My Bypass is at the inlet. Water line in, then splits to two. I missed it a few times because it's against the steel brace. I thought it was routed through the brace, but when I put my finger around it, I felt the lever underneath. The valve looks like it goes through the brace, but it's actually tight against it.
Note; With the valve on I get hot water. With the valve bypassed, I still get water flow from the hot tap, but it's not heated.
