Great job, all!

I appreciate you coming out in this heat, and educating me on my water system, things that I maybe have forgotten. Thank you for letting me know how to bypass the system for my garden.

I Have done business with RT Olson

RT Olsen has done work for me on many properties and has done a good job. I recommend RT Olsen. Bob Olsen so far has my trust and he is very experienced. You cannot trust a lot of these other companies but I have had good experience with RT Olsen on many repairs and replacements.

Mediocre Service

It’s misleading to call it a free leak detection service if all one does is use a moisture meter. When you have a leak it’s pretty evident. “Detecting a leak” means to actually identify where the leak is. Cutting up a bunch of drywall not finding the leak and giving up is hardly work. Incompetence at its best!
