When we went to Oconee, I had very little water in the fresh tank. I turned the pump on at some point when we weren't connected to city water and it didn't build pressure, but I assumed there was not enough water.
Right before we left for greenwood, Michael called me and said they were having water issues at the park and I should fill my tank. The issues were fixed and we didn't need it, but after we had unhooked from water this morning and turned the pump on and it didn't build pressure.
When we got back I pulled the access panel and found extremely clogged screen and the filter housing cracked. I guess winter got it. I don't use antifreeze on the water supply, only drains. I blow the inlet lines out but there must have still been water in the filter.
