What to do right now
Check if it's one fixture or everywhere
One fixture = aerator, cartridge, or supply line. Everywhere = main valve, pressure regulator, or supply problem. This single test directs everything.
Clean the aerators
Unscrew faucet aerators and the showerhead, soak in vinegar to dissolve mineral scale, scrub, reinstall. This alone fixes a huge share of 'low pressure' complaints.
Check the main shutoff
Make sure the main valve is fully open — a partially closed valve after plumbing work is a classic gotcha.
Ask a neighbor
If neighbors have the same issue, it's the municipal supply — call your water utility, not a plumber.
Call for the deeper causes
Call (844) 699-1165. Failing pressure regulators, corroded galvanized pipe, and hidden leaks need a pro's diagnosis.
Stay safe
- Don't crank the pressure regulator up blindly — excessive pressure bursts supply lines and voids appliance warranties.
- Normal residential pressure is 40–80 psi; a $10 gauge on a hose bib tells you exactly where you stand.
Mistakes to avoid
- Replacing fixtures before checking the $0 aerator cleaning.
- Turning the pressure regulator to maximum — 100+ psi destroys washing machine hoses and water heaters.
- Ignoring gradually worsening pressure — corroded galvanized pipe only gets worse.
- Assuming it's 'just the city' without asking a neighbor or testing with a gauge.
What to tell the plumber when you call
Have these answers ready — it gets you the right pro faster and a more accurate quote.
- Whether it's one fixture, one area, or the whole house
- How long it's been happening and whether it's worsening
- Your home's age and pipe material if known (galvanized = prime suspect)
- Your pressure reading if you tested with a gauge
- Whether neighbors are affected
