How do you get more "headroom" (freeboard) with a Turbulator dist tube when you have the same volume of resin in the tank, especially when you can't use a gravel underbed? No gravel means more freeboard (distance from the top of the resin to the top of the tank).
How is the 2510 easier to clean iron out of than other control valves?
All the seals and spacers in a Clack come out as one piece in 2 seconds and the 2510 has 5-6 seals and 4-5 spacers that all come out and go in individually. Also, Fleck control valves have a separate brine valve, Clack got rid of the separate brine valve and its gearing and has a small brine piston on the far end of the main piston and its seals and spacers come out/go in with the main piston's seals and spacers stack. I tell my customers how to prevent iron/rust buildup.
