Licensed NSW plumbers · Local Northern Rivers team · 5-star rated

Maybe the tea tastes a little off. Maybe your hair feels harsh after a shower. Maybe there's brown in the toilet bowl no matter how often you clean it. Town water in the Northern Rivers meets safety standards - but it carries sediment, chlorine, and minerals that change how everything in your house feels. Filtered water sorts it.
Tea, coffee, cooking water: they shouldn't taste like the pool.
Dry hair, irritated scaly skin & harsh-feeling showers.
Toilet bowls, taps, & basins discolouring no matter what you scrub with.
White crust building up on the element within weeks of cleaning.
Indoor plants drying out & browning faster than they should.
Washing machines, fridges, dishwashers & hot water systems clogged with sediment.
We install all three. Each one's designed for a different kind of home & a different kind of concern.
Under-sink drinking water filter. Best for renters, smaller households, or anyone who just wants better water in the kitchen.
Whole-home filtration on your incoming water main. Best for homeowners, families, and wellness-focused households.
Whole-home filtration plus dedicated drinking water. Best for premium homes, larger families, and homes that want everything covered.
Prices are for standard installs. Mini-stops or a premium filtered-water tap (if you want one) are quoted on the call, we'll never surprise you with hidden costs.
Tier 1 install over 36 months. Less than two coffees.
A quick form. Postcode, what's bothering you about your water, a couple of photos under your sink. Takes 90 seconds.
Usually within a few hours. We talk through what's bothering you, recommend the tier that fits, and answer every question you've got.
If you're happy, we lock it in. Same-day finance approval. Small deposit to book your install.
Usually within two weeks. Tier 1 in an afternoon, Tier 2 in half a day, Tier 3 in a single day.

It meets the Australian Drinking Water Guidelines - so it's safe. But it still carries chlorine, sediment, and minerals that change the way water tastes, feels, and behaves in your home. Filtration handles what the council doesn't.
No, not noticeably. Whole-home filters are designed for full house flow.
You own it. Finance lets you spread the cost - but the equipment is yours, day one.
