Hey guys, this is a long shot, but I wanted to see if anyone has had this issue or has a solution other than buying a new head. I bought a GW 222 a couple of months ago and it has a portable head in it, that is also plumber to a macerator. I filled the freshwater reservoir today, but it is leaking from where the clamp is that connects the upper to the lower reservoir(better than leaking from the wastewater side). Is there any repair for this or is it likely a crack in the tank? Thanks guys
