Pentair's Rainbow chlorinators are known in the market to be some of the most heavy-duty, high-capacity feeders that provide automatic sanitation for residential or commercial pools of up to 658,500 gallons. This is possible because of Pentair's technologies' ability to operate effectively and efficiently with slow-dissolving trichlor or bromine tablets.

Whether you are getting 300 and 320 Series filters in clear amber for easy tablet level monitoring, the Rainbow chlorinators you have will be designed to have a completely enclosed system with no special venting required and a 50 PSI maximum operating pressure.

Despite such use cases, Pentair's Rainbow Automatic Chlorine/Bromine feeder will still be subject to a definite lifespan. We can address this concern by creating this category as the reference site for all the genuine replacements you need in case your chlorinator no longer functions as intended or its positive external no-clog control valve is already running spotty.

The first component we have in this list is the: O-283-9 Aladdin Pentair Rainbow Chloronator Lid Oring Minn. 8343-60 Duro 35505-1425 154005. What this component offers is the ability to help ensure that no escaping gases occur in your feeder, maximizing the fact that all Rainbow Feeders are already NSF Listed.

Another component you may need replacing is the: R172283 Pentair Chlorinator Extension 20". To avoid replacing this part and others, make sure that you install the chemical feeders after a pool heater, ensuring that the 50 PSI maximum operating pressure is respected. Remember, too, that the feeders are for permanent installation in return line of new or existing pools or spas.

It's important to remember also that extreme care must be exercised when adding chemicals to your pool with these chlorinators. Concentrated chemicals may react violently if they mix in the chemical feeder, causing untoward incidents, ranging from property damage, device harm or personal injury with lethal consequences.
