January is often the coldest time of the year. When temperatures drop suddenly, home plumbing can face real risks—frozen lines, unusual pressure, cracked joints, and leaks, so as to the water filters placed in the outside. Most “water disasters” don’t happen because the issue was huge at the start, but because it was noticed too late, handled incorrectly, or never prevented in the first place. This short guide covers the most important steps—so you can reduce risk without overcomplicating your life.

每年1月往往是一年里最冷的阶段，温度一旦突然下降，家里的管道就可能面临冻住、水压异常、接口开裂、漏水等风险, 安装在室外的净水器也会遭遇类似情况。很多“水灾”其实不是大问题变成大事故，而是因为发现得晚、处理不对、没有提前预防。这篇我们就用一篇短文，把最关键的做法讲清楚——让你在不折腾的前提下，把风险降到最低。

Why Pipes & Filters Crack More

Easily in Winter

Where there’s water, freezing is possible. When water freezes, it expands—so the weakest points are usually connectors, elbows, valves, and exposed sections as well as the plastic filter canisters, not the long straight pipe runs.

管道里有水，就有结冰的可能。水结冰体积会膨胀，最容易出问题的往往不是整段管子，而是：接口、弯头、阀门、外露段以及塑料的滤瓶。

Pay extra attention to these situations:

• Pipes inside kitchen/bathroom cabinets, shaded corners, or along exterior walls

• Balconies, window areas, utility rooms, corridors—drafty, colder zones

• Homes left unused for long periods, or when you’re traveling

尤其是这些场景要格外注意：

• 厨房/浴室柜体里、背阴的角落、靠外墙的位置

• 阳台、窗边、设备间、走廊等通风又低温的地方

• 长时间不开水、家里没人住、短期出差/旅行

If a pipe and filter bursts, the damage is not simply just fixing one pipe. It can affect floors, walls, furniture—and sometimes even neighbors below. Preventing it early is always the easiest and cheapest path.

一旦冻裂漏水，损失往往不是“修一根管”/换一个净水设备这么简单，而是牵扯到地板、墙面、家具，甚至楼下邻居——越早预防越省心。

Top 3 Steps to Take

Before Cold Wave

Step 1: Insulate exposed pipes and plastic filters canisters

Any visible pipes, valves, joints or plastic canisters—especially on outdoor areas, balconies or near exterior walls—should be wrapped with insulation or protection coats. Think of it like a “winter coat” for your plumbing.

第一件：给外露管道做保温

能看到的外露管、阀门、接口、塑料滤瓶的地方，尽量用保温棉/保温管套包好，尤其是户外、阳台和靠外墙的位置。保温层就像“外套”，能明显降低结冰概率。

Step 2: Let warm air reach the pipes

On colder days, slightly open cabinet doors under sinks (kitchen and bathroom) so warm indoor air can circulate around the pipes. Many pipes get frozen simply because the cabinet space is cold and sealed.

第二件：让“暖空气”能到管道周围

厨房、浴室柜门在冷天可以适当打开，让室内暖空气流通到管道附近。很多冻管就是因为柜体里太冷、又完全不通风。

Step 3: Keep water flowing (short term)

During extreme cold alerts, letting a faucet run as a very small trickle can reduce freezing risk. This is best used for short periods—the real foundation is still insulation and airflow.

第三件：保持少量用水或流动（按情况）

极端低温时，适当让水保持轻微流动（例如很小的细流），能降低结冰概率。这个做法更适合短时间低温预警，不建议长期一直滴水浪费；关键还是前两件的保温与通风。

If You’re Leaving Home

or If a Leak Happens

If you’re traveling or the home will be empty:

• Don’t set indoor temperature too low (basic heating helps protect pipes)

• Check for known weak points, older leaks, and uninsulated exposed sections

• If possible, ask a friend/concierge/property management to check occasionally

如果你要出差或房子短期空置：

• 不要把室内温度降得太低（保持一个基础温度更安全）

• 提前检查：阀门位置、是否有旧漏点、外露管道是否已保温

• 有条件的话，安排朋友/物业定期看一眼（早发现很关键）

If a pipe bursts or you see serious leakage:

1. Shut off the home’s main water valve immediately

2. Open indoor faucets to release pressure and drain remaining water

3. Contact property management/maintenance for repair

4. After repair, monitor water quality: a burst/repair can introduce silt, rust, and debris into the line. Filters may clog faster, so it’s worth checking whether your filter needs earlier replacement to maintain flow and filtration performance.

如果已经出现爆管/漏水：

1. 先关闭家中总阀（越快越好）

2. 打开室内水龙头泄压、排水

3. 同步联系物业/维修处理破裂点

4. 维修后建议关注水质变化：爆管维修可能带来泥沙、铁锈等杂质冲入管路，净水滤芯更容易被“突然冲脏”，需要评估是否提前更换，避免影响净水效果与流量。
