So long story short, we’ve had contractors working on our house since last August who are slower than molasses and have been without a functioning kitchen since about January. Due to that and just needing a functioning sink I put in the above plumbing since the contractors refused to do it for various reasons that I won’t get into. We just want to be able to wash dishes and potentially cook since we haven’t been able to for months. I’d love to know if I can fix this. Thanks in advance!
