If I could give zero stars on would. My contractor finished our job two weeks ago. I started noticing the pipes rattling. I called the contractor and he opened up joining wall between my bedroom and the newly remodeled bathroom. Turns out this cobbe  valve is garbage. Not only do I have to buy a whole new shower value/system, but there may be potential  need to replace tiles again.  I have to pay for all the labor costs and new materials because this is not the contractors fault. It’s Cobbe’s.
