The problem in Adelaide, SA
Adelaide's mains water runs moderately hard — around 95 mg/L on the metro average, higher in the northern and western suburbs — and the mineral scale it deposits inside pipework gives hair and grease something to snag on. Once a film of organic build-up settles in, the tell-tale drain smell follows, even in Adelaide's relatively dry air.
The DRAINZAP approach
DRAINZAP clears the organic side of the problem with advanced clean chemistry (peracetic acid generated in-situ). The foam works its way through scale-roughened pipes, dissolving the hair and grease deposits that hard water helps trap — without caustic soda or sulfuric acid, and without harming your plumbing. Science-led. Powered by nature.

About DRAINZAP
DRAINZAP clears slow or smelly drains with a powerful, innovative formula that dissolves hair, soap scum, and grime within the hour — or leave it overnight for the best result on heavy build-up — without burning pipes, and gentler on your plumbing and the environment than caustic products. No caustic chemicals. No harsh odours. Just a deep, natural clean that keeps water flowing freely and odours away.
How to clear a blocked shower or sink drain
Pour a dose into the drain, add warm water and let the effervescent foam expand through the pipework — dissolving hair, soap scum and organic build-up within the hour (leave overnight for heavy build-up). Use monthly to keep drains flowing and odour-free.
Septic-safe drain cleaner — no caustic chemicals
DRAINZAP clears the same organic blockages caustic products target — without the hazard. Safe for pipes, plumbing, fittings and septic systems.

DRAINZAP FAQs
Will it clear a fully blocked drain?
For most organic blockages (hair, grease, soap scum, food waste) — yes. For solid foreign objects (a toy, a cotton bud stuck sideways) — no, nothing liquid will. For a drain that's been slowly building up and finally stopped: give DRAINZAP one hour, leave overnight if possible for maximum effect. Save the plumber callout.
Is it safe for my pipes?
Yes. DRAINZAP is a clean chemical formulation, not caustic. When activated with water it generates thick foam, coating pipework internals and dissolves greasy residues, hair, organic waste and destabilises biofilms. It won't corrode PVC, copper, brass, or stainless steel. Unlike chemical drain openers, you can use it as often as you need without damaging seals or pipe walls.
Is it septic safe?
Yes — fully septic safe. It clears the same organic blockages caustic products target — without the hazard, or the damage to fittings and plumbing. Most chemical drain openers kill the bacteria that make your septic system work. DRAINZAP does not.
How often should I use it?
For maintenance (preventing blockages or bad odours): once a month. For a slow drain: one dose and repeat when the problem arises again. For a bad blockage: one dose, leave overnight.
Will it get rid of the smell?
Yes. Drain smells are primarily caused by organic buildup (fats, oils, grease, hair, food particles) and "biofilm" — a slimy layer of bacteria that grows on the pipe walls, which emits gases as it breaks down waste. DRAINZAP digests that buildup, so the smell doesn't come back the next day like it does with bleach.
Adelaide questions, answered
Does Adelaide's water actually make drain blockages worse?
It contributes. Moderately hard water (~95 mg/L metro average) deposits mineral scale inside pipes, and that rough surface snags hair and grease more readily than smooth pipework. The organic build-up is what smells — DRAINZAP targets exactly that layer.
Can I use DRAINZAP in both the kitchen and bathroom?
Yes. The foaming action works through kitchen pipework carrying grease and food residue as well as bathroom drains carrying hair and soap build-up. Use one dose per drain and let it work before rinsing.
