Attached is a simplified drawing of how the water is supplied to the two ends of my house. Heavy black line is supply (PVC) from the meter. That ties into two 1/2" copper pipes (represented by the green line). One 1/2" copper supplies cold water to the east end of the house. The second 1/2" copper pipe travels over 100' around to the back of the laundry room. From there it ties into a 3/4" copper pipe (represented by the blue line). That 3/4" copper supplies cold water to the two bathrooms a the west end of the house and to the hot water heater. The hot water supply is a 3/4" copper loop (red line) (which has a recirculating pump on a timer).
The water pressure in the two west bedrooms is adequate for one shower, but less than adequate if a second fixture (shower, sink, toilet) is running on the west side.
I'm thinking that having 100+' of 1/2" copper in front of the 3/4" copper supply to the west bedrooms is robbing me of a lot of pressure. Is that correct? I'm thinking that if I abandon that long length of 1/2" copper and replace with 3/4" or larger PVC from the main supply line, I'll markedly increase the water pressure in the west bathrooms. Is that correct?
