How do I prevent a drop in flow in a system with a pressure tank, 40/60 pressure switch, filter and water softener?
I will usually feed the home with 1" but then drop down to 3/4" and have not had problems with flow. Most of the plumbing to your sinks is 1/2" and the orifices in the faucets are much smaller so even with the kitchen sink and a bathroom or 2 having there valves open you should not see much of a change in flow at all with 3/4". The one place that will affect the pressure is hose bibs or outside faucets these have much larger passageways in the valve than sinks do. Already mentioned the flow restrictors in shower heads, these are taken out at my house before even installing them. Not long ago I found a flow restrictor in a bath faucet, don't know how filling a tub slower would save water but that came out also. With my shower head restrictions remove our guests mention how nice our pressure is. 60 should be a big improvement over 50 but look at your restrictor if you have any build up issues like lime, scale or rust the head may need a good cleaning that and removing the showerhead restrictor will probably provide the results you want.
