Today I came to Lyle’s Temple rental property because the city is dictating that there be a sewage backflow / backwater valve in the basement for a legal suite. Upon visual inspection I found the is a backflow / backwater valve on the basement bathroom group. Plumbing code dictates a that a back flow / backwater valve must be installed on the basement group or the main line. The system meets current codes. Lyle will let us know if the city wants a main line backflow / backwater valve.
