Metlund D’Mand hot water recirculation pump
I am thinking about installing hot water recirculation pump to reduce hot water usage. Metlund D’Mand hot water recirculation pump seems to be a good choice since it’s passive and does not use energy until you push a button when hot water is needed.
I spoke with a contractor and he is against recirculation pump since he has seen multiple cases of pipe bursts probably due to the turbulence and pressure created by the recirculation pump. I did some web search and found some horrible stories also such as http://www.amazon.com/Laing-ACT-303-BTRW-AutoCirc-Retro-Fit-Circulator/product-reviews/B001U66R7S/ref=cm_cr_pr_hist_1?ie=UTF8&showViewpoints=0&filterBy=addOneStar ,
What’s your opinion on hot water recirculation pump? We use copper pipes in CA. I don’t want to place a water bursting time bomb while trying to save some hot water.
