If you're tired of manually dumping chemicals into your pool every other day, installing a rola chem chlorine feeder might be the best decision you make this season. It's one of those "set it and forget it" pieces of equipment that actually lives up to the hype, helping you maintain that crystal-clear water without the constant guesswork.
Owning a pool is supposed to be about relaxing, but sometimes it feels like a part-time job. You're constantly testing the water, lugging heavy jugs of liquid chlorine, or dealing with those slow-dissolving tablets that never seem to get the levels quite right. That's where a reliable feeder system comes into play. It takes the manual labor out of the equation and replaces it with a steady, automated drip that keeps your chemistry stable.
How the Rola Chem System Actually Works
The magic behind the rola chem chlorine feeder is its peristaltic pump design. If you aren't familiar with that term, don't worry—it's just a fancy way of saying the machine uses a rotating roller to squeeze a flexible tube. As the rollers turn, they push the liquid chlorine through the tube and into your pool's circulation line.
What's great about this design is that the chemical itself never actually touches the mechanical parts of the pump. It stays inside the tubing. This is a huge deal because chlorine is incredibly corrosive. By keeping the "nasty stuff" contained within a replaceable tube, the pump motor and internal gears last a lot longer than they would in other types of delivery systems.
It's a simple, mechanical process that doesn't require a computer degree to understand. You set the timer or the feed rate, and the pump does the rest. It's consistent, predictable, and frankly, a lot more reliable than hoping the wind doesn't blow all your chlorine out of a floating dispenser.
Why Consistency Matters for Pool Health
We've all been there: the pool looks great on Friday, you get busy over the weekend, and by Monday afternoon, the water has that suspicious cloudy tint. Once algae starts to take hold, you're spending a fortune on "shock" treatments and scrubbing the walls.
A rola chem chlorine feeder prevents those "peaks and valleys" in your chlorine levels. Instead of dumping a gallon of liquid in at once—which sends your levels sky-high and then lets them crash over the next 48 hours—the feeder provides a constant, low-level flow.
This steady state is much better for your pool's liner, your filtration equipment, and honestly, your skin and eyes. High spikes in chlorine can be harsh on swimmers, while low dips allow bacteria to grow. Keeping things right in the "sweet spot" is the secret to a low-maintenance pool, and automation is the only real way to achieve that.
Getting the Installation Right
Setting up a rola chem chlorine feeder isn't as intimidating as it looks, but you do want to be careful. Most people mount the pump on the wall near their pool filter and heater. You'll need a power source, usually a standard 120V outlet, though some models are hardwired into the pool's time clock.
The most important part of the setup is where you inject the chlorine. You want the injection point to be the last thing in your equipment chain before the water goes back to the pool. If you inject chlorine before your heater, that concentrated chemical is going to eat through your heater's copper heat exchanger in record time. Always put the feeder after the heater and the filter.
You'll also need a large vat or tank to hold your liquid chlorine. Most people use a 5-gallon or 15-gallon heavy-duty plastic container. The pump sits above it, pulls the liquid up through a suction line, and pushes it out through the discharge line into your plumbing.
Maintenance Tips to Keep Things Running
Nothing is truly "maintenance-free," and the rola chem chlorine feeder is no exception. However, the maintenance is pretty minimal if you stay on top of it.
The main thing you have to watch is the squeeze tube. Since this tube is constantly being compressed by the rollers, it eventually wears out. Think of it like the tires on your car—they're designed to be replaced. Most pool pros recommend swapping out the tube once a year, usually at the start of the season. If you wait until it cracks, you'll end up with chlorine leaking inside the pump housing, which can get messy.
It's also a good idea to check the injection fitting where the tube meets your PVC pipe. Over time, calcium or chemical buildup can clog that small opening. A quick soak in a weak acid solution or even just poking it with a small wire can clear it right up. If the pump is running but no chlorine is moving, a clogged injection fitting is almost always the culprit.
Winterizing Your Feeder
If you live somewhere where the ground freezes, don't forget your feeder when you close the pool. Liquid chlorine can freeze, and if it's sitting in the lines, it can cause them to burst. I always suggest running some fresh water through the pump at the end of the year to flush out the chemicals, then removing the squeeze tube so it doesn't stay compressed and "set" in a flat shape all winter.
Troubleshooting Common Quirks
Sometimes you'll notice the pump motor is spinning, but you don't see any liquid moving through the clear lines. This is usually caused by an air leak. Check your connections at the suction end—if the nut isn't tight or the tubing has a tiny pinhole, the pump will just suck air instead of chlorine.
Another common issue is "loss of prime." If your chlorine tank runs dry, the pump fills with air. Once you refill the tank, you might need to help the pump get started again by ensuring the suction line is fully submerged and the tube is lubricated. Rola Chem usually provides a little bit of silicone lubricant for the squeeze tube; using this helps the rollers move smoothly and prevents the tube from overheating.
Choosing the Right Model for Your Pool
When you start looking for a rola chem chlorine feeder, you'll notice they come in different "series" (like the RC25 or RC103). The main difference is the feed rate—how many gallons of chlorine they can pump in a 24-hour period.
For a standard backyard pool, you don't need a massive commercial-grade pump. A smaller model that puts out a few gallons a day is usually more than enough. If you get a pump that's too powerful, you'll find yourself trying to set the timer for 2 minutes an hour just to keep the levels down, which is overkill. It's better to have a pump that runs a bit longer at a lower rate to ensure even distribution.
Wrapping It All Up
At the end of the day, a rola chem chlorine feeder is about taking back your weekends. Instead of being the "pool scientist" every afternoon, you can just glance at the clear tubing to make sure things are moving and get back to actually swimming.
It's a rugged, straightforward piece of gear that has been a staple in the industry for decades. It's not flashy, and it doesn't have a bunch of unnecessary bells and whistles, but it does exactly what it's supposed to do: it keeps your water safe and clear. If you're tired of the manual dosing dance, this is definitely the way to go. Just remember to change those squeeze tubes once a year, and you'll be set for a long, stress-free summer.
