This product works very well. Simply pour down the toilet 1x per month. Has kept septic troubles away for years in our house! So glad Sam’s offers it online.

Love that this box contains 5 months of treatment. Have not found this size elsewhere. The price is low especially compared to other boxes of one or 2 treatments. Great value!

The country life consists of keeping my septic system flowing, and the lg size box of Rid-x makes it convenient for 5 monthly services! The price per treatment is a plus from Sam’s Club!

Septic pumpers have always described my system as one that is "working". I'm sure paper and grease/fat enzymes to help digest these problematic materials incorporated in Rid-X formula are why.

Good product, convenient and economical. I recently started using as another product through the mail was very expensive and was what probably ruined my septic system.

I believe it's working practices I the 4th month since I bought it and I've had a lot problems with my subject tank It's one those things you do and you never sure its working or not working

I brought this & so glad I did, the price is right compare to the monthly boxes. I will only purchase this product from Sam Club for now, shipping was quick, packing was secure & well wrapped to prevent product leakage.

This product is important to use on a monthly basis for all septic tanks. Sam’s Club only carries it online and the bulk size offers a competitive price.

Love using this product know that it works well for me to keep all running through. Love buying the box with several months supply knowing I won’t run out

We aren't sure how well this works, compared with other products, because we have always used it, and we feel it has kept our septic tank from having to be pumped as often as other people's septic tanks.
