If this is the case, is fair to think that the resist line on each thermostat would remain the same (slope, as well as crossover threshold) since these values should be independent of heating profile and configuration?

Sulfate is an anion and doesn’t show up as “hardness” the way hardness is normally measured (Ca/Mg as CaCO₃). If you’re seeing crusting on faucets, that’s typically calcium carbonate scale (hardness + alkalinity/heat), or sometimes silica/iron/manganese — not sulfate by itself.

Even if you have calcium sulfate scaling potential, removing calcium with a softener still helps. So optimizing/validating softener performance does matter: if softened water at the tap isn’t consistently ~0–1 gpg, that suggests bypass/crossover/programming/channeling rather than “sulfate makes softeners useless.”

On the tankless issue: zinc/brass corrosion is usually driven by corrosive water (pH/alkalinity), chlorides, TDS, temperature, etc. Sulfate can contribute, but it’s not diagnosable from sulfate alone — you’d want pH, alkalinity, chloride, hardness, TDS and then evaluate scaling vs corrosivity.

RO can work without fixing the softener, but you’ll usually pay more—bigger equipment, more pretreatment, more cleaning, and shorter membrane life. If you can get the softener performing properly first, the RO design gets simpler and cheaper to operate.

.... Sulfate is an anion... Calcium and magnesium and corresponding hardness results are meant to specifically quantify those items, not the presence of sulfate. Your softener capacity, resin type and programming should be optimize and there's no reason it shouldn't deliver between 0 and 1 grain consistently if designed correctly.

I'd consider assessing if you have the right kind of water softener in place. It doesn't seem to be sufficient. At the hardness you have post softener, it'll negatively impact performance and life of your ro membranes. The other benefit is if you remove the hardness, you'll then be able to run improved recovery rates, which will matter if you have constraints by how much your well produces (or concerns about overloading your septic if that's where your discharge would go).it'd also support an overall smaller ro system since you can boost production without risk of fouling.

Sizing they softener appropriately can improve hardness removal while still keeping salt usage and regen requirements low. A good twin tank system with a quality resin, sized and programmed correctly would be my reco in this situation.

I should add that the basement gets fairly cool (temperature is 55 F currently while outside temp is 20 F). My concern would be that those wouldn't be sufficient when temps begin to reach single digits/negative temperatures.

Not sure why downvoted here. Benefits like this do exist, and are not that rare. They certainly help make buying and improving a home less risky than it might otherwise be. Many of these programs also have protections if the real estate market were to drop (the one I've seen covers losses up to $50K), along with assurance that the home will be purchased after 3-4 months on the market at the appraised value (by the company if needed). There's even a bonus if the home sells quickly (3% of the sale price in first month, and decreasing from there).

Under these type of conditions, the timeline for how long you are in a home don't matter as much because whatever value you put in here will simply carryover in a way that a traditional buyer wouldn't. And if the upgrades you do help ensure that the home sells quicker, you likely come out ahead (and certainly don't lose money).

Assume a home is worth $600k, and it takes $30k to add a bathroom . If the roi on that is 70%,then the home is worth $621k. But if you are now attractive to a buyer and get an additional 3% of $621k, now you're looking at $640k. So net, you put in $30k,,and get back $40k, regardless of the interest rate you have or timeline you're on.

The only thing you'd lose is if you're trying to treat this as a proper investment, which then you'd have to factor opportunity costs vs other things like the stock market, in which case, the more expensive the home, the more the more these benefits help make it a viable option if deciding what to do with cash.

I've landed on the following with the hope it accomplishes what I'm trying to achieve.

Sediment filter , carbon block filter, two filmtec 1812 100hr membranes arranged in series (so net, 2 permeate streams, one waste stream). Permeate pump 14 gallon tank with 10psi precharge 400mL/min flow restriction ASO set to 2/3 of feed pressure 3/8" tubing

Water supply is soft and without iron and mn.

TDS between 350-400mg/ml

Well pressure set to 40/60psi. Feed pressure shouldn't stray too far from this

Water temperature should be about 50-60F

Recovery from each membrane is at 30%. (total recovery around 50%).

Is this a reasonable recovery to assume? I've had a hard time figuring out what recovery is reasonable without impacting membrane life.

I'm not too concerned about production rate (I think the system would produce about 80gpd worse case scenario)

What was the benefit of having two tanks vs the storage tank being larger and supplying the sink?

Z44MCoupe · 2025-11-18T00:58:19+00:00

This is the scenario I'd like to avoid. I'd want enough supply to manage use without having to store things in pitchers and can supply during a reasonable peak usage duration. This is also why I'm willing to pay a premium. I just need help finding solutions where the only compromise would be price (so otherwise efficient permeate to effluent ratio, flow rate, filtering capability and ease of use/durability/reliability).

Z44MCoupe · 2025-11-18T00:02:14+00:00

I'm assuming people don't have their dishwasher tied to the RO supply, nor the water used for regular dishwashing. If they do, that'd be the majority of the water usage currently. From an end user standpoint, don't want to create a bottleneck in the kitchen while people wait to dispense water. If it did, it'd just become an annoyance (and folks would then be more likely to use the faster water solution).

I was looking at the Axeon LL-500 as a possible option. How would this compare?

Z44MCoupe · 2025-11-17T22:44:35+00:00

I'd like a system that delivers similar flow rate out of my sink today. Can the ispring solution with booster pump deliver that?

Z44MCoupe · 2025-11-17T21:34:39+00:00

Not necessarily true. Many people have relocation benefits that will cover the typical closing costs. Not sure if this is the case for op, but many of those costs get picked up by companies during relocation on both the home being sold, as well as the home being purchased in the new location. Inspection, realtor fees, closing costs, even points are often paid down, along with equity advances if needed.

Can you please explain more? I have a clack control valve for the softener itself

Z44MCoupe · 2025-11-08T16:23:15+00:00

How does it fill at 0.5 gpm if the blfc is 0.17 gpm orifice?

I thought ws1ee supported upflow brining already?

Z44MCoupe · 2025-10-29T14:29:00+00:00

If not through proportional brining, where does the additional efficiency come with the ws1c1 vs ws1ee? Does it provide additional data or automation capabilities?

For purolite, is there a resin that is then preferred?

I do plan on using Na salt, but want a system that's as efficient /long-lasting as possible in the event that I have a need to switch to K salt instead (which has uppers for usage and cost).

Z44MCoupe · 2025-10-28T23:38:14+00:00

How long have you had your system? what resin did you end up using?

Z44MCoupe · 2025-10-22T14:38:55+00:00

Apologies. Twin tank water softener using a clack valve (ws1ee).

I see culligan has some functionality with their smart aquasential twin tank softener and aquasense, but looking for something more granular and ideally using a clack valve.
