I have an underground cistern which was professionally installed. It is only used for irrigation. I noticed the pressure relief valve was installed outside about 3 feet from the tank. The tank is inside the garage. There are no valves, obstructions etc. I assume it was placed outside in case it opened. It is not used in freezing weather( Atlanta). The pictures I have seen show the relief valve adjacent to the tank. Is the present installation ok?
Thanks in advance.
