Water Softeners and Air Filtration Systems - Fleck 7000SE or 9000SE Twin Tank with KDF55 Media Guard

Hello,

I’ve done some research online and have narrowed my choice down to the Fleck7000SE with KDF55 or Fleck9000SE with KDF55 system. I am just not sure whether we will need the twin tank or not??
There are 3 people in the household, with 4 bathrooms and 7 GPM hardness and Chlorine at 1.2 (City Water).
Also I would like to get the GE Merlin RO system. Does anyone here know if it works well?
Will the KDF 55 Media Guard remove the chlorine well or are there any other recommendations for the Chlorine removal?

Thanks
Susi

If you choose a Merlin RO make sure you have adequate water pressure and volume available.

In order for the Merlin to do it's magic it requires higher constant water pressure and volume than a conventional RO with a storage tank.

The advantages to a twin resin tank softener is 24/7 soft water. Also the resin regenerates with soft water instead of hard water which will result in longer resin life, but with only 7gpg hardness that's not such an important consideration.

I suggest you look at a softener with a Fleck 2510SE control valve. A reliable design with an impressive service history in the field. Service docs and parts are readily available.

Hello Justalurker, thanks for your answer!

I got my water softener with the Fleck 2510SE, SST-60 restin and the Merlin yesterday.
My husband and I will install it tomorrow (I get all the information to install it and he basically does what I tell him :) )
Anyways, I have a few questions about the settings for the Valve. The SST-60 resin is supposed to use 1/2 the salt and water, but how do I have to set the Fleck 2510SE for that? I guess the factory settings will not work for this resin or do they? Also I calculated that the system needs to recharge after 4290 gallons used (3 people x 65 gallons (we don't use 75 gallons per person a day) = 195 gallons per day. 195 x 7gpg= 1365; 32000/1365 = 23; installations said to back up one day 23 - 1 = 22 days x 195 (water used per day) = 4290) As far as I understood this, the factory settings are A-14, recharge every 14 days or 833 (which has to be changed to our usage (4290)) gallons, whichever comes first. Should I change this A-14 to A-22 per our water usage calculation?
Hopefully someone can help :D

SusiQ,

Regenerating every 22 days is not a good idea. Best to regenerate every 6 or 7 days with a single resin tank softener. Who sized this softener... you or the seller?

Before ordering you should have provided your softener supplier with the results of a comprehensive water test. Their softener sizing and programming recommendations should have been based on those water conditions, water usage, and few other things.

You should be discussing the programming settings with the seller and asking their advice since you will be yelling at them when/if you are not satisfied.

You paid them so get your money's worth and let them do their job.

Posting questions regarding a new softener's settings on DIY forums will result in as many different answers as the number of replies and the number of forums you post on. Some responses will go so far as to demean you for not buying your softener from a particular seller.

Well never mind.
I am just trying to understand how everything works, so I do not have to rely on anyone. That's what DIYing is all about, isn't it? (well, at least most of the time)
The below calculation was given by the seller with the installation instructions.
So if I can't find the information I need in a DIY forum, I guess I will have to find it elsewhere.
Thanks anyways!

Take the amount of people in the home x 75 (or 60) gallons per person per day x the hardness of your water then divide that figure into the capacity of your softener's resin based on the salt dose being used and subtract 1 day (for reserve) to get days between regeneration. Typically you want to regenerate no more frequently than every six days and no less frequently than every 14 days.

Once you know the variables you program the control valve. You have to set the resin's softening capacity at a specific salt dose, the specific salt dose you are using to get that softening capacity, and the water hardness. In the 2510SE there's a "calendar override setting". You set that to the maximum number of days you want between regenerations. With that set, regardless of water usage the softener will regenerate at 2AM the next morning of the calendar override day.

You are doing the math correctly, BUT 22 days between regenerations is too long.

Even setting the calendar override at 14 days, the longest I'd do it, you are wasting a considerable amount of a 32k softener's capacity. Based on the limited details you have provided I wonder why the SST60 resin? You aren't close to using a 1 cu ft softener's softening capacity with standard resin, let alone SST60 resin, and a 7 day regeneration cycle.

The SE master programming instructions (all the hidden settings) can be found if you click here (http://www.ohiopurewaterco.com/40608%20(RevA)%20Insert.pdf)

With 3 people, 7gpg hardness, and no iron or manganese the numbers indicate a .5cu ft or .75 cu ft softener is a better size but the SFR would be lower than the 9gpm SFR of the 1.0 cu ft softener you have. If you ordered a 32k softener based on the SFR then this is beginning to make sense, but again, your details are sketchy and you leave many questions unanswered.

It's always nice when people appreciate that others will give their time to help them and share their knowledge and experience... and then don't appreciate it.

I hope you get this sorted out and working properly.
