    Valve handle broke. How can I tell if it's open?

    No - the clips on the inside of the handle broke off and it's not clear where they were attached. The handle just spins freely. I think I'll just go turn the valve manually and have my wife feel for the pressure coming from the outlet until it feels "strongest" Thanks all

    Valve handle broke. How can I tell if it's open?

    Well, found out that it's a Super-Pro 2" valve, but still no luck determining if it's open. Ordered a new one that will arrive next week, though.

    I don't, unfortunately. The handle says <SP> in a diamond and 2" under that. It looks a lot like this...

    Valve handle broke. How can I tell if it's open?

    Handle broke and I didn't think to consider where it was before I pulled it off. I'd like to make sure it's full open until I can get a replacement. Is there any way to tell from the following pic?

    Pentair MasterTemp 400 starts cycling when water is 88 degrees

    I don't see a sticker/barcode anywhere, but the circuit board is 42002-0007 REV A. The pool came with the house, so I don't know much about the history of it. In any case, I have a thermal regulator showing up next week and I just won't run the heater until then.

    Pentair MasterTemp 400 starts cycling when water is 88 degrees

    None of the buttons on the heater do anything. The heater seems to only be controllable via the EasyTouch. Here's what happens: The heater is normally without power. The screen is blank. When I turn on the spa heater or the pool heater from the EasyTouch, it supplies power to the heater and...

    Pentair MasterTemp 400 starts cycling when water is 88 degrees

    I wasnt able to get the heater to show the exhaust temperature. I turned it on from the easy touch, waited for the blower, then waited for ignition and held down the spa heat button on the heater for 10 seconds. It just continued showing the water temp.

    Thanks everyone. I removed the thermal regulator and the heater doesn't cycle anymore. Ordered a new one and will replace it. The bypass valve seems to be in good shape. It was closed when I felt up there, but it's intact. Thanks!

    Thanks! I'm going to pull the thermal regulator and test it in hot water. The filter gets cleaned quarterly.

    Pentair MasterTemp 400 starts cycling when water is 88 degrees

    Hi - I have a MasterTemp 400. When I turn on the Spa, the heater runs constantly (maybe 10 minutes) until the water temp is about 88 degrees. Then I get an HLS led and the heater starts cycling. Off for about a minute, then on for about 2 minutes. The water eventually gets to 104, but it...
