Tuf-Tite Septic Tank Riser, 24''x12''

True it has no screws but I have no idea how they would ship it with them. This thing is big.Installed it quickly and easily after buying two inch stainless steel screws at a local hardware store. Fit like a dream with what was installed over 20 years ago.

Got this for my rental septic tank. Great fit, easy to install.

Well made risers to reduce amout of digging to service septic systems. Ordered through Amazon since Walmart messed up my order for the same items. Not once but twice. Amazon is 100% for all my orders.

Worked perfectly. Risers do not come with lids, need to order separate.

Bought this extension for the sewer riser I was installing. Worked well.

muy buena calidad y el precio mejor que en un plumming supply y llego super rápido

Easy install but be willing to endure working around an open septic tank.

If you can dig up your septic tank's lids, apply some goo, and mix up a small batch of concrete, you can handle this. Roofing asphalt in a caulking tube is required to seal between this and the ring that actually goes onto the septic tank. Then you apply a goodly amount of this goo to the bottom of the ring before sticking it down Concrete screws really aren't needed, but you can use them if you like.I noticed that with asphalt, there's a chance of tree roots finding their way through all that and into the septic tank. To fix that, I'll be digging up my risers and exposing the concrete tank again. Then I'll seal up any gaps I missed and pour over that some concrete to a few inches away from the interface between the adapter ring and the tank itself. These parts are full of waffle-like protrusions that provide lots of places for soil or concrete to grab onto. So, count on adding concrete to the outside to make good and sure that no roots will get in. Two bags of concrete should be enough.
