Thanks everyone! Gonna see how I can afford to do this. There is a $2 difference between GMPartsHouse (or whatever the place is called) and Amazon, probably sold by the same vendor.
Had a funny "pool hole in my back yard" moment. The city inspector came to certify the install. She had to "red tag" it because the plumbing has not been pressure tested, the auto-level system has not been installed, and the spa plumbing is incomplete. When she told us she could not certify the install, I said the builder was not expecting her here until next week. Then the construction manager drove up here to read what the tag said.
He claims there will be a crew here on Saturday to finish what need to be completed so the inspector can return on Tuesday. We'll see about that.
