One fixture versus the whole house
One slow faucet usually means a clogged aerator, a cartridge, or a local supply issue. Whole-house low pressure points to a regulator, a main line, a hidden leak, or a supply problem. Check a hose bib pressure reading too, since it reflects the house supply.
Hard water and aging pipe
Scale narrows pipes and fixtures over time, and galvanized pipe narrows from rust inside. Both lower flow gradually, so you may not notice until a shower becomes a trickle. A pressure check and a pipe condition check separate scale from a failing regulator.

Frequently Asked Questions
How do I check my water pressure?
Use a gauge on a hose bib, or ask us to check it on a visit. We explain the reading and whether it is high, low, or normal for your system.
Why is pressure low only in the shower?
A clogged showerhead, a worn valve cartridge, or scale in the shower line are the usual causes, and all are fixable without touching the main supply.
Can high pressure be a problem too?
Yes. Very high pressure stresses joints, water heater parts and expansion tanks, and wastes water. A regulator and expansion tank check helps.
Does a water softener help pressure?
It can slow future scale, but it does not clear existing narrowing. A softener is a prevention step, not a repair for a clogged line.
