The sand filter in a salt water pool helps to maintain high levels of hygiene in the water and makes the water more conducive for use. Read on to find out how to use a sand filter.

Step 1 – Safety Precautions

Before you start installing the sand filter in a salt water pool, make sure the electric supply is cut off. Switch the circuit breaker off or pull the electric chord out.

Step 2 – Connecting the Filter and Pump

Connect the pool pump and the filter with the help of a hose. Attach the hose to the pump valve and the other end to the filter's inlet valve.

Step 3 – Holding in Place

The hose clamp will help hold the connection established in Step 2 in place. With the help of a screwdriver, tighten the clamps.

Step 4 – Connecting the Filter and Return Jet

In this step, you need to connect the sand filter and the return jet. Use a hose to connect the outlet on the filter and the valve on the return jet. Use clamps to hold the connection in place.

Step 5 – Caution

After having installed the sand filter in the salt water pool you need to check the connection. Make sure that the clamps are secured tightly. If not it will lead to leaks and the sand filter will not function properly.

Step 6 – Checking the Reading

There are certain procedures to follow once the sand filter is installed. Pressure reading must be taken on a weekly basis. If you find that the reading is above 10 pounds more than the initial reading, then it is an indication that the sand filter has to be cleaned.

Step 7 – Backwashing

Backwashing is a technique that removes the dirt and debris that have settled on the sand filter. This is attained by reversing the water's flow. This has to be carried out once in four weeks.

Step 8 – Backwashing Technique

The multiport valve on the filter has to be pressed to get it to the backwashing setting. The air hose should be opened and the motor of the pump should be turned on. Switch off the pump only after the water clears off in the hose. The rinse option should be left on for 30 seconds.

Step 9 – Maintaining the Filter

A crucial point while using the sand filter is to know when to replace the sand. As a general rule, the sand has to be replaced once in four years.

Step 10 – Replacing the sand

In order to replace the sand, you need to first drain out the filter by taking off the plug. Remove the multiport valve or the dome. Take out the sand from the filter with the help of an industrial vacuum cleaner. Replace with new sand.

Step 11 – Tip

When you replace the sand, make sure you follow the manufacturer’s instructions. Generally, filling the filter up to 75% should do the trick.

Step 12 – Caution

While using the sand filter, if you find leaks, they have to be fixed immediately. Use silicon sealers to cover up the leaks.
