Change The Sand In Above Ground Pool Sand Filters
(Brampton Ontario Canada)
We have a Jacuzzi Laser 192 sand filter for an above ground pool.
When & how often should the sand be replace & could I do it myself?
Thanks for the question Dave
With normal use and good maintenance, pool sand will last anywhere between 5 - 10 years. If you allow too much debris in the system or let it get gunked up with oils and grease, it may be sooner. You can change the sand, but there are some things to take into consideration, mainly checking the laterals. If they're broken or cracked they need to be replaced. This is true for the standpipe as well.

Be sure you're using the correct size sand, not sand box sand. I believe your Laser 192 series calls for 0.44mm sand and about 200lbs. If you don't have the owner's manual, this is a good link:
If you go on the link, you'll see on page 2 the "Sand Filter System Dimensions". It gives the sand level of 12.5" (F). I would encourage you to call the manufacturer for what is known as "freeboard". This is the measurement from the top of the sand to the top of the filter.
This way you'll have the correct amount of sand and the measurement. When you put new sand in the filter, some will be lost due to backwashing and settling. You'll probably have some sand going back into the pool through the returns. This will decrease over time.
You may need to top off the sand later on. This is why knowing the measurement of the freeboard is important. Hope this helps and have a fun and safe swimming season.
