Too little or too much, at the tap
Water pressure problems in Aurora
Low pressure at one faucet is not low pressure in the street. High pressure that hammers the pipes is not a clogged aerator. The fix depends on which of those you have.
One fixture or the whole house
One slow faucet, with normal flow everywhere else, is usually that faucet's aerator, cartridge, or supply stop. That is fixture repair. Every cold fixture weak, or every fixture weak, can be a pressure-reducing valve, a partly closed house valve, a crushed line, or the utility's supply. Ask whether neighbors on the same main are affected. If they are, call the water utility before you replace a valve. Arvada asks its customers to report low pressure, main breaks, and dirty water at 720-898-7070. That is Arvada's number, for Arvada utility customers, not a link and not Aurora's desk.
This guide does not claim Aurora's water is hard, and it does not blame pressure on scale without a test. A softener is treatment, a different decision.
High pressure and water hammer
A reducing valve that has failed open can feed the house more pressure than fixtures like. The symptom is a loud closure, weeping stops, or a relief valve that drips at the water heater. Ask for a pressure reading at a hose bib with no water running, and ask what number the plumber thinks is too high. Do not let a reading become a repipe. A buried leak can also drop pressure. If the meter moves with the house off, go to leak detection before you replace the regulator.
Questions to settle first
Only the kitchen faucet is weak. Is the main failing?
Unlikely. One fixture points to that faucet, its aerator, or its stop. Check the other sinks and a tub. Whole-house weakness is when several rooms, hot and cold or all cold, drop together. Then look at the regulator, the house valve, and the utility.
Neighbors have no pressure either. Who do I call?
The water utility on the bill, before a plumber replaces parts in the house. Arvada publishes 720-898-7070 for its customers to report low pressure and main breaks. Aurora Water and Denver Water publish their own numbers. Use the utility that serves the address.
Can high pressure mean I need new pipes?
Not by itself. A failed reducing valve is a valve. Pipes get replaced when they are leaking or damaged, not because a gauge read high for an afternoon. Ask for the reading and the valve, and approve pipe only where it is actually failing.
Is this a water-quality problem?
No. Pressure is flow and force. Taste, odor, and hardness are treatment questions, and this guide will not call Aurora's water hard without a test. Do not buy a softener to fix a clogged aerator. Ask them to write that limit into the quote before you compare it with another company.
