      Technical Specifications:

      My DE filter is running at high pressure and has a slow flow of water returning back to the pool.
      The DE filter is loaded with too much debris or algae and needs backwashing or regeneration. If this problem persists and you notice the filter gauge pressure rising from 7-10 psi above your beginning pressure, you need to regenerate you filter. Refer to your owner’s manual for further instruction.
      Your pump output might exceed the design flow rate of the filter. Make sure the pump is correctly sized for your filter.
      If there is algae in the pool, super chlorinate, backwash or bump/drain and recharge as needed. Make sure you are properly backwashing on your vertical grid filter. Refer to your Owner’s manual for instruction.
      My DE filter short cycles even after I backwash or regenerate and recharge.
      The filter elements may be clogged because of an accumulation of chemical deposits. Clogging is accelerated if chemicals are fed through the skimmer, operating your filter too long without DE after starting the pump, or operation the filter without DE. DE must be added as soon as the filter is full of water, and the pump is putting out a steady stream of water.
      Biguanide based sanitizers (Splashes/ Baquacil) can cause short cycling.
      My DE is leaking back into the pool.
      Be sure that the suspected material on the pool floor is actually DE. Pollen, chemical residue and plaster dust often look like DE.
      You may have a tear in your filter elements, replace if necessary. Make sure that you assemble the internal parts properly.
      Check for air leaks, as this will cause the system to leak DE back into the pool. If there are air leaks, install a check valve between the pump and the filter valve.
      My DE filter has short cycles when vacuuming.
      This is normal if the pool contains very dirty water. Backwash or regenerate and recharge more often. If there is a presence of live algae, add enough chlorine sanitizer to control this growth, and then vacuum. The presence of alum of flocking agents will clog the filter. Vacuum so as to bypass the filter. Do not use flocking agents with DE filters.
      Will backwashing or regenerating my DE filter thoroughly clean my filter?
      No, you must thoroughly clean the elements at least once a year. You can clean your filter elements using automatic dishwater detergent. Remove the elements from the filter, according to the Owner’s Manual, and hose them off with a forceful stream of water from your garden hose. Fill a large plastic container with warm water and add about ½ a cup of detergent. Soak the elements for approximately 3-4 hours. After soaking, rinse off the elements again. Re-assemble your filter according to the instructions in the Owner’s Manual. NOTE: do not soak elements in muriatic acid if the pool uses Biguanide products. This will damage the filter.
      You may choose to clean the elements with muriatic acid or other commercial filter element cleaners, mix according to the package instructions. Use extreme caution when handling any cleaning agents, as they can be harmful to the eyes, skin and clothing. After cleaning, thoroughly rinse all elements with cold water.
      How often do I need to change the DE?
      Whenever you backwash your DE filter allowing the dirt and DE out the waste line or when you regenerate and drain your filter.
      The pool won’t stay clear.
      Your pool chemistry may be out of balance, allowing algae to multiply.
      The flow rate through the filter may be low due to clogged or undersized piping. Cleaning the lines or changing to larger pipes will correct this problem.
      Your filter operation time may not be long enough to compensate for heavy use or hot weather. Try running your filter for 24 hours to clear the water, then adjust to less running time.
      Your pump may be hooked up to the wrong port on the multiport valve. If incorrectly installed, the filter will be flowing in reverse. Be sure the pump is connected to the port marked "pump" on the valve.
      You could be backwashing too often. Backwash only when the pressure rises 7-10 psi over the starting pressure, or when the return flow back into the pool becomes low.
      Filter Sizing Advice
      To ensure proper filtration and a trouble-free season: Your pool's size (total gallons) should be equal to or less than the Maximum Pool Size listed for each of our systems. Maximum Pool Size is based on an 8-hour turn-over rate.

      Since our high efficiency systems completely turn over your pool water in less time than standard 12-hour systems, you save money by running your filter less!

      When sizing a replacement pump, Dr. Pool strongly suggests that you replace with the same size horsepower as your existing set-up! In most cases, up-grading horsepower shortens your filter’s expected life and voids manufacturer’s warranties.
