with positive shutdown. By installing a second sump probe we have provided a more <br /> reliable secondary means of line leak detection, because the sump probes are more <br /> reliable and accurate than the mechanical line leak detectors. I have removed UST's in <br /> the past which had line leak detectors and holes in the product piping. <br /> Proposal 2 <br /> Remove one line leak detector and add one 4" valve. Since the lines from each pump <br /> are teed together anyway, one line leak detector proves the entire underground line <br /> coming from both pumps. The second line leak detector is not doing anything except <br /> proving the 6" steel line in the sump between the pump and the swing check valve. This <br /> would remove the problem with opening both lines simultaneously and gradually. <br /> In summary, please review the two proposals carefully then call me with your selection. <br /> I can be reached more readily by cell phone at 916-396-6319 or you can leave a <br /> message at my office 916-386-3716. 1 am also available to meet with you in person <br /> any time except Tuesday afternoon. <br /> Sincerely, <br /> George Takemori <br /> Project Manager <br /> CC: Steve Sasson <br /> End: Drawing 10657 <br />
