Chemical drain cleaners: put the bottle down

A bottle from the supermarket is tempting when the shower won’t drain. Here’s why it rarely fixes the real blockage, and what to do instead.

Tell us

  • The drain. Toilet, shower, sink, laundry or the outside gully.
  • What it does. Slow, gurgling, overflowing, smelly.
  • How long. Since today, or on and off for months.
  • Access. Who can let us in, and who approves the job.

What they’re made for

Chemical drain openers use corrosive acids or alkalis to break down soft build-up such as hair and grease in a single drain. They do nothing for tree roots, wipes, silt or a pipe that has cracked or sagged, which are the usual causes of a blocked sewer line.

What they do to pipes

Excessive use of chemical drain cleaners can damage pipes. In an old earthenware line or a corroded joint, that’s the last thing it needs.

What they leave behind

When the chemical fails, the drain is still blocked and now holds a corrosive liquid. Tell us what you’ve poured in before we start, so we can work safely.

What to do instead

Stop running water into the drain. Check whether it’s one fixture or several, and look at the outside gully. Then call us with what you’ve seen: we confirm the visit and clear it with a jetter or a drain machine.

FAQ

Questions

Got another question? Call us and we’ll talk it through.

What helps you quote a drain job?

The property’s suburb, which drain is affected (a fixture inside, the outside gully or a stormwater drain), when it happens and any work done on it before. Tell us about access too, and who can approve the job.

Why is water coming up through the outside gully?

The overflow gully outside is there to let a blocked sewer spill outside rather than inside. Water at its grate usually means the main drain is blocked further down. Stop running water and call us.
