I needed to do some things around the house today.
I noticed that the spa cover lid removal mechanism was messed up. When taking the system off, I found that the bracket by the wall was severely rusted. So, I sanded off the rust and painted with Rust-Oleum.
In order to put the cover mechanism back on, I had to drill new holes on for the from latch. It went back on ok.
I also drained the spa and put in new water.
