According to our calcs based on hwsfu of 30 at water heater and given 80psi and 100' max dev length we should have a 1" main hot water trunk. The 80 gal tank we have has 3/4" connectors on it (or at least the flex lines are 3/4"). Can these be changed to 1" or can we get a tank with 1" connectors? If not do the 3/4" connectors not create a bottleneck and/or make the 1" trunk ineffective?
The 1" trunk would be very short around 10' run connecting to two 3/4" branches on one end and a third 3/4" branch on the other end.
