Product Description

TagelusTop Mount Fiberglass Sand Filter The design that revolutionized a timeless technology Sand filters are one of the most popular ways to filter water. For good reasons. They are simple, effective,and require very little attention. Pool water is routed through a sand-filled pressure vessel. The sand traps particles large and small…so small they are undetectable to the human eye. Over time, dirt accumulates in the spaces between the sand particles causing the pressure in the vessel to rise as water finds it harder to pass through. This signals you to “backwash” the filter. Simply reverse the water flow and “knock out” the dirt. What could be simpler.

But all sand filters are not created equal. For optimum filtration all the water must flow through the same amount of sand at the proper rate. That’s why all Pentair sand filters feature a special internal design that keeps the sand bed level, ensures even water flow, and results in the most efficient filtration possible. That’s why more than 2 million Pentair filters have been installed worldwide. Tagelus provides consistent, high performance cleaning of every gallon of water that passes through it. The key is a combination of design features that eliminates “channeling”—a condition that allows water to race through the filter too quickly for effective cleaning.

Standard features include:

1. Patented process creates a one-piece, corrosion resistant,fiberglass reinforced tank of unmatched strength and durability.
2. Six-position Hi-Flow™ valve has built-in pressure gauge, manual air relief valve, and sight glass to make inspection,and routine maintenance fast, safe, and easy.
3. Exclusive internal design ensures optimum flow characteristics for more efficient filtration, long filter cycles, and economical operation.

Tagelus filters are known around the world for their ability to deliver clean, clear water, with minimal maintenance. Their time-proven design ensures trouble-free
performance and long life.

Additional features include:

  • 360° diffuser keeps sand bed flat and level to eliminate channeling and extend filter cycles.
  • Combination sand and water drain speeds servicing and winterizing.
  • All internal parts are threaded for ease of service.
  • One-year limited warranty. See warranty for details.

We need to replace the diverter gasket for our Tagelus/Pentair Sand filter p/n 144126 Serial #0105271110047S, upc#42856202 date Sept. 28, 2011, we also need to replace the 6 screws for the top, thank you for any help and specific part number we need. I live in St. Maarten Dutch side in the Caribbean, my pool supply company does not have the proper gasket and I am trying to locate it on the French side at AquaTec Pool supplies.

Hi Tamara, The diverter gasket is only sold glued into the diverter so you would require this Diverter W/ Glued in Diverter Gasket If you need the screws for the top then I would suggest this Complete Upper Handle Assembly as this will be the most economical way to purchase the needed parts.

What size/ model pump is recommended for this filter?

A  Answered on 6/13/2018 by InyoPools Product Specialist Lennox H.

Hi. You will need a pump that will generate a flow rate of 40 GPM or less. You can check out Inyo's How to Size a Pool Pump guide.

Measuring filter height Do I include the tank stand or just measure from the bottom of the tank to the top of the valve switch? Not original owner and have no paperwork, but know the filter is from mid- to late-90's. Label says Tagelus, but tank is black and most resembles Cristal Flo II polyethylene top-mount six-position valve in current Pentair sand filter line. I cannot read the model spec section of the label well enough to determine if a model number is indicated. Thanks.

A  Answered on 7/3/2017 by InyoPools Product Specialist Lennox H.

David. You will have to measure the total height of the unit including the base.

What is the rated pump size to get the flow ratings as listed? (19,200 - 8hrs and 24,000 - 10hrs)

A  Answered on 5/15/2017 by InyoPools Product Specialist Lennox H.

Hi, Al. The pump flow rate is based on the pool's Feet of Head. If you get us that info we can size a pump that would provide the appropriate flow rate.

When should I change the sand in my filter?

A  Answered on 1/27/2012 by InyoPools Product Specialist Patrick P.

You should change the sand in your filter every 5-7 years. You can generally tell that it is time if your pool water is not as clear as it normally is or when you notice the interval between backwashes is shorter. You can use > this guide to walk you through it.
