Tank Sump Repair
If your secondary containment tank sump is letting in water or letting fuel out it can be damaging to your fuel system or the environment around the underground tank. CommTank can repair or replace your tank sump if it’s not performing as expected. Water buildup in your tank sump can corrode tank components like submersible pumps, manways, vent alarms, gauges, interstitial sensor housings, test fittings, ball valves, and unions. Leaky gaskets or improperly fitted covers can let sand and salt intrude which corrodes metal more rapidly. Frequently a sump repair can involve simply replacing a gasket or boot. Having a clean and dry tank sump can provide easy access for future tests and repairs to the tank.
Overspill Containment Buckets
Overspill containment buckets, or spill buckets as they are more commonly referred to, are important components of an underground tank. The spill bucket can prevent a release of fuel into the ground during a normal fuel delivery, or catch the fuel during an accidental overfill. A well-designed spill bucket will also prevent groundwater from entering the containment area. CommTank can upgrade or repair your spill bucket so that your fuel deliveries are safe and drips/leaks are contained.
Dispenser Containment Sumps
Dispenser Sumps are installed beneath fuel dispensers to provide access to shear valves and piping connections. They also provide secondary containment for the dispenser in case of a component leak. CommTank installs dispenser containment sumps as part of a new fuel dispenser installation or, when needed, for upgrading an old or faulty sump.
Underground Piping Systems, Double Wall Containment, and Adaptors
Tank fuel supply piping and fuel pipe adapters are the equipment most commonly upgraded on underground tanks. Due to exposure to water or moisture in the air, fuel tank piping can rust if not properly protected. Water in spill buckets can cause fill pipe corrosion, which may cause seizing of the seal adapter and drop tube. In order to prevent the seizing of pipe adapters, it is important to install metals that are dissimilar. CommTank installs quality brass or aluminum parts. Many older tanks have single-wall piping that connects the underground tank to the oil burner, boiler, or generator tank. This piping must be upgraded to double-wall piping to protect against line leaks and spills. CommTank can replace top seal adapters and drop tubes or upgrade the underground tank piping so that your tank meets current state requirements for secondary containment piping. We can retrofit most underground tanks so it meets the new regulations in your area.
