Due to the chitty piping in our house (5 pipe leaks in 10 years) we are having our house e-piped monday. what they do is inject an epoxy resin into the existing copper pipes to coat the insides to stop any current leaks and in theory prevent future leaks. Its done in many industrial applications and apartment complexes frequently it cures, and good to go. its like installing a liner in existing pipework and is less invasive than an entire repipe job, and has a 10+ year warranty. making water for the 2 to 4 days wont have any water, but should I have any concerns after? have a 7 stage ro/di unit with spectrapure membrane and name brand filters and 0.5 micron carbon and chloramine blocks b4 3 stage di resin.
