If you have an Eruv Chatzeros for carrying, how often is it necessary to check it to make sure that it is properly strung and you can still carry on Shabbos?

A swift surf of the net revealed that the following check their eruvim weekly: Toronto, Phoenix, YU, NW London, LA. There is an interesting document at israel613.com/books/ERUV-E.pdf which quotes the practices of Gedolim in also checking weekly. –  Avrohom Yitzchok Aug 15 '11 at 16:46

I think you need to check any individual string, lechi etc. more often then it would break on average because then you have a chazaka.

Are we assuming a Poisson distribution? –  msh210 Aug 22 '11 at 21:08

Ideally, you should check the eruv before every shabbat/day you make use of it.

However, there are those who say that if there is no major weather change you can rely on a chazakah. But I believe this is only for eruvin that are hard to check. You really should check every Thursday night or Friday before Shabbat.

If it rains or there is a strong wind or snow during shabbat most say you can still use it.

I welcome sources from the community. (My source is from being on an eruv checking committee for a few months)

I know my local eruv's checkers check it weekly before Shabas, but not before yom tov (unless it's a yom tov that coincides with Shabas or is immediately before/after Shabas). (Eruvin are important on yom tov also: without an eruv, one can't carry anything outside on yom tov unless it's needed on that day; with an eruv, one may carry anything outside as long as he's not doing hachana. (Of course, CYLOR.)) –  msh210 Aug 15 '11 at 18:38
    
On shabbat, anything that isn't needed for the day is muktzeh.... so how can you carry it anywhere? An eruv does not change what you are allowed to carry... only if you are doing malacha or not. –  avi Aug 16 '11 at 10:40
    
Right re Shabas, but I was discussing y"t. –  msh210 Aug 16 '11 at 16:57
    
Do you have a source for that? I've never heard of such a thing as an eruv chetzrot for yom tov. –  avi Aug 16 '11 at 19:37
    
Erm, a source for not being allowed to carry outside on y"t when it's not for the same day's benefit? Not at hand, but any halacha book that discusses m'lacha on y"t should have it. –  msh210 Aug 16 '11 at 20:44
