    Pump damage protection: universal flow switch / shutoff timer?

    Is there a generic assembled, ready-to-use flow switch / timer available that can be used to protect a pool pump from loss of intake? This would connect between main power and the pump, and with power applied would immediately start the pump as usual. If no output flow is detected from the...

    A long-life, low-maintenance ozonator?

    The DEL 301 in our big 8x8ft hot tub just died. Non-repairable unit, apparently the UV lamp shattered, blew a fuse in the spa pack, need to replace the whole ozonator. I'm looking around for relatively low maintenance replacement, but it looks like ozonators are just all-around high...

    UltraPure Ozonator

    Although I do not have this device, it's basically a standard fluorescent lamp. As such you can probably consult standard fluorescent wiring diagrams for how it is connected, and don't really need anything specific from the ozonator manufacturer. Someone mentioned a starter and ballast, so that...

    Intex salt-water generator: J9 / MOTO board connector?

    Are there any truss-reinforced spa covers?

    It seems a common death of spa covers is that eventually the thing loses strength in its spine along the hinge, and starts drooping until it collapses into the tub. Time for a new cover. Though it doesn't sound like a hard problem to solve.. just build a triangle truss structure inside each...

    Looking for fully automatic water testing and auto chemical dosing

    Okay, well, this didn't seem like a ridiculously expensive request to begin with. This would be for a residential pool and a hot tub. Reading these instructions, this looks like this may take 15-30 minutes to do. And this needs to be done daily...

    Looking for fully automatic water testing and auto chemical dosing

    Can anyone recommend fully automated test systems, which can sample the water and test it on a daily or hourly basis, and which can also continuously inject dilute amounts of corrective chemicals as needed to maintain a trouble free pool? I am looking for a solution that has little more...
