- Do I Need a PRV? IPC 604.8 and the Expansion Tank It Drags With It
Above 80 psi the code decides for you. What most people are not told is that fitting one closes the system — and where you set it then triples or thirds the expansion tank it now requires.
- Low Water Pressure in a House: Static vs Flowing, and What Each Tells You
One gauge reading diagnoses nothing. Static pressure tells you what the street gives you; flowing pressure tells you what the house destroys. The two readings together name the fault — with the friction numbers worked through.
- Normal Water Pressure for a House: 40 to 60 psi, and Why Height Costs 4.33
65 psi is 150 feet of head. Each storey costs exactly 4.33 psi whether water is moving or not — the one loss in the system independent of flow. And above 80 psi a PRV is code, not an upgrade.
