Im surprised the plumber cant explain it. Im neither a plumber or a water expert, but know that new copper pipe use to carry water is renowned for imparting a metallic taste to your water supply. It can also give your water a nice blue/green tinge and if the pipes have been soldered, excess flux may also taint the water.Originally Posted by 3D2A39395F0 link=1323467658/0#0 date=1323467658
If my supposition above is correct, while thats not good news, it should go away in time. Speaking to Bombora might still be a good idea.
