Does College Station have soft water?
College Station's water contains 8.07 mg/L Calcium Carbonate (CaCO3), as noted in the table on page 9, and
is considered "soft." Water hardness is sometimes expressed in grains per gallon, and College Station's water has less than one grain per gallon hardness.

Although electrical scares me, I will DIY simple outlets, etc. but older now, prefer even simple done by Master.Elec friends.
Plumbing has never been fun and our septic pump replacements took whatever fun & ego-accomplishment memories to a dark place, so ALL of this is now Master.Plumb done in 1/3 the time, x2 the quality and MOST important, someone to call/fix it again if required.
So from THAT viewpoint, my first thoughts turn to someone the the biz that knows what/where/how/etc.
