TwistIIClean removes sand and sediment from your incoming water supply.

Simply flip the red safety latch and turn the top handle clockwise for 1/4 of a turn. This will flush your filter. Flush for 10 seconds, then slowly turn the top handle to it's original position and re-set the safety latch. Place a bucket under the purge point to catch the dirty water when flushing or connect a section of hose to the purge point to run the flushed water where you would like.

Rather than pipe size, TwistIIClean filter size is chosen based on flow rate. 3/4" - T2C-075: 0-25GPM 1" - T2C-100: 0-39GPM 1 1/2" - T2C-150: 0-78GPM

Most residential installations use 100 mesh, but the best mesh size depends on the particles in your water and what you use your water for. TwistIIClean uses four different screen mesh sizes for it's filters: 30 mesh (600 micron) - Removal of large particle matter. Pre-filtering ahead of other filters or devices. Large orifice impact sprinklers. 60 mesh (250 micron) - Typical landscape sprinklers. Pre-filter to fine cartridge filters. 100 mesh (150 micron) - Most popular size. Used for residential systems and pre-filtering before water treatment systems. 140 mesh (105 micron) - Drip-irrigation, micro-sprays, spray nozzles, misting systems. 200 mesh (74 micron) - Greatest protection. Often used on water treatment systems

Each TwistIIClean unit should be installed in a vertical position with the purge opening facing down. In cases where space is a concern, the TwistIIClean can be installed up to an angle of 45 degrees. Any more than that should be avoided or the filter will not perform as well as it could.

This can be due to heavy sediment load. To clear coarser sediment from the supply before filtering finer particles for your intended water use, you can place a second TwistIIClean upstream of the first with a coarser screen in it to act as a pre-filter to the downstream TwistIIClean.

TwistIIClean filters are not specifically designed for chemically treated water, as very harsh chemicals may adversely affect the filter components and the performance of the filter. For best results, chemical injection, if used, should be done downstream of the TwistIIClean Filter.

This product should not be placed downstream of water heaters or water over 120°F (49°C).

Algae growth in the filter bowl is caused by exposure to sunlight. Algae growth can be reduced by installing the filter in a shaded area. Alternatively, this problem can be prevented by installing a TwistIIClean Sun Shield designed specifically for the TwistIIClean Filters. The TwistIIClean Sun Shield is a black neoprene woven cover that slips over the clear bowl to prevent growth of algae and other organics.

If your filter does not clean itself thoroughly after back-washing, you may need to clean or replace your filter element of embedded sediment. In the event that you need to remove the internal filter screen, you should shut off the water supply, remove the filter bowl (by turning it counter clockwise), and finally remove the filter element. Installation is simply the reverse of the removal. Check out our video on how to remove/replace the filter elements. On the T2C-075 and T2C-100, this is achieved removing the holding pin at the top and pulling the element straight down. On the T2C-150, it is achieved by gently pulling on the clips holding the filter element in place until it can be pulled straight down. Pulling these clips too far may damage the filter. To reinstall, reverse the procedure, making sure the O-ring at the top of the bowl is in place.

A number of components are available for replacement such as the elements, bowls, red latches, and O-rings. The main reason to replace elements is when filtered sediment, such as rust or iron, becomes too caked on it is no longer easy to clean it off. The bowls, depending on what is being filtered, can also build up sediment over time making it hard to clean and see inside the filter to see when flushing is needed. A few of the O-rings may wear down over time. Longevity depends on how often your filter is flushed, how often the element or bowl has to be removed for additional cleaning, and your water source and sediment coming through it. Performing flushes more often will help with build up and is recommended. Refer to our Repair Kits page to see what replacement part kits are available.

The TwistIIClean 3/4", 1", and 1 1/2" units have been certified by the National Sanitation Foundation to be safe for use in Drinking Water Systems under standards NSF 61 & 372.

Any filtering system will have challenges when it comes to filtering out algae from natural bodies of water. The filter unit will effectively filter the algae and sediment, but it may clog up much faster due to the nature of algae and how easily it clings to any surface, often making it harder to clean off. If your T2C gets clogged quickly when filtering a natural water source, it is doing its job as it is catching the algae and sediment. In situations like this, more may need to be done to filter the water at the intake point to reduce the amount of algae/sediment coming into the line. Options are: changing where the intake is to keep it from pulling in so much algae, sand, or sediment; installing a self cleaning filter head at the intake; or installing a filter at the intake point. These options may help with this issue. Sometimes purchasing a more complex, higher-end filter unit at a higher cost may be required.

Sometimes a full TwistIIClean unit may need to be replaced depending on the amount of use it gets and the type of sediment that it is filtering. Over time some of the O-rings or other components may wear down and need to be replaced. If your filter unit is plumbed in and there is no easy way to replace the unit without hiring a plumber. This will essentially replace everything but the main housing that is plumbed into place. This is only for the 3/4" and 1" units. The 1 1/2" unit will need to be removed entirely as there is no easy way to replace inner components without it leaking afterwards if you cannot access the inlet and outlet openings.
