HK restaurants face a different drain problem from residential: daily grease + food debris volume overwhelms passive prevention. A typical mid-tier HK restaurant kitchen needs grease-trap service every 2-4 weeks, plus emergency dispatch during the 11am pre-lunch and 5pm pre-dinner windows when blocks must clear before service.

DrainFix HK serves restaurants on monthly contracts (HKD 800-1,500/visit) with priority dispatch built in. We currently serve mid-tier HK private kitchens, dim sum, hotpot, and bar-restaurants across Sham Shui Po, Mong Kok, Causeway Bay, Wan Chai.

What's included in a monthly grease-trap contract

🛠️ Full grease trap pump-outManual or pump-assisted complete clearing — not the "scrape the top layer" shortcut some vendors do.

📷 FEHD photo documentationBefore / after photos at each visit. Useful for FEHD self-audit + brand hygiene standards.

⚡ 1-hour emergency responseMonthly contract = priority queue. Block at 11am pre-lunch? We're there in 60 min vs. 2-3 hr for one-off calls.

🧾 Net 30 corporate APSingle monthly statement, ready for AP. Not "cash on the day".

📊 Quarterly deep-clean optionOptional quarterly add-on for full kitchen drain stack flush. HKD 1,500-2,500.

🚐 Multi-location pricingChain restaurants: HKD 700/location for 5+ locations. Single AP, single QC standard.

What we DON'T do (and why this protects your bill)

No water plumbing — taps, fittings, pipe replacement require licensed 水喉匠. We refer you to a licensed plumber if needed.
No mystery surcharges — pricing on this page is what you pay. After-hours surcharge is HKD 200 for residential, HKD 300-500 for commercial pre-disclosed.
No "while we're here" upsells — if we find a separate issue, we photo it + quote you separately. You decide whether to authorize.
No long-term contracts you can't exit — monthly contracts are month-to-month, cancel anytime with 30-day notice.

Why we focus on drains only (and why that's good for you): HK 水喉舖 (full plumbers) carry licensing overhead that gets passed to you. We focus exclusively on drain unblocking + grease traps — no plumbing modifications. Lower overhead = your contract HKD 800-1,500/visit instead of HKD 1,500-3,000+ from a full-service vendor.

FEHD compliance + hygiene rating

HK FEHD inspections increasingly check grease-trap maintenance frequency. Our photo documentation at each visit covers:

Before / after grease level measurement
Date + time stamp
Equipment used (pump model + capacity)
Disposal compliance (where the grease went — licensed waste handler reference)

This is the documentation FEHD inspectors look for. It also serves as defensible record if hygiene rating is ever questioned.
