How To Clean Hayward Pro Grid De Filter Of Swiming Poolvn

DE pool filter cutaway D.E. puddle filters are superior filters, as compared to sand and cartridge filters, which cannot come close to D.E.'southward ability to remove particles as minor equally 2 microns.

Yet, D.E. filters are known to crave more maintenance, and not only because you have to add more D.Eastward. powder after backwashing, but mainly because there are just more parts inside the filter tank.

One of the best things you lot can do to maintain proper DE filtration is to open up the filter tank and make clean the filter grids. This is done during puddle winterization, or every 6 months of use, for sunbelt pools open up all year.

TYPES OF DE FILTERS

Hayward Perflex Nest Assembly, containing 120 Flex Tube 'Fingers' Today there are two types of DE filters in use, Vertical Grid filters, and Hayward'south Perflex filters which use a cylindrical 'Flex Tube', shown correct. Both vertical grids and Flex Tubes, aka 'Fingers', are covered in a mesh polyester fabric, with pores pocket-size enough to allow h2o to pass through, only not the DE pulverization.

HOW DE FILTERS OPERATE

Pentair / Hayward Curved Vertical DE Grid Assembly The fabric roofing the grids or tubes serves to agree the DE powder, which covers the fabric. As the water passes through the powder, the dirt is trapped in the powder's microscopic pores. The pulverization is the filter, not the grids.

Over fourth dimension, the DE pulverisation will trap so much dirt, oil and droppings that water will have a harder time passing through, which will heighten the filter tank pressure level and reduce the flow rate. Eventually it becomes necessary to flush out the muddied DE pulverization in a backwash procedure.

WHY A 'DEEP CLEANING' IS NECESSARY

Anthony Filter Grids Backwashing does not flush out all of the powder, sometimes merely half of information technology is actually removed. Calculation a full dose of DE powder later on can lead to bridging betwixt the grids, resulting in less effective filtration.

Opening up the tank to hose off all of the powder every half dozen months, is important to maintain filter performance. And for pools that winterize and drain the filter tank, assuasive the DE pulverisation to dry onto the grids creates clogging problems the following year.

Minerals and Oils besides build upwards within the filter fabric of a DE grid or Flex Tube, which backwashing does not remove effectively. Hosing clean will remove some (fifty-fifty if using the Mega Blaster DE Cleaning Tool), but for best results a chemical soaking is used to remove mineral scale and oily deposits.

CLEANING VERTICAL DE GRIDS

1. Open air bleeder and remove filter drain plug to drain water from the tank.
ii. With the proper wrench or socket, loosen the bolt and remove the clamp.
3. Loosen the lid and pull it directly off. A apartment tool may be needed to pry information technology off.
4. Spray grids with a hose, to remove about of the heavy DE powder.
5. Lift upwardly on sides of top manifold, with a slight twisting motion, to free the grids from the standpipe. Two people may be needed, to lift the grid associates out.
6. Place grids on a stable area, beingness careful non to allow the assembly fall over, which tin can crack the top manifold.
vii. Do not accept the grid assembly apart, just spray h2o fully in-between the grids, to completely clean grids on both sides.
8. Supercede grids carefully dorsum into tank, applying a small corporeality of lube to the standpipe o-ring, institute on Pentair and Hayward filters.

CLEANING PERFLEX FLEX TUBES

ane. Close off the pump, push bump handle downwardly slowly and upwards quickly, eight times.
ii. Open vent valve and remove filter bleed plug to drain water from the tank.
3. After draining completely, turn filter pump on for 5 seconds to flush tank.
4. Shut vent valve and drain plug. Plow on pump to fill tank. Repeat steps 1-3.
5. If non winterizing, restart pump to make full filter with water, adding new DE pulverization.

DE FILTER CHEMICAL CLEANING SOLUTIONS

Hosing off the filter grids, or performing the Perflex cleaning procedure as described above is suitable in most cases, nonetheless a chemical cleaning may be necessary from time to time to remove mineral scale and oily deposits.

Mineral Deposits: Primarily calcium calibration from pools with high levels of calcium hardness, or from improper water residue. Scale volition chop-chop clog the pores of DE grids and Flex-Tubes, causing short-cycles to occur.

Acid Magic Scale tin can exist removed past soaking the Flex Tube Nest Assembly or the DE Filigree Associates in a 20% solution of Water and Muriatic acid (5:1 ratio). Soak Flex Tubes in a large saucepan and DE Grids in a large (clean) trash can for several hours, and then hose off thoroughly.

Oil Deposits: A more than common problem than calcium build-upward, oil and grease can be a real trouble for DE filter grids and Flex Tubes. Suntan lotion, pilus products, cosmetics and wind blown oils, in addition to o-band lubricants and calorie-free oils found on plastic and vinyl products tin all clog your DE filter.

in-the-swim-de-filter-cleaner Oils tin can be removed by soaking filter grids in TSP and hot water, using 1/2 lb. per 5-gals of water. You lot can also utilize our DE Filter Cleaner or Natural Chemistry'south Filter Perfect chemic to spray or soak the DE Grids or DE 'Fingers'. For pools with continuous problems with oils, try Jack's Magic Filter Fiber as a replacement for DE pulverisation.

Stains: It's non uncommon to run into DE grids or fingers turn a yellowish color, or fifty-fifty a rust colour over fourth dimension. In nearly cases this will not affect the filtration besides much, simply some stains can also incorporate other particles, which can reduce the small pores of the DE filter fabric.

To remove stains on DE filter grids or Perflex Flex Tubes, I recommend using our Granular Filter Cleaner chemical, which is a combination of scale and stain fighters, and can restore the virtually-new color to DE grids and fingers, while increasing filter flow rates.

REPLACING DE FILTER GRIDS

If during your cleaning and servicing, you lot find several holes or the threads get-go to unravel or the grid material deteriorating, it may exist time to replace the filter grids, which is the bailiwick of this related mail service, DE Filter Grid Replacement.

For Perflex filters, you can buy the Flex Tubes individually or in 5-Packs in our parts department. You tin can as well purchase the consummate Flex Tube assembly, called the 'Filter Nest', or you may consider buying an unabridged new Perflex DE Filter.

INSPECTING DE FILTER GRIDS

To Audit your DE filter filigree assembly, look for:

Tears or rips in the fabric, peculiarly at the seams and the lesser eye.
Broken tabs on the tiptop, where the grid inserts into the manifold.
Cracks in the manifold (don't let it fall over!)
Missing or damaged air bleeder screen or sock on the manifold.
Loose associates; missing through wing nuts on thru-bolts.
Missing or damaged standpipe o-ring; where the manifold fits on.
Mis-spaced or mis-aligned grids.

An annual inspection and cleaning should go on your DE filter running in tip-top shape. But don't wait if your filter starts acting funny – you can do this anytime!
