How Do I Clean A DE Filter?

DEV60_vpready_filter_1

There are three different types of filters for your swimming pool. Are you familiar with what type of filter your swimming pool uses? The three different types of filters are diatomaceous earth (DE), sand and cartridge. As for types of filters and swimming pool products, we always recommend Jandy! In this blog post, we are going to highlight the pros and cons of a DE Filter, the benefits of them and how to clean them. In regards to residential and commercial swimming pools, sand filters seem to be the most common filter you will find in a backyard due to ease of use. However, DE Filters are pretty close second. If you talk to people in the industry, most people seem to think that DE Filters are more challenging to use but if you get used to them, they work the best for most swimming pools. This is because they filter down to the smallest micron and have the ability to keep pools extremely clear and clean.

Pros of DE Filters –

  • Filters down to 3 microns which are the smallest amount of the filters
  • Filters the largest surface area and keeps the pool the cleanest out of all of them
  • Best for pools with lots of vegetation/plant life in the backyard. If you have lots of trees, bushes, and plants that blow leaves into the pool this filter is the only choice for you.
  • Will clear up a green pool the fastest (some pool companies will even wheel these filters out to your pool to help clear it up faster)

Cons

  • Requires the most amount of maintenance especially after backwashing
  • Must always be aware of pressures as backwashing should occur at set limit to prevent pool from getting cloudy

For the most part, DE Filters are extremely self-sufficient but do require some work when it is time to backwash. Backwashing can be described as cleaning your filter after it’s collected debris and dirt from your swimming pool. It works by sending pool water in the opposite direction through your filter and out the waste or drains port. It is pretty easy to do and we explain that next……

How To Backwash Your DE Filter

  1. Turn off your filter and turn your valve to the backwash position. If you have a top mounted handle, place it in the backwash position.
  2. Turn your filter system back on and let it run for approximately two minutes or until the water is clear and free of debris
  3. Turn the system back off and place backwash valve back in normal filter position
  4. Run the filter for a minute or so and repeat steps 1-3 for about 30-60 seconds or again until the water is clear
  5. Turn your system back on and make sure to add DE powder to the skimmer as soon as possible as filter grids must be coated to prevent other issues.

How Much DE To Add After Backwashing

First and foremost, you will need to determine the square footage of your filter which you can typically find on the label located on the filter. The following is a breakdown of how much DE to add to the skimmer after backwashing:

36 sq ft. —–> 4.5 pounds (roughly 4.5 scoops)

48 sq ft. —–> 6 pounds (roughly 6 scoops)

60 sq ft. —–> 7.5 pounds (roughly 7.5 scoops)

The gauge on the top of the filter will make you aware of when you need to backwash. Typically, you can also check the manual to let you know at what PSI they should be back washed. Please keep in mind you will monitor this regularly as backwashing should occur as soon as possible when the pressure reaches its maximum. Also, if you own a DE Filter please plan on taking the filter apart at least once a year to completely hose down the filter grids and clean the inside of the filter to keep it functioning properly. If you should have any questions on how to operate a DE Filter or if you’re in the need of a filter clean, contact us today and if you are looking to make a switch in filters, Weber Pools can help you with that as well.

What Is The Best Filter For My Swimming Pool?

As a swimming pool owner, you have three different choices when it comes to filters for your swimming pool. Each of them has their differences and benefits depending on what you are looking for and we want this blog post to be informative on the differences of each. We will be discussing the types of filters, what makes them unique, when they should be cleaned as well as price points for each. As we have stated in the past, Weber Pools will always choose Jandy first. As an authorized dealer we like Jandy for their price points, reliability, warranty and of course functionality. As for the filters for your swimming pool, you can choose sand, cartridge or diatomaceous earth (DE). Each one of these filters can be further broken down into the following categories to help us decide on which best fits your needs:

  • Type of liner
  • How much vegetation you have around your swimming pool
  • Surface area of the pool
  • Water conservation factors
  • Ease of use
Jandy Sand Filter

Jandy Sand Filter

Sand Filter  

Pros

  • Easiest filter to use
  • The most common filter you will find for swimming pools
  • Filters down to 20 microns
  • Easy to backwash when pressure rises to set backwash number

Cons

  • Requires replacements of sand every 5-8 years or when laterals break
  • Not recommended for pebble tec pools or pools with lots of vegetation due to high micron number
  • Can take much longer to clean up a green pool with this type of filter
  • Can be the hardest filter to work with when parts break because you usually will need to vacuum out the sand if it’s on the inside.
Jandy Cartridge Filter

Jandy Cartridge Filter

Cartridge Filter

Pros

  • Simple and easy to maintain
  • Filters down to 10 microns
  • Since there is no backwashing it is the best filter if you are looking for water conservation.
  • Filters better in large surface area pools

Cons

  • More expensive filter out of the three
  • Cartridge replacement can be more expensive

 

Jandy DE Filter

Jandy DE Filter

D.E. Filter

Pros

  • Filters down to 3 microns. This will keep your pool the cleanest
  • Filters the largest surface area and keeps the pool the cleanest
  • Best for pools with lots of vegetation in the backyard
  • If you happen to get a green pool, this filter will clean it up the quickest

Cons

  • Requires the most amount of maintenance especially after backwashing

The key to picking out which type of filter for your swimming pool is ultimately dependent on you but the above factors should help you make a decision. Most importantly, if your swimming pool is surrounded by a lot of trees, plants, soil and other types of vegetation, the clearest cut choice for you to keep your pool the cleanest is going to be a D.E. filter. Other than that, if you’re in an area where there are drought conditions we would recommend a cartridge filter because there is no backwashing and it does a great job of keeping your swimming pool clean. When it comes to a sand filter, all that is necessary is a backwash but always be on the lookout for sand in your pool. When that happens, you might have a cracked lateral, which is the main filtration mechanism in a sand filter. At this point, a sand change will be necessary. As for cartridge filters, when the pressure rises to the maximum, they will need to be hosed down and cleaned (typically quarterly). Make sure to open up the pleats of the filter to thoroughly clean them. Finally, a D.E. filter should be taken apart at a minimum of one time a year. You will need to hose down the grids to get the excess D.E. off of them and then recharge the filter when you put it back together. Please note, that if you see D.E. blowing back into the pool, that’s a sign there’s a tear in the grid and it will need to be replaced.

At Weber Pools, we are very familiar with each type of filter and can keep track of backwashing, cleaning and replacing if necessary. If you should have any questions in regards to filters, contact us today!

What Type Of Filter Is Best For My Swimming Pool?

If it’s time to re-evaluate the filtration system in your swimming pool, there are many different factors that go into what makes the best filter for your swimming pool. The most common filter that we see and easiest to install is a sand filter but we want to discuss a variety of different factors so you can make a wise decision and get the best filtration for your pool! When making that decision the following factors should go into that decision:

  • Type of liner
  • The amount of vegetation around your swimming pool
  • The surface area of the pool
  • Ease of use
  • Water conservation factors

With that said, we hope this blog post gives you some insight on the best type of filter for your pool, when they should be cleaned/backwashed and what to look for when they need to be cleaned or replaced. Currently, there are three different types of filters; cartridge, sand and diatomaceous earth (D.E.) and we will be evaluating each to help you understand what makes them unique. First, we will highlight the pros and cons of each:

Jandy Cartridge Filter

Jandy Cartridge Filter

Cartridge Filter:

Pros

  • Simple to maintain
  • Filters down to 10 microns
  • Since there’s no backwashing, it uses the least amount of water and is the best during drought conditions.

Cons

  • Most expensive out of all the filters to purchase
  • The cartridge filters can be pretty expensive
Jandy Sand Filter

Jandy Sand Filter

Sand Filter:

Pros

  • Easiest to use
  • Most common filter for swimming pools and works with most. Most common commercial swimming pool filter as well.
  • Filters down to 20 microns
  • Easy to backwash when pressure rises to set backwash number on guage

Cons

  • Requires replacements of sand every 5-8 years or when a lateral breaks (this can be a lengthy process as it takes awhile to vacuum out the sand).
  • Not recommended for pebble tec pools or pools with lots of vegetation due to high micron number. The pebbles from the pool can get stuck in the sand or laterals
  • If you have a green pool, it can take a very long time with this type of filter to clear up
Jandy DE Filter

Jandy DE Filter

D.E. Filter

Pros

  • Filters down to the lowest of microns which is 3
  • Filters the largest surface area and keeps the pool the most clean
  • Best for pools in backyards with lots of vegetation

Cons:

  • After backwashing, it does require the most work

The above factors are key to making a decision on what type of filter you should buy. Most importantly, a D.E. filter is the best filter if your pool is surrounded by lots of vegetation.  Keep in mind all of these filters have pressure gauges with recommended numbers as to when they need to be backwashed or cleaned. With a sand filter, all that is necessary is a backwash but always be on the lookout for sand in your pool. When that happens, you might have a cracked lateral, which is the main filtration mechanism in a sand filter. At this point, a sand change will be necessary. As for cartridge filters, when the pressure rises to the maximum, they will need to be hosed down and cleaned (2-4 times a year). Finally, a D.E. filter should be taken a part at a minimum of one time a year. You will need to hose down the grids to get the excess D.E. off of them and then recharge the filter when you put it back together. Please note, that if you see D.E. blowing back into the pool there’s a pretty good chance there’s a tear in the grid and it will need to be replaced. With any of these filters, Weber Pools highly recommends Jandy Filters for their reliability, price point and warranty.
