Review on 💧 Grundfos GRU-595916 595916: High-Performing Water Pump for Efficient Plumbing Systems by David Mcdonald

I have a messy 1885 Victorian house in New York, with long hot water pipes that require long waits for hot water, which is not good! My first plan was to install two dedicated hot water return lines that require 1/2" PEX pipes to connect the first floor kitchen and the third floor bathroom. This traditional solution means the hot water is recirculated , so there is always hot water available at the tap Great system but for me this Grundfos UP pump was a good solution as it saved me all the work associated with installing two dedicated 'loop' DHW return lines as it uses the existing cold water supply line as a "loop". " pump hot water and make it available when you turn on the faucet - BOOM! I doubted that this would actually work, but after installing the system I can report that it works very well! I've found that when you turn on the faucet the water doesn't get "quite" hot, but warm enough to wash your hands, and most importantly don't wait for cold water to get warm and/or hot. After about ten seconds the water is visibly hot, definitely hot enough to wash dishes or do what you normally do with hot water! Pump comes from your water heater, making it easier in the future when you need to replace or repair the pump. Simply use the comfort valve part installed under your sink. The stainless steel* hoses (pump set includes 2) have rubber cone washers so you only have to tighten them on the valve without using pipe grease or teflon tape on the threads. long these valves last in daily use i will let you know if there is any problem. All in all a good product and innovative technology for saving energy and water!
