Choosing the correct filter for your puddle is non always easy. However, before purchasing your filter, it is best to know every detail most your pool then you can purchase the best filter possible. And so, you can become out and go a filter and then you'll take perfectly clean pool h2o to jump into.

Steps

1
Find the surface area and the book of water your pool can hold. Pools come in all types of shapes. However, there are ii common kinds: rectangular and round. Depending on the one you've purchased, brand sure you've correctly calculated its size with the right mathematical formula.^[1]
- Rectangular pools are past far the about elementary to measure. Simply multiply its length with the width. Surface area = Fifty x Westward
- If yous opt for a round pool, mayhap a hot tub or a smaller children's pool, the calculation involves taking the radius of the circle, raising information technology to the power of two, so multiplying the product with 3.14. Surface area = iii.14 x rⁱⁱ
- Measuring your pool's surface area yourself works well, but if you but bought your pool, then measurements should exist provided upon purchase.

Observe the puddle'due south maximum volume of water. Then, utilise your pool's book to find out how much water tin move through your filter in most a infinitesimal. This is called ''flow rate''. The flow rate differs from the kind of pool y'all accept. Ensure you summate with this in mind to get the most out of the eventual filter you volition utilize.
- To find your pool'southward volume, have the maximum book of water your puddle can hold (this amount tin be found upon purchasing of your pool) and divide it past 360. This will tell you how many gallons of water that goes through your filter in a infinitesimal.
- Information technology'southward all-time to go a filter that is slightly oversized for your pool to ensure maximum efficiency.
- If the menstruum rate for the filter is also much and the operation pressures for the filter are too loftier y'all can increase the pipe size of your plumbing system, in role or in whole, and this will reduce the operational pressure of your organisation.
- All filters take a minimum and maximum flow charge per unit that the pump must fall within. Too weak or too much flow and the filter will not operate correctly. Make sure the filter you go is able to suit for the amount of h2o in your puddle.

Establish your pool'southward turnover rate. This ways knowing how long it takes for the water to completely cycle through the filter. Nigh municipal health codes require a minimum filtration turnover rate of 2 consummate turnovers of the h2o in a 24 hour period.^[2]
- The minimum turnover rate is 1 that turns over the unabridged pool once in 12 hours. A turnover rate of eight or 10 hours is the typical sizing rates for pools today.
- If the pool is for commercial, semi commercial or high bather turnover applications and then yous will want to choose a filter that will let you to turn over the unabridged volume of water at least 4 times every 24 hr flow.
4
Choose the correct filter. The correct filter size depends on the size of the pool. To maintain good h2o clarity you must run the pump each day then that all the water in the pool is turned over. All filters have gallon per minute blueprint rating and turnover charge per unit.^[3]
- For example: A 24 feet (7.3 m) round in a higher place basis puddle has approx 13,500 gallons (51,103.i L). A Hayward S166T Sand Filter has a 10hr turnover rate of 18,000 gallons (68,137.4 Fifty) and would work well with this puddle.
5
Consider how much water resistance in that location volition exist that can affect your pool's turnover rate. The faster water moves through the pump, the more resistance you'll have.^[4]
- Choose a filter that would at a minimum turn your pool over in 10hrs. With filters it is okay to go bigger.. Larger filter areas will help to maintain good h2o clarity.
- Recollect that the faster the velocity of water moving through the plumbing organisation, the more resistance to flow the water has. This means a slower pump like low speed on a ii-speed pump has a menstruum increase per unit of ability on lower speeds versus the high-speed option. Note that most two speed pumps set to low speed will non meet the minimum menses requirements for the filter to function properly.
vi
Take all the information gathered about your pool to detect a suitable filter size. By using a simple equation you should accept no problems. Before putting it all together make sure you lot've correctly calculated the pool's volume (in gallons) and decided on a reasonable turnover rate for all the h2o to exist cycled through the filter. The equation used in computing filter sizes is:
- Pool capacity in gallons divided by the desired turnover charge per unit in hours.
- This will give you the minimum period needed in gal/m (Gallons per minute).
- Divide this number by 60 to get the gal/m.
- Find a pump that meets the gal/m you but 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 two,880 GPH rated pool.
Question

I have a circular pool v.4m and 1.12m deep. It is heated to 35 C, and then I would like to run the pump 24 hours. Which size filter practice I demand?

Outset, yous might desire to reconsider running a pump 24 hours. It's a waste of energy. Equally for filters, try a 24-inch Sand Filter, or 100 sq ft. Cartridge Filter, or 24-inch D.E Filter.
Question

How ofttimes exercise I need to change the sand?

When you notice your aftermath more than necessary, you lot should modify it. Withal, if you notice sand in your puddle at the outlets, so it is non the sand. Y'all accept a broken lateral, and must remove the sand to repair; so you might also replace sand then as well.
Question

If the buy receipt describes my filter as 19", what dimension is that?

This is the bore of the filter tank, typically (if it'south a sand filter). To go the surface surface area for a filter this size, y'all would want to use the formula for the surface area of a circle with a radius of xix" divided past ii. In this case the surface area is approx. 1.24 ft^2.

A list of common pool sizes, their respective gallons, a list of pop filter sizes and their ratings will help your selection procedure.
Telephone call the manufacturer of your pump and they can assist yous with determining the approximate caput resistance (ft / lbs) of your plumbing installation. You will need this information in order to calculate how many gal/grand your pump delivers.
Two speed pumps are constructive at meeting minimum turnover values while using as little electricity as possible. Try using ii filters for maximum efficiency.
The filter that you lot cull should have a maximum designed flow rate approximately fifteen-xx percent higher than the calculated gal/1000 that your puddle pump supplies.
Nigh older filters are designed for a maximum thirty psi where newer filters are rated maximum operation pressure of 30 psi and maximum total pressure of 50 psi.

The pressure inside a filter tank is more than enough to crusade extreme impairment. Never attempt to open the filter while under pressure and be sure to have the filter inspected past a professional should you lot observe any leaks or issues that could be structural.
