 Building codes for water pressure?
Author: Catwntrstn (FL)

Are there building codes for water pressure? I sold a home in Georgia and inspection said I needed to get a plumber to increase the water pressure. I did so. I now live in Florida and have really low water pressure on a brand new home under warranty. Want to know if there are actual codes/laws that have to be established - or, of course, a certain PSI that has to be maintained. How can I find the code/law? I don’t even know what a low, medium or high PSI is. I just lost my husband to Alzheimer’s in October and trying to do things on my own…
Thanks for any info!

Minimum is 15 psi, maximum is 80 psi.

Remember; 'code' is MINIMUM standard, not necessarily good practice

good practice would be 40-50 psi

15 psi through a 1/2" tube will deliver MUCH LESS volume (flow rate) than through a 3/4" tube

the ratio will be 1:2
