A weak shower can be the valve, the shower head, or the house pressure, and a quick test separates them. Knowing where the pressure drops tells you what to fix.
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. freezing winters put stress on exposed lines, and many older city rowhomes have aging supply lines In Harrisburg, 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.
