Limitation: Slightly taller installations may require more careful fitting of adapters and screens during setup.
Aero-Stream AS-R23 Septic Tank Riser Kit
Best for deeper tanks where a taller riser is advantageous. The AS-R23 kit extends access height to 23″ with the same ground-level goal as smaller kits. It uses rugged HDPE components and is designed for reliable performance across seasons.
Who it’s best for: Projects needing increased access height for difficult-to-reach lids.
Why selected: Offers a higher riser for deeper applications while maintaining user-friendly maintenance access.
Limitation: Taller assemblies may require additional clearance around the tank to avoid contact with surrounding structures or soil.
Buying Guide: Key Considerations For Choosing A Plastic Riser
Risers should match tank diameter, height needs, and installation environment. Consider the following:
- Most residential tanks use 23.5″ to 24″ diameters. Confirm your tank’s opening size before purchasing.
- Determine how much ground-level access you want. Stackable options offer flexibility for future height increases.
- HDPE and LDPE are common for weather resistance and UV stability. Ensure chosen model is rated for outdoor use.
- Some kits include screws, rings, and safety screens; others require separate purchases. Check included components.
- Ground-level access should allow easy lid removal, inspection, and pumping without tools heavy lifting.
- If you anticipate needing more height later, select a kit that supports stacking additional risers.
- Confirm that chosen components comply with local septic regulations and that any warranty terms are understood.
Frequently Asked Questions
- What diameter should I look for in a septic riser? Most residential tanks use 23.5″ to 24″ openings; measure your lid diameter to confirm compatibility.
- Are plastic risers durable in cold climates? Yes, many HDPE risers are designed for all-weather performance, but check temperature ratings for extreme environments.
- Can risers be added after installation? Yes, modular and stackable designs allow height adjustments without replacing the entire system.
- Do all risers include installation hardware? Not always. Some include screws and rings; others require you to source hardware separately.
- Is a larger diameter better? A slightly larger diameter can provide more lid clearance and reduce rubbing, but must match the tank opening.
- What maintenance benefits do risers provide? Ground-level access speeds inspections, reduces excavation, and simplifies lid removal for pumping.
