Assmann polyethylene tank maintenance schedule and check list.

  1. Never enter a tank without following OSHA approved guidelines.
  2. Check each fitting monthly for possible seepage or leaks.
  3. If you detect some seepage, tighten the bolts or the compression nut slightly. Do not over tighten.
  4. If tightening the hardware does not solve your problem, you may need to replace the gasket or the complete fitting.
  5. Flush your tank every 12 months. This will help to prevent premature failure due to buildup or oxidation. Do not flush the tank with anything that may cause an exothermic reaction. Check with your chemical supplier for a solution that can be safely used to flush.
  6. If your tank is five years or older, check the inside and outside surface of the tank for crazing, cracking or unusual discoloration. Focus around fitting areas. If you do not find anything, you should check the tank every year thereafter. For chemicals like sulfuric acid,
    sodium hypochlorite, sodium hydroxide or other known stress-cracking agents, check the surface area after the second year in service and every six months thereafter.
  7. Stress cracking is a warning sign that should not be ignored. If you suspect or see any signs that could be stress cracks, call your United States Plastic Corp or Assmann Corporation direct.
  8. Make sure all flexible expansion joints are in good working order.
  9. Do not allow the individual responsible for filling the tank to surge air into the tank after filling is complete. This tank is not a pressure vessel. Do not use more than 7 psi when clearing fill lines.
  10. Keep a log of all inspections.
