The illustration above, adapted & expanded upon from a Morton® System Saver® water conditioner installation and operation manual, shows the proper sequence of plumbing connections for typical residential water treatment equipment. Water supply brought from a municipal supply or from a private well, pump and tank system feeds through an optional sediment or iron filter and in to the water softener.
A cold water line for outdoor water hose bibbs or other outdoor uses is taken off of the system ahead of all water treatment filters and equipment, but all water entering the building flows first through the water treatment system such as a water softener or if neede a water disinfection system. This sequence reduces the chance of contamination or clogging in the building's water supply piping, water heater, or other equipment.
Below are typical water conditioner or water softener plumbing recommendations. Be sure to read and follow the installation instructions provided by your water conditioner manufacturer as those may differ.
I am required to put a barrel filled with stone for my softener drain, I will only be 2' from my basement wall (concrete poured wall). Will I have problems with this? What should be a safe distance. The soil is sand. I have absolutely no other place to put it. Thanks for any information. - Joe 11/23/11
First, a solid barrel filled with stone won't work as a water softener drain destination; once the barrel has filled it'll just overflow. If you mean that you are trying to construct a drywell or seepage pit to accept water softener drainage, that might make sense. But you need to keep the drywell far enough from the foundation wall so that water from it doesn't leak back into the building, nor into the septic system.
While a concrete foundation wall is somewhat leak resistant, cracks, seams at the footing, and even direct moisture penetration mean that putting a drywell right next to your house is asking for an eventual water entry problem. With sandy soil it's an engraved invitation for water entry. If your foundation is a really tight one the water may not appear immediately, but eventually I expect it'll find its way inside. I'm sorry but I am doubtful that this will be a usable long term or even intermediate term solution. You'd be better off finding a more distant location (with sandy soils, 20 feet or more away) even if you have to use a pump to move the wastewater.
Typically the water softener or water treatment drain is taken to a building laundry sink or to a floor drain, keeping the outlet of the drain line 1-2" abover the floor drain to assure an air gap and to prevent back-contamination of the water system.
We recently installed a water softener in our home. Before we installed it, our water pressure was fine. Now that we have filled it with salt and recharged it, we have very little water pressure. Why is this? If I hit bypass, the water pressure goes back to normal. - Angela 10/16/12
If the water pressure problem has been present since the softener was installed, I suspect an installation error, such as a copper pipe joint partly blocked by solder.
If the problem is not since new but has just occurred, perhaps the bypass valve is not opening fully when in softener mode.
You DID put the salt in the right tank, yes?
Ps in links at page top see our article on the Bypass Valve for repair instructions.
Commode and kitchen sink gurgles/bubbles and water drains from commode bowl while neutralizer/softener operates.
What is the problem, please? - Linda Kennedy 12/7/12
If a kitchen sink drain and toilet are bubbling that suggests that the plumbing vent system that should be serving those appliances is absent, blocked, clogged, missing, or improperly installed;
You may be noticing the noises when the water softener is in backwash/regeneration mode more than at other times because of the added water volume passing down the drain line or because of the point at which water softener drainage is being connected to your plumbing drain system.

I have a GE model GXSF27E water softener. There is water leaking in the rim pan and flowing down the back of the unit. What is the cause and how do I correct the problem?
Tom I'm not sure what part you refer to by "rim pan" - that's not a term that GE uses in the Water Softener manual for the Model GXSF27E. You can use our email found at our CONTACT link to send me a photo of where you see the leakage and I can comment further.
Or you can check the References section of this article ("Click to Show or Hide Citation& References" at the bottom of this article) where I include a link to a copy of the Owners Installation and Maintenance Manual for the GE Model GXSF27E Water Softener. There you'll see a parts explosion that may tip you off to which gasket or O-ring needs replacement to stop the leak you cite.

I have a Kenmore 350 that quit cycling. I can manually recycle and it works fine and I get soft water. I have gone to the diagnostic screen and it shows water flow. Any suggestions?
As you are able to make the system work manually it sounds as if the control head or timer need repair or replacement.

The city recently came in and changed our water reader and once they did our water consumption went from 10,500 gallons to 55,500 gallons of water in a 28 day cycle. The only thing running when we were notified was the water softener BUT I do not know for sure if it was in its cycle for the day or if it was the problem. The thing is the city just replaced their head in our basement a day before we started wasting water. WHat gives, if anything? Is this normal or was it just our luck? Any ideas would be great. Thanks

I'm new to having a water softener.. I don't know how to use this thing, don't know how to adjust it, and can't get it to cycle. How often should it cycle for 2 people living in the house? There are NO stickers or labels on it anywhere to tell me what make/model/mnfctr it is either. I'm pretty sure the dern thing hasn't run in over a week now, the water is starting to smell really strong... HALP!

Similar to the question "discolored water after water softener regen cycle". I cleaned the brine tank but I still get discolored water afar regeneration. We have only noticed the discoloration in the 2nd bath toilet and tub, nowhere else. it clears up after 3 flushes.
Kawika, I'm just guessing, but it seems to me that if water looks different colors at different fixtures in the building I'd think the root source is not the softner (that all water passes through) but perhaps the piping or some other contaminant, or iron, or debris source.
If you see it mostly at a toilet it could be worth cleaning debris out of the toilet tank too.
he discoloration is only present immediately after a regeneration cycle. Why only in the toilet/tub is unknown. If it were the piping or other source it should be present at all times.
I agree with your reasoning, more or less; sometimes a fixture that runs water faster (like a tub) will stir up and show debris that slower running fixtures don't. A toilet would offer the opposite explanation: debris often accumulates in the toilet tank - in part because the relatively slow fill rate doesn't stir it up enough to flush out when the toilet is flushed.
Start (because it's easy) by taking a look in the toilet tank; look for deposits on the tank walls or crud on the tank bottom; that may point to a water supply debris problem; if there are yellow stains but no deposits more often that points to iron in the water;
With that simple look out of the way and assuming we want to pursue the water softener, I'd check the softner brine tank - in these articles we describe cleaning and disinfecting the brine tank. It's tempting to also run a disinfectant cycle through the water softner itself but I would not do that without knowing the brand and model and then checking the manufacturer's cleaning instructions.
1. checking and cleaning the brine tank
2. running the softener through an extra regen cycle
Toilet tank is clean. Cleaned brine tank, manually ran two regenerations…next scheduled regeneration had no water discoloration…latest regeneration (Today) had the discoloration back in toilet (cleared after 4 flushes).
are we certain that the incoming water from the source is not the origin of the discoloration you're seeing? Have you tested that water - ahead of any treatment equipment?

i get a light powder like residue on my dishes after a dishwashing cycle
I've seen this deposit in more than one circumstance: using too much dishwasher detergent, very hard water supply, and on occasion, debris that needs to be cleaned from the dishwasher bottom.

Just set up new digital water softener. finished settings and run regeneration cycle. It carried out regeneration adn then started cycle all over again ? what is wrong pleaase - what should I do?

have well water system. had a bad algae bloom. water co. said softener had to be replaced. could it have been cleaned, repaired instead?
I'm unclear why a dirty water softener would need replacement; someone is giving expensive advice that's safe for them and costly for you. Instead I would follow the water softener cleaning and disinfection procedure in your water softener's instruction manual or see our water softener cleaning procedure article at

I cleaned my water softner tank and now I can't get the prime back. Please help!
If you mean your well pump has lost prime just search inspectApedia for "LOST WELL PRIME" or "HOW TO PRIME THE PUMP" to see procedural details.
If you mean the water softener is not filling the brine tank you will want to check for disconnected tubing, a clogged check valve, or a clogged or improperly set (e.g. on bypass) control valve.
