i just had a new pump installed last friday; immediately after this instillation, the water smelled like some type of chemicals, almost like paint thinner or varnish, and when I tasted it, I immediately had to spit it out. does this make sense to anyone? what could it be? It is now tuesday, and the smell is still there. If i get my water tested, what do I have it tested for, and how can this be corrected? Thanks
