Hello, At my cottage the main supply line from the pressure tank (30-50 psi range) is 1/2" pex which runs about 30 feet, no elbows etc., before it splits to hot and cold supply lines. In the current setup I am happy with the pressure at all faucets, shower etc. I am considering a renovation which would require me to change the location of the supply line (it would be about the same length/type, 30 feet and 1/2" pex) but would require 90 degree elbows, three of them. Just wondering if this will drop my pressure too much ? I can go to copper if necessary, but would prefer to use pex. Thanks in advance for the help !
