The salt tank overflowed!

Cillit Ruby

Once is not custom ... here I am again faced with a failure on my water softener CILLIT Rubis Bio Intégral 90 ....
The symptom was perfectly visible without dismantling anything, water covered the floor of my cellar!

First usage checks

Faced with this problem, I of course checked the good condition of the connections of the machine in search of a possible leak.
What neni, no leaks on the fittings and other bypass valves. The opening of the salt tank showed an overflow, the water having reached the level of the salt filling hatch!

The first thing to do in this case is to completely empty the bin, and it may take a while ...

  • draining brackish water
    To do this, I used the communicating vessel method using my garden hose. The floor of the cellar being higher than the level of the road in front of my house, I plunged the pipe into the bottom of the tank, and then unrolled it entirely outside in the gutter.
    Warning : this only works if the pipe is already filled with water to be able to start the transfer ... the technique is therefore to connect a closed spray gun on the channel side, and connect the other end to a drawing. Open the water supply then shut it off when the pipe is full.
    Then disconnect the pipe by pinching it if necessary before plunging it into the bottom of the brine tank. Now all you have to do is open the gun to see the sustained and almost regular flow of water ( thank you to my son-in-law for the help he gave me ... )
  • emptying the salt and the brine conglomerate lying at the bottom of the tank
    There is no other choice but to do it manually using a gardening spoon ...
    I recovered the pieces of salt intact in a plastic bag for reuse, the rest going to a recycling center.
  • cleaning with a Kärcher of the emptied container.

Trouble shooting

As in the previous article “No more soft water! ” I proceeded to set up the test procedure , still with a bottle of water placed this time in a large enough bucket (well yes, considering what risk to overflow ... not want to mop the floor again ... )

Well obviously the bottle was filled and ... overflowed but after only several days ...

overflow of the bottle ...

But what's going on this time? the dimension X is however well adjusted to 110 mm ...
I resumed my research on the Internet and saw appearing beyond the term "slow leak" ... let's think about it ...

The device is connected to the water inlet pipe via a pressure reducer set at 3 bars. You will probably have noticed if you have already practiced the question that if you disconnect the gray hose from the brine valve, water is constantly flowing ... This is normal given the constitution of the head softener ( see image 1 ).

It will not have escaped your notice that this pipe used both for filling water and for sucking brine is in permanent connection with the water outlet of the softener head ... and therefore in my case under a pressure of 3 bars ...
Suddenly the small seal ( see image 2 ) which closes the brine valve is put to the test.

In view of the material as well as the particular dimensions of this seal, I could not find a replacement. In addition, it is not said that he is not the only one involved in this story, it is also possible that the body itself of the valve is corroded ... So after very long research I decided to replace the complete valve, ordered from CILLIT and delivered by BWT.

Since my very last and recent intervention, my softener has been working perfectly again, without any leaks whatsoever.


Disassembly / reassembly of the valve

If like me you have found yourself somewhat disappointed in front of this famous valve, I will explain below how to open it in order to check / clean the different parts that compose it.
Before any manipulation, I strongly advise you to take pictures, it can be useful during reassembly if you are in doubt ...

  • Disassembly:
    • the cap forming the base of the valve is quite difficult to unscrew ...
      To do this I held it in a vice fitted with aluminum jaws ( to protect the cap ... ), and thus have loosen ( CAUTION! not completely ) more easily and by hand the valve
    • Once this step has been completed, take the valve in hand and turn it over so that the cap is at the top ...
      Carefully unscrew the cap and remove it. You should see the first red ball which only serves to lock the small part opposite ( see image 3 ) ...
      → to perform the following operations, it is preferable to stabilize the valve well in a support, such as a vise workbench for example ...
      To take my photos, I simply used a spring clip and thus fixed the valve vertically to one of the drawers in my desk ( the clip is visible on the first 2 photos below below )
    • by delicately removing this first ball as well as the small part located just to its right, then you will be able to see the movable joint and a second ball below ( see image 4 ) ...
    • by removing the movable seal, you will then see the second ball housed in the bottom of the valve closing rod ( see image 5 ) ...
    • to release the closing rod you will have to remove the float by simply sliding it until it is released

  • Reassembly:

    • it is quite easy to do, provided you take some precautions ...
    • replace the closing rod, taking care to place the float ( pay attention to the direction of assembly, see image 8 )
      Stabilize the valve vertically so that it can be more easily filled with these different parts, this will only be a simple formality
    • replace the cap by starting to screw it in, then release the valve from its grip and then finish tightening it by hand .

So, the operation is now complete and if like me you need to replace this valve, here is its reference at BWT:

Ref .: P0014854B brine regulator ( delivered without the gray brine suction hose, but with the nut on the base of the valve ... )
                             → count around 86 € HT without shipping costs ( as of date of April 2019 )
