Fleck and Autotrol Valve Seminar

On a recent, very snowy day, twenty-two plumbers, well drillers, and dealer personnel braved dangerous driving conditions to attend the Res-Kem hosted, hands-on seminar on Pentair and Autotrol multi-port valves for residential water treatment systems. These 22 people are owners or employees of 11 Homestead System dealers, www.homesteadsystem.com, from Maryland, Delaware, Pennsylvania, and New Jersey. The seminar was taught by Dave Smith, Dealer Development Manager, and Kathee Srygley, Regional Account Manager of Pentair.



The valves the seminar primarily focused on were two multi-port valves with advanced electronic controls. The Pentair Fleck 7000 XTR valve and the Pentair Autotrol 268 760 valve were studied, broken down and reassembled. Attendees learned how to diagnose and fix common problems. These valves are used respectively in the 3000 and 2000 series Homestead System softeners, neutralizers, carbon filters, city systems, odor removal and iron removal systems. To add realism to the class, Res-Kem enhanced the normal Pentair program by giving a live demonstration of an installed water softener in the Res-Kem wet test area.
Typically, Pentair graciously sponsors similar seminars at a local hotel. We felt having the live demonstration and access to Res-Kem’s complete warehouse of valves and parts would enhance the learning experience. Michael Urbans, Res-Kem Residential Technical Manager instructed this part of the seminar.

In addition to learning about softeners and filters, attendees were introduced to the Pentair Fleck 5600 SXT, Homespring, FreshPoint and RO membrane systems. They were given a sneak peak at the new iron removal valves Pentair will introduce based upon the Pentair Fleck 7000 AIO valve and SXT controller.

WQA members were given .65 Continuing Education Units (CEU) for attending the seminar. If you would like to be on the invitees list for other courses, please contact us.

Setting Brine Tank Refill Time on Fleck Softener Valve

The Pentair^® Fleck^® multi-port softener valve controllers, electronic versions SE, XT, XTR and SXT and non-electronic versions, are very flexible allowing for customization of the regeneration cycle of the water softener. This flexibility requires that you know a little bit about the system and a simple calculation -"Brine Refill Time". Although a simple calculation, "Brine Refill Time" is often misunderstood.

Definitions:
The "Brine Refill Time" is easy to calculate and is the same regardless of valve and controller type.

The following values are based on the design of the softener and valve.

T = Brine Tank Refill Time (minutes)
X = Brine Line Flow Control Rating (gpm)
Y = Salt Dosage sometimes called Regeneration Level (lbs/cuft)
Z = Amount of Resin in Softener (cuft)

In order to set the time you need to know the concentration of saturated brine

C = 2.6 lbs/gallon = Concentration of Saturated Brine

So the equation is:

T = (Y * Z)/(X * C)

Example:

X = 0.5 gpm
Y = 12 lbs/cuft
Z = 2.5 cuft

T = (12 * 2.5)/(0.5 * 2.6) = 23 minutes for brine refill step
