Dan, I avoid drilling into the walls as much as possible and use velcro and adhesive hangers when possible. But when they won't work I'll drill, but as carefully as possible. I have a stud finder that will locate 110 volt electrical lines when they are "hot". It is made by ZIRCON and is the STUDSENSOR PRO SL-AC. works great. For water lines you just have to be careful. Good luck.
John
