Upgrade water line from 1/2 to 3/4?


Hello pros


Wanted some feedback and thoughts on upgrading to 3/4 water line. Here is the scenario.


The main water line coming into the house is 3/4. After the inside house meter it goes about 10 feet at 3/4 and then splits into a T fitting and goes from 3/4 to 1/2 and 1/2. The whole house is fitted at 1/2 after that.


My goal is to reduce the loss of water pressure when multiple fixtures are on at different parts of the house.


If I upgrade the main "trunk" to 3/4 and branch off to tie into the multiple different 1/2 using 3/4,3/4,1/2 T fittings would pressure loss be less? For instance currently if someone turns on the kitchen sink while someone is in the shower, water pressure is noticeably reduced.


I guess it also comes down to a question of overall water pressure coming into the house. I don't know if pressure is restricted based on the 1/2, or the native pressure coming into the house or both.


What do you guys think? Would upgrading the main feed inside the house to 3/4 have a positive different or would I just be wasting my time?


Thanks!

Your looking for flow, not pressure.
A 3/4" line will have about twice the avalible flow so the pressure will seem higher.
Yes, it will make a big difference.

I'm looking to do the same thing. Are you doing the work yourself or hiring a plumper?
