FYI The distance from a fitting or valve is only a "should" not a shall. There are no UL or NFPA requirements regarding distance. There are a number of riser assemblies on the market that put the switch closer than the stated 24" from a valve or drain. If the switch works during the test after installation it's a good installation.
