DRAINZAP — Unblocks & deodorises drains

Frequently asked questions

Quick answers to the questions we hear most.

• 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.
