  • Cellulose Fiber’s directions. Also, make sure to backwash the system every week, as this help to clean the sand and keep the system running efficiently.

What should I do when water is leaking from the pre-filter cover?
Open the pre-filter cover, remove the o-ring and apply petroleum jelly or vaseline over the o-ring, replace the o-ring and cover back. Make sure the cover is securely tightened by hand only.

Can I use playground sand or sand from the beach in my sand filter system?
No. Playground sand and sand from the beach or other natural sources will contain impurities and not be uniform in granular size. You must purchase the recommended type of sand for the sand filter system. Sand is available from pool supply stores and many mass merchandisers. Using the incorrect type of sand will cause the system to malfunction and void it’s warranty.

What is the advantage of using a sand filter pump versus a cartridge filter pump?
Sand filtration system requires less cleaning and maintenance of the filtering media compared to cartridge type, and is more cost effective. While filter cartridges have to be replaced approximately every two weeks, the sand in the INTEX Sand Filter needs to be replaced only once every five years.

What size and type of swimming pools is the sand filter pump system suitable for?
The sand filter pump system is suitable for residential above ground pool types with a volume of water up to 94,625 liters or 25,000 gallons.

Why is it necessary to backwash the filter media during the initial setup startup and how long I should backwash the media?
Brand new filter media is typically pre-washed and should not require extensive backwashing. However the transportation process may cause excessive abrasion and create impurities of fine particles in the filter media which require an extended backwash cycle at the initial setup startup. Backwash until clean, clear water runs through the sight glass or drain outlet port, about 3 minutes

My sand filter pump system fails to clean the water properly, do I have the right size for my above ground pool?
A residential sand filter system should be able to turn over the pool volume in approximately 8 hours. An undersized filtration system cannot keep up with the dirt and organic matter introduced into the pool. The INTEX Sand Filter is strong enough for even the largest INTEX pool, the 32’x16’x52″ Rectangular Ultra Frame Pool.

How does a sand filter system work?
The water from the pool flows through the pre-filter, up through the control valve, down through the sand filter media, up through the riser tube in the centre and out through the control valve back to the pool. Particles and contaminates in the pool water are trapped in the sand and clean water is returned into the pool.

How do I remove fine suspended particles?
Fine suspended particles may not be trapped in the filter bed but continue to be circulated in the pool giving the water a cloudy appearance and reducing visibility for bathers. This problem is more likely to occur in an outdoor pool due to the effect of the elements such as wind and rain. The pool water is prone to collect windblown debris like dust, algae, spores, insects and foot borne materials like soil and grit. In order to remove this finely dispersed material the use of a flocculants is necessary. This is a chemical which is added to the pool water and causes the particles to group together to form larger particles (flocks) which become big enough to be caught by the filter media and removed from the water. It should be stressed that flocculants must be used correctly at the recommended dosage rates and this is best achieved by dosing continuously by means of a dosing pump. Supplier’s instructions must be followed. Over flocculation can result in cloudy water, because the flock has nothing to bind to

How often should I change the sand in my filter?
Under normal operating conditions, residential filters should change the sand every 4 to 5 years. In areas with high air contaminants such as dust, leaves or any condition that requires frequent backwashing, the sand may need to be changed every 2 to 3 years.

After loading the filter media into the tank and setting up everything, the water does not flow into the tank after opening the plunger valves (or removing the black hat-shape plugs) and setting the 6-way valve in filter mode?
To ensure water flows into the filter tank make sure both the inlet and outlet have no vacuum or skimmer attached, and open the pre-filter cover to purge air out of the system. Tighten the pre-filter cover back in place after the sand filter system is filled up with water.

What is the warranty period of the INTEX sand filter pump system?
It has a limited warranty of two (2) years from the date of the initial retail purchase. Keep your original sales receipt with Owner’s Manual, because proof of purchase will be required and must be accompanied with warranty claim.

Water is present in the drain/waste outlet port or sediment transparent window, is this normal?
This is an indication that the internal diverter gasket and/or O-ring of the 6-way valve is worn out or torn, and may need to be replaced. Please contact INTEX service station listed on your Owner’s Manual for replacement.

What type and size of media should I use with the INTEX Sand Filter system?
The most common media used is sand filtration. The recommended type is No. 20 grade silica sand, with specification of 0.45 to 0.85mm (0.018 to 0.033 inches) with a Uniformity Coefficient less than 1.75. Too fine of a grade of sand will clog too quickly, and too soft of a sand will break up and also cause clogging. Intex offers glass media as well, which is a better cleaning solution than sand. The particle size is 0.4 to 0.8mm.

How do I verify if the pressure gauge is faulty?
The pressure gauge should drop to zero “0” when the motor is turned off. If it is faulty contact your INTEX Consumer Service Center to replace it.

What should I do when water is leaking from the flange clamp?
Turn off and unplug pump. Remove the flange clamp, open the 6-way valve cover and make sure the tank o-ring is sitting properly on the tank groove and free of sands or debris. Replace all the components back and tighten the flange clamp bolt securely with the wrench supplied.

Does the sand filter pump system include hoses or other fittings to attach to an INTEX swimming pool?
It includes two hoses of 38mm (1.5in) diameter. Plunger valves fittings and adaptors B to fit smaller size pools with 32mm (1.25in) diameter hose fittings are available for purchase separately.

How do I handle the glass media?
For a safe handling, some precautionary instructions must be observed. Avoid creating dust when handling, using or storing crushed glass filter media. Always use respiratory protection, eye protection and wear gloves when handling. If sweeping up spilled material, dampen with water to avoid airborne dust formation. Pour material slowly into tank. If lung irritation occurs, move to fresh air and consult a doctor. If eye irritation occurs, flush eyes with fresh water for at least 15 minutes. Consult doctor if irritation persists.

What should I do if sand is returning to the pool during filtering operation?
Sand that is too fine will pass through the filter grid plate. Make sure only No. 20 grade Silica Sand (0.45 to 0.85 mm (0.018 to 0.033 inches) with a Uniformity Coefficient less than 1.75) is used. Also if the filter tank is not level, channeling can occur. If the sand bed is channeled, high water flow through the channeled area will break up the sand and allow it to return to the pool. Replace the sand with the correct type, size and amount, and ensure the filter tank is level. Refers to the owner’s manual for details.

How often should the glass media be replaced?
Every 8 or 9 years under normal operating conditions.

What size of sand filter pumps does INTEX distribute and what are the specifications?
INTEX distributes one size of sand filter pump with the following specification: Specifications of INTEX Sand Filter Pumps

How many functions does the INTEX sand filter control valve have and what are the functions?
