I have to drill some holes through one side of the garage floor concrete from water heater tank to utility sink in attached photo. It's for completing a termite prevention project. My electric, CATV, and phone connect to boxes on outside wall of house. I assume those don't go under slab. The lateral sewer clean out is under concrete step a few inches left of the bucket with the Lowe's logo at water tank cubby hole. Sink and water heater tank plumbing go into wall or ceiling. Hose bib outdoors is opposite garage sink. Is any other plumbing or sewer vent likely to be under garage floor? I might just drill very shallow to be on the safe side. Won't be as effective for termite prevention I know I alone am responsible for avoiding any underground plumbing lines. Somehow, I'll figure out a way to find out if anything else is under there. Any thoughts on where I might drill holes...................through the elevated step, expansion joint below step, other?

Could someone please tell me by pictures what size valve is this? In coming from pipe and outgoing to washing machine. I think they are 1/2 incoming and 3/4 outgoing. [ATTACH]93739[/ATTACH] [ATTACH]93740[/ATTACH] There are thread on incoming pipe. Are these threads on the pipe and there is an adapter soldered to pipe. What kind valves should I replace with? I have these [URL]https://www.homedepot.com/p/Tectite-1-2-in-Brass-Push-to-Connect-x-3-4-in-Male-Hose-Thread-90-Degree-Washing-Machine-Ball-Valve-FSBWMAV/302161124[/URL] I have 3 questions. Q1. Are ball valves any better in terms of functions (not leaking) and longevity over globe vales (what I currently have)? Q2. New Valves are sharkbite valves [URL]https://www.homedepot.com/p/Tectite-1-2-in-Brass-Push-to-Connect-x-3-4-in-Male-Hose-Thread-90-Degree-Washing-Machine-Ball-Valve-FSBWMAV/302161124[/URL]. They require smooth pipe. How should I do it? Should I buy a female adapter like these [URL]https://www.homedepot.com/p/Everbilt-3-4-in-Copper-Pressure-Cup-x-FIPT-Female-Adapter-C603HD34/100347144[/URL] and these [URL]https://www.homedepot.com/p/1-2-in-Brass-CSST-x-FIPT-Female-Adapter-11-435-005/203073898[/URL] Q3. If yes then what size should I buy? 3/4 incoming water side and and 1/2 towards sharkbite valve? Do I need to buy a new box to get a better access to pipe? additional enlargements....
