32yr old water softener -options?

Very hard municipal water: 320mg/l (18.7gpg) hardness
32,000 grain softener
AUTOTROL 1550-TC (155) Control System
Regen settings: every 3 days at 7lb salt
Resin replaced 2001.
2 bath home, 2 inhabitants. (System and settings from before empty nest)
Salt: approx (35) 40lb bags annually ($200) -seems like a lot of salt for the settings.

The Autotrol 155 developed a slow leak: Options = rebuild (parts @$100) or replace.
Based on 32yr being beyond expected 20-30yr life, considering replacement:
$252 for 255 Upper Valve Module w/Timer Assembly AP4001226 (Autotrol K-5 upper valve body and timer assembly)
Replace everything while I'm at it, or just the valve body/timer?
Appears a 20,000 grain unit could now be adequate, and a demand-initiated softener may only need (1) 40-pound bag of salt every 68 weeks with a regen every 5-10 days(?) That's far less salt than now.

Was considering bypassing the unit to determine impact the hard water has, then possibly leave bypassed.
Apparently this degree of hardness is generally considered to require a softener (ie: bypass = bad idea).

Appreciate the trouble-free long-life this softener has provided, and goal is same going forward.

Any feedback regarding best option?

Thanks for your time!

Now might be the time to change the valve from day to meter.
You might be able to find an Autotrol meter valve to marry up to the bypass and take the same size distributor that you already have in the tank.
Spending some money on the meter valve will save on the salt in years to come.
