That is one way. I guess you're stuck with that if you can't think of any others.
Where do you have any figures to support that. Fleck still sells a crap load of non metered heads We still sell a crap load of non metered heads.
I guess you don't know it but there are four (4) monthly magazines that many water treatment dealers subscribe to. I started receiving them in 1987 and read every word in those I received every month for many years. Info like how many and what kind of control valves plus a lot of other of the same type of info is published in them. It is a very inexpensive means to stay informed about the industry. Sorry to hear you don't, but many plumbers, well drillers and pump guys don't, so you aren't alone, just wrong and uniformed I guess and your customers pay for it.
Also, why are you putting your customers into a type of softener that causes them to use up to 50% more salt and water than the same control valve in a metered version would save them? I guess I've already answered that, sorry.
Yep, and like I said, most are going to forget to do just that
Now that I believe cause you don't have any customers anymore
My customer don't have to remember.
About 3-4 weeks ago a guy I sold and installed a softener to in July of 1994 called me about it not producing soft water the last few weeks and it had too much water in the salt tank. We found a loose brine line compression nut. It was a metered 5600. Now I call him and others I've sold to over the last 24 yrs my customers, but you can just keep acting like a little kid and call'em anything you like and be wrong again.
