King Technology Perform-Max 980 In-Line Pool Feeder
Automatic sanitizing on cue.
The King Technology Sani-King Perform-Max 980 In-Line Feeder (PST-01050980, MPN 01-05-0980) automatically doses your in-ground pool with chlorine or bromine so you stop hand-feeding tablets every few days. It plumbs in-line after your filter and heater, holds a full 10 lbs of 1" or 3" tablets, and treats chlorine pools up to 50,000 gallons or bromine pools up to 25,000 gallons. This 980 configuration ships as the Perform-Max in-line body with 2" FPT ports plus 2" MPT x 1/2" FPT reducer bushings, so you can adapt it to your existing return plumbing.
Why PST Customers Pick This
Patented Performance Valve
The Performance Valve responds accurately to each setting on the dial, so output tracks your adjustment instead of drifting. It is the only bulk feeder valve engineered for exact erosion metering across a wide range.
Bottom-Layer Erosion
Water erodes only the bottom layer of tablets rather than soaking the whole stack. That keeps chemical output steady and predictable instead of spiking when a full load gets wet.
In-Line Installation
Installs directly in your return line after the filter and heater. Works with 1-1/2" or 2" plumbing, so it drops into most standard in-ground equipment pads.
Chlorine or Bromine
Runs on 1" or 3" chlorine or bromine tablets, pucks, or sticks. Choose your sanitizer and dose the whole pool from one feeder, no floating dispenser to fish out.
Reducer Bushings Included
This 980 setup adds 2" MPT x 1/2" FPT reducer bushings to the 2" FPT feeder body, giving you flexibility to match your existing pipe size and fittings.
10 lb Holding Capacity
The tall chamber holds a full 10 lbs of tablets, roughly 20 large 3" pucks, so you refill less often and keep sanitizer levels stable between service visits.
Chemical Handling
Never mix chlorine and bromine tablets in the feeder, and never switch sanitizer types without fully emptying, flushing, and drying the chamber first. Combining the two, or loading tablets into a feeder that still holds residue of the other, can trigger a violent reaction, release toxic gas, or cause a fire. Always relieve system pressure and shut off the pump before opening the cap, then add only one type of dry tablet at a time.
Specifications
Frequently Asked Questions
What is the difference between the Perform-Max 940, 960, and 980?
They share the same Perform-Max body and Performance Valve. The 940 is the standard in-line, in-ground feeder with 2" ports. The 980 is that same in-line feeder supplied with 2" MPT x 1/2" FPT reducer bushings so you can adapt it to different plumbing. The 960 is the off-line version that tees off the return line. This listing is the 980 in-line configuration.
What size pool does this feeder treat?
The Perform-Max 980 handles chlorine pools up to 50,000 gallons and bromine pools up to 25,000 gallons. The multi-setting dial lets you dial the dose down for smaller pools, so it fits most residential in-ground pools comfortably.
Can I use bromine instead of chlorine in this feeder?
Yes. The Perform-Max runs on either chlorine or bromine tablets, pucks, or sticks in 1" or 3" sizes. Pick one sanitizer and stay with it. If you ever switch, completely empty, flush, and dry the chamber first, since mixing the two chemicals is dangerous.
Where does it install in my plumbing?
It plumbs in-line on the return side, after the filter and heater and before the water goes back to the pool. It works with 1-1/2" or 2" plumbing, and the included 2" MPT x 1/2" FPT reducer bushings help you match your existing fittings.
Can I install this feeder myself?
A handy pool owner can install it, but it requires cutting into your pressurized return line and making sealed threaded connections, so plan for pipe, primer, and glue. Always install it after the heater so undiluted sanitizer never sits against the heat exchanger. If you are not comfortable cutting live plumbing, have a licensed pool professional set it, which also keeps the manufacturer warranty intact.

Let customers speak for us
The only place I could find with the part I needed. Delivery was fast and the price was great. Best pool supply store on the web.
Part was easy to find and arrived a couple of days earlier than originally scheduled.
The ceramic spindle in the center of the original impellor broke. Replacement with this part was super easy and pump performs like new.
Ease of purchase replacement part took care of the problem
Received the correct replacement part. Not a real tough job. Part works great!
Better than the PA version at fraction of the cost.
Just what I needed for my syllent pump that comes with no Jacuzzi pump coupler. Do need a 1 1/2x1 1/4 reducer but everything will work out just fine..
This product seems to work great so far! I’m only two days in but the leak around my steps seems to have been completely stopped after applying this
All went well. Fast shipping AAAAAAAAAAA++++++++++++
Our pool and spa are over 25 yrs old. When the spa air button stopped working, we found that it was no longer avaliable. We did some online searching and found that this was a good replacement option and found it on the PST Pool Supplies website. We ordered it and once it arrived, we were very happy that we were able to install it and it worked fine.
Exact replacement Weir door that fit perfectly! Solved the problem of my old worn out doors!
