CR100 with KDF-85

[royerm]

Good morning everyone....

I have a situation with a Greenway(Sanitizer) water softener that contains CR100 and KDF-85.
I installed the unit last May(10 months ago) and ran Ok for 2 months after which a
rotten/sulfur smell showed-up for which I was prescribed to add some KDF-85.

It ran ok till this morning(8 months) when the smell is coming back.......

I have a CSV installed with a small pressure tank, the setting (30 grains) on softener shows that I should
go for 733 Gals before regeneration but I run it once a week when I have used approximately 400 Gals.

Here's the situation...I open a tap and no smell, after a minute or two the smell shows-up and if I let it
run for another 2 minutes the smell goes away again.
I have ran that scenario a few time and same result????

I'm trying to foresee a possible problem before it gets worst...Thx

What is the iron level? ppm?
what is the hardness?
Backwash time?
Brine draw/slow rinse time?
Rapid rinse?
Brine refill time?

Brine refill time?

Iron 3 PPM
Hardness 9
Backwash 12
Brine draw/ rince time 90
Rapid Rinse 4
Brine refill 9:53

I took these number from the specs book, I'm not sure
if I can see these on the display, not seeing it in the documentation.
It seems like a preset depending onf the model #...???
Thx

What size tank is the unit?
10x44 or 10x54?
backwash time for the 10x54 is 16 minutes
Brine draw is correct
Rapid rinse should be 1
Brine refill is most likely correct for the amount of salt to be used next.
Is this the Clack valve that Water Right is using?
You are going to need to program it for your water, other wise the unit is going to continue the failure that it is doing.

[royerm]

Tank is 10x54 and it is a Clack valve(Water Right).

Nothing like reading a bit more, found out the parameter from the starting procedure.

Fill 9:53
softening 240
back wash 12
Brine Draw 90
Rinse 4

So I gather that the back wash is not long enough????

One of the things is yes the backwash needs to go to 16 minutes.
Rapid rinse needs to be cut to 1 minute.

What do you mean by softening 240?
