Stray Coupler in PEX Water PipeFrom: aasebedo@amsac.net

CommentsMy new home is plumbed with PEX-type water-supply pipe. I was recently in the attic, trying to track down the pipe that was banging against the ceiling whenever bathroom water fixtures were turned off ("water hammer"). At the time, I noticed that the plumber had installed a "T" coupler at one point in the supply line, but instead of using the coupler to send water to another fixture, he just capped the coupler. When asked about it, the plumber said he must have run out of straight connectors, so he used the "T" connector. In connection with the "water hammer" problem, I read on your web-site that so-called "air risers" are generally not to be installed, since water will eventually move into the "air riser" and can become stagnant. I don't think the plumber was trying to install a sort of "air riser" with his coupler (the "riser" formed by the capped coupler is only a couple of inches high), but I am not sure whether I should be concerned that it will trap water that might become stagnant and therefore a health hazard. The plumber, not wanting to go into the attic during these hot summer days, tells me not to worry. Should I? Thank you for your assistance.
