OUR INTRODUCTION
Hay Plumbing Co is a family-owned Central Coast plumbing team with 5 years of hands-on experience, fully licensed and insured for residential work across Erina and nearby suburbs. We’re regularly on the roads around Terrigal Drive, The Entrance Road, and the Erina Fair area, servicing a mix of older homes, renovated brick houses, and newer estates.
In Erina, we commonly see blocked drains from tree roots, stormwater overflow after heavy rain, and leaks caused by ageing fittings or worn flexi hoses. Coastal conditions across the Central Coast can also speed up corrosion on external taps, valves, and exposed pipework. We focus on clear advice, tidy workmanship, and practical solutions that last.

COMMON SERVICES
Hay Plumbing Co provides a full range of residential plumbing services across the Central Coast, from urgent repairs to planned upgrades and renovations. The services below cover the most common plumbing jobs we handle. If you don’t see your specific issue listed, contact us and we’ll let you know how we can help.
Burst pipes, overflowing toilets, or sudden loss of water can’t wait. We provide fast triage and same-day support where possible, any time of day. If you need urgent help, use our emergency plumbing service for rapid attendance and clear next steps.
Slow sinks, gurgling toilets, and outside drain overflow often point to a deeper blockage, sometimes roots, grease buildup, or sand and silt. We’ll locate the cause and clear it properly to restore flow and reduce repeat issues via our blocked drain repair service.
No hot water, fluctuating temperature, or a leaking cylinder usually means a fault that needs quick diagnosis. We troubleshoot electric and gas units, replace failed valves where suitable, and advise on repair vs replacement through our hot water system repair service.

Running cisterns, weak flush, blockages, and leaking toilet bases waste water fast and can damage flooring. We repair internals, reseal where needed, and help prevent repeat clogs. For persistent issues, book our toilet repair service for a proper fix.
Dripping taps and hidden leaks can quietly spike bills and cause mould or timber swelling. We handle tap repairs, leaking mixers, pipe leaks, and water pressure issues with clean, practical solutions. Get it sorted with our tap and leak repair service.
If you’ve got damp patches, unexplained water use, or a suspected slab leak, guessing gets expensive. We use proven methods to narrow down the source and recommend the right repair approach. Start with our leak detection service to find the problem sooner.
NEED A PLUMBING SERVICE?
Gas issues need a licensed professional, whether it’s a new cooktop connection, a bayonet point, or a suspected gas leak. We follow safe testing procedures and provide compliant work for peace of mind. Arrange our licensed gas fitting service for safe installation and repairs.
Planning a bathroom upgrade in Erina? We help with plumbing rough-ins, fixture moves, drainage, and coordination-ready work so your renovation runs smoothly. Explore our bathroom renovation plumbing service for compliant, tidy installation support.
WHY LOCAL EXPERIENCE MATTERS
Choosing a local Central Coast plumber means faster arrival times and less waiting when something goes wrong. We know the main routes and how Erina connects to surrounding suburbs, which helps when you need same-day help. Local experience also means familiarity with common property layouts, older homes, renovated bathrooms, and newer builds and the plumbing infrastructure that supports them. Most importantly, you get clear communication, straightforward options, and a trusted team that relies on reputation in the area.

Erina homes often deal with blocked drains caused by tree roots, especially where older clay or aging PVC lines run near established gardens. Heavy rain can overwhelm stormwater systems, leading to pooling near grates, garages, or low points on the property. We also see hot water failures from ageing units and tempering valve issues, plus leaking taps and flexi hoses that wear out over time. Across the Central Coast, coastal air can accelerate corrosion on external fittings, especially where pipework is exposed or older hardware hasn’t been updated.

Hay Plumbing Co services the entire Central Coast region, providing fast response plumbing across coastal suburbs, residential estates and growing family areas.
