Thanks, I'll give it a shot.

It took them a while but yes, they did respond. The response was pretty useless. Here's what I got: Original question from me was can you provide a water pressure drop curve for the ETi 400 High Efficiency Pool Heater? Hello, thank you for contacting Pentair, we are sorry for this delay. At...

Yep, that appears to be it. Too bad they no longer remain in production.

Yeah, I know. I looked there first and thought maybe some other mfg might have such an item. I have an application that could benefit from such a valve.

Have any of you seen a Y valve like the one shown in the Pentair Intellivalve manual like this? If so, can you provide a mfg and/or p/n?

Thanks, I've sent them the question. If I get a response I'll post here in case anyone else needs the info.
