Schematic diagramming software.

I'mI'm looking for a program for diagramming plumbing and electrical schematics. Doesn't have to be too fancy I don't mind paying for it. I'm not going to be publishing with it so to speak. When I was still working for the Navy I used to use Vizio and I was very good at it but it has become bloated in his more focused on flowcharts Etc rather than schematics. Do you have any recommendations I'd love to hear them
