: 1-800-356-3496 And it is not PVX,it is PB tubing. Beses the gray tubing in the house, you probably also have the blue pipe from the meter to the house. It is the same material and just as bad. Keep the repair bills for the leaks you have already fixed, and submit them with the claim for the repiping.: : I presently have gray PVX piping in my home and was told by a repair man that this pipe should be replaced.
