廁所、廚房、浴室嘅去水同時變慢或者唔流，代表堵塞喺主渠位置。
Multiple drains clog together at the same time (toilet, kitchen, bathroom) — blockage is in the main stack.
沖廁或者樓上用水時，水會從其他去水口反湧出來。
Water backs up from drains when flushing or upstairs uses water.
去水口傳出嚴重異味，即使開水沖都無法消除。
Foul odour from drain openings that doesn't go away even after flushing water.
聽到喉管有「咕嚕咕嚕」嘅氣泡聲，代表氣體無法正常排出。
Gurgling sounds in pipes — gas cannot escape properly.
主渠堵塞嘅特徵：(1) 個屋多個去水位同時淤塞（廁所、廚房、浴室都唔流）；(2) 水會反湧出來（特別係沖廁或者樓上用水時）；(3) 有異味從去水口溢出；(4) 聽到喉管有「咕嚕咕嚕」聲。如果有多個徵狀同時出現，應該立即聯繫專業師傅。
Main sewer drain blockage signs: (1) Multiple drains clog together (toilet, kitchen, bathroom all slow); (2) Water backs up when flushing or upstairs uses water; (3) Foul odour from drains; (4) Gurgling sounds in pipes. If multiple signs appear together, contact a professional immediately.
由 HKD 900 起（typical）。主渠堵塞需要專業設備（高壓水槍、電視鏡），師傅會上門檢查後確認實際收費，WhatsApp 書面報價，無隱藏收費。複雜個案（例如需要開挖地面、更換喉管）會事先說明收費。
From HKD 900 starting. Main sewer blockages require professional equipment (high-pressure jetting, CCTV); actual cost confirmed after on-site inspection, written WhatsApp quote, no hidden charges. Complex cases (e.g., excavation needed, pipe replacement) will be explained and quoted beforehand.
一般 1-2 小時完成。複雜個案（例如需要電視鏡檢測、深層淤塞、樹根入侵）可能要 2-3 小時。完工前會即場 retest 確保去水正常。
Typically 1-2 hours. Complex cases (CCTV inspection required, deep blockage, tree root intrusion) may take 2-3 hours. On-site re-test before we leave to ensure proper drainage.
唔建議 DIY。主渠堵塞需要專業高壓水槍設備，自行處理可能導致：(1) 污水溢出損壞裝修（地板、牆身）；(2) 喉管破裂（強力通渠棍可能損壞舊喉管）；(3) 化學劑危害（強酸通渠水會損壞喉管且釋放有毒氣體）。應立即聯繫專業師傅。
Not recommended. Main sewer blockages require professional high-pressure jetting equipment. DIY may cause: (1) Sewage overflow damaging property (floors, walls); (2) Pipe damage (heavy drain rods may damage old pipes); (3) Chemical hazards (strong acid cleaners damage pipes and release toxic fumes). Contact a professional immediately.
主要原因包括：(1) 樹根入侵（舊樓/獨立屋常見，樹根會從喉管接口生長進去）；(2) 紙巾/濕紙巾積聚（唔應該沖入廁所）；(3) 油脂凝結（廚房油滲入主渠凝固）；(4) 喉管老化塌陷（舊樓鐵喉/鋅喉腐蝕）；(5) 物件掉入（玩具、碎布、建築廢料）。
Main causes: (1) Tree root intrusion (common in old buildings/villas, roots grow into pipe joints); (2) Paper towel/wet wipe buildup (should not flush); (3) Grease solidification (kitchen grease enters main stack); (4) Aging pipe collapse (old cast iron/steel pipes corrode); (5) Foreign objects (toys, rags, construction debris).
可以。DrainFix 使用專業高壓水槍可以清除大部分樹根堵塞。如果樹根入侵嚴重導致喉管破裂，我哋會同你講清楚，可能需要喉管更換工程（會另外報價）。建議定期用電視鏡檢查，預防樹根破壞。
Yes. DrainFix uses professional high-pressure jetting to clear most tree root blockages. If roots have severely damaged the pipe, we will explain clearly and pipe replacement may be needed (separate quote). Recommend regular CCTV inspection to prevent root damage.
