Bright Leap: Install Central Vacuum

中央吸尘是现代健康生活必须具备的。如今所有的新建房屋都有中央吸尘中央吸尘的管道和电线已经铺设在墙里面，没有完全连通，还用不了。要做最后的连接才能使用。“最后的连接”可以是很简单，也可能很复杂，看实际情况。

Step 1: Make sure the home has the 'rough-in".

很容易找到车库里的管道出口。

我在一楼找到两个，在二楼找到三个。这五个中，只有一个与车库的那端相连，而其余四个只是接到地下室而已。

我花了相当长的一段时间才找到地下室的两个开口端。一个在炉的正上方，另一种是空气流动管道的上方。必须站在梯子上，才能看到。

第2步：买个中央吸尘器。

我先买了一台，税后750元。后来见到一个评论，说，经过500小时使用后，这个中央吸尘器将自行关闭。那时必须搬到维修服务中心，维修后，才能再用。我联系到厂家，确认有500小时停机维修之说。然后我又联系到了一个服务中心。现时的服务费为140元。做个简单的数学，假定我们每周累计吸尘2小时，大约5年后，我们要再花费140元，（没准还要涨价到更高），税后158元。假定它的使用年限是15年。5年后的价值是500元。维修费的比率是158/500，31.6%。是否值得？算啦。收到后，我立马退掉。
Then I bought a hoover (again). I was using Hoover in my previous home too.

Step 3: Make a rough plan and buy all the parts. Buy some extras.

Please note, there are two colors of the PVC glue: clear and grey. Also there are two types of 90 degree elbow connectors, bought a few for each. I bought the phone wire (cat 3).

Step 4: Drive a hole from basement to the garage, and seal the hole gaps afterwards.

Step 5: Connect pipes.

There is a special PVC pipe cutter. We won't use it a lots of time, So I just use this handy steel saw instead. Use papers to clean the cuts.

Before gluing, must do a dry fit test, and make marks for correct angles. The glue drys quickly in less than 5 seconds.

Step 6: Connect wires

Connect the inlet on the ground floor and the second floor. Theoretical, use two of the four wires is enough. So at the beginning, I connected only red and green. Late, to get a double insurance, I employed all of the four wires.
