About a month ago, a new water softener was installed in our home. We were told that we would need a new bag of salt about once every three to six months. As it turns out, we've gone through about one bag per week. Also, the water feels really oily. Yes, soft water does that - but this water feels much oilier than the water at our friends' homes or local businesses, many of which use water softeners. It actually feels dirty, and the dirty feeling remains on our hands until we rinse in nonsoftened water.
Is there a quick adjustment I can do? Or is this a job for the experts?
Not sure if this is your problem but that is a common complaint of water softeners. But I'd have the installer come back out and check the o-rings and adjustments. I wouldn't DIY.
Sounds like your water is waaaaaaay softer than you want it -- and softer than it needs to be. Every water softener I've ever seen has some mechanism for adjusting the amount of salt used per cycle (and hence the softness of the water).
Undoubtedly there is an adjustment. The owner's manual will tell you how to do this. If you didn't get an owner's manual, complain to the installer, or search online.
It could be backwashing too often using up salt so fast. But even if you set it to backwash less frequently the water will still be just as "oily", as the salt has nothing to do with the actual softening process. The salt is used to break the ionic bond the filter has on the extracted minerals, making the filter "clean" again for the next cycle. If anything it could be that your filter is a little oversized for your hardness and it is filtering it more than you would like it to and making it more "oily".
You will probably have to just get used to the level of softness, but you may be able to use less salt by slowing down the backwash interval.
It is a common misconception that the salt actually "softens" the water, it doesnt. Salt is merely used as a brine to clean the filter. The number of "plastic beads" in the filter is the only determiner of how soft the water comes out. The installer should have sized the filter tank based on the chemistry of the water as measured with hardness test, He probably oversized to filter too much so the water is coming out "extra" soft.
Incorrect. The softer the water, the more slippery it feels. If you want it less slippery, make it less soft.
The frequency with which the softener refreshes is supposed to depend on the amount of water used. The degree of softness is adjusted by changing the amount of salt used each time it refreshes -- not the frequency of refreshing.
Also incorrect. Water softeners work by replacing calcium and magnesium ions in the hard water with sodium ions; the source of the sodium is -- you guessed it -- the salt you put in the brine tank. The purpose of the backwash is to refresh the resin bed with sodium.
Most likely, it's just set to make the water too soft, and can easily be adjusted to make it the way he wants it.
What he really needs to do is reduce the salt consumption setting. His owners manual will describe how to do this.

"Hardness" is the amount of calcium (mostly, magnesium also contributes) in the water. The gadget is a cation exchanger, which takes away the calcium in exchange for sodium. The salt solution (brine) is used to regenerate the cation exchanger once it has yielded all the sodium in exchange for the calcium taken out of the water.
I have a derelict softener in my basement that came with the house when we bought it. Same problem as OP - the water was feeling slimy. We cut out the softener from the water circuit, and almost all is fine. Our Jersey water is potable, but to me it stinks and tastes foul. Brita filters are used for drinking water.
I need more "soap" to wash myself here than in places with softer water than our Jersey water. Because the calcium in the water "occupies" some of the "soap" and renders it unusable. This is more noticeable with real soap (sodium palmitate or stearate) than with synthetic detergents.
One bag of salt every 3-6 months is silly...if that is all that was actually used your water wouldn't need softening to begin with. Salesman hype...
One bag a week is silly too...if you actually needed that much I doubt the water would flow (be in a liquid form) let alone be potable.
Water is either hard or soft. In residential that means 0 gpg is soft or 1 or more gpg is hard. The goal is consistent 0 gpg soft water after the softener. A softener allowing more than 1 gpg through it is not working right.
Sodium form resin, negative charged sites on the resin beads, is used to remove calcium and magnesium which makes up hardness, ferrous iron, manganese, lead, radium, copper etc. etc.. They are positive charged ions.
For each of them, two sodium ions are released into the water stream. All chlorides in sodium chloride (salt) is flushed to drain. All excess sodium is also. You get 30K of regenerated capacity per ft3 of regular mesh resin and that requires 15 lbs of salt per ft3.
You never run a softener out of capacity before regenerating it so there is always some capacity remaining when it regenerates, like your gas tank when you refuel the car. The optimal schedule is once every
7-9 days.
Every softener in the world has an adjustable K of capacity. It depends on how much and what type of resin, and THEN the lbs of salt used per regeneration. Regular and fine mesh and SST-60 are the three types of resin. Usually no one actually needs anything but regular mesh unless they have high iron (say 4-5 ppm or more )and then SST-60 is the better choice. Fine mesh resin has a much higher pressure loss than the other two. At 15 lbs per ft3 you get 30K of capacity, at 9 lbs/cuft you get 24K, at 6 lbs you get 20K and so forth. Divide the K by the lbs and you get the salt efficiency; just like figuring fuel mileage, gallons into miles =3D mpg, grains into capacity =3D grains/lb of salt.
I sell many softeners across the US and many use as little as 3-10 lbs on average every 8 days. So a 40-50 lb bag every month or two is not unusual; it's my norm. In other cases, 15lb every 4 days for a family of 4 with 40 gpg hardness and 4 ppm of iron in OH the other day. My record hardness is 136 gpg in PA.
The amount of sodium added is, 7.85 mg/l per grain/gallon. I.E. 20 gpg
7.85=3D157 mg per roughly a quart of softened water. Slightly more than the sodium found in a slice of white bread or an 8 oz glass of 2% milk.
All softeners can us potassium chloride but, if you are using a salt setting of 6 lb/regeneration or lower, you need to increase the salt dose lbs from 12% to 27 percent higher. And potassium chloride costs
3-4 times more for the same size bag.
There is another part of correctly sizing a softener and it is the constant SFR (service flow rate) gpm. It is dictated by the volume of resin in the tank. Every time the SFR gpm is exceeded, the softener can not remove all the hardness because the water is going through the resin too fast for the ion exchange to occur.
