Can you elaborate on this please?
It takes 90 seconds for hot water to flow from my water heater to my kitchen in the winter. I’m not sure if I have 1/2 or 3/8 pex (I’d have to crawl under the house to check). I’ve been thinking of adding a small Bosch water heater under the sink or a recirculation like, but maybe I should reduce the size of the pipe too
- bombcar 3y agoCode will have requirements like "pipe must flow X gallons/min" or something - and then a table of pipes of various materials and if they meet the requirements at a given length. But they don't list all possible pipes, or all lengths. And the argument is that 3/8 PEX will flow to requirements and have a smaller amount of water sitting in it.
