(Hopefully) minor warranty issue with new construction - Delta Build

[Brett D.]

After three years, Delta Build finally completed my Cape Coral rental.  Tenants were placed two weeks ago.  They immediately contacted management to let them know one of the tubs doesn't drain and the water gets warm but not hot.  Management went back and forth with Delta until finally getting an email from Delta that these issues weren't covered by their builder's warranty.

1. If the water heater gets the water warm but not hot, I can't imagine it's anything other than the dial needing to be turned up.  My manager will go out there and handle that.  Hopefully it's nothing else.

2. Most likely, some construction debris wound up in the drain.  We're going to have a plumber vacuum the cleanout for the whole house to be sure there's nothing else.

3. Shouldn't this be part of a builder's new construction warranty?  Any recourse?

Thank you,

Brett
