If you have a pool, you need a low-maintenance, inexpensive, and efficient way of pool filtering. Hayward S200 does its job very well. It is wildly popular partly because it rarely clogs. But to ensure its smooth performance, you need to replace the sand every 5-7 years. In this post, we are going to show you how to change sand in Hayward S200 pool filter.
Why You Need to Change the Pool Filter Sand
To understand the necessity of changing sand in your pool filter, first of all, you have to understand what the pool pump does. It basically pulls water and sends it to the filter. In the filter, the water passes through the sand and the sand traps the contaminants.
If this procedure continues for multiple years, the sand in the filter loses its effectiveness to some extent. It happens because the prickly, rough surface of the sand becomes smooth over the years. And smooth sand can not filter water as effectively as prickly sand. In order to maintain the effectiveness of the filter, you have to change the sand.
When to Change It
Besides learning how to change sand in Hayward S200 pool filter, you have to know when to do it. The lifespan of pool filter sand is usually 3 to 5 years. And as time passes, contaminants get trapped in the sand. In the first year or so, the filtering ability of the sand actually increases. Then contaminants build-up and the sand gradually loses its filtering ability. For good results, use HTH pool filter sand.
Due to the extra gunk in the sand, the filter can also get clogged. The sand becomes incapable of trapping contaminants, due to the weathering. As a result, the quality of your pool water suffers. You have to change the sand in your pool filter every 3 to 5 years.
How to Change Sand in Hayward S200 Pool Filter
If you are sure that your pool water looks cloudy because of the poor filter, you should change the sand as soon as possible. The procedure is very easy. Here are a few things you will need to do it:
- Garden hose
- Duct tape
- Pool filter sand
- Utility knife
- Diatomaceous earth
- Backwash hose
1. Switch off the pump and empty the filter
First, you have to switch off the pump. Make sure the timer is not on, because you do not want to turn on the pump on soon. When everything is disconnected, the pump must be turned off. Remember, the pump may burn if it kicks on.
Pay attention to the filter tank and disconnect the drain plug. The water will drain out. You might take some time to empty the filter tank. So, it is a good idea to do it early in the day.
2. Take off the multiport valve
The multiport valve is connected to pipes and hoses, and you have to remove them. You may need to cut the pipe if it is a PVC pipe. This part of the process may sound a bit intimidating, but this is how to change sand in Hayward S200 pool filter. If you think you will not be able to do this part, do not hesitate to hire a professional.
Once you have cut the pipes, it is time to install union fittings. The process involves unscrewing the pipe fitting. You do not need to use a hacksaw to do it. To remove the collar or clamp, use a screwdriver. Then remove the multiport valve by twisting it gently.
Once you have removed the valve, you will find an open pipe inside the tank. Use duct tape to cover the pipe. Sand will not get inside if the pipe is covered.
3. Remove the sand
Then suck out the old sand. Use a Shop-Vac to do it. However, you can do it without a Shop-Vac. You can use just a plastic cup to scoop the sand out. But remember, this is not the best way to do it, because it may take forever.
Borrowing a Shop-Vac is probably a good idea. Investing in one does not hurt either, because you can use it for many other purposes.
4. Rinse out the remaining sand
Once you have removed the sand, there is very little work to be done. Rinse out the remaining sand with a garden hose. Inspect the sand with a flashlight. If you find cracks, repair them immediately. Do not ignore this part, because it is annoying to find sand in a swimming pool.
5. Fill 50% of the tank with water
Find the drain plug and replace it. Start filling the tank by putting it into the hole. Make sure the laterals and standpipe are centered. Hold the standpipe in place. Before you replace the sand, you can add some water. Thus the laterals will be protected from the falling sand.
6. Add new sand
When you do so, make sure you do not end up breathing in dust. Wear your mask. If necessary, you can add more duct tape. Use a utility knife to extend the opening of the sand tank. Do not hurry. Take your time to fill the sand tank with new sand.
Make sure the sand does not spill. Use up all the sand in your bag. Do not use anything other than pool filter sand. Other types of sand can ruin the filter.
7. Reassemble the connections
If you want to learn how to change sand in Hayward S200 pool filter, you must learn how to disassemble and reassemble the connections of the filter. However, if you can disassemble the connections, chances are that you will be able to reassemble them easily.
Once you have poured all the sand, fill the tank with water. Replace the collar, hoses, pipes, and multiport valve. Secure all the fittings.
8. Rinse the filter
Then attaché the hose and turn on the valve. Turn the pump on. The filter should be back washed for a couple of minutes. Make sure the sight glass of the filter is clear. The procedure will remove the sand dust from the sand. The filter should be rinsed properly.
9. Run the filter
Then you have to restart the pump. Just turn it off and then turn it back on. Now, pay attention to the pressure gauge. This is the normal running pressure of your filter. It is good to write it down so that you do not have to remember it.
When performing pool maintenance, check the gauge. Backwash the pressure filters if the pressure goes beyond normal. A backwash indicator can be used as a pressure gauge. If you do it, you will not end up over-backwashing.
The hardest part of the process is to choose the right type of sand. In this regard, making the wrong choice is absolutely unacceptable. Before you choose a particular type of pool filter sand, make sure it is the right type.
As you have noticed, the process of changing sand is pretty easy. Now you know how to change sand in Hayward S200 pool filter, and hopefully, you will do it properly.
