A Residential Plumbing in Long Beach CA system carries fresh water throughout the house to sinks, toilets, bathtubs, and showers. It also carries waste away to a public sewer or septic tank.

The visible interior supply, drain waste, and vent piping are made of many kinds of materials. A basic understanding of how these systems work can help homeowners maintain them.

Water Supply

The home plumbing system routes clean water to the fixtures and appliances that use it. This includes faucets, showers, toilets and washing machines. It also carries away wastewater and storm runoff. This plumbing system must meet stringent public health and safety regulations.

The system’s most important element is the water supply line that brings municipal water to your home. This line may be made from copper, steel or plastic tubing. It’s typically installed underground to protect it from damage or tampering. The water supply line runs from the water meter to your house, then branches out to deliver water to each fixture and appliance.

This drinking water plumbing system needs adequate inspections and maintenance from a professional plumber to minimize waste and leakage. The piping should be free of cross-piping with wastewater lines, which could transmit contamination.

The piping should be sized appropriately to meet fire-flow standards and maintain a pressure of 20 pounds per square inch gauge (psig). The higher the pressure, the better the water flow. Leaks in this plumbing system are a significant concern because they reduce water pressure and increase the cost of running water-related household appliances. An experienced plumber can repair most types of leaks quickly and inexpensively.

Water Heater

The water heater is the plumbing appliance that heats incoming cold water to supply your hot-water needs. This includes showers, tubs, dishwashing, laundry, and other household uses. Most homes have a tank-style electric or gas water heater but there are also hybrid and point-of-use systems that work with a home’s existing piping to provide instant hot water.

The water heater’s storage tanks are usually made of steel and are coated with glass lining to protect the metal from corrosion. The tanks may have magnesium anode rods to slow down the corrosive effects of water on the steel.

Your piping system runs from the water heater to your fixtures and appliances. Ideally, this piping is made of PEX (cross-linked polyethylene), which is becoming more popular for Residential Plumbing in Long Beach CA applications. Unlike copper, PEX does not rust or require soldering for joints. This pipe material is flexible and provides a good insulator to help prevent the formation of cold spots or freezing water inside the pipes.

Ideally, the plumbing manifold, which provides a connection to each fixture and appliance, is located in an easily accessible location such as a basement or service closet. This minimizes the amount of time it takes to shut off a single fixture and makes maintenance and repair easier. It also reduces the number of joints in a system, which helps to keep water pressure high.


The drainage system is designed to remove excess water from your property and keep sewer gases out of the building. It includes drain lines, traps and cleanouts that work with the piping to collect wastewater, remove it from your house and dispose of it in an approved manner.

Each plumbing fixture has its own drain line that connects to the main drain line. The main drain line is plumbed with a slope to help water flow freely; it leads to the city sewer system or your septic tank on your property. The piping in the drain system also includes vent piping that allows air into the system to ensure that drains function properly. If you notice an unpleasant smell in your home, it may be due to a blocked drain or clogged vent pipe.

Surface water drainage is for all the rainwater that falls on your property. This water flows down the gutters, into the patio and sports field drains and into a soakaway or river or stream. Foul water drains are for all waste water that enters the household plumbing, such as toilet paper, food scraps and human waste.

The drainage system must be in good working order to protect the structure from flood damage and to prevent sewer gases from entering the house. It’s best to have a plumber inspect your drainage system regularly, especially if you live in an older property with clay pipes.


The sewer is the drain line that carries all of your waste away from your home. It is one of the most important but least understood parts of your plumbing system.

The main sewer line takes the sewage that leaves your toilets, sinks, tubs and showers to the City’s sewer treatment plant or if you have a septic system it goes to your septic tank and field.

When non-biodegradable items are flushed they can cause clogs and blockages in the pipes that carry your waste to the City’s wastewater system or your septic system. Proper responses to clogs can minimize health effects and property damage. If you think you have a sewer problem please contact us.

Most modern homes have a house sewer line that is connected to the public sewer. Older homes may have combined sewer lines that accept both sanitary and storm water. These are becoming less common because they put a strain on the public wastewater treatment plants by also taking in rain water.

The City keeps maps that show where the sewer line is located on private properties. Before you start any digging around your home you should know where the main sewer line is so you don’t accidentally cut it. You can find this out by calling the previous owners or your local government.
