So the tank is grounded.
does a water heater require a ground wire?
Any ground wire has to be connected to an independent ground wire that returns directly to the distribution panel and not to the neutral of the circuit.
Some faucets have hot water because they are connected to a water heater that can provide hot water on demand. Other faucets may not have hot water because they are connected to a different water source or do not have a water heater attached to them.
To turn off the cold water supply to the water heater, locate the shut-off valve on the cold water pipe connected to the water heater. Turn the valve clockwise to close it and stop the flow of cold water to the heater.

When connecting the red wire to the white wire in a water heater wiring setup, ensure that the red wire is securely connected to the terminal marked for the white wire. It is important to follow the manufacturer's instructions and consult a professional if unsure.
To properly ground a water heater, follow these steps: Turn off the power supply to the water heater. Locate the grounding screw or terminal on the water heater. Connect a copper grounding wire to the grounding screw or terminal. Securely attach the other end of the grounding wire to a grounding rod or the main electrical panel. Turn the power supply back on and test the water heater to ensure it is functioning properly. Grounding helps prevent electrical shocks and ensures the safe operation of the water heater.
You do not have to turn the heater on until you are ready to heat the water, some installers put a tee or bypass before the heater so the water does not go thru the heater many do not since the heater is on the clean side of the filter, some people just want a bypass valve their in case the heater fails they can keep the water flowing around the heater, Take the cover off, start the filter up, start vacuumimg, when ready add your chemicals. continue running the filter get your water tested, when you feel you are about ready too swim turn the heater on too warm the water if you desire to.
