Spill Bucket Testing
Hydrostatic or vacuum testing for compatible spill-containment equipment.
Manufacturer-certified · Testing UST & AST systems since 1997 · Serving 13 states and expanding
Spill containment integrity at every fill port. Single-wall and dual-wall spill bucket configurations.
Testing Method
PTTI selects hydrostatic or vacuum testing according to the spill bucket’s configuration and the applicable procedure. Hydrostatic testing evaluates containment using water. Where vacuum testing is applicable, vacuum is applied and evaluated to the manufacturer’s specifications. Required test periods and acceptance criteria follow the applicable procedure.
- Equipment
- Hydrostatic or vacuum test equipment suited to the installed spill-containment system.
- Frequency
- Where periodic tightness testing is required, the federal baseline for regulated UST spill-prevention equipment is at least once every three years. Requirements depend on the equipment, monitoring arrangement, and jurisdiction.
- Deliverable
- A test record for the spill-containment equipment tested.
Common Spill Bucket Failure Modes
-
1
Cracks or Damage
Visible bucket damage from impact, weathering, or age.
-
2
Drain Valve Leaks
Drain-valve seals worn, or the drain valve not holding.
-
3
Water and Product Accumulation
Standing water is required to be removed from all spill buckets.
Spill Bucket Testing, frequently asked.
What is the difference between hydrostatic and vacuum spill bucket testing?
Hydrostatic testing uses water to evaluate containment. Vacuum testing evaluates compatible equipment to the manufacturer’s specifications. PTTI selects the method for the installed spill bucket.
How often do spill buckets need testing?
Where periodic tightness testing is required, the federal baseline for regulated UST spill-prevention equipment is at least once every three years. Requirements depend on the equipment, monitoring arrangement, and jurisdiction. PTTI tracks the cycle per site so it lands with the rest of the containment-tier testing.
Why is there a water disposal charge on hydrostatic testing?
A charge is applied because water must be disposed of at the proper facilities. The cost is for travel and wastewater disposal. The water disposal charge is $15 per bucket.
