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.

Our recommendation would be to most definitely install a reduced pressure principal backflow prevention assembly at your well to prevent any unforeseen possible contamination of your drinking water, remember that in your apparent circumstance you are 100% responsible for any contamination that may occur.

If your swimming pool or hot tub is filled with a submerged inlet water fill, both would require a reduced pressure principal backflow assembly. State of Illinois Plumbing Code Section 890.1130)(a) Protection of Potable Water requires:
"Cross-Connection (Submergence). Potable water supply piping and water discharge outlets shall not be submerged in any sewage or toxic substance. Potable water supply piping or water discharge outlets that are submerged in other substances shall be provided with backflow protection as listed in subsection (f)."

The complete Plumbing Code is available on the Illinois Department of Public Health website, www.idph.gov.
