PEX fittings go INSIDE the pipe. They are therefore smaller in diameter)
A 3/4 PEX fitting is equaly wide as a 1/2 copper fitting - this reduces the water flow.
Does that mean that when I replace 1/2 in copper (example for a shower) I should use 3/4 PEX?
(On the other hand PEX uses almost no elbows and no 90 degree turns etc. - this factor increases the water flow)-
(P.S. NYC has ridiculous rule not allowing any PEX to be used in fresh water (officially because of rats but that is false since (I think) it is allowed in radiant pipes which are also prone to rats -) This is probably because of plumbers union (who want to rob consumers by forcing the use of copper which is 10x more work and needs special skills). Because of all these crazy rules - it cost a few hundred dollars for a tiny plumbing job . Any comment on this?
