring in your old parts for matching, or describe what you need over the phone. We will happily give DIY advice and help you find the right part.

Heading off on a long trip? Have the plumbing system pressure-tested before you go. A 15-minute check can catch a failing fitting that would otherwise drain your fresh water tank overnight 500 km from the nearest workshop.
A pump that runs continuously usually means there is a leak in the system, a failed pressure switch on the pump itself, or air in the lines. The pump runs because it cannot reach pressure. We trace the issue, fix the leak or replace the pump, and test the full system before handing the van back.
Yes, most tanks can be repaired rather than replaced. We patch polyethylene tanks, replace fittings, fix cracked outlets, and replace mounting hardware. If the tank is beyond repair we can source and install a replacement to suit your caravan layout.
Yes. We install inline caravan water filters, under-sink filter systems, and full whole-of-van filtration for travellers who rely on bore, tank or dubious mains water. Filter change intervals vary by system so we explain what you need to do and carry the replacement cartridges in our parts shop.
Yes. Many older caravans were built without grey water tanks, and national parks increasingly require them. We can retrofit a grey water tank suited to your chassis layout, including all plumbing connections to the sink and shower drains.
Yes, we carry a wide range of caravan plumbing fittings, taps, pumps, hoses, 12mm push-fit fittings, tank breathers and water heater parts in our St Marys parts shop. You can visit the shop directly, call us to check stock, or browse online at our parts store.
Pump cost varies by brand and flow rate - most replacement pumps suitable for caravans are between $150 and $350 for the pump itself, with installation typically under an hour of labour. We always provide a written quote before proceeding so you know exactly what you are paying.
Leaking tanks, failing pumps, low pressure or mystery drips - bring your van in and we will sort it out.
