Dispenser Containment Manual current installation instructions. 8.2 Long Form 8.2.1 Design The under dispenser container shall be of such a design as to permit access to all associated fittings and valves located directly below an above ground dispenser. The frame of the container shall be sized to fit the framework of the dispenser and permit anchoring of the dispenser directly into a concrete slab. 8.2.2 Product Compatibility All components and accessories of the dispenser container shall be chemically compatible with the products to be distributed and with chemicals found naturally in the ground environment. 8.2.3 Corrosion Resistance All dispenser container components which come in contact with the ground environment shall be made of non-metallic material or protected by materials which prevent corrosion. 8.2.4 Structural Integrity All components shall be designed and constructed of materials strong enough for their intended use. The dispenser containers shall not collapse, crack or break due to ground movement, backfill stress or high ground water pressures. 8.2.5 Pipe & Conduit Entries All dispenser containers shall be fitted with pipe and conduit entry seals which are semi -absorbent to ground movement and sufficiently flexible enough to permit angled entries up to 15 degrees without leaking under liquid head pressures of up to three feet. 8.2.6 Liquid Tightness All dispenser containers shall prevent outside surface and ground water from coming into the container and prevent any product originating from within the sump from escaping into the underground environment. OPW-FCS recommends hydrostatic testing on all sumps after installation to check for proper sealing of joints and connections. 8.2.7 Hydrostatic Testing OPW Fueling Containment Systems recommends the following procedure for hydrostatic testing of dispenser sumps, tank sumps and specialty application sumps. 1) Visually inspect all entry boots for band clamps, compression rings and donuts for possible leak points prior to connecting. Correct as needed. 2) Be sure all test tubes, connector tubes or any other open secondaries into the sump are sealed and liquid tight. 3) Fill all sumps to a minimum of 1" above the highest penetration fitting or sump joint. Mark the liquid level with a permanent marker. 4) Hydrostatic test should be held for 1 hour or per local regulations. 5) Be sure all water is disposed of properly after completing the test. Note: Should the liquid level drop during testing, visually identify Fha*W©Q R KS BY OPW FUELING CONTAINMENT ItYSTEM8 the leak source. Remove water and tighten band clamps to 30 in/lbs. Entry boot compression rings should be tightened in a clockwise manner until each stud reaches 60in/lbs. Repeat testing procedure.
