Tank fills up...

**Why did I try this?** · 09-03-2012, 08:01 PM

Hi,
My water softener tank fills up more than what goes out. I have no float in the brine tank. I cleaned the screen,jet,ball etc.Put in a new dial that regulates the amount of salt used, but nothing has changed. The water does taste like salt quite strongly after a cycle for awhile. Is it possible replacing the paddle gaskets would help? O, the thing is like 36 years old.

LOL, I can assume this is an old Autotrol model 155. You can still but the upper module, but if it is 36 years old, it may be time to upgrade. Please post a picture of it. What color is the plastic? I assume the body plastic is either grey or yellow. If it is the transluscent yellow, I want it for my museum.

The control is a 1550-TC black. There was another sticker that said Marlo DUA-940

If the valve body is black, it should be considerably younger than 36. Since it is black, a rebuild kit would be a good idea. The flappers are good for 5-20 years typically. They are fairly easy to rebuild. Do not use power tools to remove the #2 screws, use only a hand held screwdriver and do not overtighten the series of screws.

Good luck!

I was guessing at the age since everything else in the house seems to be original

Would worn flappers cause the brine tank to fill-up? Or should the tank have a float?

Thank you much

That system doesnt even have an aircheck in the brine tank. It uses the clear canister with the float to act as its aircheck. No float is needed in the brine tank as long as if a failure were to occur, no water damage will happen.

An overflowing brine tank can definitely be caused by a bad flapper disc set, replace them and you will probably be good.

IIRC, the date code is stamped on the valve base in white. If you notice, the upper module can be removed by removing the red clip (dont do this) the date code should be down low. Autotrol used a 5 digit date code, the day of manufactuing followed by the year (I think) so 01388 would be the 13 day of 1988.

See if you can find the date.

Good luck!
