How to Build a Pool Sand Filter How to Build a Pool Sand Filter
Making your own pool sand filter will save a lot of money; it's easier than you think. By filtering the water through a sand filter first, you've cleaned the water of impurities, so that when it goes through the regular paper filter, it's already clean. Dirt will be trapped by the sand, saving you the trouble and expense of replacing the paper filter. The sand, on the other hand, will last for years. You must keep a watchful eye on the sand, so that you will know when it needs cleaning.
Cleaning your sand filter is easy. All you have to do, is to add water to the garbage can, then stir; dump out the water, as dirt has separated and is on top of the water. Do this a few times, until the sand is clean.
Step 1 - Make Holes in the Garbage Can
Using a medium plastic garbage can, get a clear garbage can, if you are able to; it's helpful to be able to see when the sand needs to be cleaned.
Start by making two holes in the can; one hole in the middle of the lid, the other hole should be made on the side near the bottom, as close as you can get. The holes need to be identical in size to the tubing for the pump.
Step 2 - Attaching Tubing
Attach the tubing to the hole in the lid using the caulk; this tube will lead to the pool. Attach the tubing to the bottom of the can with caulk; this tube will lead to the pump and filter.
Step 3 - Adding Sand
Make certain that you have pool filter sand, other sand will not work. Pool sand is available at pool stores and some hardware stores; one bag should be enough. When adding the sand, you don't want the sand to leave out of the tube on the bottom, secure the metal strainer, with the caulk, to the hole in the bottom to block the tubing. When filling the can with sand, fill it nearly to the top, leaving enough space for water to be able to evenly accumulate on the top of the sand.
Water is going to travel from the pool onto the top of the sand, filter through the sand and, in time, depart out the tubing on the bottom. You won't have any difficulty, if your pump is going at a faster rate than the rate of the water. Make certain that the lid is secure; whatever you use to secure the lid, be certain that the lid is still removable so that you can clean the sand when needed.
Step 4 - Turn on Pump
Now that everything is connected, you can turn the pump on.
