A Few Testimonials

If you have a septic tank and you want wonderful service to deal with your stinky problems, these are the guy.  They are so helpful and quick to respond to any problems you have.  I had a Priana installed in my septic tanks a couple of years ago and it has been a great solution to my overflow issue… when there have been problems out of normal conditions they have always been right there to help. unt quis.

We first spoke with Gopher when we were considering buying a house that they serviced.  At the time, they spent 45 minutes on the phone with us detailing some of the basics of septic systems and answering questions.  I felt they really wanted to help and impart their knowledge vs. just wanting to get us off the phone, which you might expect.  Our Realtor reinforced our initial opinion, saying that Gopher is top-notch and very well regarded in the area.   Now that we purchased a (different) home, we have a service contract with Gopher for our Piranha system, and we are now a very happy customer.
