Polylok20" x 12" Septic Tank Riser

It's difficult to "love" a septic tank riser, but that said, this did exactly what I needed. Project was actually a repair to a sump pump. The 20-in diameter concrete sump had been buried 18-in below ground and then stupidly bricked over by the previous home owner. So when the pump eventually failed, we had to jackhammer it open for access and repair. I wanted to extend the sump to ground level and have a lid. I used these PolyLock risers and a lid to extend the 20-in diameter concrete sump pipe level to the surface (BTW, I tried getting just 18-in of the concrete pipe, but it is sold in minimum 10-ft lengths that would need a small crane to move). Anyway, project came out great.

Great product! Came with gaskets and screws. Genuine. Fitment was great.

We had to buy a new one cause the old one was busted. It fit perfectly. And works amazing

The lids compatible with these risers come with hardware.... these extensions do not. Just be aware to order hardware separate. If these risers are attached with no hardware standard dirt settling will detach these and damage your system over time. Great product... but the screws are 100% required.... so it's odd their not included.

Product fit fine and these risers are hard to locate. Would have liked a set of screws as you need d square stainless steel.

Wow; received these in 2 days after ordering. Risers are well built and already have a gasket installed on the bottom. Very easy to install. These came with 6 stainless steel screws for each riser ; however they are Phillip head screws; square head screws would have made install a little easier; All in all ; I am very happy with the risers; took less than 10 minutes to install . Thanks for a great product.

Way easier, less expensive and delivery to my rural location a huge plus

I got it right on time, and worked great for my project

Came quickly fit perfectly
