Have few questions about the above mentioned.
In residential construction, which one is preffered ? From what I red,
arrestors cost more and are more likely to fail after certain time
(mechanical device), chambers have to be "recharged" overy once in a while
(how often?) Seems to me that chambers would be better, and cheaper - am I
Also, at what points do the need to be installed? Is there a rule, ie.
every fixture, or just end of the run - both hot and cold? Also, is the
chamber supposed to be same size as the pipe or can it be smaller (ie should
i use 3/4" chamber on 3/4" piping, or 1/2" is good enough?
thanks to all.
