GLI Standard Duty 8' Double Chamber Water Tube, Black, In Ground Winter Cover Weight
Holds the cover down without gouging the liner.
The GLI standard duty 8' Double Chamber Water Tube, Black, part 500008WTDBLK, is a vinyl water bag that lays on the deck and pins the edge of a solid in ground winter cover, stocked under SKU PST-500008WTDBLK. Water tubes are the right way to weight a winter cover, because unlike bricks, blocks, or sandbags they cannot chip the coping or tear the liner if they slide in. This one is a double chamber tube, so a puncture in one side still leaves the other side full and the cover held. Fill each chamber to roughly three quarters so the water has room to expand when it freezes.

How full should a water tube be?
About three quarters. Water expands as it freezes, and a tube filled to the cap has nowhere to put that expansion, so the seam or the cap end fails over the winter.
How many tubes do I need?
Enough to run end to end around the whole cover with no gaps. Add up the perimeter of your pool in feet and divide by the tube length. Gaps are where wind gets under the cover.
Why a water tube instead of bricks or blocks?
Water tubes are soft. A block or brick that slides off the deck can chip coping, tear a solid cover, or drop through and damage the liner. A tube just slumps and stays put.

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.
