What is a ceramic cartridge faucet?

A ceramic disc faucet actually has two fire-hardened ceramic discs—an upper one that moves and a fixed lower one. The two discs move against each other in a shearing action, blocking water or allowing it to pass through. Ceramic disk faucets are nearly maintenance free and are generally guaranteed not to wear out.

What is a compression faucet?

Compression faucets have two separate handles. When the handle is turned, it raises or lowers a washer or seal that closes against a valve seat at the base of the stem to restrict water flow through the faucet body when you turn the handle off.

How do I remove a faucet cartridge?

Unscrew the screw on the handle and then lift the handle up to remove it from the assembly. Use water pump pliers to remove the plastic retaining nut. Lift the faucet spout straight up to remove it. Pull out any retaining clip using needle nose pliers.

What is a cartridge in a shower faucet?

Cartridge valves are one of four types of valves that you’ll find inside a faucet, and they are particularly well-suited for shower faucets. A cartridge has holes that regulate water flow and temperature when you turn the handle, and it offers more precise control than other types of faucets.

What is a ceramic valve?

A ceramic valve is a valve with ceramic trim, ball, seat, disc or lining. A carbon or stainless steel body is used to protect the ceramic trim from being damaged by sudden thermal or mechanical shock. Advanced ceramics are used in the manufacture including alumina, zirconia and silicon nitride.

What is the spline on a tap?

The next thing to check is the number of teeth on the spline (this is the top part of the valve which connects into the handle). Most of our valves are 7.6mm dia which is by far the most common diameter size, and fits onto the most common tap handle hole size of 8mm.

How long does sink faucet last?

Kitchen sinks made of modified acrylic will last 50 years, while kitchen faucets will work properly for about 15 years. The average life of bathroom shower enclosures is 50 years. Showerheads last a lifetime, while shower doors will last about 20 years.

How do I remove the aerator from my faucet?

Wrap the jaws of a pair of pliers with tape to keep them from scratching the aerator. Unscrew the aerator body from the faucet and remove all the internal components. Clean and reassemble. If you get weak water flow when you turn on the faucet, don’t assume your water pressure has suddenly gone bad.

Why do you need an aerator on a faucet?

Conservation and energy reduction. Because the aerator limits the water flow through the faucet, water use is reduced as compared to the same time of flow without an aerator. In the case of hot water, because less water is used, less heat energy is used.

How does an aerator on a faucet work?

What is a Tap Aerator and how does a Tap Aerator Work? The aerator acts as a sieve, separating a single flow of water into many tiny streams which introduces the air in to the water flow. Also as there is less space for the water to flow through, the water flow is reduced, resulting in water savings.

How do you aerate water?

Aeration brings water and air in close contact in order to remove dissolved gases (such as carbon dioxide) and oxidizes dissolved metals such as iron, hydrogen sulfide, and volatile organic chemicals (VOCs). Aeration is often the first major process at the treatment plant.

Do bubbles oxygenate water?

However, almost all of the oxygen dissolved into the water from an air bubble occurs when the bubble is being formed. Only a negligible amount occurs during the bubbles transit to the surface of the water. This is why an aeration process that makes many small bubbles is better than one that makes fewer larger ones.

What can increase dissolved oxygen in water?

Dissolved oxygen concentrations are constantly affected by diffusion and aeration, photosynthesis, respiration and decomposition. While water equilibrates toward 100% air saturation, dissolved oxygen levels will also fluctuate with temperature, salinity and pressure changes ³.

Is high dissolved oxygen good?

External bubbles (emphysema) can also occur and be seen on fins, on skin and on other tissue. Aquatic invertebrates are also affected by gas bubble disease but at levels higher than those lethal to fish. Adequate dissolved oxygen is necessary for good water quality. Oxygen is a necessary element to all forms of life.

What happens when dissolved oxygen is too low?

Low dissolved oxygen (DO) primarily results from excessive algae growth caused by phosphorus. As the algae die and decompose, the process consumes dissolved oxygen. This can result in insufficient amounts of dissolved oxygen available for fish and other aquatic life.

What causes oxygen deprivation?

Anemia and carbon monoxide poisoning are common causes of hypemic hypoxia. Ischemic hypoxia ( or “stagnant hypoxia”) – Reduced brain oxygen is caused by inadequate blood flow to the brain. Stroke, shock, cardiac arrest and heart attack may cause stagnant hypoxia.

What does it mean when dissolved oxygen is low?

Dissolved oxygen (DO) is one of the most important indicators of water quality. It is essential for the survival of fish and other aquatic organisms. Oxygen dissolves in surface water due to the aerating action of winds. Oxygen is also introduced into the water as a byproduct of aquatic plant photosynthesis.

What is BOD in water?

Biochemical Oxygen Demand (BOD, also called Biological Oxygen Demand) is the amount of dissolved oxygen needed (i.e. demanded) by aerobic biological organisms to break down organic material present in a given water sample at certain temperature over a specific time period.

Where can dissolved oxygen be found?

Dissolved Oxygen (DO) is found in microscopic bubbles of oxygen that are mixed in the water and occur between water molecules. DO is a very important indicator of a water body’s ability to support aquatic life. Fish “breathe” by absorbing dissolved oxygen through their gills.

Do fish breathe dissolved oxygen?

Fish use a specialized organ called gills in order to breathe the oxygen dissolved in water. The mouth and throat of a fish force water over the gills. Gills have a lot of blood vessels. The water has a higher concentration of oxygen than the blood.

What is dissolved oxygen level?

It is essential for all plants and animals. Oxygen availability throughout the year is influenced by other chemicals present in the water, biological processes, and temperature. A dissolved oxygen test measures the amount of oxygen dissolved in the water. Photosynthesis of aquatic plants releases oxygen into the water.

What is a widespread faucet?

Standard faucet drillings are centerset, single-hole or widespread. Centerset. These faucets are made for basins with three holes and have handles that are 4 inches apart. They combine a spout and handles on a single base unit. Some centerset faucets may have two handles mounted onto a 6-inch plate.
