    Mastertemp 400K BTU HD - Making a vibration or metal rubbing noise?

    I did reach out to my PB already with the same clip, but I figured I would ask on here as well. I noticed a metal vibrating sound or metal rubbing sound making some sort of high pitch noise when my heater is running. It is less than a year old, not sure if there is anything wrong with it or...

    Pentair Mastertemp HD 400K slow heating or too high of expectation?

    Yeah, I'm pretty sure I measured it right. I thought I bought a 10x10 solar cover but I bought a 8x8 on accident. I tossed it on anyways and heated up the spa. Based on my time starting at 57 degrees, it took roughly 1.5hrs to get to 102 degrees. Seems like similar performance with or...

    Pentair Mastertemp HD 400K slow heating or too high of expectation?

    I have noticed that the time it takes to heat this spa at my new house is significantly longer than the amount it took to heat my spa at my old house. I know this spa is a little bit larger but not overly larger. Currently, I have the spa at 3275 RPM and a Mastertemp HD 400K BTU heater. I...
