For the last 5 years I've wondered what this big (6inch) PVC pipe was on the side of my (Tampa, Florida) house. I've wondered, but since I belong to the "Leave Well Enough Alone Club", I've never investigated. Then today I uncover the same size pipe under my pool deck bar (hidden under a base cabinet). It is filled with water and it is about 6ft from the other pipe on the outside of the wall. Anybody have any thoughts?
