Frequently Asked Questions

How do we get clean, safe water?

Despite using and benefitting from drinking water and wastewater systems multiple times every day, most of us don't even think about or know how these systems work. It takes a lot, in terms of natural, human, financial and other resources, as well as physical, chemical and biological processes, to bring clean, safe drinking water to your home and to deal with the waste you produce from a toilet or washing machine. These interactive experiences explain some of what is required in treating water.



These sections of the RCAP website explain the treatment processes through the means of animated diagrams and short videos. Each of the two sets of videos is hosted by a member of RCAP’s field staff who provides an overview of the treatment process as well as special considerations or concerns that a system’s operator has in each step. The videos are meant to make non-operators more comfortable with the vocabulary and terms that a plant’s operator uses and to help a utility’s decision makers understand what is required to operate a dependable and sustainable water utility in terms of natural, human, financial and other resources.

Where does waste water go?

Where wastewater goes depends on the process being used. If the wastewater is going into a septic tank, it's being sent from a building to an underground storage container. In the container, bacteria will break the solid waste down and only the wastewater will flow through a filter to a second take. From there, it filters out of the tank and into the ground below. The ground is prepared with sand, gravel and other debris that filters the water further so that the ground water is clean.

Sewer Treatment
If not a septic system, wastewater goes to a waste treatment plant. At the plant, the water is put into different holding tanks as the water is cleaned. Bacteria are added to the beginning tanks to break down the solid waste that's pulled off the rest of the water. In other tanks, oil and other particles that might float to the surface--such as grease--is skimmed off and removed. Filters are also used to remove smaller contaminants and chemicals from the water. Once all particles are out of the water that can be removed, the water is placed in containment ponds and chemically treated to kill any remaining microorganisms.

Last Stop
As with septic tanks, wastewater is eventually returned to nature. It's either allowed to slowly seep into the ground from containment ponds or is sent back into streams, rivers or lakes. In some cases, the water will be so clean that it can be used for farm irrigation.

How Tankless Water Heaters Work?

It's the holiday season and your peaceful suburban domicile is overflowing with houseguests. You need a nice, hot shower to soothe your nerves, but you're in line behind your in-laws and cousins. In times like these, you'll be glad you installed that new tankless water heater in your garage. The idea behind a tankless system is that it heats the water as you need it instead of continually heating water stored in a tank. Tankless heaters have been the norm in much of Europe and Japan for quite some time, but they haven't gained popularity until recently in the United States -- largely due to the green movement. If you're a good candidate for a tankless system, you can save a substantial amount of money every year on your monthly bills while at the ­same time conserving natural gas. Tankless heaters also last about five to 10 years longer than a tank heater, take up much less space and provide you with an unlimited amount of hot water.

In order to understand how a tankless water heater works, it's important to know how a standard tank heater operates. In a traditional heater system, there's a large tank that holds and heats water. In order to give you hot water when you need it, the tank continually heats the water to maintain a constant temperature. The energy used to keep the water hot even when it's not being used is called standby heat loss.

Tankless systems avoid standby loss by heating incoming water only as you need it -- they're also referred to as "on demand" water heaters for this reason. The elimination of the standby heat loss is what makes a tankless system more efficient.

In order to get you that piping-hot shower when you want it, a tankless water heater uses a powerful heat exchanger to raise the temperature. A heat exchanger is a device that transfers heat from one source to another. There are heat exchangers in your air conditioner, refrigerator and car radiator. In this case, it transfers heat generated by electric coils or a gas-fired burner to the water that comes out of your faucet. This exchanger is activated by the incoming flow of water. So when you turn on your hot water tap, the incoming water circulates through the activated exchanger, which heats the cold water to your preset temperature. All you need then is some soap and shampoo and you're ready to wash, rinse and repeat.

Natural Gas
Natural gas is a naturally occurring hydrocarbon gas mixture consisting primarily of methane, with other hydrocarbons, carbon dioxide, nitrogen and hydrogen sulfide.[1] Natural gas is an important energy source to provide heating and electricity. It is also used as fuel for vehicles and as a chemical feedstock in the manufacture of plastics and other commercially important organic chemicals.

Natural gas is found in deep underground natural rock formations or associated with other hydrocarbon reservoirs in coal beds and as methane clathrates. Petroleum is also another resource found in proximity to and with natural gas. Most natural gas was created over time by two mechanisms: biogenic and thermogenic. Biogenic gas is created by methanogenic organisms in marshes, bogs, landfills, and shallow sediments. Deeper in the earth, at greater temperature and pressure, thermogenic gas is created from buried organic material.

Before natural gas can be used as a fuel, it must undergo processing to clean the gas and remove impurities, including water, to meet the specifications of marketable natural gas. The by-products of processing include ethane, propane, butanes, pentanes, and higher molecular weight hydrocarbons, hydrogen sulphide (which may be converted into pure sulfur), carbon dioxide, water vapor, and sometimes helium and nitrogen. Natural gas is often informally referred to simply as gas, especially when compared to other energy sources such as oil or coal.

Portable Water
Drinking water or potable water is water safe enough to be consumed by humans or used with low risk of immediate or long term harm. In most developed countries, the water supplied to households, commerce and industry meets drinking water standards, even though only a very small proportion is actually consumed or used in food preparation. Typical uses (for other than potable purposes) include toilet flushing, washing and landscape irrigation.

Over large parts of the world, humans have inadequate access to potable water and use sources contaminated with disease vectors, pathogens or unacceptable levels of toxins or suspended solids. Drinking or using such water in food preparation leads to widespread acute and chronic illnesses and is a major cause of death and misery in many countries. Reduction of waterborne diseases is a major public health goal in developing countries.

Water has always been an important and life-sustaining drink to humans and is essential to the survival of all known organisms. Excluding fat, water composes approximately 70% of the human body by mass. It is a crucial component of metabolic processes and serves as a solvent for many bodily solutes. The United States Environmental Protection Agency in risk assessment calculations previously assumed that the average American adult ingests 2.0 litres per day.However, the United States Environmental Protection Agency now suggests that either science-based age-specific ranges or an all ages level (based on National Health and Nutrition Examination Survey 2003-2006 data) be used. Drinking water of a variety of qualities is bottled. Bottled water is sold for public consumption throughout the world.

What is a sewer lateral?

A sewer lateral is the underground pipe that connects a home or business to the main sewer line. Some local governments consider the entire connecting pipe to be the property of the homeowner or business owner.

In other places, a city or county will take responsibility for the section of a sewer lateral from the main line to the property line. Sewer laterals often make up more than half of the pipe in some systems. Unfortunately, the privately owned underground section of a lateral is often taken for granted until a problem erupts that can't be ignored -- such as raw sewage backing up into a home.

A number of things can compromise a sewer lateral. Foreign substances or objects like disposable diapers flushed down a toilet can sometimes create a clog. Tree roots can push through the side of a lateral. Or, over time, a very old sewer lateral pipe can simply corrode and crack.

E-Z Plumbing has years of experience in working with Sewer Laterals. We have successfully installed new sewer laterals for new home construction as well as repaired many for older homes. E-Z Plumbing can move or replace a damaged sewer lateral. We also can cable sewer laterals to clear out roots and clogs.

If you suspect an issue with your sewer lateral call E-Z Plumbing to have an expert check out your situation.

What is Copper Repiping?

Repiping is the process of replacing all existing domestic water piping by installing a new system throughout your home or building.

What are the benefits of copper repiping?

Copper repiping corrects problems and SAVES YOU MONEY! It is safe, strong, and dependable.

  • Great water pressure
  • Clean, clear water
  • Safe and sound plumbing system
  • Environmentally efficient

Repiping is a system wide solution that allows you to take a shower, wash dishes, water the lawn, wash laundry, and use all faucets and fixtures at the same time without reduction in water pressure. It gives you great water pressure throughout your home, improves delivery of hot water, eliminates water damage repair bills and saves money on water lost to an inefficient system.

Why Repipe?

If you answer yes to any of the following questions, repiping will correct your problems:

  • Are you experiencing low water pressure in your home?

    Low water pressure at a faucet, shower, or washing machine is caused by build up of rust and corrosion on the inside of galvanized iron pipes. As these pipes age, the rust and corrosion continue to build up restricting the flow of water.

  • Do you get scalded in the shower when someone flushes the toilet, turns on the faucet or washing machine?

    This is also due to low pressure caused by build up of rust and corrosion of galvanized iron pipes.

  • Do you get rust colored or yellow water?

    Rusty or discolored water is caused by the rust and corrosion from inside pipes mixing with the water flowing through the pipes. This indicates an advanced stage of corrosion. Iron pipes coated with zinc to prevent rust are galvanized iron. As galvanized iron pipes age, the zinc coating gradually wears away exposing the iron. The unprotected iron rusts rapidly from water. Most pre-1970 homes have this type of plumbing.

  • Have you had leaks in your plumbing?

    Leaks are most commonly caused by corrosion of the galvanized iron.

  • Do you have galvanized iron water pipes?

    Iron water pipes are coated with zinc to prevent rusting. Over time, they lose the zinc coating, the iron rusts, and becomes corroded restricting water pressure to faucets and showers.

    This condition also results in rusty or discolored water which indicates the pipes are in an advanced stage of corrosion. This corrosion will commonly cause leaks in the pipes, discolor water, as well as depositing rust particles in your drinking water.
