Frequently Asked Questions

How often should I get my septic pumped?

It depends on usage, but in most general households, once a year should be enough.

Why does my system back up?

There are many reasons for septic system backing up. These include blocked pipes, full tanks, poor drainage and in extreme cases, you may need a new system. We can help identify and correct your issue.

Does it smell when you pump my system out?

Yes, you will likely smell an odor when your tank is opened up. This smell usually dissipates quite quickly once the system is sealed back up again.

If you speak to our technician when he is pumping, note where he is standing, and stand near him because he knows where not to stand!

Can I add bacteria additives to my system?

Yes, this is a good idea to help keep your system in good working order. When we come, we can advise best products and amounts based on your system.

What maintenance should be done on my system?

Keeping your system in good working operation is vital and if you see any issues, contact us as soon as you can as a small problem could become a big problem quickly. Annual pumping, keep hard waste to a minimum, do not put oils or fats down your system are basic things you can work on to help your system remain operational.

It was time for our regular septic tank drain and maintenance. I called several companies in the area and Denny's quoted me the best price. We bought our home a couple years ago and have never had to contact any kind of septic company on the past. They had a cancellation and offered to give me the slot same day!!!!! The guys came out in the afternoon. The two gentlemen who serviced my tank were incredibly knowledgeable, kind, and straightforward. I am genuinely sad I didn't catch their names. My service agreement is signed JB. I highly suggest their services. They were not only kind, and knowledgeable, but also quick, and efficient. We will absolutely be using their services in the future. Thank you Denny's, and thank you to your service men.

Got a septic pump. It went great. I've eaten at Denny's restaurant and figured they would know a thing or 2 about waste removal. 5 moons over my hammy. Would use again.
