How to choose the correct Complete Riser System.

All Complete Riser Systems are designated by 2 numbers (Such as 20x8 or 24x26). The 1st number is the diameter of the riser the 2nd number is the height of the riser system.

Step 1: Choosing the diameter

The diameter you need depends of the acess hole on your tank. You will want to measure the access hole at its widest point. Please use the chart below to determine the correct diameter for your set-up. NOTE: If your system has a square access hole please use the corresponding column.

  Your Access Hole
CRS Diameter Round (Diameter) Square (Side Length)
16 16" or less 11"x11" or less
20 20" or less 14"x14" or less
24 25" or less 18"x18" or less


Step 2: Choosing the height

The height is up to you. Most of our customer choose the height in order to bring the lid a few inches above ground level. However you can go taller or shorter if you wish.

Riser is extremely solid, well-designed, and well-built. I plan to install once the ground warms to above freezing.

Excellent product. Very easy to install. Did entire job in less than 1 hr. (I however recommend that you use a hammer drill to drill the holes in the top of the septic tank. Regular drill was insufficient.) Riser is very robust and looks great from the surface. Hold the weight of a 250lb man without deflecting. $199 is well worth the money to avoid digging a 3ft ft x 2ft hole every 3-4 years. Wife can now simply call the pump guy in the future. No more work for me. haha..

The riser is really nice quality and easy enough to install. After searching at length for the right thing for our situation, this kit stood out and it was the perfect solution!
