These under sink recirculation valves that have been gaining in popularity over the past years are great for residential use.
Watts calls there valve the "Premier". Grundfos has one called the "Comfort valve". Other manufacturers I am sure are out there.
My questions: What's the difference between these two valves? And for that matter, what's the difference between any of these valves that are made to do the same thing?
I have had many opinions expressed toward me saying that one is better than the other. Also have gotten the speech that if you use one with a pump that is not watts or grundfos, (interchanging the valves) that the warranty can be void??
I can't identify any differences in the valves.
Has anyone out there experienced this? and if so, how did you resolve the issue?
Thank you ahead of time for your input.
