嗯，我要analytical grade的才放心lol
看了眼，那个视频，拿个光滑的玻璃管做模拟，放一些新鲜的食材(aka垃圾模拟物品）基本就是博眼球…
你真的拿个内窥镜去看堵着的管道内部，那是完全不一样的，时间+细菌 日积月累发酵后的各种东西黏附在管壁上。
blaster对于新一点，拐角不多，主管道又粗的情况多半是有用的，但长期下来管壁变厚肯定没法改变。就像我说的，治标不治本。

单开关的？听上去像是龙头本身的问题。
干净的进水管还真没怎么听说过堵。不过也可能某个位置的阀门导致水压波动？

Yelp上quote了老美的800~1700，最后找了个华人，snake+hydro jetting 300块 
是的。
温度非常不稳定，有时候突然就只有热水很烫，有时候只出冷水。出水量也不大
我错误方式endoscope 硬捅…
淋浴下水只剩下小手指大小一个洞
不知从哪里看来的： 如果有选择，物理方法 》 化学方法。
所以本坛坛主传说是物理粉。
有大树的话有什么风险?
这里树根也爱垃圾中餐，会刺破污水管去找地沟油脂块。
友情提醒：氢氧化钠固体是Class 8 packing group 2的危险品。虽然少量运输可以走limited quantity，以规避冗杂的危险品邮寄流程，并不代表无危险性。配置溶液请务必佩戴手套和护目镜。
若有多余的碱液，可以储存于聚乙烯塑料瓶中，拧紧瓶盖做好标签。另外固体氢氧化钠要注意密封，避免潮解。

NaOH可以融化头发？怎么配比溶液，难道还需要秤？ 
这玩意疏通头发油污无敌好用。我直接倒1lb干粉进去，再烧一锅开水，倒上去咕噜咕噜冒泡，然后就通了。
在亚马逊买了几次10lb的桶后，我直接买的40lb的一大桶。放开了用。
这东西单买挺贵，1lb就要差不多10块钱。我买的40lb总共$120。合$3/lb
干粉直接倒局部发热小心啊…不巧的话把塑料管子都融了。还是配溶液安全点。而且粉状不好handle，还是pellet安全可控。
树根进去那就基本n张白金开卡消费要求搞定lol
以我20+次的经验，融不掉。这玩意我已经用掉了差不多40lb了。
直接用瓶子倒就完了，都不用拿出来，非常好handle。
不好说了, AI 的答案， 按我估计大概率是1
If a faucet randomly switches between hot and cold water, it could be due to issues with the thermostatic mixing valve, faucet cartridge, or even the water pipes themselves.
Here’s a breakdown of potential causes and solutions:
- Thermostatic Mixing Valve Issues:
- What it is: These valves are designed to maintain a consistent water temperature by mixing hot and cold water.
- Problem: If the valve is faulty or damaged, it can cause the water temperature to fluctuate.
- Solution: You might need to replace the thermostatic mixing valve or cartridge.
- Faucet Cartridge Problems:
- What it is: The faucet cartridge controls the flow of hot and cold water.
- Problem: A worn or damaged cartridge can cause the water temperature to fluctuate or even reverse.
- Solution: Replace the faucet cartridge.
- Pipe Issues:
-
Problem:
- Proximity of pipes: Hot and cold water pipes running parallel can transfer heat, causing the cold water to feel warmer.
- Cross-connection: A cross-connection between the hot and cold water pipes can cause hot water to come out of the cold tap.
-
Solution:
- Isolate pipes: If the pipes are too close, consider insulating them or rerouting them.
- Address cross-connection: If there’s a cross-connection, you’ll need to repair or replace the plumbing.
- Other Potential Issues:
- Water pressure:
Low or high water pressure can also contribute to inconsistent water temperatures.
- Clogged drains or faucets:
Clogged drains or faucets can restrict water flow and cause temperature fluctuations.
- Water heater issues:
A faulty thermostat or water heater itself can also cause temperature problems.
Troubleshooting Steps:
-
- Check for other water demands:
See if the temperature fluctuations occur when other faucets or appliances are in use.
-
- Inspect the faucet cartridge:
If you suspect a cartridge issue, you can try replacing it.
-
- Check for leaks:
Look for leaks around the faucet or pipes, as they can indicate a plumbing problem.
-
- Contact a plumber:
If you’re unable to identify or fix the problem, it’s best to call a qualified plumber.
