Frequently Asked Questions

1. Question:  
What can the TwistIIClean remove?
 
  Answer:  

Sand and sediment

     
 
2. Question:  
How do you clean the filter element?
 
  Answer:  

No need to turn off the water supply. Just flip the red saftey latch and then turn the top handle clockwise 1/4 turn. Wait 10 seconds, then slowly turn the top handle back to its original position and set the red safety latch.

     
 
3. Question:  
What size filter should I use?
 
  Answer:  

The main criteria for selecting the correct filter size is flow rate, not pipe size. LAKOS TwistIIClean filters are designed to operate in the following flow ranges:
 
T2C-075 (3/4”):  0-25 US GPM
T2C-100 (1”): 0-39 US GPM
T2C-150 (1 ½”):  0-78 US GPM
 
Pipe fitting adapters can be used with LAKOS TwistIIClean filters to accommodate the size of your water supply pipe size. More details about selecting the right size filter, including filter specifications, is shown in LAKOS Publication LS-870.

 

     
 
4. Question:  
What screen mesh size should I use in my filter?
 
  Answer:  

The optimum mesh size depends on the size of the sediment particles in your water and the intended use of the water.  LAKOS offers four different screen mesh sizes for the TwistIIclean filters:
 
30 mesh (600 micron)
60 mesh (250 micron)
100 mesh (150 micron)
140 mesh (105 micron)
 
The most common mesh size used in residential applications is 100, but you may benefit from a screen with finer or coarser mesh depending on water quality and end use of the water being filtered.
 

     
 
5. Question:  
Why does my filter require back-flushing so often?
 
  Answer:  

You may need to go to a coarser screen size which will allow smaller sediment particles to pass through and not be trapped by the filter.  If this is undesirable because of a very heavy sediment load or because the end use of the water requires the screen mesh size chosen, you may elect to install a LAKOS sand separator upstream of the TwistIIClean filter to remove separable solids from the water before it enters the TwistIIClean filter. 

For more information about sand separator products, go to: http://www.lakos.com/applications/sand-residential.html.

Another method is to place a second TwistIIClean upstream of the first with a coarser screen in it to act as a pre-filter to the downstream TwistIIClean.   

     
 
6. Question:  
Is the T2C filter designed for chemically treated water?
 
  Answer:  

LAKOS 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.
   

     
 
7. Question:  
Can I use the TwistIIClean for filtering hot water?
 
  Answer:  

The TwistIIClean filter is not recommended for hot water applications above 120 degrees F (49 degrees C).  The TwistIIClean Filter should be installed upstream of water heaters. 

     
 
8. Question:  
What can I do about algae growth inside the filter bowl?
 
  Answer:  

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 LAKOS 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. It is an optional accessory. Refer to part number information in LAKOS Literature LS-866.

     
 
9. Question:  
How do I remove the filter cartridge (screen) from the TWISTIICLEAN?
 
  Answer:  

Following are the steps to be taken to remove the internal filter screen:

1. Shut off water supply to filter.

2. Remove the filter bowl by turning the bowl counter-clockwise.

3. Remove the filter element:

a. On the T2C-075 and T2C-100, the element is removed by removing the holding pin at top of the element and pulling straight down on the element.

b. On the T2C-150, the element is held in place by clips attached to the inner body that hold the element in place. To remove the element, gently pull out on the clips just far enough to allow the element to be pulled straight down. Use care not to pull the clips out more than needed to lower the element as this can damage the filter.

4. Once the element is removed, rinse inside and out with clean water. A soft bristle brush may be used to loosen embedded sediment from the screen. Do not use a metallic brush as this may damage the screen.

5. To re-install, reverse the procedure above making sure that the o-ring at the top of the bowl is in place.


10. Question:  
How do I manually clean the TWISTIICLEAN filter?
 
  Answer:  

If the filter does not clean thoroughly after backwashing, removal of the filter element may be necessary. Following are the steps to be taken to clean the filter manually:

1. Shut off water supply to filter.

2. Remove the filter bowl by turning the bowl counter-clockwise.

3. Remove the filter element:

a. On the T2C-075 and T2C-100, the element is removed by removing the holding pin at top of the element and pulling straight down on the element.

b. On the T2C-150, the element is held in place by clips attached to the inner body that hold the element in place. To remove the element, gently pull out on the clips just far enough to allow the element to be pulled straight down. Use care not to pull the clips out more than needed to lower the element as this can damage the filter.

4. Once the element is removed, rinse inside and out with clean water. A soft bristle brush may be used to loosen embedded sediment from the screen. Do not use a metallic brush as this may damage the screen.

5. To re-install, reverse the procedure above making sure that the o-ring at the top of the bowl is in place.
