I'll cut right to it. My wife and I bought a house in December. It came with a "non-functioning" hot tub which the PO had installed into concrete.
The house has a pool which is what we were really after but I thought it would be icing on the cake if I could revive the spa before Fall/Winter.
I've attached some pics. It's a Cal Spa and it looks to be in pretty good shape. But I can't tell if everything is hooked up correctly. There are a couple of pipes that don't connect to anything. I'm assuming it's similar to our pool and one of them is possibly Waste. Anyway, it was 3/4 full when I pulled off the top so it appears to be holding water. The water was clear but soot and a family of dead lizards had settled at the bottom. Got it drained for the most part. And now I'm wondering what the smartest and safest approach is to troubleshooting the equipment.
NOTE: There is literally zero-access to the exterior of the tub. It is surrounded by concrete. On one side is a 4ft drop off leading to the swimming pool below. The pumping/heating station is on the opposite side under our deck and if I had to guess it hasn't been ran in 1-2 years. Unfortunately we didn't get any details from the PO. For all I know the PO called it broken because it doesn't heat the water. Or for all I know, there are cracked/leaking lines around the tub that I can't get to without busting up concrete slab.
Anyways, sorry for the long post. I was just hoping to get some guidance or "whatever you do don't...." comments from the Spa forum. Thanks guys, enjoy the pics
