Basket Filter Replacement

Basket Filter
When the water in your kitchen sink swirls into the drain, it is entering the sink basket Filter. The stainless steel basket Filter is usually found in commercial and Industrial Filters applications, it strains food particles and waste and allows the water to flow freely into the sink drain opening.

The top of the Basket Filter is visible as a metal rim surround the sink drain. Below the sink, its metal walls gradually narrow in a basket shape, until they ultimately form a thin pipe, which interfaces with the sink tail piece. Over time, a basket Filter will wear out and this is first noticed as spin the first sign of this is a leak under the sink. When the piece corrodes and begins to leak, it needs to be replaced.

In their sink repair Magic Plumbing video, which can be found at one of their service men replaces a basket Filter underneath a kitchen sink in a restaurant. Most commercial sinks have a basket Filter, as opposed to residential sinks which usually have a sink Filter.

Over time basket Filters wear out. Repeated use, physical stress and the alternating contraction and expansion from exposure to hot and cold water take their toll, and cause the piece to corrode.

The first thing you might notice, when your Basket Filter corrodes, is leaky water under the sink. However, a leaky basket Filter is only one of the plumbing problems that can cause water leakage under the sink. To test if the problem is a leaky basket Filter fill your sink with water, and then gently touch a piece of tissue to the rim of the basket, where it appearsunder the sink. If the tissue fills up with water that tells you the basket Filter is leaking, and needs to be replaced.

Once you have determined that your basket Filter requires replacement, you must decide if you will replace the piece yourself or call a professional plumber. If you decide to make the repair, you will need to purchase a new Filter basket and tail piece. The tail piece is a short straight metal piece that connects the bottom of the basket Filter to the copper plumbing of the house. The copper pipes won't need to be replaced, in this replacement job. Now you will need to remove the old basket Filter.

Once both basket Filter and tail piece are removed, insert a new custom fitted tail piece into the top of the copper piping.Next, fit the Filter basket into the drain hole of the sink, from above. The lips of the basket will keep it from falling into the drain hole, however, before actually inserting the basket, you will want to add a ring of plumbers putty around the underside of the lips of the Filter basket to make a nice seal and prevent leaking.

The rest of the installation takes place under the sink. Tighten the nuts and washers that connect the copper piping tail piece and basket Filter. Don't over tighten anything as that may cause cracking. When everything is in place, turn on the water and check for leaks.

Industrial Filter

Activated carbon (AC) is a natural material derived from bituminous coal, lignite, wood, coconut shell etc., activated by steam and other means, and each one have different adsorption properties (e.g. bituminous carbon for high chlorine reduction capacity). We also use various blends of carbon to achieve specific water quality and contaminants reduction (e.g .coconut shell carbon for "sweet taste". The rapid gravity sand filters is a type of Industrial Filters commonly used in municipal water treatment facilities. Rapid sand filters use relatively coarse sand and other granular media to remove particles and impurities that have been trapped in a floc through the use of flocculation chemicals - typically salts of aluminium or iron. Water and flocs flows through the filter medium under gravity pressure and the flocculated material are trapped in the sand matrix. Rapid filters are usually built open with the water passing down the filter but by gravity. It has a filter rate of 4 – 8 m3/m2/hr. The tank is made of concrete with a depth of 3.0 to 3.5m. Coarse sand of size 0.4 to 1.5mm is used as the filter medium. A screen rapid sand filter is a type of filter utilizing a rigid or flexible screen to separate sand and other fine particles out of water for irrigation or other applications.

Typical screen materials include stainless steel (Mesh), polypropylene, and nylon.
