Is the problem one fixture or the whole house?
Start with a simple test. Turn on one faucet at a time and compare. If only one fixture is weak, the cause is local. A clogged aerator, a worn cartridge or a half-open stop valve is usually the fix. If every fixture is weak, check the main valve at the house. A valve turned only partway after earlier work is a common cause. After that, look at the meter valve, the pressure regulator and the condition of the piping.
Quick sorting guide
| Symptom at the tap | Probable cause | What to do next |
|---|---|---|
| One faucet weak | Clogged aerator or cartridge | Clean the aerator or see faucet repair |
| Hot water weak only | Water heater valve or sediment | See water heater repair |
| Whole house weak | Regulator, partly closed main or narrowed pipe | Book a pressure test |
| Pressure swings high and low | Failing pressure regulator | Book a pressure test |
| Sudden drop and a wet yard | Service line leak | See water line repair |
What a pressure test shows
A pressure gauge screws onto a hose bib and reads static pressure with no water running. Many codes cap static pressure near 80 psi, and homes tend to feel weak below roughly 40 psi. Readings far outside that range point to the regulator or the supply.
A second reading with water running shows how much pressure drops under load. A large drop suggests narrowed pipe or a restriction. The plumber then works from the meter toward the house, section by section.
Common causes in homes around Brighton
Mineral buildup is common wherever water carries hardness. Thornton's 2025 water quality report lists hardness from 152 to 356 milligrams per liter, about 13.5 grains per gallon on average. The City of Brighton's 2023 report lists wells in the Beebe Draw aquifer plus purchased supply from Thornton and Denver Water, but it does not list a hardness number. Scale builds in aerators, shower heads, water heaters and older galvanized pipe.
If you use a softener, a clogged resin tank or valve can restrict flow too. Read about softener service if that applies.
Pressure dropped and you do not know why?
Describe what you see and the dispatcher will tell you whether it sounds like a quick fix or a longer diagnosis.
When there is no water at all
- Check whether neighbors have water. A street outage is a utility issue.
- Look at your water bill and mail for a shutoff notice.
- Check the main valve at the house and the valve at the meter.
- Look for a frozen line if temperatures dropped overnight.
- Call and describe the situation. The dispatcher can tell whether a plumber is the right call.
A frozen supply line is a common winter cause. Read more on frozen pipe repair.

Questions callers ask us
If neighbors report the same issue, the cause may be the utility. If pressure is fine at the meter but weak in the house, the problem is on your side. A gauge on a hose bib helps sort it.
It is a bell-shaped valve near the main that lowers street pressure to a safe level for the house. When it fails, pressure can swing high, low or both.
Sediment in the water heater or a partly closed valve is the usual cause. A plumber checks the heater outlet and nearby valves.
Yes. A leak steals flow before it reaches the fixtures. A meter check with everything off helps confirm it.
Scale narrows aerators, shower heads and older pipes over time. The effect is gradual.
Call and explain. The leak must be found and repaired before service can be restored. The dispatcher can help you plan the order of work.
The line is answered 24/7. Complete loss of water or a rapidly worsening leak is treated as urgent.
