What Our Clients Say

Hear from customers who trust M-1 Tanks

Easiest review I've ever done... From owners to bookkeepers to drivers to shop managers….everyone cares. They make the installers job really easy. They really do. Jim has walked me through multiple different designs and got me lined out and ready to go. Great team and very consistent.

Jake Gann

Gann Construction

I have been using M1 Tank products for over 25 years. I have never had a problem with any products or service. They are one stop shop when delivering septic systems to the job site. The time savings they bring to the job (all the material to complete a septic system) means I don't have to run around and find it at other pipe stores. If all companies ran this efficiently my life would be easier.

Steve

Desert Winds, Inc.

M1 tanks has been more than helpful. Their product and service it's truly above and beyond. I can't say enough good things about the staff and the owner. Always willing to help and adjust schedules when needed. Jim is so full of knowledge. M1 will always be my go to supplier for septic tanks and materials.
