The headers for Nelsen multi-tank softener systems are designed for tanks rated at 2-5 gpm per CF resin.
Multi-tank softeners with 10CF of resin or more with 2" regeneration control valves will have 3" interconnecting pipe headers for system flow rates up to 240gpm total. Multi-tank softeners with 3" control valves have 4" headers for system flow rates up to 360gpm.
Multi-tank systems with flow rates greater than 360gpm require 6" or larger headers and are not supplied by Nelsen Corp. 6" and larger headers are the installing contractors responsibility and are not included in Nelsen quotes.
Header and Interconnecting Piping is only available when purchased with mounting skids.
