If any suspect <br /> areas are found,they would be brushed with the soap and water solution to see if any bubbles develop. <br /> This letter certifies that even though the tank pre installation air/soap test was performed at 3psi <br /> instead of the required Spsi,the 3psi air/soap test is adequate for the 8'-12000&8'-6000/6000 DWT6 <br /> hydrostatic annular space tanks on the referenced project. The warranty will be in effect as originally <br /> provided by Containment Solutions at the time of the tank delivery. <br /> This variance is for the referenced installation only. All future tank installations should follow the <br /> guidelines published in the CSI installation Instructions Pub No. Inst 6001. <br /> Thank you for using Containment Solutions fiberglass underground storage tanks for your project. If you <br /> have additional questions about any of the information provided, please let me know. <br /> Sincerely yours, <br /> Kevin A.
