On Friday evening while we were enjoying the spa the blower motor died. This is the second occurrence of the motor dying. It's death, is unfortunately, rather predictable. We use the spa and the blower for less than 30 minutes (as required by the vendor) so that the blower can cool down. In both cases the blower died after five uses of the spa. The pool builder replaced the blower the first time saying it was defective, I'm having serious doubts about that now.
Here's what I know, if you need more information please ask.
I downloaded the manual for the blower and the instructions say for a run over 25' to have a Hartford loop and a check valve. The pool builder did neither. In order to get to the pipes, they will either have to dig under the concrete slab (while the slab is fiber reinforced I cannot imagine that digging under it will help the structural integrity) or they will have to cut through the concrete slab (which defeats the purpose of using the fiber in the first place to ensure one continuous and strong slab). If they dig under the concrete, I'm guessing they could use piers or something to keep the integrity, not sure. Also, they would have to run an additional 24 ft of pipe to extend the pipe to a place where we can put the Hartford loop and the check valve.
I am losing serious sleep over this. So I ask the following:
Thanks in advance for any suggestions.
Here's what I know, if you need more information please ask.
- Blower is over 85' from the pool
- Estimate 5 X 90 degree bends (sweep 90)
- Estimage 2 X 45 degree bends
- No check valves between the blower and the spa
- 2" pipe
- Depth of jets is 11"
- No Hartford loop
- Polaris 2 HP blower
- 6 WaterWay jets in the spa
- pipes around spa are under fiber reinforced concrete and travertine

I am losing serious sleep over this. So I ask the following:
- Is there a blower besides the polaris that can handle a long pipe with water in it? I saw that the waterway Santana II may have better heat dissipation.
- Any alternatives besides going under the concrete or cutting through the concrete?
Thanks in advance for any suggestions.
