Download Commodity

Choosing the right filter for your puddle is non always like shooting fish in a barrel. However, before purchasing your filter, it is best to know every detail well-nigh your pool and so you lot tin can buy the all-time filter possible. Then, you can get out and get a filter then you'll have perfectly make clean pool water to leap into.

Steps

i
Notice the surface surface area and the volume of water your pool tin can concord. Pools come in all types of shapes. Even so, there are ii common kinds: rectangular and circular. Depending on the one you've purchased, make certain you've correctly calculated its size with the correct mathematical formula.^[1]
- Rectangular pools are by far the nearly uncomplicated to measure. Only multiply its length with the width. Surface area = Fifty x Westward
- If you lot opt for a circular pool, perhaps a hot tub or a smaller children'southward pool, the calculation involves taking the radius of the circle, raising information technology to the power of ii, then multiplying the product with 3.14. Surface expanse = 3.14 x r^two
- Measuring your puddle's surface area yourself works well, only if you just bought your pool, then measurements should be provided upon purchase.
2
Notice the pool's maximum book of h2o. Then, employ your pool'due south volume to find out how much water can move through your filter in about a infinitesimal. This is called ''flow charge per unit''. The flow rate differs from the kind of pool yous have. Ensure you calculate with this in listen to get the almost out of the eventual filter y'all will utilize.
- To find your puddle's volume, take the maximum volume of water your pool can hold (this amount can be institute upon purchasing of your puddle) and divide information technology past 360. This will tell you how many gallons of water that goes through your filter in a minute.
- Information technology's all-time to get a filter that is slightly oversized for your pool to ensure maximum efficiency.
- If the flow rate for the filter is too much and the functioning pressures for the filter are too high yous tin can increment the pipe size of your plumbing organisation, in function or in whole, and this volition reduce the operational pressure of your system.
- All filters accept a minimum and maximum flow charge per unit that the pump must fall within. Likewise weak or likewise much flow and the filter will not operate correctly. Brand certain the filter you lot get is able to adapt for the amount of water in your pool.

Plant your pool's turnover charge per unit. This ways knowing how long information technology takes for the water to completely cycle through the filter. Nigh municipal health codes crave a minimum filtration turnover rate of two complete turnovers of the water in a 24 hr period.^[two]
- The minimum turnover charge per unit is one that turns over the unabridged pool once in 12 hours. A turnover rate of 8 or ten hours is the typical sizing rates for pools today.
- If the pool is for commercial, semi commercial or high bather turnover applications then you will want to choose a filter that will allow you to turn over the entire volume of water at least four times every 24 hour period.
4
Choose the right filter. The correct filter size depends on the size of the puddle. To maintain skillful water clarity yous must run the pump each 24-hour interval then that all the water in the pool is turned over. All filters have gallon per minute design rating and turnover charge per unit.^[3]
- For instance: A 24 feet (7.3 m) round above ground pool has approx 13,500 gallons (51,103.1 L). A Hayward S166T Sand Filter has a 10hr turnover rate of eighteen,000 gallons (68,137.4 L) and would work well with this pool.
5
Consider how much water resistance there will be that can touch your pool'south turnover rate. The faster water moves through the pump, the more resistance yous'll accept.^[four]
- Choose a filter that would at a minimum turn your pool over in 10hrs. With filters information technology is okay to become bigger.. Larger filter areas will help to maintain proficient water clarity.
- Remember that the faster the velocity of water moving through the plumbing arrangement, the more resistance to flow the water has. This ways a slower pump similar depression speed on a two-speed pump has a menstruation increase per unit of power on lower speeds versus the high-speed option. Note that nearly 2 speed pumps prepare to depression speed will non meet the minimum catamenia requirements for the filter to office properly.
six
Have all the information gathered about your pool to find a suitable filter size. By using a uncomplicated equation you should have no issues. Before putting information technology all together make certain you've correctly calculated the pool'due south book (in gallons) and decided on a reasonable turnover rate for all the water to be cycled through the filter. The equation used in computing filter sizes is:
- Pool capacity in gallons divided by the desired turnover rate in hours.
- This will give you the minimum menstruum needed in gal/m (Gallons per minute).
- Carve up this number by 60 to become the gal/m.
- Find a pump that meets the gal/m you simply calculated.

Question

What size pool is a Haywood DE 2400 filter used for?

That filter has been discounted and replaced with DE 2420, which is a 24 square foot filter size or 48 GPM or 2,880 GPH rated pool.
Question

I take a circular pool v.4m and i.12m deep. It is heated to 35 C, so I would like to run the pump 24 hours. Which size filter do I need?

Beginning, you might desire to reconsider running a pump 24 hours. It's a waste product of energy. As for filters, effort a 24-inch Sand Filter, or 100 sq ft. Cartridge Filter, or 24-inch D.Eastward Filter.

How oft do I need to change the sand?

When yous detect your backwash more than necessary, you should change it. However, if y'all notice sand in your pool at the outlets, then it is not the sand. You lot have a broken lateral, and must remove the sand to repair; so you might besides supercede sand then equally well.

If the purchase receipt describes my filter as nineteen", what dimension is that?

This is the diameter of the filter tank, typically (if information technology's a sand filter). To go the surface expanse for a filter this size, you lot would want to use the formula for the area of a circle with a radius of 19" divided past two. In this case the surface area is approx. 1.24 ft^ii.
