Jimmy,
your call...?...But for less than $2.00 you can get the job done........... 8)
I put 1 quart of Vinegar in my
Butlers every month...110 gal fresh water tanks...
Then just clean with it...Cleans out Chemical pump & Chemical feed guage...
Also cleans out your wand valve,hoses,jets,ect......
At that dilution, or even 1 gal....It will only have a minimal effect on your metered solutions.
I HAVE NEVER.....had to DESCALE any of my
Butler Units....in 20 + years... :wink:
