Accent Plumbing is a service company, not a sales company. We work with our customers to help them understand their problems and reasonable solutions to address those issues. Please click on any of the following sections to understand more about plumbing.  

Codes & Licenses

Plumbing Code
The World Health Organization recognizes that “sustainable health, especially for children, is not possible without access to safe drinking water and basic sanitation facilities”. Plumbing codes are designed to keep us healthy and safe.

There are two main plumbing code books that the country follows, the International Plumbing Code (IPC) and the Uniform Plumbing Code (UPC). The state of Arizona tests to knowledge of the IPC. The IPC consists of several hundreds of pages detailing the correct standards allowed for plumbing systems. This includes all supply piping, fixtures, and drain piping.

Accent Plumbing is licensed for both residential and commercial work. We have held our license continuously since 1971. We follow the codes to ensure your house is built or repaired properly. You can view our licenses at the Arizona Registrar of Contractors.

How Plumbing Works

The Basics of Plumbing
We use pressure and gravity to help water flow. Plumbing is roughly broken down into two systems, the supply system and the drainage system. The supply system mostly utilizes pressure and the drainage system mostly utilizes gravity. These two systems must be separated in order to prevent the drain system contaminating the supply system.

Supply System
The supply system typically starts at the city meter and runs to the house. The line from the meter to the house is called a “service line”. Where the pipe rises from the ground is known as a “riser” and typically has a shut off to stop all pressurized water from entering the house. You can test the pressure to your house at that riser. You want your pressure to be somewhere between 40 – 80 psi. Once the supply water has entered the house, the water then splits to the water heater and to all of the fixtures throughout the house.

Drain System
Once water has been used by a fixture, it hopefully goes down the drain. Drains use a p-trap to prevent sewer odors from coming back into the house. Each fixture has a different sized drain line associated with it. These drain lines join together underneath the house to run out to the city sewer or septic tank. This single line going out is called the “main line” and should have cleanouts installed to help recover from any blockages in the pipes. The drain system includes three parts, drain, waste, and vent (DWV). All three of these are important to keep everything moving out of your house.

Types of Pipes

There are many different materials that have been used over the years. Every pipe has its own pro’s and con’s, but as a general rule, plastic pipe should not be exposed to UV rays, as they can break down very quickly. Below is a chart that gives a high level breakdown of where the pipe can be found in a plumbing system

Acrylonitrile Butadiene Styrene is used for drainage piping. It is a very cost-effective material and does not have a heavy weight. It holds up well for drain systems and can have very solid connections keeping roots out.

Is used for gas piping and fire sprinklers. It is the cheapest steel pipe option but is not allowed to be installed outside.

May be used for both supply and drain piping. It is a great transition material to use to connect galvanized steel and copper. Brass is the most expensive pipe to run water and is best only used in small lengths.

Is a drain line that has been around for decades. It was used for all residential drain lines until plastic piping became the standard. Commercial properties continue to use cast iron for drain lines due to fire codes (the pipe does not burn or melt in a fire). Most houses that have cast iron piping are starting to develop issues.

May be used for both supply and drain piping. It comes in different thicknesses and is available in both rigid and flexible tubing. Copper is not compatible with galvanized steel and must have at least a dielectric union in between the two metals.

Corrugated Stainless Steel Tubing is used for gas lines. It is a flexible style pipe that allows for quick runs in the attic and down the walls with minimal fittings.

Chlorinated Polyvinyl Chloride is similar to standard PVC but can withstand a much higher temperature. It may be utilized inside of the house. It can become very brittle and crack over time.

Is used for supply, drainage, and gas lines. It requires a thread at each end to be screwed into every fitting. Galvanized steel is not compatible with copper and must have at least a dielectric union between the two metals

Cross linked Polyethylene pipe is used for supply piping. It has been the standard supply pipe for new homes since the early 2000’s. There are three types of pipe; A, B, and C. These differences are in how the pipe is produced. We carry type A, which has the ability to expand onto fittings

Is no longer legal within the state of Arizona. It was installed in new homes throughout the 80’s and 90’s, but there were several issues with the pipe and fittings that caused harm to many people. If you have this pipe, we would strongly encourage a repipe.

Is used for gas piping. It may not be used for inside piping and is only for exterior underground.

Polyvinyl Chloride is a very durable and cost-effective material. It may be used for drain lines and any supply lines that are outside. It is commonly used for outside sprinkler lines. It may not be used for interior supply.

Shut Off Valves

A shut off valve is very important for managing the flow of water in your house. Shut off valves come in several different styles, but the two most popular are gate valves and ball valves. Gate valves move a “gate” up and down inside of the pipe as the handle is turned. These valves typically lock up inside of the valve and should be replaced whenever they malfunction. Ball valves utilize a ball inside of the valve that rotates 90 degrees to turn on and off. These valves are much more reliable, but they should be cycled periodically to prevent calcium build up.

Angle Stop
Angle stops are the localized shut off valves. They are located below almost all fixtures in the house. Every faucet and toilet should have an angle stop installed as the water comes out of the wall. Shower valves may have integral stops integrated into the valve. This allows the homeowner to shut off the water to a specific faucet without needing to shut off and drain the entire house. It is a good idea to cycle the valves at least once a year to break up all of the calcium buildup that can occur.

My wife and I have had the pleasure of utilizing Accent Plumbing four times in the last 3 years. Regardless of the situation, wall leak, water heater, multiple toilet replacement, or pipe inspection. Each time the professional that came to our home was, knowledgeable, experienced, friendly and efficient. They provided the service and product required and never pushed us toward something we didn't need or want. From the friendly greeting when I called their office to the happy plumbers, Jim, Steve, Jason, and Bennett (I'm sure I missed one or two) we felt like we were in good hands. And received this service for a surprisingly reasonable fee each time. Thank you Accent, I repay you for your great service every time I recommend you to my friends!

Calling a plumber is usually not fun. But Accent’s service is so good and straight forward, that I have comfort the problem will be resolved quickly for fair value. We’ve called Accent twice. On the most recent occasion, we received a text message 30 minutes before the plumber arrived. He was very courteous and professional and got the job done and left. We received an email with a link to make payment by credit card and a follow up call from the office to make sure everything met our needs. Simple. Done. Accent will be our go-to from now on.

Very good experience with Accent Plumbing! A couple days before I left Arizona for Christmas, my downstairs neighbor realized I had a leak from my shower. He needed the leak fixed ASAP, so I called up Accent Plumbing. The staff member on the phone was super nice, and she helped me set up an appointment. She was very receptive to special instructions I had about who to contact to be let in to the apartment and to note my credit card info to pay for the service. Unfortunately I don't have the name of the plumber that performed the service, but my friend who was at my apartment overseeing the process said they did a great job, and it even ended up costing much less than the estimate. Overall very happy with Accent Plumbing; they were a life saver!
