I moved into a very nice house about four months ago..very upscale house..whom built it did an excellent job..the thing is that last night someone tried to break into the basement door..is there like a security alarm (something like a car alarm) that when someone steps on your property or tried to break open you house..the alarm goes off really loud so that the neighborhood hears..help this is really scary..just think what could happen..
there are two types of resins, a cation exchanger and an anion exchanger. for cation exchangers, from the name itself, it exchanges cations or the metal ions and therefore will be affected if you put different metals such as sodium salt then potassium salt. for anion exchangers, it exchanges anions or non metal ions such as chlorides, fluorides, etc. it will be affected when you put different anions e.g. sodium chloride then sodium fluoride. chloride wont have an effect if you use a cation exchanger resin. but if you use an anion exchanger resin, there will be an effect on the softening properties of that particular resin.
you have to use galvanized pipe and fittings if its being ran inside the structure that your trying to protect. Iron will rust overtime and cease up any valves you might install and PVC will melt in a fire, defeating the whole purpose. I used to work for a fire sprinkler company and we dident ever do much in the way of fire hoses, but we ran all of our trunk lines and mains in galvanized piping. It really depends on what type of application you are using fire hoses for. good luck.
