    Priming a Pentair SuperFlo Variable Speed Pump

    I'm pretty sure that when pump instructions say to fill it with water, they just mean up to the bottom of the inlet, which you should only need to do when first installing or perhaps if the pump ran dry due to a low pool level, not when just opening the lid to clean the basket. They really...

    Account doesn't stay logged in

    That did seem to help -- I cleared cookies and as much of the locator-bar history as I could, then manually typed https:// and logged in (and to get to the subscribed threads page that I usually go to), seems to be sticking now. Thanks! This has been bugging me for almost a year :-)

    Account doesn't stay logged in

    Anyone else having this issue? Every time I come back to troublefreepool.com after an hour or so, I have to log in fresh with username/password. Yes, I'm checking the "stay logged in" box, have checked cookie settings and cleared cookies. I've tried several different browsers, all with the...

    Wireless Thermometer

    From some quick searching, it looks like there's also a WS-314 model that doesn't have the display on the floating unit or the solar cell, only $1 cheaper but my unit display doesn't work anyway and batteries seem to need changing more often than the quoted 1-2 years even with the solar cell...

    Wireless Thermometer

    I too had bad luck with the Acu-Rite ones from Home Depot (never lasted more than 4-5 months). I also have the Ambient Weather WS-14; it's been in the pool for 2.5 years now through the 105+ degree summer days (with water in the mid 90s) to the below-freezing winter nights (with water in the ow...

    Intermatic T104

    Is this panel on an outbuilding, not physically connected to the main house? If so, and if it was installed longer than I think 10 years ago, the 3-wire feed and bonded neutral/ground would have been code compliant at the time and still legal. If more recent, current code would have 4 big...

    Intermatic T104

    Ahah -- I missed a big clue you posted before: "R to R cant get a measurement". That means both hot legs are connected to the same leg of the house power and don't have 240V between them. Basically, for most houses the transformer at the street drops the voltage to 240V with a center tap --...

    Intermatic T104

    Switched in this case means controlled by the T104. If it were a 240V pump wired in accordance with the wiring diagram that came with the timer, both wires (which are both considered "hot") going from the timer to the pump would be disconnected when the timer is off. In your case, only one...

    Ideal FC for a NON closed pool in winter

    There's a general accepted thought that algae won't grow in water colder than 60 degrees F, which yours probably is. However, I find it easy to maintain a normal chlorine level all winter because the cool water and low sun make last a lot longer (weeks between adding instead of days), so it's...

    Intermatic T104

    1) I agree with JamesW that the pump is likely set to 120V. For a paranoia check, measure the voltage right on those wires right at the pump. If it is indeed 120V, you should be able to wire the new timer exactly the same way as the old. 2) This doesn't appear to apply to the OP, but agree...

    Intermatic T104

    Is there any chance your pump runs on 120V? The silver wire might be a neutral, with the 2 red hot wires (240V across them) running the clock motor on the line side, and the unswitched neutral and one of the switched load outputs (120V between those) running the pump. I'd check the pump's...

    Testing chlorine 4 tests 4 different results

    Those results are within +/- 5% of the average; could easily be just a slight difference in water in the cylinder (0.5ml difference would do it) or in your perception of "clear". For this purpose that's plenty accurate; I wouldn't worry about it. You could use a larger 25ml sample (divide the...

    Chelated Copper vs PolyQuat for cold Wisconsin Winter Closing

    What's your current water temperature? I don't close my pool here, so take this with a grain of salt, but the recommendation here is whenever possible, delay closing until the water temperature is below 60 degrees F, and open it again before the water gets above 60. Algae does not grow much if...

    Making your skimmer work better...

    I have a 1960s era pool with a single skimmer that's quite wide (12-13" opening; makes it impossible to find a replacement basket and hard to find weir doors). Worse, there's just a single return on the other side of the same wall that's just a 1/2" pipe hole, so I can't even put an eyeball on...

    Pool light transformer makes a loud thump noise when turned on

    I would take the bulb out and check that you have 12V right in the bulb socket -- and do you get the thuds and hums when there's no bulb? Caution that many bulbs say not to use them even briefly outside of the water, so if the test above passes I'd put the bulb in, seal it up and put it in the...
