How To Change The Sand In Your Pool Filter

clock May 4, 2017 07:00 by author medallionpools |

After a few years of normal operation your pool filter sand gets full of particles and debris that will cause your chemicals to not work as well as they normally should. Changing your sand is a simple process that should be done at least every 3-5 years to make sure your pool operates at 100%. Here are the quick and easy steps to replacing your sand filter. Please note that these are generic directions for a unit with a removable, top mount valve. For the correct procedure for your filter, refer to the owners manual that came with your filter.

1. Turn off the pump, unscrew the drain plug on the bottom of the sand tank, and take off the Multi-Port valve.

2. Take a wet/dry shop vacuum and suck out all the old water and sand.

3. Once all the sand is removed take a water hose and spray out any remaining debris that is left in the tank (Be cautious to not break the plastic laterals that are in the bottom of your tank when vacuuming)

4. Put back on the drain cap for the sand filter.

5. Fill your tank at least half way up with water (this helps the sand settle down easily without breaking the plastic laterals)

6. The type of sand that you add to the filter will be #20 silica sand which is specifically produced for filter media. This sand is between 40-50mm in diameter and is available from most swimming pool supply stores. Do not substitute other types of sand or you will almost certainly have problems with your filter and potentially damage the pool also.

7. The amount of sand that you add to the filter will depend on the size of filter that you have. You must be certain to find accurate information about how much sand to use in your filter. Over filling or underselling the filter will at least cause the filter to not function properly, and at worst cause damage to the filter. Filter sand sizes range typically from 100 or 150 lbs all the way up to 600lbs or more for large pools.

8. Be sure not to get any sand into the sandpipe which will be wide open. It is difficult to get the sand actually into the filter without getting it in the sandpipe so you may like to tape up the standpipe opening to prevent this spilled sand from making it back to the pool through the return lines. Also, be sure that the sandpipe is aligned in the center of the tank during the process of adding the sand. Failure to do so will cause you to have problems putting the multi-port valve back on the tank.

9. Gently pour the sand into the filter. Failure to fill the tank at lease half full of water and/or dumping the sand in too roughly can break the laterals in the bottom of the tank.

10. Once the sand tank is filled with the required amount of sand, you can put the MPV back on. Make sure the MPV is tight and secure (do not over tighten.)

11. Once back together the first thing you need to do is give the filter a thorough backwash. You should start this process by over filling the pool and then backwashing for as much as 3 to 5 minutes, followed by a 60 second rinse cycle before setting to "filter".

If you have any questions about the process of changing your sand, please make sure to contact your pool professional.



When Should You Change The Sand In Your Sand Filter

Have you noticed the look of your pool water is not as clear as it used to be? Have you noticed no matter how much water clarifier you put into your pool, the water is still cloudy? Have you noticed the sanitizer level is not as stable as it used to be? Do you notice dirt or debris blowing back into your pool thru the return fitting?

If you answered yes to any of these questions, when was the last time you either cleaned your sand filter or changed your sand? You should use filter cleaner each season and clean your sand. For example; if your sink becomes clogged at home, you usually use a drain cleaner to remove the problem. Same principle with a sand filter but you would use filter cleaner.

It is not a set rule when you should change your sand but a good guideline is usually every 3-5 years if you have been using a filter cleaner every season. If you do not use a filter cleaner you will need to change it more often. This time line can change based on what type chemicals you use, amount of activity in your pool, and how often you keep the filter running. Suntan lotion and waste from your body both play a part in decreasing the effectiveness of your sand filter.

When you do change your sand in the filter, it is a good time to also check the laterals that you will find in the bottom of your filter below the sand. If they are broken or cracked, be sure to replace them. Any that are broken could cause sand to blow back into your pool. You should cover these laterals with water first before adding any sand. The heavy sand could cause some damage to them.



Planning Information For Opening Your Swimming Pool

We realize it is still too early to remove the cover from the pool and start using it, but it is never too early to plan. If you have a sand filter, when was the last time you either changed your sand or cleaned the sand? As you go through a swimming pool season, suntan lotion, oils from your body, peeling skin, etc. all go into your filter and could affect the operation of the sand filter.

The sand should be cleaned at least once a year and how often you change the sand will depend on how active you are in using your pool, how many people use it daily and how well you keep the pool chemically balanced. You should try to change the sand at least once every three to five years depending on pool usage. If you have not changed the sand within five years, a good time to do it would be before you remove the pool cover.

Check the o-rings on the pump drain plugs. When was the last time you changed them? If they are worn, this will cause air to get into the circulation system and you might have a hard time priming the pump or getting a good flow of water into the pool. You should replace them each season. Also check the drain plug on your filter to see if it has an o-ring.

Your sand filter has a multi-port value. Is the handle hard to turn? If it is, you might be having some problems with your spoke gasket. Fix it now while you still have plenty of time. When you turn the multi-port value handle, does it loosely fit back into one of the listed functions? If so, you should replace the spring. Make opening your pool a little bit easier by addressing these items soon.
