ABG Compensator, Winterizing Accessory CST001
Give the ice somewhere else to go.
ABG Compensator, part CST001 is a pool closing accessory stocked under SKU PST-CST001. Compensators sit in the skimmer and take up the pressure of expanding ice so the skimmer wall does not, and blowout plugs let you clear a line with air and then hold it sealed, and both come down to the same thing: no trapped water where a freeze can split a fitting. Match the size in the part name to your skimmer or plumbing before ordering, then set it as the last step of the closing.

What does a skimmer compensator actually do?
It stands in the skimmer and gives freezing water something soft to push against. Water expands as it turns to ice, and if the only thing in the skimmer is water and concrete or molded plastic, the wall is what gives. A compensator absorbs that expansion so the skimmer survives the winter intact.
What is a blowout valve plug for?
It lets you install the plug first and clear the line second. Compressed air passes through the valve, pushes the water out, and the valve closes when the air stops, so the line keeps its air lock and water does not run back in. It saves the scramble of trying to seat a plug while a line is still blowing.
Do I still need the rest of the winterizing kit?
Yes. Freeze protection is a system: lower the water, blow the lines, plug the returns, protect the skimmer, and cover the pool. A compensator or blowout plug covers one link in that chain, and the chain is only as strong as the piece you skipped.

Let customers speak for us
The bulb was lost in transit and PST reached out proactively to ask if I wanted a replacement shipped out!
part was an exact fit for my old spa, price was great thanks
Fast shipping and great customer support. I appreciate all of the help in getting my spa up and working.
The cord worked perfectly when I upgraded my older Balboa spa and pump.
I had a leak in which water was leaking out to the waste line. I could hear the water trickling in the waste line. The spider gasket in this kit resolved the issue.
Shipping and delivery were quick. Would definitely order again from PST.
Fit perfectly and works great.
Awesome item. I can control my spa from my phone!! Love it. Item was shipoed out and delivered so fast. Hooking it up was a breeze.
The support staff to make the orders were outstanding; even though I made a quantity error. And the timeliness of all the repair parts I needed to get the OLD Tiger Shark running as good as new was wonderful. My pool is crystal clear.
Fit perfectly on our bubbler lightv
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.
