Expert Insights

The drain-equipped 275-gallon model is the preferred choice for outdoor installations with significant rainfall. The drain allows controlled removal of accumulated rainwater after testing confirms it is uncontaminated — this prevents the sump from filling with water and losing its spill containment capacity. The drain must remain closed at all times except during controlled discharge. Always test accumulated water before draining to verify no fuel contamination. The $17 price difference over the no-drain model (A2800U) pays for itself quickly by eliminating the need for manual pumping after every rain event. Both models share identical dimensions and sump capacity.

Frequently Asked Questions

275-Gallon Fuel Tank Containment w/ Drain

When should I use the drain?

Only after testing confirms the accumulated water is uncontaminated. The drain must remain closed at all times except during controlled discharge per SPCC protocols.

Is the drain model more expensive?

Only about $17 more than the no-drain model. This pays for itself by eliminating manual pumping after rain events.

Does the drain affect containment capacity?

No. The 360-gallon sump capacity is identical to the no-drain model. The drain simply provides a controlled way to remove clean rainwater.

Can I plug the drain permanently?

Yes. If your site regulations change, the drain can be permanently plugged, converting it to function like the no-drain model.
