My own personal home and one of my higher end homes has acid stained and sealed concrete.

One is called Hair and Grease, it comes in a bag as it's an acid product-so consider your pipes and the environment.

Grind all concrete with a diamond wheel, don't use the acid etch.  

I think she would magically become more helpful after that.Also look into enzyme products then possible muriatic acid then kilz sealer

A savvy architect, knowledgeable of both building and fire protection codes, with the energy to muddle through the process, could prove to be very valuable.And since the sprinkler piping was installed in the attic spaces, we used a glycol system to prevent freezing.What's driving the requirement for a second water line... is the existing line too small to handle the sprinkler demand or do they want the lines isolated?  

@Jacob Murphy the cat pee is the worst because it is very acidic.

I cleaned hideous toilets back to virtually new in a few minutes using pool acid.

Many people sleep on their sides to mimic the fetal position but the problem is you toss and turn because pressure is put on the shoulder.With a motorized bed you can elevate the legs which takes pressure off of the spine and back and with the upper body elevation you keep reflux from happening from the stomach into the throat which also helps the sinuses drain properly instead of pool and swell the turbinates at night causing congestion and difficulty breathing.The zero gravity position from a motorized bed mimics the fetal position but opens up the lungs for better breathing and keeps the acid down in the stomach plus since you are not on your side the pressure is not on the shoulders.When you first try it there is some getting used to as your body has been out of whack for so long.    

That can be cleaned off in a couple of hours by a guy with a brush, a ladder or scissor lift, and some acid and water.I don't think that's a big deal.I wouldn't waive anything until after the inspection, however.

Don’t go looking for additional stomach acid, because you’ll find it.
