Top Causes and Fixes for Commercial Blocked Drains

Blocked drains can be very messy, especially in a commercial kitchen or bathroom with high traffic.

Restaurant, cafe, hotel and public facilities need to reliably meet a higher volume of use. A blocked sink or flooded shower is unpleasant and inconvenient, but it can also cause a serious health hazard and shut operations down.

In this article, we discuss some of the common causes of blocked drains in commercial kitchen and bathrooms, and how to fix and prevent them in the future.

 

What Are the Signs of a Blocked Drain?

There are a number of early warning signs that you might have a blocked drain. These include:

  • A sulfur-like smell
  • Gurgling sounds coming from the drain
  • Overflowing plumbing fixtures
  • Drips, puddles and wet floors
  • Slow-draining basins
  • Changes to water pressure

Knowing these symptoms will help you identify issues before a serious problem develops.

 

 

What Problems Does a Blocked Drain Cause?

Blocked kitchen and bathroom drains are not only disruptive, they can lead to persistent and costly problems. Some of these include:

  • Unpleasant odours
  • Stagnant water, which attracts insects and pests
  • Water stains on your walls and ceilings
  • Excessive water bills caused by leaks
  • Sewage discharge on your property
  • Broken or burst pipes
  • Flooding

 

How Can I Prevent A Blocked Drain?

Many drainage problems can be avoided with regular preventative maintenance. Here we take a look at three of the top causes of blocked drains and the best ways to prevent them.

Grease

Problem

Oil might be a liquid, but it’s not ok to pour it down the sink. The build-up of grease from cooking oils is a common cause of clogged pipes, slow drains and water backup. The grease and lard in oil solidify as they cool, building up inside the drain and attracting more grime.

Solution and Prevention

Never pour oil down the drain. Place oil into a container and throw it away in the bin or phone a professional oil removal service. Sluice the drain at least once a week with 2–3 litres of boiling water to prevent build-up. If you have a grease trap, make sure you clean it every 4–6 weeks.

Food scraps

Problem

Many people throw food scraps down the drain without considering the impact it can have on their pipes. Food scraps get stuck and block your drain, but they also grow bacteria and mould, producing a sewage-like smell.

Solution and Prevention

Use a sink strainer to catch large residue and debris that could contribute to a blockage. Scrape food off plates into a bin or compost before rinsing in the sink. Never tip coffee ground down the sink. Coffee granules don’t break down in water and will clump together to clog your pipes.

Hair

Problem

Hair accumulates in bathtubs and showers, trapping soapy residue and skin particles in the drain to create an impermeable clump. Even small hairs from shaving a beard can collect on the pipe walls and build up slowly.

Solution and Prevention

Regular removal of hair from the drain is key. Put on gloves, remove the grate, and pull out any hair to prevent build-up. Brush your hair over the bathroom floor rather than in the shower, so you can sweep it up. Replace pop-up basin wastes with standard fittings to encourage more free-flowing drainage.

 

How to Fix a Blocked Drain

There are some simple things you can try to fix a blocked drain. Start by pouring several litres of boiling water down the sink. Use a plunger and then pour through more boiling water.

To correctly use a plunger, place the cup over the entire drain opening and cover the lipped rim with water. Push the plunger up and down to create suction and push the clog down the drain. If the drain is still blocked, use a chemical drain cleaner or, for a more environmentally friendly option, a mixture of baking soda and vinegar.

 

Quick tip to fix a smelly sink

Have you noticed an unpleasant smell from your sinks on dry, windy days? This is caused by wind running over the top of the pipes, sucking water out of the traps. When the water level drops, smells from the sewer rise. To stop the smell, run your taps or showers for five seconds and flush the toilets to top up water in the drains.  

 

When Should I Call a Plumber For a Blocked Drain?

Despite the best DIY intentions, there are times when you need to call a professional. A qualified plumber has the expertise and sophisticated equipment to handle chronic and repeated blockages. Using electric eels (drain snakes), high-pressure water jetters and CCTV cameras, a plumber can locate and eliminate blockages caused by oils, food and hair, as well as:

  • Foreign objects, like cotton balls and buds, jewellery, bottle tops and small children’s toys
  • Faulty installation with insufficient fall for waste transfer
  • Cracked, damaged or broken pipes.

Your plumber will clean the blocked drain thoroughly and identify any issues that might cause long-term or future damage. For structural issues, the only corrective measure may be to re-lay sections of the pipe.

    We cannot fault Tony and the team at Emu Plumbing. We had a very complex reline of a long combine sewer that had plagued us for decades.

    I moved into a new unit to find no water was flowing through the pipes. My property manager sent Eric from Emu Plumbing who fixed the matter quickly.

    Someone turned off my water supply last night as water from my unit was leaking downstairs into the foyer! Along came Eric who again fixed the problem of my laundry taps and he even left ‘who gives a crap’ toilet paper. Fantastic!!

    Prompt and excellent service from your company – Eric was polite and efficient.

  • “They did a very thorough, excellent job, with photographic evidence, were very reasonably priced and very professional”

    I needed to call an emergency plumber on a Saturday afternoon for issues at the office where I work in Kingsford Smith Drive in Eagle Farm. I called two local after-hours plumbers without success. Emu answered on the first ring although already busy with a job down the road. They estimated they would be finished with the current job and would be at the office by 4.30 pm which they were. They did a very thorough, excellent job, with photographic evidence, were very reasonably priced and very professional/ I would highly recommend them and use their services again without hesitation.

His worker, Niles was very professional, thorough and lovely. Issue was fixed and all my gas equipment around the house was brought up to compliance.
