Nothing is impossible and nobody is perfect! One may dream of inventing the best thing ever but certain small errors are inevitable. Design of diatomaceous earth filters has a similar story. No matter how many points support the endurance and efficiency of these filters, there are some troubles that cannot be avoided. The good news however, is that one can deal with these troubles and continue using the filter.

The problems with DE filter do not paint a bad picture of the same – they simply imply that these filters need a little more care and attention when compared to that for sand filters and cartridge filters. Furthermore, most of these troubles arise due to the intricate design of these filters that comprises of almost twice the number of components as that in other types of pool filters.

The complicated build of DE filters accounts for the complexity in operating these. For instance, the powder cake on DE filter grids needs to be maintained consistently. Also, the grids need to be flushed out on an annual basis.

Some of the problems have been explained below:

Water Leakage:

Water Leakage:

Water leaks are a major problem in DE filters, occurring at a few specific parts such as -

  • Clamp Band: Leakage in this part mostly happens because of a dirty o-ring. It is thus better to get started with a clean o-ring. Also, make sure that the clamp band is centered between the two halves of the tank. Use a socket wrench to tighten the clamp until both springs come in contact with each other. In case of any damage to the clamp band, switch off the pump and adjust the position of the band.
  • Drain Plug: Leakage from this part can be avoided by wrapping it with Teflon tape. One can also use a lube to seal the drain plug in case of a leakage.

Leakage of DE Powder:

Leakage of DE Powder

Like water, DE powder can sometimes leak from the filter. This leakage is common in the following parts:

  • Manifold: A filter running at a high pressure for a long time can create a hammer effect in the water, thus causing damage to the manifold. This damage can be prevented by timely filter replacement.
  • Filter grids: With continuous usage, DE filter grids tend to develop holes – sometimes the stitching on these grids starts to unravel, allowing the DE powder to pass through. It is thus better to replace damaged grids as soon as possible.

As far as the choice of new filter grids is concerned, you will find multiple options on online stores. A large number of pool owners today prefer Hayward filter grids as these are highly durable.
