If a Real Estate agent leases a commercial space knowing things are wrong. Does he have to tell you?

I recently leased a space that had flooded due to a water leak in the bathroom. The Real Estate agent said he would have the drywall that was torn out from water damage, replaced. When I took control of the space and had the water turned on, water shot out everywhere from a bad valve in the bathroom that was not fixed. I also found out I share a water meter with the tenant next to me, and all of the water is heated from my water heater. The place is vacant but I have nothing in the lease that does not hold my liable for their consumption. In a nut shell this agent did not give me all the information that I feel would have been nice to have. Can I turn him in to an ethics board of some kind? I live in Texas. Any input would be much appreciated.
