Inground Pool Equipment Selection Part 4: Sanitizers

Hello and welcome Inyo fans, this is a continuation of Inyo Pool’s equipment selection series. In this chapter, we are focusing pool sanitation and all the different ways it can be accomplished. 

We’ll be explaining the functionality, sizing, and the advantages of the three basic categories of santizers:

  • Chlorine tablet feeders,
  • Salt Chlorine Generators; and
  • Alternative Sanitizers (e.g. Mineral Cartridges, Ozonators & Ionizers)

Chlorine Tablet Feeders

There are three common types of tablet feeders:

  • Floating Dispenser
  • In-line Feeder
  • Offline Feeder

how does a chlorine pool float work?
The simplest of all of the tablet feeders is the Float. A chlorine float is a floating plastic vessel you fill with chlorine tablets. The float acts like a chlorine teabag, releasing sanitizing chlorine to keep your pool clean. The float is the easiest of the feeders to maintain but it is the least efficient way of chlorination. The float dissolves the chlorine relatively slow so once it falls behind in chlorine production it struggles to maintain a clear pool.

The Inline and offline chlorine feeders are the preferred chlorine tab vessel for pool owners and service companies. They provide the user the ability to dial down or up chlorine dosages and they are usually more durable than chlorine floats.

The inline chlorinator is installed “in-line” with your pump and filter. The inline chlorinator is plumbed on the pipe after your filter (and heater) dissolving the chlorine into your return line. In-line chlorinators are found on new installations or full renovations as the installer can better plan for the vessel’s installation. Because the inline requires a stretch of horizontal pvc on which to be installed, and head clearance so you can remove the cap, replumbing is sometimes needed.

Offline chlorinators are ideal for cramped equipment pads, as they can be sat several feet away from pvc. Offline chlorinators use feeder tube (about 1/8″ to 1/4″) to divert water to and then feed it back to the main pool plumbing line. The installation only requires to small whole to be drilled into the pipe while the vessel is installed out of the way.The offline allow the user to adjust chlorine dosage using the control knob.

Offline chlorinators are normally found on pools that are being retrofitted. The installation is very simple because no cutting is required. You simply have to drill two holes for the inlet and return tubing.

Now we’ll move on to a sanitizer that is quickly becoming a favorite among new pool builders; and that’s salt chlorine generators. Once a rarity, salt chlorinators are cropping up in backyards everywhere as tales of the generator’s simplicity and light maintenance load, spread.

Salt chlorine generators consist of two main parts, the power panel, and the electrode cell. The power panel normally doubles as the control center for the generator, where the user can check the water’s salt levels, the health of the cell and any fault alerts happening within the generator’s system.
