Are backflow preventers required on a well serving hotel property? Or are check valves suffiecient? Are additional check valves required to the supply piping of swimming pools or hot tubs? Thanks.

A few days ago I received in the mail a very cryptic survey form asking about something called back flow and back flow preventers. My home has a hot water heating system (radiators) installed in 1914 and a Weil Maclane boiler installed maybe 10 years ago. How am I supposed to tell if this boiler has a thing called a "dual check backflow preventer" on it somehwere, and what is a "make-up water supply" anyway? Also, you seem to be saying that every water spigot I sometimes connect a hose to, requires a thing called a "hose bib" with something called a "vacuum breaker" on it. Is that true in Oak Park? If so, why haven't we been told about it before now? Is this something I can buy over at Menards?

Would you please tell me if I need to have the "Backflow” device (RPZ), that is installed on my Lawn sprinkler system, inspected annually—if the system is connected to my private well and I do not have public or city water coming to my property, in the state of Illinois?

I have not been able to find that information when it concerns a private well.

If you cannot answer my question would you please tell me who could?

 

Thank you..............Bob Z

]]> Tue, 22 Jul 2014 03:09:03 GMT RPZ device for my lawn sprinkler system https://www.isawwa.org/forums/posts.aspx?topic=948790 https://www.isawwa.org/forums/posts.aspx?topic=948790 I need to install RPZ device for my lawn sprinkler system. Can this device be installed vertically or it must be installed horizontally. I am working with the tight space where the pipe is going up and then horizontally right by the celling so it is almost impossible to install the valve horizontally. I live in Cook County, Illinois.

He is not a licensed plumber so he would not be installing or removing any devices just testing them. If he is not able to perform work in Illinois, can you guide me on what he would need to do in order to do work in Illinois?
