Had a 20' round AG pool installed last June and pressure guage on filter had condensation in it (and never worked). Asked the people at the pool store about it and they said I "didn't really need the gage".

While the filter was stored over the winter the gage developed corrosion so I brought it to the pool store and they replaced it (about two weeks ago). They also said they didn't have to replace it, but they did.

Now the new gauge has condensation and corrosion in it, in just the past two weeks. (Plus the filter is leaking a bit around the gauge). Has anyone had this problem?
