A poorly maintained funnel or latching lid won’t function properly or fulfill its purpose. According to an EPA guidance document issued to regional directors, “EPA considers the container closed when the cover makes complete contact between the lid and the rim all the way around the top. Having a tight seal prevents VOC emissions. Generators should be aware that the seals on containers can erode because of time and use, and should be checked periodically for wear and replaced if necessary.”
Below we’ve listed the steps to maintain a tight seal for as long as the unit is in service. Plus we’ve thrown in tips to keep the liquids flowing.
- Clean up material that spills on the rim. If it builds up it will prevent the lid from sealing uniformly around the rim or could glue the lid and gasket to the drum, causing damage when you pry it open.
- Replace lid gasket as needed. Over time chemicals will degrade the gasket preventing the lid from sealing. We recommend a gasket kit for your drum lid.
- Oil the enclosed pivot mechanism on the handle on a routine basis to prevent excessive friction and wear.
- If equipped with an overfill preventer, make sure vent holes are open and free of any obstructions.
Latching Lids Tip
- Make sure the band is at the uppermost part of the drum securely under the top chime. Adjust the latch as needed. Binding and misalignment will make it hard to seal the lid and could possibly bend the assembly.
Follow these steps and your lids and funnels should keep working for a long time.
