I received a free hot tub. It was hard wired to the former house. I want to test it to insure it runs before putting in the time and effort of wiring to my house.
I have a four wire 230v extension cord to attach but there are 5 wires. I’m unsure if it is safe just to test it. I’ve identified the ground, neutral, and the two hot lines. The other two lines are unknown. A picture below will help explain it. This is a Caldera Utopia Tahitian.
Hello all. I'm looking to stop being lazy and hopefully get to the bottom of my issue. I should mention I am a noob so go easy on me. About 2 months back I had my pool guy apply a cleaner in the pool (at his suggestion) that helped remove some of the darker spots on the floor of the diamondbrite. It worked pretty well however two spots got much worse in the process (see below). I'm trying to understand what this is and how I might clean it. Or what other recommendations you guys might have.
Also on somewhat related note, I've been trying to clean the tiles behind a waterfall feature I have. It has a white haze and one spot also have a build up of material (Im thinking calcium maybe?). Anyways Ive tried a pumice stone and CLR but no go. Any tips on how to best take care of it? When the waterfall is on its hard to see but not so nice looking when its off.
Thanks all!!!

This project has been going on for too long now. This week we installed 6 X 3 = 18 aluminum boxes on the roof each of which holds maybe 15 ft of coiled 1/2" copper tubing painted black. The boxes sit on the flat roof. The cold water line has an air escape valve and the 'hot' water line has 2.
At ground level the cold water line happens to have a flexible joint at the moment. When I turn the pump on the flexible joint flexes (as in bubbles) and there is pressure to the roof because if I remove the cold water valve water spouts but no water seems to be returning hot from the boxes. The input water is piling up.
If the spa is empty and I pull water from the pool to the roof and attempt to fill the spa, it takes about 4 hours. The other thing is there are always air bubbles going into the spa, At first I thought - ok a new system maybe it takes some time to force the air out... but after hours that doesn;t seem right,
I thought maybe I need to incline the panels some to let the possible air in the system elevate to the valves.
I thought maybe - and it would be a TON of work - to maybe send the cold water through 6 rows of 3 boxes rather than 3 rows of 6.
The PVC to the roof is 1 1/2". All the copper tubing is 1/2"
Any ideas greatly appreciated.
