Hi all,
I have a recirculation loop in my new home. It is approx 250' start to finish--one long loop with t's off for the fixtures. Instant hot water when you turn it on. However, I'm having an issue when I turn on a faucet/shower nearby. The original faucet that was turned on is hot, and the next one is luke warm or even chilly. When I shut them both off and then turn the second one on, it's hot...here is a picture. Please let me know what you think
