Commercial Fryer Oil Not Draining
Here's what typically causes this, and why an on-site diagnostic — not a phone guess — is what gets you an accurate estimate.
Clogged Drain Valve
Food debris blocking the drain line.
Valve Mechanism Stuck
Handle or internal valve component worn or seized.
Filter System Issue
Built-in filtration pump or line blockage.
Why diagnosis matters: A symptom like this can trace back to several different root causes, and the fix — and its cost — depends entirely on which one it is. Roxly doesn't quote a repair price over the phone based on a symptom alone: a technician inspects the equipment on site, tests the likely components, and confirms the actual cause before giving you a firm estimate. That's what makes the quote accurate instead of a guess you find out is wrong after the work starts.
Is this a safety issue?
Hot oil that won't drain properly can be a burn hazard — worth having it looked at rather than forcing it.
Can this be prevented?
Regular filtering and cleaning per manufacturer schedule reduces buildup that causes this.
