Quick overview

  • 53 square inches of zinc A large sacrificial surface, which is what sets how long the anode lasts.
  • Connects to the metal it protects The anode connects directly to a metal filter or heater core.
  • Clear PVC housing You can see the zinc without cutting into the plumbing, so inspection is a look rather than a job.
  • 2 inch inline body Plumbed into the line rather than hung in the skimmer or the pool.
  • Installation sticker included A weatherproof sticker comes with it so the service date is recorded on the equipment.
  • Sacrificial by design The zinc corrodes so the heater core, filter and other metal in the system do not.

Product details

The Perma-Cast TN-IL-20 is a 2 inch inline sacrificial anode carrying 53 square inches of zinc inside a clear PVC housing.

What a sacrificial anode does

Put dissimilar metals in the same body of water and the more reactive one gives up material to protect the rest. A zinc anode is deliberately the most reactive metal in the system, so it corrodes first and the heater core, the metal filter parts and the rest of the plumbing metal do not. The anode is meant to be consumed, and replacing it is the whole point of fitting one.

How it installs

The TN-IL-20 goes inline in the plumbing and connects directly to the metal filter or heater core it protects. The housing is clear PVC, so you can see how much zinc is left without breaking into the line. A weatherproof installation sticker is included to record the install and the service date on the equipment.

Questions and answers

What people ask about this product, answered by our pool techs.

How much zinc is in it?
53 square inches. That surface area is what determines how long the anode works before it needs changing.
Why is the housing clear?
So the zinc can be inspected without opening the plumbing. You look at it rather than pulling the assembly apart to find out how much is left.
What does it connect to?
It connects directly to a metal filter or a heater core, which is how the anode protects that metal.
What is the sticker for?
It is a weatherproof installation sticker, meant to be applied at the equipment so the install and service dates are recorded where the next person will see them.
