Ok, valves are fully open.
The new delta flow is 2 cups to 2.2 cups in 10 seconds. The old deltas in back measure 4.4 to 4.6 cups in 10 seconds. So stands to reason it will take twice as long to get hot water due to reduced flow. Unless I find easy way to open up flow I’ll just live with it no sense fixing something that’s not broke… I’ve looks at other brands most flow 1.2 to 1.5 GPM. One brand flowed 2.2 GPM some didn’t’ list flow spec’s.
