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.
Water not draining from brine tank?
Dan:
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
Joe,
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
Angela
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
Linda,
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.
