In a restaurant the drainage causes more trouble than the supply. Fat, grease and food solids build up until a line backs up into the kitchen, and that is a closure risk rather than an inconvenience.
Work is scheduled between services or overnight. Wider scope at Leak Detection Cape Town.

- Grease-laden drain lines, narrowing until they back up under load.
- Grease traps that are undersized, overdue for servicing, or leaking at the lid seal.
- Floor gullies and channel drains with failed seals, letting water under the screed.
- Wet area waterproofing under a floor washed down daily.
- Appliance connections on dishwashers, combi ovens and ice machines, under constant load.
- Hot water demand that hides a leak inside a genuinely large consumption figure.
Health Inspection Exposure
A leaking or backing-up drain in a food preparation area is a compliance problem as much as a plumbing one. Standing water, foul odour and a failed floor seal are exactly what an inspection flags. Keep the CCTV footage and the service records for the grease trap; they are the evidence that the issue was identified and dealt with.

Jetting clears a grease line properly; rodding punches a channel through it that closes again within weeks. On a kitchen line, pay for jetting and a camera afterwards to see what caused it.

Frequently Asked Questions
Our kitchen drain keeps backing up. Why does clearing it not last?
Because clearing treats the symptom. Repeat blockages in the same line mean a physical cause: grease build-up on the pipe wall, a belly holding water, or a cracked section catching solids. A camera survey finds it.
Can the work be done without closing?
Detection and most drainage work is scheduled overnight or between services. Larger repairs may need a closed period, which is another reason to locate the defect precisely before committing.
How often should a grease trap be serviced?
It depends on covers and menu, but under-servicing is the most common cause of kitchen drain failures. Keep the service records, since they are also what an inspection will ask to see.
