How long does a Hayward sand pool filter last?

3-5 years
On average, sand should be replaced every 3-5 years. This may be longer if the pool stays clear, or shorter, if the filter runs all the time. The jagged edges of the sand wear down and become smooth as the sand ages.

How do I know what size Hayward filter I need?

Filter Size The filter flow rate must be rated at least the same GPM as your pump, or higher. With pool filters, it’s best to err on the larger size so it can handle the power of your pump. A helpful rule of thumb is to choose a filter with at least 1 square foot per 10,000 gallons pool capacity.

How do I figure out what size pool filter I need?

Multiply the average depth by the surface area to find the total volume. Or, wrap it all into one formula: L x W x D = V. This is the volume of your pool. If your pool is “L” shaped then break it into two (or more) rectangles and calculate the volume of each, then add the volume together.

How long should you backwash a pool filter?

After the hose fills with water, backwash your sand filter for 2 – 3 minutes, or until water runs clear. Shut off the pump motor and push the T-handle back down into locked position. Turn your pump back on and note the lower pressure.

What does backwashing a pool do?

The process of backwashing dislodges trapped debris and contaminants, flushing them out through your value’s waste line or a hose that is connected to the pool pump. When the filter media is clean, the pressure gauge is lower and water can easily flow in and out of the system.

How do I know which pool filter I have?

All pool filters are labeled with an information tag on their tank. This tag includes the name of the manufacturer, model name, the various sizes of the filter in that line of models. The size of your specific unit should be marked or highlighted on this tag.

Do you vacuum a pool on backwash or waste?

If you do have this option, it is highly recommended that whenever you have algae, you will need to vacuum to waste. This option allows you to vacuum the algae up and send it out through the backwash line, avoiding getting algae into your filter sand.

What size filter do I need for a 15000 gallon pool?

So for a 15,000-gallon pool, I suggest a 300 sq ft filter, for a 20,000-gallon pool a 400 sq ft filter and for a 30,000-gallon pool a 500 sq ft filter. You can use a smaller filter if you choose, just note that you will be cleaning it often and the water flow may not be as efficient as going with a larger filter.

Do you rinse after backwashing a pool?

In order to prevent residual blow back into the pool, once you’ve finished backwashing it’s highly advisable to rinse the filter. Just as the backwash lifts and flushes the sand, the rinse resets the sand to its original position for optimum filtration.
