Hello again. Another question. I also get a lot of diverter valve noise with my pump 1 diverter on my Caldera Hawaiian. Had the dealer out to look at it and his comment was. Hummm, first I've heard of this... Caldera also claimed ignorance. The diverter valve for pump 2 is not noisy, but it sure is for pump 1. Should I ask the dealer to change the pump out? Pump 2 also has a problem with shutting down. Once, it lasted 45 minutes and shut itself off and would not come back on until several hours later. It's been okay since then, but last night it shut itself down again after about 1 1/2 hours. Normal? Appreciate your feedback...
