Water at both showers cooler than rest of house.
We've had to adjust our hot water heater to accommodate a new dishwasher that requires hot water to be between 120-130 degrees so we've turned it down from somewhere in the HOT range on the dial to exactly at WARM.
Our main shower and our second bathtub/shower both feel barely warm but all other places in the house supply hot water. This includes the sinks in both of these bathrooms as well as the separate tub in the main shower bathroom. Our clothes washer has hot water and so on.
What could be up with our plumbing to our two showers to explain such a drop in temperature from the rest of the house?
(To be clear, the second bath/shower's water being noted is coming directly from the tub faucet, not the shower head to rule out issues with the shower heads themselves.)
Thanks!
