Moen Cartridge I have replaced two of them on my own rental
on the same shower, replaced twice, not the shower valve, but the cartridge. within 2 years. One of them happened at night, the shower can't be closed due to valve leak, tenant called me but I was asleep, I missed the call. so tenant called police, finally shut the general valve on water supply in garage. Stupid tenant, isn't it? but anyway, I replaced the Moen shower valve cartridge, but don't know in the first place that no need to replace whole thing bought a brand new one from HD. After the work is done, realized no need to buy the whole set of shower valve, waster money but can't return to HD since the cartridge is used.
Later I bought half a dozen cartridges from Amazon and used only once. So far so good.
Keep finger crossed.
BTW, I also replaced Toilet seal ring, kitchen faucet, toilet seat cover, shower tub drain, and bathroom vent, and caulked tubs, replaced washer/dryer to coin-laundry; replaced stove. Light bulbs - a dozen or more. I also cleaned up roof deposits....patched cracks repaired leaks on roof .... replaced Range Hood by myself.... lots of work done by myself only.

有个房子需要清理fence上的老藤，修剪树枝，还有清理落叶，找了几个landscape contractor报价差不多$800，选了几年前帮我干过活的一家。前几周在他来之前，我就说想等叶子都落下来再清理落叶，他说可以但他怕下雪。在下雪前清理老藤和树枝很重要，所以我就要他来干活。他活干得不错，也把当时的落叶都清理了，最后他说等我觉得可以做落叶的final cleanup了再叫他。当时叶子才掉了一半，等叶子都掉要再等2－3周， 我说好。
我当时觉得他的活干得不错态度也好，已完成了主要部份，而且他主动说了要再来做final cleanup，他发来$800的账单我就全付了。等过了3周，我现在要他去做final cleanup，他就回复说这次要收$300。我和他说我一直以为这是包含在$800里面的，而且他上次也没提他再来做final cleanup要另外收钱。他没有再回复我。
我想我不应该把那$800全付的。我当时确实是相信他，也想着马上是Thanksgiving节日，就全付了。也不知道我是否理解错了他的报价，是不是只包括清理当时的落叶。如果当时我以工作没做完扣下150，要么他会回来清理，要么他会当时告诉我他的工作已做完。
我原准备明年把几个房子剪草的活都给他的，上次一次性付款也有希望双方一开始留个好印象的因素在里面，可惜反而适得其反。
今年明显感到又好又可靠又价格不高的contractor不好找，所以觉得好的contractor就总想保持好关系。
刚收到合作很多的plumber公司账单，换一个Moen shower valve收了600，前几年我肯定会直接问怎么这么贵，今天想了想写了封措辞和缓的邮件去问材料费和人工各多少，得到回复材料295，人工两小时300。我为了分散，已经和三家plumber公司保持合作了，可今年其它两家要么更贵要么不能及时来，这家贵但每次都能及时派人，这在冬天heating季节就比较重要，也只有忍了。
换这个既不需要体力，也不需要脑力，看着新cartridge的说明书就可以换了。盒子里面还附送了需要用的Allen wrench.
去年要另一家plumber去换了一个shower valve，记得收了400多
三个浴室的cartridge全换了，因为用了7年了，有的里面芯子里面很多residue，堵塞了水流而且转动value非常困难。闲着也是闲着，能省1千多刀也不错（按你的plumber的收费标准）。我还教会了LD，他去NY给儿子换了一个。
我的2010年Honda CRV，现在就是我的工程车了，dashboard的灯一会儿亮，一会儿自己好了，俺反正不管，能开就行。破车开着很爽，去见租客更爽。俺准备开到它不动了，也别修了，直接扔了就行。
曾经他教我远程换thermostat，还有换fuse。
换水龙头修水管等都没问题。想着shower valve关不紧有点点漏水修起来应该容易，就要他去修。结果房客打电话来说，handyman动过后valve就关不上了、水一直流，去关了总水阀才把水关住，一旦碰了valve就又水长流。而handyman走了，说第二天再过来。房客不愿等也不愿这个handyman再来，我没办法才去请的plumber，原来想账单可能200－300，早知道是600，就还是要这个handyman去修了。
不然太贵。
他给我免费换了
