Can detergents cause drain problems?

Detergents are a staple of household cleaning, from removing persistent stains in the weekly wash to keeping surfaces clean around the kitchen. But a recent trend encouraging the use of detergents for unblocking drains has had the opposite effect.

It seems logical that chemicals that specialise in removing dirt would also help with removing obstructions in drains, but this can actually cause more harm in the long run.

Why don’t detergents in washing machines block drains?

Detergents are definitely capable of blocking drains when used in washing machines, but if you adhere to the recommended amount, it’s unlikely you’ll ever face this issue. Washing machines also heavily dilute the detergent, which your sink isn’t able to do as effectively.

The problem is more common with powdered detergents, which are commonly used in online trends. These will fizz up and look attractive in a video but will leave a nasty trail of residue behind in the drain.

This residue will then catch other debris, like hair or crumbs, and is especially bad when combined with fats and oils. The detergent won’t dissolve these away, but will instead form a viscous sludge that is even harder to remove.

Older plumbing systems may also be susceptible to chemical damage, eroding pipes and causing even greater problems.

Solutions for blocked drains

If you suspect a blocked drain – indicated by water pooling in the sink, a foul smell, or unusual sounds – don’t depend on DIY trends from social media that prioritise video views over practicality.

The best way to solve drain problems is to first locate them via a CCTV drain survey. During this process, a small camera is inserted into the drain, relaying video footage of the issue. From here, a precise operation can be carried out to remove the blockage without causing major disruption.

You can find services for a CCTV drain survey Northampton online, such as Wilkinson Environmental.

The most common causes of blockages are fatbergs or other debris that has accumulated. Detergents will only add to this buildup, so your best bet is to get in touch with a professional.
