    Zodiac MX8 Hose Weights

    I was shopping for new hoses for my MX8, and I saw lots of posts for weights. Any experience with these? I'm not as much interested in the claims that they improve robot navigation (though that would be nice), as I am with having the hose not floating on the surface, where it tends to block the...

    Aqualink-compatible VS pumps - alternative to 011056?

    I did a whole lot of research and was going up upgrade my Aqualink to a iAqualink v3, and get a 011056 Pentair VSF pump which is apparently compatible with it. But, my installer has told me that his supplier says that Pentair's factory is shut down and that they can't get the 011056 or other...

    Replacing Pump with Pentair Intelliflow

    I'm tired of the drama with my current 2HP Super II pump. Having the case leaking issue that doesn't seem to be fixed with seal replacement. * I have a heat pump, rooftop solar, and a suction-side cleaner, so the pool (<10k gal) still has a pretty big pump. I'm assuming the current pump was...

    Cost of Automation - Why?

    I am an engineer, and looking at the Jandy automation systems, I can tell you that this is 1970s/1980s technology. Newer boards add processors, but the requirements are minimal. I can understand why a control board would cost >$500 in the 1980s, but nowadays this tech should probably cost $100...

    Economics of Two-Speed Pump Operation

    Upgrading to a two-speed pump. Have heard it will be a big energy savings, but not clear as to how this works, how I should configure it. My system is set up as such: I currently run 6 hours on pool, then 2 hours on spa (allows solar heater to get spa hot-ish, in case I want to use it). It...

    2.5HP UST1252 pump - repair, replace, or upgrade?

    I have a 2.5hp pump that *seems* to be turning, but sounds weird, and almost immediately trips the breaker. Noticed a burning smell the first time it happened. I think it might be toast, though it's odd that I saw it moving still when I tried starting up with the skimmer lid open. Any...

    Jandy Aqualink to control heat pump

    I am trying to figure out where to locate the control wire that I am supposed to use to have my Aqualink control panel control my new heat pump. It sounds like the correct wireset is "Pool Low Voltage Heater" on the green terminal bar, but I am not seeing any voltage (AC or DC) appearing across...

    Solar Heater Overheating Pool with Jandy Controller

    My rooftop solar heater tubes keep overheating my water. The temperature is set to pool 86, spa 100, but the solar never turns off - once the spa reached 117, and the pool today was 96. Is the controller (which is controlling the solar heater via an actuator) supposed to be smarter than this...
