I turned the shower in the head on for the first time this season and water was spraying at the fitting under the tap where the shower hose attaches. I figured I had a Crack so removed the tap completely and brought home. I took that little fitting off and the PO had sealant on the to of it. I remove the sealant to discover a small hole which looks factory. I can't understand why it would be there. Any thoughts. I plan on re-sealing it.
