3" Water main pipe installation, update.

(NOTE: The last post dated Aug. 27, 09, on this subject had an error. The 3" schedule 80 PVC pipe, is NOT test to a pressure of 150 psi. It is tested to 90 psi.)

On the last post, it was reported, that leaks occurred at the seams when Allen tested the line to a pressure of 90 psi. (NOTE: Dunedin City water pressure is 60 psi.) The cause of the leaks turned out to be a defective batch of glue. The manufacturer delivered a new batch of glue and Allen cut out all the old seam, and re-attached the pipe using the new batch of glue. The new line was pressurized to 90 psi for three day, and there were no leaks or lost of pressure. On Friday, a Dunedin inspector checked the line and the test result and approved the line to the West Tower and Clubhouse.

Allen is filling the pipe trench now and will start on the East Tower line shortly there after. They are planning of finishing that line sometime next week. Allen will then turn off the water to all buildings for a period of 8-12 hours, while they make the final connections, switch the water flow into the new lines and test everything. Everyone will be notified as soon as possible.
