Does anyone know/or have a small drain on the outside wall of their house? It is on the outside building wall in the same area as the inside shut-off valve which is for the house water. It is dripping. Sorry it sounds confusing, but difficult to describe.

I have a small drain on the outside of house in the same area as the outside faucet and also in the same area of the interior shut off valve for home water. Does anyone know it's function and why it would be dripping?

It is the drain for the house air conditioner.

As your air conditioner cools the air going through the unit, there is some condensation. That water falls into a drip pan under the unit. The drip pan has a drain pipe leading to the outside so the pan doesn't overflow. You are seeing the drain pipe.

We have a pipe that exits off a pressure valve before the hot water tank that drips outside. I notice all the neighbors also drip. These are CY villas from the 2006 era.

Yes, pressure relief valve drain. If dripping, the seat is not sealing.

I think you may be mistaken. We also have a CYV built 12/05 with a similar drain outside next to the garage door. It is attached to a pressure relief valve on the cold water inlet side of the hot water tank and usually emited a small amount of water when we showered. Because it was in the driveway it was a less than perfect arrangement. When we replaced our hot water tank the plumber replaced this pressure relief system with an expansion tank that sits above the hot water heater. This pressure relief valve should not be confused with the one that screws into the side of the hot water tank. Unfortunately there’s really no way to remove this outside drain from the CYV unless you’re also prepared to replace the vinyl siding.

IF you want to know anything about your home in The Villages, call Warranty. They are amazing and patient and nice, if you are amazing and patient and nice.

It's from your air conditioner. As it runs the A/C pulls water out of the air which eventually makes its way done that tube to the outside and drips.

Thank you everyone for your help and advice!

Redcart most likely hit the nail on the head. Can't be sure because there is simply not enough info given to say for sure....a picture would have helped.

A typical home would have everything others have mentioned. In addition, it could also have been a backwash drain for a water softener.

A normal home could easily have 4 or more drains like are described....A/C drain, water tank t&p valve, pressure valve off the cold water in older homes, softener drain, even a pool auto-fill overflow drain.

The A/C drain should drip whenever it is on. The softener could drip when it regenerates. All others should not typically drip. If they do, repairs are needed.

Obvious question would be - what's on the other side of the wall? But I agree that's what it looks like to me also.... that being said, I have two near each other. One is for the T&P - the other is a drain line for the pan the hot water heater sits in.
