We bought our home out of foreclosure several years ago. We did not have any idea as to the previous care and treatment of the septic system. Since the house had set empty for a year, we felt fairly safe in assuming the septic system had been neglected. Since the system appeared to be working appropriately, we began The Flush-It Septic Energizer monthly treatment plan. I drop it into the toilet at bedtime on the first of each month. We have never had bad odors, sluggish drains, nor leach field issues. I account this to the scheduled maintenance program. This year, we planned a septic tank pumping, however the service agency recommended “not this year” as the system check was in great working order. Thank you Solutions Unlimited for making such a super product. I give you an excellent to septic tank maintenance products.
