Indeed, there are many Ph.D. programs that can be closed. The first one on
my list to close would be the Religion program in Columbia university. Why
do we need Ph.D.'s specializing in religion? Leave that area to the rabis

What is PEX?
PEX is cross-linked polyethylene. Through one of several processes, links
between polyethylene molecules are formed to create bridges (thus the term "
cross-linked). This resulting material is more durable under temperature
extremes, chemical attack, and better resists creep deformation, making PEX
an excellent material for hot water and other applications.

来自主题: Living版 - 请教 hot water boiler 的问题
刚买的房子,heating系统是用 gas hot water boiler。
热水循环系统靠一个Expansion Tank来防止水压过高,靠另一个Pressure Reducing
Valve (Automatic water feeder)来防止水压过低。如图。
请人来检查的时候发现 Expansion Tank里已经全部是水,所以当水热起来压力高时就
会从排水管排出。然后那个water feeder好像也不起作用了,拉动手动扳手的时候听不
到水流声。
现在暖气还能用。请问这两个零件是不是一定要马上换?
然后我们接下来装修的时候可能要改楼上的热水管,这样就需要把循环系统里所有的水
都放掉。我的理解是现在虽然water feeder不给水了,循环系统里的水还能撑一阵子。
但是如果装修的时候把现有的水都放掉,就一定要修water feeder了,不然暖气就不工
作了。
请问这个理解对吗?
多谢!

Not necessarily. Some more expansive air filters are claimed to filter out
bacteria, smoke, etc., which the cheaper ones do not.
If you're talking about health for your families, a little bit more $ is
really worth it in this case. You can even change the more expansive filters
more frequently if you want, but the suggestion is to stay away from the
cheap ones.

铺木地板时地板与墙应有 expansion gap,你在这里有两个选择:
1. 地板离墙0.5寸;
2. 将 drywall 割掉一些,地板与墙对齐。
我选的是#2,因为如果用#1,将来装 baseboard 的时候要用 quarter round 来将
expansion gap 盖住。
房间的一边墙原来已经离地,另外两边就没那么好运了。先用锯锯掉门框,再用
oscillating tool 将 drywall 割掉一些,离地稍比木地板高些。

),被问若干信息,报价九百余(热水器400多),同时提到有新的code,要求安装一
个expansion tank,二百余,总价一千一百余。同意
给township电话询问,得知expansion tank确实需要(其实我也没弄清楚那个干什么的)
Sandy当天,某胖男出现,逡巡一圈说,除了这个还要换开关若干,管道若干,共计一
千八百余。大怒,拒装。
半小时以后接到电话,好象是某首脑人物,还价至250刀装管道/开关,总价14xx.从之。
半小时后胖男再次出现,表情严肃,2.5小时之后完成。不得不说,活儿干得非常利索。

向大家请教是不是该加水:
UTICA BOILER MODEL# MGB175HD, 去年夏天搬进来时feed valve TACO 329前面的shut-
off valve是关着的,一直没有动过。冬天一月份拍了温度和压力的图,最近感觉
baseboard heating line有水进了气的哗哗响。发现boiler不烧的时候基本没有压强,
烧起来
压强高点但是也比一月份低,不烧了又低下去了。另发现air separator出口沾着少量
水。baseboard和墙周围没有发现漏水迹象。
问题:1. 我是不是应该打开shutoff valve补水? 2. boiler的压力是不是由
expansion tank调整的?温度高里面空气热起来压力就高? 3. 因为expansion tank 体
积不大,不需要失去多少水就会导致水压下降很多?
贴图由上到下: 第1是一月份照片,不清楚当时是不是在烧;第2.今天Boiler没烧时照
片;第3.烧热起来;第4. 不烧了在冷却过程中。
