I have an older Hayward 1.5hp Superpump on my 20x40 gunite pool. It has a hairline crack underneath gasket for the strainer lid. I have epoxied it a few times, and could do so again, but thought it might be a good time to upgrade to a variable speed pump.
Visiting the pool store recently, they said the Hayward SP2600VSP would be fine for my purposes - it would be a direct hook up to the existing 1.5inch plumbing, and provides sufficient power at a price much lower than the EcoStar or Pentair pumps. The $700 price tag makes it much more doable than the >$1k pumps.
I was ready to pull the trigger, until I read the loan review on Amazon saying that while you can adjust the speeds for different durations, one of those speeds is not Zero. In other words, you can set the pump to run at x rpms for x hours, then at y rpms for y hours, but you can't adjust anything to actually turn the pump off. Reading the manual on-line, this appears to be correct.
If you can't program it to shut off, it would be running at at least the minimum rpm all the time, quickly eliminating any energy savings. I can only imagine that you can use an existing timer, like the Intermatic I currently have. But that would complete kill the power to the device when it's off, and I can't tell if that still maintains the set programming, or "resets" it, the same way I have to reset the Time and Language on my TV whenever I turn it on after a power outage. Even if it maintains the programming, it appears as if it would be awkward - if the Intermatic timer gave it power twice a day, I assume it would follow the same program. For example, if it came on for four hours in the morning, you'd have to set it to say 1 hour of full rpm, and 3 hours at low rpm, which it would repeat again in the evening. It seems it would take away some of the advantages of running high speed only in the evenings when rates are lower, etc.
Anyway, it seems as if because it's a new pump, there is very little information about it. I can't believe Hayward would put out a VS pump that can't really be programmed in the true sense, but haven't seen anything that indicates otherwise. I was hoping someone hear might have some insight or recommendations.
