Maintenance for Commercial Kitchens

Maintenance for Commercial Kitchens

Goodflo staff and management aim to provide comprehensive solutions and services for commercial kitchens and their grease management. The hospitality, food service and food manufacturing sectors and associated support services are essential to our country’s infrastructure and economy, and all require a kitchen grease trap of some sort. We want to support you in offering servicing and maintenance for grease traps for your commercial kitchen.  

The following information and advice are intended as a guide to support you in keeping your kitchen drainage and grease management systems ready for service.

Grease Trap Checks 

If your kitchen has undergone closure for a significant amount of time, whether due to the Covid pandemic, had undergone refurbishment or had to close for health and safety reasons, there will have been little or no water running through your grease trap and wastewater drainage system during the closure period. For in-kitchen grease traps and grease removal systems, there may be a strong odour in the room as a result of accumulated waste and lack of use during the closure period.  

Ventilating the area and following simple tests will check the health of your kitchen grease trap and drainage system, disperse foul odours and help highlight any problems before your kitchen is back in operation.  


Step One

Grease Traps and Grease Removal Systems

Turn on the taps from the pot wash sink and other appliances that run through your kitchen grease trap or grease removal system (before switching the power back on) and run water for at least 3 minutes.  

This will ensure there is sufficient water in your grease trap or grease removal unit for it to operate effectively.  

Check to see if the water is slow to drain from the pot wash sink as this may indicate that the grease trap requires a service, or this could be a blockage or restriction in the pipework from the pot wash or after the grease trap. 


Step Two

Toilets and Hand Wash Basins

Run the water in a similar way to step one to test the wastewater discharge from toilets, hand wash basins and other wash-up areas in the building. This will help identify any restrictions in your wastewater drainage system and prime it for reopening. 


Step Three

Biological Dosing Systems

Check to see if there is sufficient dosing liquid, check batteries or switch the electrical supply back on. Most dosing pumps have a primer button and when this is pressed you will see liquid moving through the system. Check dosing timing settings as it may be necessary to re-set these if the system has been switched off or disconnected from the power supply.

Step Four

If in doubt, call 01926 334466 or Email to re-start your planned service maintenance or request a service visit.


Have you Closed Your Kitchen? Grease Management Made Easy with Goodflo 

Grease traps for commercial kitchens are designed to be in regular use and rely on the flow of water to function and remain free flowing.  

If they are left dormant for any length of time the fats, oils and greases may clog and solidify, and the food solids will settle and prevent flow. 

They can also give off a strong, foul odour. 

Ideally, get them professionally emptied and flushed through with clean water. This is the only way to ensure your kitchen drainage will function as soon as you return to trading. 

Contact our team to arrange this and let us know when you intend to resume trading. Make sure you get it planned and organised early for peace of mind.  

Get your kitchen grease trap and grease management systems professionally serviced.

Grease Removal Units (GRUs) – Turn Them Off – Get Them Serviced Before You Return to Trading

GRU’s have the same issues as grease traps but with additional complications.

They all have power supplies, make sure you turn them off or ensure they are checked regularly and have fresh water in them.

Get them professionally emptied and flushed through with fresh water.

Contact our team to arrange this before you intend to resume trading. 

  1. Turn their power off
  2. Get them professionally serviced and flushed through
  3. Contact us for support

Before you return to normal kitchen activity you will need to turn the power on for at least 24 hours.

Increased Drainage Blockages 

Drains and sewers usually have much larger flows of wastewater through them than what they experience during a closure. These larger flows are effective at moving and clearing their contents.  

We expect the lack of flow to result in more sewer blockages than normal as the higher wastewater flow resumes when you return to normal trading. 

When you know you are going to resume trading, we recommend you test your flow in advance, this may be the difference between beginning trading and further delay.
