Hi, Jimmy - This is exceedingly unusual. Even more so in that you had several instances where our fittings would not hold pressure. In those rare occasions where leaks have occurred, it's usually because 1) the fitting was not clean. Sand, plastic saw dust from cutting the pipe with a saw, or any other kind of grit is detrimental to the sealing of the product; 2) stiffeners were not used; 3) there is a scratch or gouge in the PE pipe going into the fitting; 4) pipe going in or out of the fitting is stressed by being installed on a radius; 5) the pipe and the fittings are a different dimension ratio (SDR or DR). We're curious to hear details of your installation. If you're willing, please contact Dave (x1026) or Jon (x1010) at (661) 257-3923 M-F 8a-5p. Thanks.
