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.

Have Tagalus100d. No air bleeder valve on the filter. How am i supposed to decompress it when priming the pump?

A  Answered on 12/9/2020 by InyoPools Product Specialist Hector F.

Hi Eugene, another way to release the water when priming the pump is by placing the multiport valve in the waste position before priming the pump and once it releases water while the prime fills with water to then turn off the pump, place the valve back into the filter position then turn the pump back on.

I have TA100D. This does not have a pressure relief valve. Can you explain why. How am I supposed to clean the pump basket without pressure relief and without introducing water into the basket Thx

A  Answered on 1/8/2021 by InyoPools Product Specialist Hector F.

Hi Eugene, the multiport valve that comes with the filter does have an air relief valve located on the side of it.

A  Answered on 11/5/2018 by InyoPools Product Specialist Hector F.

The spider gasket for the multiport valve is dependant on the model of the valve. You can call in and provide that model so we can cross reference that for you or if that model number is not legible then you can always take a few pictures of it to upload@inyopools.com so we can assist.

Besides the top valve, what is the difference between this and the Triton series? Is one better than the other? Thanks

Our pool is 30,000 gallons concerned the TA-60D is too small is the TA-100D over kill???

A  Answered on 5/31/2016 by InyoPools Product Specialist Patrick P.

Hi JoAnn, If you can go larger on the filter it is always recommended as you put less stress on your motor prolonging its life. The filter can also filter out more debris and gives you more time between cleanings.

?     Asked on 5/23/2016 by John Davidson

What filter do you have that is comparable to the Nautilus NS 36 model. Also with hookups being in the same position.

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.
