After some time, you'll notice that the sand filtration system isn't working optimally as it used to do. Also, the water has gotten cloudy and dirty and doesn't improve even after sanitize. Perhaps it's time to clean or replace the sand within. Worry not! Today, we'll guide you on the sand replacement process.
Sit back, and let us take you through.
What is Pool Filter Sand?
Algae, bacteria, and dead bugs are things that hang around, making pool water dirty and cloudy. They bring dirtiness to the water. Eventually, they will get swimmers sick and uncomfortable. The filter media is a vital thing that grabs such contaminants. That media is the sand.
Sand is magnificent filtration media. Apart from that, sand is used in numerous water safety applications like septic systems, wastewater treatment, and also for drinking water.
To a starter, the sand looks relatively much the same, and you might believe all sand is made equal. Nevertheless, the case is different. Don't be attracted by that bag of sand in the garage. This cheap stuff might harm your filtration system. It's advisable to use one of the following types of sand during the replacement process.
If you're considering filter sand with less environmental impact, then glass sand is a standout. It's an effective media. It's typically made from 100 percent recycled glass. Not to mention, the sand is not only smooth and polished to touch. The unique thing is that glass sand can capture particles of two microns.
Practically, glass grains come in different sizes. Hence it minimizes channeling that takes place when water cuts a straight path through the glass sand. Besides, glass sand features a negative charge. It, therefore, flourishes at capturing manganese and iron particles. This comes to the advantage if your pool is characterized by hard water sources.
Most pool owners use silica as their preferred pool filter sand. Silica is mined from ground quartz that creates very sharp grains. With jagged edges, these grains are outstanding for trapping particles from passing pool water. Remember that silica isn't manufactured but mined.
Zeolite comes from volcanic rock minerals known as zeolites. Silica boasts greater surface area compared to standard filter sand. Featuring a sponge-like honeycomb shape, the sand is overkill.
Chemically, zeolite traps chloramine, which is a choline byproduct that usually stings your eyes when swimming via molecular sieving. Zeolite sand traps chloramines particles indefinitely.
If you fill that your pool needs a frequent shock, zeolite sand help to control chloramines, and at the same time, you don't have to use many pol chemical additives.
Step to Changing The Sand
After concluding that your filter is the main problem to your cloudy water, kick-off to sand changing. You'll like the process and how easy it is.
What you need:
- Garden hose
- Pool filter sand
- Rubber plug or duct tape
- Utility knife
- Backwash hose
# Switch Off the Pump & Drain the Filter
Switch off both the filter and pump. Ensure you set the timer in a way that it won't turn on soon. This will hinder the pump from kicking on when everything is disconnected. Note that your pump can kick on and easily burn out if it's dry.
Drain out the water by removing the drain plug at the bottom of the tank. Draining the tank may take some minutes, so the best idea is to do this step in the morning. Then come later in the day to finish the job.
# Remove the Multiport Valve
Keenly remove the pipes or hoses that are connected directly to the multiport valve. At times, you've to cut the hose, especially if the tube is plumbed with PVC. If you can't manage to do this, seek assistance from a pro.
Once the pipes are cut, you can install union fillings. With this, it will be easier to unscrew the hose fitting next time round. You won't require a hacksaw.
Using the screwdriver, remove the collar or clamp, securing the valve. Gently twist and pull up the pipe on the multiport and remove it.
# Cover the Standpipe
You'll notice that inside the tank there's an open pipe where you've just removed the valve. Now cover it well with duct tape to keep away sand from getting inside. Failure to this, the sand will be flushed into your pool once your turn on the pump again.
# Remove the Sand
Using the Shop-Vac, suck out the old sand. You could use a plastic cup if you didn't purchase a Shop-Vac. Scoop all the old sand. You can ask your friends to help you with Shop-Vac. Borrow, or just buy one. Shop-Vac is essential and comes in hand in other jobs.
# Rinse Out Both Tank and Laterals
Now that most sand is gone, you'll have a wider view of arms that branch out of standpipe. With you, garden hose, rinse, and remaining kilograms of sand. Use the flashlight to inspect the laterals and standpipe for damage amazingly. Remember that any crack can let the sand into the pool. So, before adding fresh sand, repair the necessary parts.
# Fill Your Tank Halfway with Water
Change the drain plug. Let the hose remain down into the filter tank while you continue filling. Center the laterals and standpipe as you hold them while the tank fills halfway. You can add some water before the sand replacement process to protect the laterals from falling due to the weight of the sands.
# Add Your New Sand
It's time to wear your mask. It will protect you from breathing in dust. Inspect the standpipe and add the duct pipe if necessary. Now hold the bag as you extend it over the tank's opening. Slice it with your utility knife. Take your moment and watch the sand as it drains into the filter tank.
Add a 50 kg bag of sand at a time. Let it spill inside the tank and not everywhere. So you must perform it slowly. Only use filter sand. Anything else might damage your filter. To increase the efficiency of filter sand, add a few liters of D.E powder.
# Filter Your Tank & Reassemble the Connections
Assuming all the sand has spilled inside the tank, fill your tank with water. Moreover, replace the collar, multiport valve, hoses, and pipes. Ensure all the fittings and connections are excellent, snag, and secure.
# Backwash & Rinse the Filter
When everything is decent, attach the backwash pipe or hose, and turn the valve to backwash (multiport valve)—the turn on the pump. Backwash the filer for 2 to 10 minutes and check whether the filter's glass is clear. This step will wipe out extra debris and sand dust from the new filter sand.
Shut your pump off, carefully set the valve to rinse, and eventually turn your pump back on. It's a multiport. Rinse your filter for at least one minute.
# Run the Filter
Your last step should be 'run the filer.' Shut your pump off and turn the valve to enhance filtering. Turn on the pump. Now check out the pressure gauge. Ensure its normal running pressure of the filter. Note it down somewhere.
Keep checking the gauge to allow normal and effective pool maintenance. If the pressure is around 10 psi or above normal, just backwash the filter. Use the pressure gauge as the backwash indicator. It will curb the over-backwashing. It will also guide you in removing the debris and dirt to guarantee the proper functioning of the filter.
