FLECK® 9000/9100/9500 Service Manual. 3 INSTALLATION & START-UP Water Pressure A minimum of 25 pounds (1.7 bar) of water pressure is required for regeneration valve to operate effectively. Electrical Facilities A continuous 115 volt, 60 Hertz current supply is required. Make certain the current supply is always hot and cannot be. Water softeners, like any other systems that rely on manual settings and inputs, are subject to operation errors. If your system is particularly complicated and you don’t have the technical knowledge to set it properly, there are countless things that could go wrong. CAUTION: The inlet water temperature MUST NOT exceed 1200 F. Do not locate softener where ambient temperature drops below 400 F. Allow space around the softener for ease of servicing. The softener drain lines must never be solidly connected to the sewer line. (Always provide an air gap at the END of the drain line). Valve drain line.

Water softener brine tank troubleshooting when the brine level or water level is too high:

Too Much Water in the Brine Tank - Diagnosis and Cure

The water level (or briny water or brine level) in a water softener brine tank may be abnormally high, or it may simply fail to drop when the water softener goes through a regeneration cycle.

Here we list the common causes of these two conditions, followed by a diagnostic table, followed by step by step suggestions of parts to check on the water softener and its brine tank.

In the article below we will explain how to find, remove, clean, fix, or replace each of the water softener parts involved.

Watch out: in some water softener designs, too much water in the brine tank will send too much brine through the water softener resin tank during the regeneration cycle.

If that occurs your water may feel too slimy (too soft) and may contain excessive salt.

Brine Tank Water is Too High: common causes of weak or incomplete brine draw

Water softener injector or eductor is clogged or plugged: remove and clean it.
Or the nozzle and venturi that produces the pumping suction for the system are not properly seated.
See EDUCTOR REPAIR in this article.
Water softener valve seals are leaking
Water softener piston assembly is damaged or worn: replace the parts.
See our discussion of control head pistons in the table at BRINE TANK DIAGNOSIS & REPAIR
Water softener drain line restriction: the line i skinked, plugged, or leaky: inspect and replace the drain line as needed
See WATER SOFTENER PLUMBING PROBLEMS where we discuss problems with the water softener drain lin
Water softener drain line is routed too high, too far, of too-small diameter, or building water supply pressure is too low, thus combining to exceed the softener's drain lift capacity
Water softener brine valve or tubing is clogged, stuck, obstructed
Water softener backwash flow controller or drain line flow controller (DLFC) is clogged or closed: check, clean, or replace the part
See DLFC LOCATION in this article.
Water softener brine line float controller is stuck, damaged or clogged: replace the part.
See WATER SOFTENER BRINE TANK FLOAT LEVEL ADJUSTMENT
Also see WATER SOFTENER PLUMBING PROBLEMS where we warn about crimped tubing or leaky tubing between the brine tank and the water softener control head or resin tank, causing weak brine flow due to crimps, blockages, or air leaks.

Where are these parts? Below we include drawings or photos showing the typical location of these parts but you'll want to check the parts diagram for your specific water softener brand and model.

Brine Tank Water Does Not Draw Down during Regen

Water softener injector is clogged: remove and clean the injector
See EDUCTOR REPAIR in this article.
Water softener piston assembly is damaged or worn: replace the parts
See our discussion of control head pistons in the table
at BRINE TANK DIAGNOSIS & REPAIR
Brine line tubing or connectors between water softener and brine tank leaky or crimped: inspect and replace as needed.
See WATER SOFTENER PLUMBING PROBLEMS
Water softener drain line clogged or too small or too high, causing backpressure: inspect, repair, re-route, replace the drain as needed. A drain routed more than 8 ft. above the softener or more than 20 ft. in length is likely to give trouble unless extra steps are taken such as using a larger diameter pipe and possibly an ejector pump.
See DLFC LOCATION in this article for notes about the drain line flow controller.
Also see WATER SOFTENER PLUMBING PROBLEMS
Water supply pressure too low: compare inlet water pressure to the water softener to the specifications in your water softener's manual.

This page only discusses repairs pretaining to excessive or too-high brine levels in the brine tank of a water softener.

If you are unsure about the purpose of the water softener brine tank and brine usage during water softener regeneration cycles,
see WATER SOFTENER OPERATING CYCLES for an explanation of the preparation, draw, and use of brine from the salt tank on a water softener.

Reader Q&A about Brine Tank Draw Cycle Troubleshooting

On 2020-05-13 - by (mod) - sorting out why brine tank does not draw fully down during softener regen

If you hear water being discharged by the softener into drains and there is NO brine being drawn down in the brine tank, depending on where the softenr is in its cycle, that may be perfectly normal.

In some phases the softener is drawing some house water and rinsing the tank into the building drain. Not all of the rinse cycles use brine.

Ok I understand.in trying to figure out the issue, I guess what I’m not clear about is why during the draw brine stage I can hear water drawing into the septic pipes, even though the brine tank water level doesn’t go down at all.. is that water coming from the resin tank?

On 2020-05-13 - by (mod) - what should be taking place when the regen phase is supposed to draw brine?

Sure, Sam, thanks for asking.
Some water softeners use a longer, more complex series of steps but they're all doing about the same thing.
During the water softener regeneration cycle there are a number of steps that basically
