I purchased a WaterBoss ProSeries water softener and plan to install it immediately before my water heater as described in this post.
The instructions for the water softener indicate that 3/4" pipe must be used between the water softener and the water heater. However, the existing pipe supplying the water heater (shown in blue) is 1/2".
Is there any reason I would need to step up to 3/4" between the softener and the heater?
I can't think of a reason, but I'm also a novice whose confidence is his weakness.
P.S. Bonus points if you read that last bit in Emperor Palpatine's voice.
