Your pic is of the water heater bypass valves setup.
As pictured, the valves are set to send water through the heater.
These are not drain valves and would not be the cause of water overflowing.
Turning all 3 valves 90 degrees clockwise will set the water flow path to "bypass" the water heater tank. Water incoming from lower left then vertical thru the "bypass" valve and on to sink/shower/lav.
Thereby not passing thru the heater tank.
As shown, the water path is from incoming (lower left white PVC pipe) thru bottom valve into blue (PEX ) pipe on into heater tank then out (heated(presumably)) via red and on to sink/shower/lav.
IF the heater tank has an open drain valve on it, these valves, as currently pictured, will be sending water to the heater tank and then be drained thru that; which might be the drainage you are experiencing.
