Hello, I have been looking over this site for a while now and have done a bit of research prior to trying to ask my own questions. I am at the point however where I need help picking out a valve.

I
have done the research, read reviews, had several water tests done, and
have determined that I want to buy online due to cost savings and my
relative handiness. I want a gravel underbed, quality domestic resin, a
top basket, safety valve in the salt tank, a 33" salt tank, a noryl
bypass, and a Fleck valve.

I have about 14 grains of hardness, 0.5ppm iron, and a slight sulfur
smell in both the hot and cold (more prevalent in the hot, but it is
present in the cold). The house is 2.5 baths, and we are planning on a
family of 4. This has me looking at a 64,000 grain unit.

All that said, I have no idea what valve to choose and each bit of new
info makes that decision harder rather than easier. If I could get a
Clack valve online and install myself life would be a lot easier, but I
know that is not possible. I have read the spec sheets and other
documents for each valve on the Pentair site, and have watched a number
of videos posted by water treatment companies.

At first I was looking at the 5600sxt, but after reading that the 64,000
grain unit was at the valve's upper limits, the special tools needed
for DIY repairs, and its basic programming options I started looking
elsewhere.

The 7000sxt was suggested due to flow rates, though a website I was refereed to mentioned this:
"If you have a home with 4 bathrooms or less and still want a high flow
system, please consider our Fleck 5000 SXT Pro Flo system.The Fleck 7000
SXT systems are designed for larger homes with 5 bathrooms or more."

The 2510 was described to me as similar to the Clack ws100 valve both in
operation and ease to rebuild. However I am worried that the the
programming is too complex for the first time DIYer.

Lastly is the 5000sxt suggested by one of the websites, though it is new
to me and I have admittedly not read up much on it. I plan to change
that this morning before I head to work.

I know the decision is ultimately mine, but I was hoping for some
opinions by people more knowledgeable than myself that might make my
decision a bit easier.

Thank you!
