    Default sparkling water??

    I have a Kenmore softener, about 1-1/2 years old. I have had no problems with it prior to now.
    Several mornings ago, I was surprised when I opened the kitchen faucet and the water was super foamy. It would foam up like crazy in a glass, like it was carbonated water. The foam in the glass would quickly die down and the water was fine.
    I called the water company and they came immediately but said the water at the street was fine and not foamy at all.
    I checked the water softener and noticed it had about 18 inches of brine in the tank where it usually has none or very little.
    I cleaned the orifice and manually regenerated. It drew the brine down as it should. I noticed nothing unusual with the regeneration.
    The next morning the "sparkling" water was back.
    I can only assume air is somehow getting into the system and being absorbed by the water under pressure and then the air comes out when it is at low pressure at the faucet.
    Has anyone seen such a problem before?
    Is it likely to be seals in the brining circuit?
    Should I dismantle the whole thing and replace all seals?
    Is there another reason for the foam?
    I hope someone has seen this before.

    Have you checked to see if the water is salty? I have seen saty water foam up the way you describe.

    Nope, not salty. The water is perfectly fine once the foam dies down.

    Do you mean foamy like dish detergent etc. or just a lot of small bubbles? If small bubbles, remove the faucet tip aerator when this happens and see if the bubbles don't stop. Don't lose parts of the aerator, lay a dish towel etc. in the sink so none can get gone if you drop any.

    If after removing the aerator clears the water, then the city water pressure may be higher than normal and faucet tip aerators are supposed to add air so that would be your problem. A water pressure gauge with a recording finger installed on a utility sink or outside faucet overnight would tell you how high the pressure is and if you need a pressure regulator valve or if you have one, if it is bad.

    If the water wasn't clear after removing the aerator, then you may have a water leak past the softener, causing water to flow while in a regeneration but foamy water from the softener should taste salty.

    The bubbles in the water are super tiny so it is foam more like the head on a glass of beer. Initially, when I fill a glass of water, there is a "head" on the water, but after about 5 seconds, most of the foam is gone.
    I see no foam at the outside faucets so I agree it has something to do with the aerator.
    I have been using the softener for a year and a half and this phenomenon just started for the first time on Sunday morning, 2/5.
    By tonight, I expect the foam will be gone and I won't see it until the next regen, or at least that is the pattern so far. It regenerated Saturday night (2/4) and I regenerated it manually last night (2/9). It seems there is a connection to the regeneration somehow but the water is not salty that I can tell.

    Garys suggestion on the aerator is excellent and often overlooked. High pressure and aerators = problems. If the water pressure is over 80 PSI (UPC CODE), then as Gary said, a regulator must be installed or repaired.

    Another item to check is the air check in the brine tank. This device is designed to prevent the water softener from sucking air in when the brine tank when the brine water is depleted. A string from a salt bag, a piece of wood from the pallet, or just about any other piece of debris can cause your aircheck to leak by. You should remove the aircheck, clean it well, and then do a quick suction test. This is not overly sanitary, but it is effective. Suck on the tube like a straw after it has been carefully cleaned (you may want to sanitize it and rinse it very well before performing this test). It should not allow any air to enter. If it does, repair or replace it. Systems without a second backwash are particularly susceptible to this problem.

    Let us know what you find.

    Default Water is Salty.

    I have a 12-yr old Hague 23 BAQ.

    My water comes out foamy AND salty a few times per month. After purging, by leaving the taps open for 10 mins or so, the foam/salt goes away but the water has a disgusting "metallic" odor for a few more minutes.

    Any idea what causes this, and what the resolution is?

    Thanks,

    Marco

    Improper rinsing of the resin during a regen. Check the drain flow control and the drain line for a restriction. Do you have iron in the water? If so, it may clog ports preventing proper rinsing. Also, if the brine tank is slowly filling with water between regens, the unit will remove all the water during a regen. If this happens, you may get salty water after a regen.

    Thanks for the response mialynette2003

    Check the drain flow control and the drain line for a restriction.
    There are no restrictions in the line. I don't know how to check the drain flow control.

    Do you have iron in the water?
    I don't know, is there a way I can test for iron?

    if the brine tank is slowly filling with water between regens
    Currently the control says 620 gals till regen and the tank is approx 3/4 full of water & salt -- the water is a few inches above the salt. I have noticed the tank being full of water when adding salt, causing the excess water to overflow the tank.

    The drain flow control is located where the drain line connects to the valve. It is a small rubber button that control the amount of water passing to the drain. If you are on well water, you may have some iron. If you are on city water, I would not exspect you to have iron. If you disconnect the brine line from the valve while the unit is in service cycle you can see if it drips. this drip will increase the level in the brine tank and when it regens will pull all the water out and not have time to properly rinse.

    I have a drawing of the valve that will show where the drain flow control is located. Send me an e-mail and I'll send it to you. affordablewtr@aol.com
