Water softener just quit

Suddenly our Kenmore 44,000 grain softener is barely softening our well water. It has enough salt and I ran a regen cycle thinking that maybe we used too much water and ran out of soft water, with the same results very hard water with minimal softening – it is softening a little.

The well water is of very poor quality 100 grains hardness, 1800 ppm TDS, 1498 ppm sulfides, no iron, ph near 7. We inject hydrogen peroxide into the water stream as it is pumped out of the well into a storage tank where the water sits several days. The water usually has no smell and every now and then a slight odor of sulfide so I assume the injector pump is doing its job. The softener was doing OK for the past six months, not really soft water but quiet acceptable.

Because of the water and several other problems with the property we are trying to legally get out from under the property, so we really don’t want to upgrade the water system any. Alternatively we can go back to using the Rio Grande as our water source as most of our neighbors do. The water is clean but the state health dept, frowns on this practice for health reasons.

I’m assuming that the resin is fouled. What can I use to clean the resin? Most over the counter cleaners I see are for iron removal, we have no iron in the water according to the lab analysis. Do you have any suggestions as to how to get the softener going again? Thank you for your time.

Answer:  You might be throwing “good-money-after-bad” here in an effort to revive your softener.  If your Kenmore is an older unit, it may be practical to replace the resin in the softener with new.  Years ago, Kenmore softeners were good quality units, and if this is an older system you might still expect a reasonable lifetime if the resin is replaced.  In recent years these softener have become more “entry level”, and are not intended to have a very long service lifetime (as evidenced by the 1 or 2 year warranty). Cleaning the resin may not be the way to go – better to replace it with new resin – the resin might have become deactivated over time due to oxidation by the injected hydrogen peroxide, or the resin bed may have become fouled with sediment or sulfur oxide particulate. Replacement ion-exchange resin is available on our site for $130.00 delivered.  The other way to proceed is to replace the water softener.  A good metered commercial grade water softener using the Autotrol 255/762 Logix control, in 48,000 grains capacity, is available for $725.00 delivered. Please let us know if you have any other questions.

What can be done with this water?

We have a drilled well 65 ft deep that gets water from a crack in the bedrock at about 40 feet. Water quality is bad – 1498 PPM sulfates, 1800 PPM TDS and 100 grains of hardness, the well makes about 3 GPM and is very consistent even in this year’s record drought. For many years we have used the well as a backup water source using the Rio Grande as our primary source. Recently things have changed and we need to use the well if possible as our primary water source.

Answer: You have two ways to proceed here:

1) Cation water softener – anion exchange system – pH neutralizer, with an point-of-use RO system installed at the kitchen sink to be used for drinking and cooking water.  The traditional cation exchange water softener will remove hardness (also required for pre-treatment prior to the anion exchanger), the anion exchange softener will remove sulfates, and the pH neutralizer would be installed into last position to increase pH to normal range (the anion exchange system will drop pH significantly).  The cation and anion softener will add a significant amount of sodium to the water, which you would want to remove with the RO system installed at the sink.  This is approximately a $5000 to $6000 dollar solution.  A twin tank 64K water softener with salt efficient Purolite SST-60 resin, 2 ft3 anion exchange system, and 2 ft3 pH neutralizer, approximately $5500.00 delivered.  Less expensive, makes the water usable – but not perfect (drinking/cooking water would be fine at the kitchen sink).

2) Whole house reverse osmosis.  As you mention, the other option you have would be whole-house reverse osmosis. In this case you would still need pre-treatment with a water softener as above, the whole-house RO system, and post treatment with a pH neutralizer.  More in the $8500 to $10,000 range. More expensive and maintenance intensive, but much better quality water.
