For fire sprinkler riser assemblies that include a control valve, waterflow switch, check valve, inspector's test and drain, or a dry/pre-action system valve, are there any height requirements or limits with any of these components?

System valves and gauges are required to be accessible for operation, inspection, tests, and maintenance.
