单杆混合龙头的结构比传统双把手龙头简单，但 10 年的使用年限意味着你可能会遇到一些麻烦。**最可能的原因是陶瓷阀芯磨损或水垢卡滞**，漏水点在出水口，刚好指向这个问题。好消息是这属于可以自己动手的维修；坏消息是 10 年的龙头，阀芯型号可能不好找，甚至阀体内部已经腐蚀。

### 🛒 采购清单（在葡萄牙五金店怎么说）

核心要买的是**陶瓷阀芯**。葡萄牙语叫 **cartucho cerâmico**。如果你不确定型号，最稳妥的办法是拆下旧的带去店里比对。

| 物品 | 葡萄牙语名称 | 大概价格 |
|------|-------------|---------|
| 陶瓷阀芯（单杆混合龙头用） | **Cartucho cerâmico para torneira monocomando** | 8–35 €  |
| O 型圈套装（备用） | **Kit de o-rings** | 3–6 €  |
| 硅脂润滑剂 | **Lubrificante de silicone** | 5–8 €  |
| 白醋（除水垢用） | Vinagre branco | 家里可能有 |

进店可以直接说：*“Preciso de um cartucho cerâmico para uma torneira monocomando que está a pingar.”* 把旧阀芯给店员看，他们会帮你找兼容的。带上手机拍下龙头品牌型号更好。

**工具**：可调扳手（chave ajustável）、内六角扳手套装（chaves Allen，通常是 2.5mm 或 3mm）、平口和十字螺丝刀、一块布堵住下水口（防止小零件掉进去）。

### 🔧 维修步骤

**第一步：关水。** 找到洗手盆下方的角阀（**torneira de corte**），顺时针拧紧。然后打开龙头，把管道里的余水放干净。

**第二步：拆手柄。** 撬开手柄顶部或侧面的红蓝装饰盖（用平口螺丝刀轻轻撬），露出内六角螺丝。用对应的内六角扳手拧松螺丝（**不要完全拧出来**），然后向上拔出手柄。如果很紧，可能是水垢卡住了，轻轻左右晃动再拔。

**第三步：取出阀芯。** 现在你会看到一个黄铜或塑料的固定螺母/卡环。用可调扳手逆时针拧松它，取出旧阀芯。**注意阀芯底部的定位凸起方向**，拍张照片再拿出来。

**第四步：检查与清洁。** 看看旧阀芯的陶瓷片有没有裂纹或划痕。如果只是水垢，把它泡在白醋里 15–20 分钟，用旧牙刷清洁后试试能不能恢复。同时用手指或软布清洁龙头阀座内部，确保没有水垢碎屑残留。

**第五步：安装新阀芯。** 在阀芯的 O 型圈上涂一点硅脂（不要用凡士林）。把新阀芯按原来方向放入，确保底部的定位凸起对准阀座的槽。拧回固定螺母，**手感紧了就行，不要猛拧**，过度拧紧可能压裂陶瓷片或损坏螺纹。

**第六步：装回手柄，开水测试。** 慢慢打开角阀，先观察手柄根部有没有渗水。然后打开龙头，切换冷热水，关上后观察出水口是否还滴。如果手柄转动生硬，可能是阀芯没放正或螺母拧太紧。

### ⚠️ 什么时候该停手叫水管工

做到以下任何一步遇到问题，就别硬来了：

- **关水后龙头还在出水**：说明角阀坏了或者关错了，你无法安全作业，需要水管工处理上游阀门。
- **拆开发现阀体内部螺纹有绿色或白色腐蚀**（铜绿/水垢堆积严重）：10 年的龙头，阀座可能已经损坏，换阀芯也封不住，这种情况换整个龙头更划算。
- **取出阀芯后发现底部定位槽磨损或开裂**：这是阀体损伤，不是换阀芯能解决的。
- **换了新阀芯装回去，还是滴**：如果确认型号对、安装正、螺母紧度合适，仍然滴，说明问题在阀体本身。试两次不行就打电话。

如果最终需要换整个龙头，里斯本地区水管工收费大概在 **80–120 €** 含人工。你自己买一个中档单杆混合龙头大概 40–100 €，可以问水管工能否只收安装费。

## English translation of the substance (by the operator's assistant; not part of the output)

A single-lever mixer is simpler than a two-handle tap, but ten years means some trouble. Most likely a worn or scale-jammed ceramic cartridge; a drip at the spout points to it. Good news: DIY-able; bad news: the cartridge model may be hard to find, and the body may be corroded inside.

**Shopping list (what to say in a Portuguese hardware shop)** — the core part is the ceramic cartridge, "cartucho cerâmico"; if unsure of the model, take the old one to the shop. Table: "Cartucho cerâmico para torneira monocomando" 8–35 € · "Kit de o-rings" 3–6 € · "Lubrificante de silicone" 5–8 € · white vinegar for limescale. Say: "Preciso de um cartucho cerâmico para uma torneira monocomando que está a pingar." Show the old cartridge; photograph the brand/model. **Tools:** adjustable wrench (chave ajustável), Allen keys (chaves Allen, usually 2.5 or 3 mm), flat and Phillips screwdrivers, a cloth over the drain so small parts do not fall in.

**Steps** — 1. Shut the water: find the angle valves under the basin ("torneira de corte"), turn clockwise; open the tap and drain the line. 2. Remove the handle: prise off the red/blue cap, loosen (do not fully remove) the Allen screw, pull the handle up; if stuck by scale, rock it gently. 3. Remove the cartridge: loosen the brass or plastic retaining nut anticlockwise with the adjustable wrench; note the orientation of the locating lugs, photograph, lift out. 4. Inspect and clean: check the ceramic discs for cracks; if only scale, soak in white vinegar 15–20 minutes and brush; clean the seat inside the body. 5. Fit the new cartridge: silicone grease on the O-rings (not Vaseline); same orientation, lugs into the slots; retaining nut hand-tight, do not force — over-tightening can crack the ceramic or the thread. 6. Refit the handle, open the angle valves slowly, watch the base of the handle, run hot and cold, close and watch the spout; a stiff handle means the cartridge is not seated or the nut is too tight.

**When to stop and call a plumber** — water still runs after shutting off (angle valve broken or wrong one; you cannot work safely; a plumber must deal with the upstream valve); green or white corrosion on the body threads (seat probably damaged; a new cartridge will not seal; replacing the tap is better value); the locating slots at the bottom are worn or cracked (body damage, not fixable with a cartridge); a new cartridge still drips after two tries. If the whole tap must be replaced, a Lisbon-area plumber charges roughly 80–120 € including labour; a mid-range single-lever mixer costs 40–100 €; ask whether they will fit one you supply.

First read: substance is sound and complete - all six steps, the vinegar-soak option, prices, and the fullest reasoning about a corroded body - but it is in a language the user did not use. The Portuguese shop phrases are correct. Checks in the sheet.
