I have a pipe on the outside of my home used for watering the grass. During the winter when we have a warmer than usual day, the water flows (heavily) from the pipe even when it is turned off. What is causing this and do I need a plumber?
Thanks!

During the winter what is your normal overnight temp? Does it freeze hard? Is the water flowing from the spigot or from a joint or connection?

I have a pipe on the outside of my home used for watering the grass.Tell us more. What feeds this pipe> Pump? City waster from the house? How long is this pipe? Do you have overnight freezes and warmer days? This flow. Is it under pressure? Let's have more details. Regards, Tom

Hi. The temp overnight has been around 20-25. During the day, it is around 35-38. The water is flowing from the spigot if this is the device to turn the water on/off. This is the pipe to which I connect the water hose to in the summer.
The pipebisbshort and connects to the water main and meter. The pressure is strong even in the off position.
Thanks!

Your spigot/shut off valve is defective and needs to be replaced or rebuilt. You would need to close the main valve back near your incoming water meter
