What pressure should my house run at?

A comfortable, safe range is roughly 50 to 70 psi. Code caps household pressure at 80 psi, and above that a PRV is required.

How long does a PRV last?

Ten to fifteen years is common. They fail gradually, so a house can drift into high pressure without anyone noticing until fixtures start leaking.

Do I need an expansion tank with a PRV?

Yes. A PRV makes the system closed, so heated water has nowhere to expand. Without a tank you get pressure spikes and a dripping relief valve.

Could high pressure be causing my banging pipes?

Frequently. High pressure and missing arrestors are the two usual causes of water hammer.

How much does a plumber cost in the Denver metro?

Cost depends on the job, not a flat menu. Afford-A-Rooter scopes the work first, then gives you a free quote before anything starts, so you approve the number in advance. Drain and rooter calls sit at the lower end. Sewer line and water line repairs sit higher because they involve locating, access, and restoration.

How fast can you get here, and how long will the work take?

Most standard repairs are booked for the next available window and finished in one visit. Drain cleaning and fixture work usually take a few hours. Sewer and water line work can take a day or more because of excavation and inspection. You get a realistic time window up front, not a guess.

Do you handle emergency plumbing at night and on weekends?

Yes. Afford-A-Rooter runs 24/7 emergency plumbing across the Denver metro. Call for active leaks, sewage backups, no hot water, and burst pipes. Shut off the water at the main valve first, then call so we can stage the right truck.

Is your plumbing work guaranteed, and are you licensed?

Afford-A-Rooter is a Colorado Master Plumber and licensed Colorado State Plumbing Contractor, family owned and serving Denver since 2006. Work is performed to code, permitted where required, and backed by a workmanship guarantee. Manufacturer warranties apply to installed equipment such as water heaters.

Pressure Reducing Valve Installation and Replacement, Denver CO

Denver's terrain means some neighborhoods get street pressure far above what household plumbing is built for. A pressure reducing valve knocks incoming pressure down to a safe range. When the PRV fails, pressure climbs and fixtures start failing one after another.

What it is

Pressure reducing valve (PRV) A pressure reducing valve is a mechanical valve installed on the main water line into a house that lowers incoming city water pressure to a safer, more consistent level before it reaches the home's plumbing.

Denver's municipal water pressure can run high depending on elevation and location in the distribution system, and pressure that is too high shortens the life of pipes, valves, and appliances.

High pressure destroys the whole system, quietly

Above about 80 psi, code says you need a PRV. Sustained high pressure blows out supply lines, shortens water heater life, makes toilets run, and turns small drips into leaks. The valve is inexpensive compared to what unregulated pressure costs over a few years.

Stops water hammer caused by excessive pressure
Reduces water waste at every fixture
Required by code above 80 psi

Signs the PRV has failed

Banging pipes when a valve closes
Faucets that spray hard or splash
Toilet fill valves that keep failing
Relief valve on the water heater dripping
Repeated supply line or washer leaks
