Installation Requirements for Cone-Bottom Tanks
Steel Stand or Skid
Always mount cone-bottom tanks to a stand — never directly on concrete or gravel.
Flexible Fittings
Prevent stress cracks by using flex couplings between tank and plumbing.
Ventilation
Install a proper vent system to avoid vacuum collapse during drainage or fill cycles.
Anchoring
Cone tanks over 500 gal installed outdoors may need wind/seismic anchoring.
Common Questions About Cone-Bottom Tanks
- Can I store drinking water?
✅ Yes — choose NSF/ANSI 61 certified models made from FDA-grade HDPE. - Do I need a stand?
✅ Yes — cone-bottom tanks must be used with a steel stand or cradle for full support. - What’s the best cone angle?
🔧 45° for general use; 60° for sludge-heavy or settling applications. - Are these tanks outdoor rated?
☀️ Yes — black and green models are UV-stabilized for outdoor use. - Can LibertyCES install fittings?
🔧 Absolutely — ports, sensors, gauges, and valves can be factory-installed or configured. - Is this safe for chemicals?
🧪 Yes — use XLPE tanks for aggressive chemicals, and we’ll spec the correct resin for you.

Installation Must-Haves for Cone-Bottom Water Tanks
-
Steel Stand or Skid
Supports cone weight and shape – tank must not sit directly on ground. -
Level, Solid Base
Concrete pad or grating to prevent tilt or stress. -
Flexible Plumbing
Use flex fittings to prevent cracking due to expansion or vibration. -
Venting System
Protect against vacuum collapse during fast drain or fill cycles. -
Anchoring / Restraints
Required for outdoor, mobile, or seismic zone installations. -
Drain Control Valve
Allows precise flow management and sediment release from cone tip.
