## Description

Polylok 24" x 12" Septic Tank Riser w/Wall Flats - desertcart.com

Review: Quality risers. - Great product easy to assemble easy DIY.
Review: Great product and great price! - After figuring out the previous owners had only installed a 6 inch riser i decided to increase the height and replace our damaged lid. Luckily this was the same product as what was allready there and a direct replacement. Installation was as easy as placing the new riser on top of the old one and screwing it into place. The lid fit perfectly and has a rubber gasket for a good seal. No more digging 2 and a half feet to get to my lid!

### ⭐⭐⭐⭐⭐ Worked as well I I hoped!
*by L***S on May 21, 2019*

These are stackable, and qty 4 Allowed me to create two 24” deep access portals to my septic tank. I recently installed an aerator so having Easy access to the tank to monitor this system was my aim. I only installed 12” and the lids in the beginning and finally decided to add more dirt to level off my yard so I added 2 more 12” to the existing risers. I was pleasantly surprised that the stacking/nesting seal at the joint works as well as tight as the lid seal, and mounting ring seal. I bolted this to tank and everyone says Bhutl tape was the way to go but I found it hard to work with, and ultimately a failure. (Installer issue I’m sure) I just sealed it up it “great stuff” Expansion foam’ we’ll see in a year or so if that w a mistake- it looks good now, but it’s only been 60 days
