Blocked drains are a common issue in commercial refrigeration systems, and if not addressed quickly, they can lead to leaks, ice buildup, foul odours, and even equipment damage. In a busy commercial setting – like a restaurant, café, or supermarket – keeping refrigeration units running efficiently is crucial. Fortunately, many drain blockages can be cleared with a few simple steps.
Why Do Drains Get Blocked?
Over time, dust, grime, food particles, and mould can build up in the drain line. In commercial environments, where refrigeration units run constantly and are often opened and closed throughout the day, the chance of a blockage increases. Regular cleaning and maintenance are the best way to prevent this, but even with a good maintenance routine, blockages can still occur.
Step 1: Flush the Drain with Water
The first and simplest way to tackle a blocked drain is to flush it with water. While it’s normal for a small amount of water to sit in the drain, running a larger volume through it can help dislodge and carry away built-up material. This method is effective for minor blockages and should be part of regular preventative maintenance on commercial units.
Pour the water slowly and check whether it drains away quickly. If the water backs up or drains very slowly, the blockage may be more severe and require further action.
Step 2: Use a Hose to Clear the Blockage
If water alone doesn’t clear the blockage, the next step is to use a hose or flexible tube to manually dislodge the debris. Carefully insert the hose into the drain line and push it through to break up any build-up inside. Once you’ve pushed the blockage through or removed it, flush the drain again with water to ensure it’s fully cleared.
This method is often all that’s needed to restore proper drainage in a commercial unit – especially those exposed to high levels of moisture, food particles, or dirt.
Avoid Using Chemicals
In commercial refrigeration, using chemicals to clear a drain is not recommended. Many cleaning agents can react poorly with the evaporator or other internal components, potentially causing corrosion or equipment failure. Unless you’re using a product specifically approved for refrigeration use – and you’re confident in how to apply it – it’s best to avoid chemical cleaners altogether.
