Hi, folks. Pool just finished and filled 3 wks ago. Soon after noticed dark spot on back side. Believe it is damp but hard to tell. Expands and contracts from day to day - not sure why. Waiting to hear from PB. Any ideas? Very close to skimmer, about 18 inches to the right. Thx

It is a valid concern and should be repaired by your builder...if in the spa side, it could be the plumbing, rather than a leak in the shell.... now if we only had another picture zoomed out so we could see where it is on the pool... Raised Spa?... Raised Bond Beam?... The world may never know.... ;)
