Pressure Relief Valve

[Sbudnick]

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.

It's outside so if it begins to relieve pressure your garage doesn't get wet.

Outside is fine as long as it isn't a freezing climate.

I'm in a freezing climate so i cant put them outside. On smaller systems I just have them at the tank. On larger systems the valve is at the tank but I'll route a discharge pipe outside.

I've got a few jobs with the PVR in the pitless. No mess in the house....

For me to meet plumbing code requirements, I have to plumb a pressure relief valve either to a floor drain or the discharge to outdoors, with an insect proof screen on the end of the discharge pipe.

I like to be able to see the discharge of the pressure relief and that is a high pressure alarm. If it is plumbed to a drain or at the pitless, it can pop off and no one will know it.
