Your Swimming Pool Cartridge Filter will not clear algae from the pool

The three filter types will clear up algae, provided it is not in a live state. Consult http://www.1800 Pools.com for the proper chemicals to help rid the algae. Most cartridge filter problems are caused by dirty, clogged or abused elements. Either clean the elements, or replace if torn or damaged.

Your Swimming Pool 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, then vacuum. The presence of alum or flocking agents will clog the filter. Vacuum so as to bypass the filter. Do not use flocking agents with DE filters.

Your Swimming Pool DE filter 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.

Your Swimming Pool DE filter is running at high pressure

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 your filter.
Refer to your Owner’s Guide for further instructions or consult your pool dealer for service.
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 Manuals for instructions.

Your Swimming Pool DE filter short cycles even after I backwash

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 operating 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. Refer to your Owner’s Guide for the amount of DE your filter requires. Biguanide based sanitizers (i.e. Baquacil, SoftSwim) can cause short cycling.

Your Swimming Pool Filter is noisy

An oversized pump may cause noise in your filter valve due to excessive flow. To test, hold your hand partially in front of any returns at the pool wall. If the noise subsides, this will confirm that the problem is excessive flow. It can be remedied by installing smaller eyeball fittings in the return(s), changing the pump impeller size in the pump, or change to a 2-inch control valve.

Your Swimming Pool Flow Valve leaks to Waste

The valve seat gasket inside the valve has become worn or loose. You may choose to do this yourself or contact your local pool dealer for service. How do you replace the gasket? You will need a new gasket, obtained from your local dealer, some Krazy Glue, and a sharp 1/8-inch wide flat bladed screwdriver.

NOTE: Mark the top and bottom of the valve with a marking pen. It’s very important that you do not change the location of the cover when re-assembling. Remove the cover, usually six screws. Using the screwdriver, scrape out every last part of the gasket and cement, in order to get back to a clean flat surface. Put a fair amount of crazy glue on the flat side of the gasket. Place the gasket, flat side down, back into place let dry for one hour minimum.

Your Swimming Pool Sand Filter is running at high pressures

Follow the backwashing instructions in your Owner’s Manual. The sand bed may be clogged with mineral deposits that will not backwash away. Some calcium based chlorines and other alternative sanitizers will build up in your sand bed, and will require more frequent backwashing and changing of the sand.
Before you replace all the sand in your filter, try removing approximately 1″ of the top layer of the sand, replace with the exact amount of sand you removed.
Normal life span of the sand is about 4 – 5 years.

You may have to clean your filter system with a special filter cleaner, check with your pool dealer for proper procedures.

Check to see if there is a closed or partially closed valve along your return piping, open the valve.
Your pump may be too small to provide sufficient flow for proper backwashing. Your filter will function, but a lower design flow rate will cause your system to backwash improperly. Check the output of the pump to be sure that it equals your filter’s design flow rate. Replace the pump if it is too small.

Choosing a Swimming Pool Filter – The Types of Filters for a Swim Pool

Sand, Cartridge, or Diatomaceous Earth Swimming Pool Filter Systems
There is a lot of confusion about various filters, and many different opinions. Here are a few facts to consider. The first is that a pool can be properly maintained with any of the filter systems available: Sand, Cartridge, or Diatomaceous Earth (DE). Here is a brief description of each type:
* Sand The bullet proof filter
Water is pushed through a bed of filter sand and removed through a set of lateral tubes at the bottom. The filter area of a sand filter is equal to the area of the filter itself. For example, a 24 filter will have 3.14 sqft of filter area. Only the top 1 of sand is actually used to filter the water. The principle behind this filter is that water is pushed through the filter sand, somewhat like an espresso machine. Dirty water goes in the top and clean water exits out the bottom. As the filter sand becomes plugged with debris from the pool, the pressure increases on the filter and the water flow drops. In order to clean the filter, you just run it in reverse and dump the waste water; this is referred to as backwashing the filter. Once the filter is backwashed, you move to the rinse mode and that repacks the sand and then back to filter. This has to be done manually every few weeks. From a hydraulics standpoint, a backwash valve is typically the most inefficient piece of equipment you can add to a swimming pool system. Should the sand ever become really dirty, it is easily and inexpensively replaced. In terms of particle size filtered out, sand is the lease effective method it can allow smaller particles to pass back into the pool.

* Cartridge The economic low maintenance filter.
This one is easy to understand. Water passes though a filter material and the filter captures the debris. This is just like the water filters used under your sink. Cartridges have much more available area to filter than sand. Most start at 100 sqft and the majority of the cartridge filters sold are larger than 300 sqft. So they dont clog up as quickly and therefore you touch them less frequently. There are two types of cartridge filters in general. In the first case, there are filters elements that are inexpensive to replace and as such, they dont tend to last as long. Then there are other filters that have very expensive elements and these last 5 or more years. In both cases, cartridge filters are designed to run at lower pressure than sand. This puts less back-pressure on the pump and hence you get more flow and turnover for an equivalent pump size. Generally these filters have to be cleaned once or twice a season by simply hosing them off, so you dont touch them as often. In terms of particle size filtered out, cartridge is somewhere between sand and DE.

* DE The water polisher.
Diatomaceous earth is mined and is the fossilized exoskeletons of tiny diatoms. They are used to coat grids in the filter housing and act as tiny sieves to remove debris. They are very small and as such can filter out particles as small as 5 microns. Diatom filter area are sized between sand and cartridge around 60-70 sqft are most common. Once the filter pressure rises, the filter is backwashed just like a sand filter and then recharged with more DE powder. Typically it is poured in a slurry into the skimmer and it then coats the filter grids. DE filters run at higher pressures than cartridge filters and as such can lead to some inefficiency and flow loss.

In Ground swimming pools had initiated the trend of swimming in many private places. They are long and located in the backyard. Best way to keep them swanky and in healthy condition is with the proper cleaning devices.

The two major types of cleaners are manual and automatic (robotic). The automatic are popular compared to manual ones. The manual cleaners require more attention because of their limitations. The robotic or automatic cleaners absorb dirt from the water quickly and independently. Aquabot Standard Robotic Cleaner and Aquabot Turbo Remote Control are readily available. There is a classification for in-ground devices- cleaners with suction technology and those with the unique pressure technology. The ones which have suction side technology, collects all dirt from the bottom areas and diverts along with the water moving through the skimmer. The dirt is gathered with the help of the filter system. Robotic cleaners holding pressure side technology utilize a pump separately to operate and provide the dirty water for the cleaner head. This water builds vacuum affects that will take out debris and dirt. Polaris Vac-Sweep and Pentair Letro Legends pool cleaners are examples of pressure side technology machines. Both of them are in demand depending on the usage of the by owners. Manual swimming devices require lot of high voltage electricity whereas automatic cleaning equipment uses low voltage to avoid electrical shocks. Some cleaning machines come with computer chips and these are the expensive robotic ones. Only dirt free the water invites the intrepid swimmer!
