Testing Shower Valve Pressure: A South Fulton Guide

The shower head

Unscrew the shower head and run the water — if the flow is strong without it, the head is clogged and needs cleaning or replacing.

The valve

If the flow is still weak with the head off, the valve cartridge or the supply to the valve is restricted.

The house

A pressure gauge on a hose bib shows the whole-house pressure, and a low reading points to the main or the regulator.

The compare

Test the hot and cold separately, since a weak hot side points to the water heater or its valve. hard water and humid conditions are common, and many older homes still have aging galvanized lines In South Fulton, pressure can vary by floor.

The head

Remove the shower head and test the bare flow first. If it is strong without the head, the head is the clog, not the valve.
