Hi I am a newbie to Water softeners. THis model says it is “Deluxe Valve designed for homes with up to 1″ plumbing” but the plumber who came to install said this is 3/4 inch softener and I need 1 inch softener as my hom has 1 inch pipes. DO I really need to buy 1 inch softener. Is this model work with my pipe. I have a 3 BR single family with 3 and half bath. Myself, my wife and 5 yr daughter.. I looked and I do have 1 inch pipes. So based on the hardness which is 7 .. I thought 36000 grins softener is more than enough.. Why I cannot connect 1 inch pipe to my softner though bypass valve ( i think this is 1 inch ) and 2 copper tubes ( 3/4 inch ). All these came with the softener I bought at Sears
.
