Common problems: less water output & more leakage incidents

冬季净水器和水管常见问题--出水少,漏水多

It is an unsatisfying experience to find that the water is not running from your tap on a cold winter morning, when all you need is a cup of coffee to wake you up. While water shutdown can happen, it is a rare instance, and the phenomenon should be blamed on the low temperature.

在一个寒冷的冬天早晨,当你需要一杯咖啡把你叫醒的时候,发现水没有从你的水龙头流出,这一定是一个令人不快的经历。虽然有可能是停水导致的,但这毕竟还是比较罕见的,所以我们认为这种现象应该归咎于气温过低。



Typically for purifiers with membrane filters, such as Ultra filtration, nano filtration and reverse osmosis purifiers, the water output decreases with the cold weather as low temperature makes the fine holes inthe membrane contract and lowers the filtration rate. As a result, less water will be able to pass through the membrane.

通常,对于带有膜过滤的净化器,例如超滤、纳滤或反渗透净水器,由于低温使膜上的细孔收缩并降低过滤速度,因此水输出量会随着寒冷的天气而减少,这就进一步导致通过膜的水量减少。


Another winter issue is water leakage. Pipe lines and filters in water purifiers are connected by a lot of joints, and the low temperature make the contacting parts not as effective as usual. This will cause water leakage to happen more easily, and the cold weather should be blamed.

另一个冬季问题是漏水。净水器中的管路和过滤器之间是通过大量的接头连接的,低温使得其接触部位的工作效率降低。进而导致漏水更容易发生,事实上这也应该归咎于寒冷的天气。

Different protections for different water filters

各类净水器防冻措施


1. For outdoor central water purifiers or softeners: when the temperature is less than 0 degree, it is usually suggested to move the systems into an indoor environment until the end of the cold days. In case this solution is not available, Greenwave can help providing you some protective coats for the machines, for a small cost.

对于室外中央净水器或软水器:当温度低于0度时,通常建议将系统移入室内环境,直到寒冷天气结束。如果没有这个解决方案,Greenwave可以帮助您为机器提供一些防冻外套,成本很低。



2. For indoor drinking water purifiers: the performance of the membranes and therefore the water output can both be affected by the cold weather. To avoid this issue, make sure the room temperature is above 0 degree, or if going out or not using it for a longer duration, shut down both the water source and power before letting all the water run out.

对于室内饮用水净化器:膜的性能和产水量都会受到寒冷天气的影响。低温会导致通过膜的水更少。为了避免这个问题,确保室温在0度以上,或者如果外出或长时间不使用,在让所有的水用完之前关闭水源和电源。




3. For the frozen water treatment systems, it is necessary to install it in a room with a temperature above 10 ℃ for at least 36 hours, to let the frozen system thaw completely. It could be put back on again after that. Please do not thaw the purifier with hot water or any heating system, as this will cause irreversible damage. For the defrozened system, please make sure that no part is distorted before you switch on the power and water source. If there is any water leakage or other abnormal occurrences during reuse, please stop using it and contact service people for necessary repairing.

当净水器结冰时:必须将其安装在温度高于10℃的房间内至少36小时,以使冷冻系统完全解冻。在那之后它可以再放回去。请勿用热水或任何加热系统解冻净化器,否则会造成不可逆转的损坏。对于已解冻的系统,在接通电源和水源之前,请确保没有零件变形。如果在使用过程中出现漏水或其他异常情况,请停止使用,并联系维修人员进行必要的维修。



4. For WaterBaby faucet water filters: please run lukewarm water first and gradually switch to hot water. Using hot water directly will have a chance to cause the casing to break due to the sudden temperature differences.

对于WaterBaby龙头滤水器:请先将龙头开至温水,然后逐渐改用热水。直接使用热水会有机会由于突然的温差而导致外壳破裂。


Notes: let the water run out for a couple of minutes before using the filtered water for the defrozened systems, or systems you have not used for at least a week. For RO systems, you will need to empty at least one tank of purified water before youuse it for drinking/cooking.

提示:对经过解冻的净水器,请打开相关龙头流水几分钟,来确定净水的新鲜与干净。若用的是RO设备,请至少防水1桶或者2桶后再用水来喝跟煮饭等使用.

How to prevent pipes from freezing

如何防止管道冻住


To prevent pipes from freezing, a good solution would be to keep them warm and the water inside running, when the temperature has violently dropped outside. Below are some tips to help you protecting your pipes:

为了防止管道结冰,一个好的解决办法是在温度骤降的情况下保持管道的温度和内部水的流动。以下是一些小贴士,可以帮助你保护你的管道:


· Bundle up the pipes before the cold wave arrives. Use the insulation to tightly seal the places with leaking problems or the pipes not in the wall. Be generous with the insulation since more insulation will ensure less leakage. It is always necessary to use pipe insulator to cover the outdoor tap water pipes. The thick insulator will be like a coat for human body and protect the pipes well.

在寒潮到来之前把管子捆好,并使用绝缘材料将有可能会发生漏水问题或裸露管道的地方紧紧密封。不要过度计较担心绝缘材料的成本,因为更多的材料会确保更少漏水情况的出现。在室外自来水管道中,经常需要使用管道绝缘体来复盖。厚厚的绝缘体就像是人体的外衣,对管道起到很好的保护作用


· Open the cabinet doors in kitchen and bathrooms to allow warmer air circulate around the piping.

打开厨房和浴室的橱柜门,让温暖的空气在管道周围循环。




· Turn off dripping faucets and monitor your water meter to check for unseen leaks once the weather has evolved to a warmer temperature.

关闭滴水的水龙头并监测水表,一旦天气转变为较高的温度,检查是否有漏水。



Note: In case of that pipes burst, please turn the water off at your place’s main shutoff valve, then turn all the inside faucets on to drain the water out of your pipes. The relevant municipal department will take emergency measures to repair the cracked pipes, which will also result in more pollutants like sands, rusts, and other sediments entering the water which will block the water filters. As a result, it is often suggested to have the water filters replaced to ensure clean water and proper function of the water filtration system.

提示:一旦管道发生冻结或爆裂,相关市政部门将采取紧急措施对破裂的管道进行修复。这也会导致更多的污染物,如沙子、锈迹和其他沉积物进入水中,从而堵塞滤水器。因此,在这种情况下,我们会建议您更换对应的滤芯,以确保水质及过滤系统的正常运作。

How to thaw your frozen pipes

如何解冻管道


If you turn on a faucet and only a trickle comes out, this might be caused by the frozen pipes. If the water is still running, you can take the following steps but if you suspect a more serious problem, call a plumber.

如果你打开水龙头后只有少量水流出,这可能是由冻结的水管引起的。如果还是有水流的,那你可以采取以下步骤,而如果你怀疑有更严重的问题,请打电话给水管工修理。

· Run the water all the time if you only have a trickle of water coming out from the taps with frozen pipes. If you know where the frozen part is, you could wrap a towel on it and warm it up with warm water or a hair drier.

如果只有水滴从冻结水管的水龙头流出,则应一直放水。如果你知道冻结的部位在哪里,你可以在上面包上毛巾,用温水或吹风机为它加热。


· Apply heat to the section of frozen pipe using an electric heating pad wrapped around the pipe, an electric hair dryer, a portable space heater, or by wrapping pipes with towels soaked in hot water.

可以使用电热垫包裹在管道周围,用吹风机、便携式加热器加热水管,或用热水中泡过的毛巾来包裹管道,这些都能对冻结的部位进行加热。


· Apply heat until full water pressure is restored. Check all other faucets in your home to find out if you have additional frozen pipes. If one pipe freezes, others may freeze, too.

持续对水管加热,直到水压完全恢复。检查你家里所有其他的水龙头,看看你是否有其他的冷冻水管。如果一根管子结冰,其他管子也可能结冰。


If you are unable to locate the frozen area, if the frozen area is not accessible, or if you cannot thaw the pipe, call a plumber.

如果无法定位冻结区域、无法接近冻结区域或无法解冻水管,请致电管道维修师傅。
