    Earlier today my neighbor brought it to my attention that there was a heavy flow of water coming out of a drain on the side of my house. After turning of the main flow of water into my house(located in the garage above to water heater), the flow outside stopped. I turned the water back on from the street to verify that all sinks in the house worked and they did but I had to turn the water back off coming into the house because it was literally flooding my neighbor's yard. These drains are on the outside of my house about a foot up from the ground coming through the wall and siding. I'm not sure what these drains are for but think one is coming from the water heater in the garage and the other possibly a run-off for the air conditioner unit. Any help or advice is appreciated.

    I actually did toggle the relief valve and noticed that there was a little run-off of water out of the other pipe outside the garage but not the same pipe that had the water pouring from it, plus the amount that came out was only a small trickle. I'm sorry but I don't know much about the significance of these pipes and cannot find much about them on the internet.

    In England we have pipes like that which serve as an overflow for toilets and water tanks that use fill valves to fill them up. When the fill valves go bad these can overflow through pipes like the ones you mention.

    I have never seen them in the US but who knows?

    Perhaps one of your toilet tanks is overfilling and overflowing? Trace that other pipe.
