water softeners

[lindsay]

i am looking for the chemical equation for water softeners. it doesnt need to be balances. thank you.

Sodium zeolite water softener? Try searching the web

In cursory review, where z = ion exchange site on the ion exchange resin, we have:

Softening:
CaCO3 + 2 NaZ <==> Na2CO3 + CaZ


Regeneration:
NaCl + 1/2 CaZ <==> 1/2 CaCl2 + NaZ
High concentrations of salt are used to force the equilibrium to the right ...

Any idea why my Kenmore softener suddenly won't go into suction mode?

Perhaps consult your manual.
What makes it go into suction mode? Start there... control problem (no power, turned off, etc?), mechanical problem (no water pressure, etc).

been through it all and all seems fine. Replaced motor recently. Doesn't appear to have any internal wear in the head. Venturi assembly and all seem fine aswell. Cycles correctly and drains fine. Just after the fill cycle, it briefly creates a suction and thats it, probably a spoonful. This hard water stuff is getting old too!

My only thought is a small leak in the line or fitting that allows the filling to occur but isn't allowing enough suction for water, but I don't hear a leak.
