I have some extra septic tank parts that I ordered by mistake. I have 1) 24" Tuf-Tite Septic Tank Adapter Ring (Brand new cost me $51.32) selling for $45.00 I have 1) 24"x12" Tuf-Tite Septic Tank Riser(new costs $59.36) selling for $55.00 and I have 1) 24"x6" Tuf-Tite Septic Tank Riser (brand new cost ($46.63) selling for $40.00. Now if you wish to purchase all 3 together I will make a deal of $125. Or if you want to purchase the adapter ring and the 24x12 riser that is $100.00. If you wish to purchase the adapter ring and the 24"x6" riser that is $85.00. These are brand new , we did not use them at all. Had them on hand just in case.
