Q3｜通水管或通馬桶通常要多少錢？
費用會依堵塞位置、異物種類、管線深度、是否需要拆卸設備，以及是否使用管內視鏡或高壓水刀而不同。永正會先了解問題，並依現場條件說明處理方式與報價。
How much does drain or toilet unclogging cost?
Pricing depends on the blockage location, material, pipe depth, disassembly requirements, and whether CCTV inspection or hydro jetting is needed. The service method and quotation are explained according to the actual site conditions.
Q4｜馬桶塞住可以先使用吸盤或通管藥劑嗎？
一般輕微衛生紙堵塞可先嘗試吸盤；若懷疑布料、濕紙巾、玩具或其他異物掉入，建議停止沖水並安排檢查。不要混用不同通管藥劑，以免造成化學反應、噴濺或管材損傷。
Can I use a plunger or drain chemicals first?
A plunger may help with a minor toilet-paper clog. If fabric, wet wipes, toys, or other objects may be involved, stop flushing and arrange an inspection. Never mix drain chemicals because they may react, splash, or damage the pipe.
Q5｜為什麼通完沒多久又堵塞？
常見原因包括異物未完全取出、管壁油垢或硬化沉積仍在、下游共用管堵塞，以及管線破損、錯位或坡度異常。需要依再次堵塞的時間、排水反應與管內狀況判斷，不宜直接假設是同一個原因。
Why does a drain become clogged again soon after cleaning?
Possible causes include remaining foreign objects, grease or hardened deposits, a downstream shared drain blockage, or structural issues such as damaged, misaligned, or poorly sloped pipes. A new inspection is needed to identify the actual cause.
Q6｜高壓水刀和一般通管有什麼不同？
一般通管通常以打開堵塞點、恢復排水為主要目的；高壓水刀則利用高壓水流沖洗管壁附著的油垢與沉積物。是否適合使用水刀，仍需依管材、管徑、管況與堵塞原因評估。
What is the difference between hydro jetting and conventional drain cleaning?
Conventional drain cleaning mainly opens the blockage to restore flow. Hydro jetting uses high-pressure water to remove grease and deposits from pipe walls. Suitability depends on the pipe material, diameter, condition, and cause of the blockage.
Q7｜什麼情況需要使用管內視鏡？
當排水反覆堵塞、堵塞位置不明、懷疑異物、樹根、破損或管線錯位，或需要確認清洗前後管況時，可評估使用管內視鏡。影像能協助判斷，但仍需搭配現場水流與管線走向分析。
When is a CCTV pipe inspection needed?
CCTV inspection may be recommended for recurring clogs, unknown blockage locations, suspected foreign objects, roots, damage, or misalignment, and for reviewing pipe conditions before or after cleaning.
Q8｜餐廳截油槽多久需要清洗一次？
沒有所有餐廳都適用的固定週期，應依每日出餐量、油脂使用量、食物殘渣、槽體容量與水位變化安排。若出現異味、水位升高或排水變慢，代表不宜再延後清洗。
How often should a restaurant grease trap be cleaned?
There is no single schedule for every restaurant. Cleaning frequency depends on meal volume, grease use, food solids, trap capacity, and water-level changes. Odor, a rising water level, or slow drainage are signs that cleaning should not be delayed.
Q9｜截油槽清洗後，排水仍然很慢怎麼辦？
截油槽與後端排水管屬於不同處理範圍。若油脂已穿過截油槽並附著在後端管壁，清槽後仍可能排水緩慢，需要再檢查後端管線並評估高壓水刀或其他處理方式。
What if drainage remains slow after grease trap cleaning?
The grease trap and downstream drain line are separate service areas. If grease has accumulated on downstream pipe walls, the line should be inspected for hydro jetting or another suitable method.
