I hope all that think the tape being used on gas piping is irrelevant, please read on. I am an New Jersey Lic Master Plumber. I am an authorized service agent for a major plumbing fixture manufacturer out of Wisconsin. A urinal flushometer pre-installed on the urinal was installed in a residence not yet occupied. The urinal flushometer started dripping as soon as water pressure was applied to put the unit in service. Passing by before having the replacement parts I decided to stop in since the home was open still under construction in the finish phase. I disassembled the components and found that a strand of teflon type white tape had followed the water flow thru the valve and remained across the seat and caused the water to drip past the spring loaded diaphragm that would normally stop street water pressure. The pilot light on a gas regulator closes against a 1/4 pound of pressure. Tape shreds will stop the diaphragm from fully closing creating an explosive atmosphere. NOT WORTH USING TAPE ON GAS PIPING.
