Oil Tank Cleaning & Vacuum
Advanced Environmental does not recommend cleaning your residential oil tank and keeping it in service. Instead, we recommend cleaning your older oil tank as part of an overall removal and installation project. See Oil Tank Removal
Typically, if your oil tank has sludge build-up, it is a sign that your tank is older; and cleaning may cause a leak. The reason for this is that frequently the thick sludge on the bottom of older tanks may be the only thing holding the tank together and keeping it from leaking. When the sludge is disturbed by inserting a vacuum hose into the fill pipe, your tank could actually have cracks that were sealed by the sludge and subsequently leak once the sludge is removed.
The only tanks that we recommend cleaning and keeping in service are larger fuel storage tanks with manholes. These tanks allow one of our highly trained Haz-Mat technicians to enter your tank and clean it with great detail.
