Swimline 4' Single Chamber Water Tube, Blue, In Ground Winter Cover Weight
The safe way to hold a winter cover down.
The Swimline 4' Single Chamber Water Tube, Blue, part VWT4, is a vinyl water bag that lays on the deck along the edge of a solid in ground winter cover and keeps wind from getting underneath, stocked under SKU PST-VWT4. Water tubes are what the cover was designed to be held down with, since a tube that shifts cannot chip coping or tear a liner the way a brick, block, or paver can. Fill it to roughly three quarters, not to the cap, because the water inside expands when it freezes and a full tube splits. Buy enough to run the tubes end to end with no gaps.

How full should I fill a water tube?
About three quarters. Leave air space so the water can expand when it freezes. Topping a tube off to the cap is the fastest way to find yourself buying replacements in March.
What is the difference between a single and a double chamber tube?
A double chamber tube is two sealed compartments in one bag, so a puncture on one side still leaves the other side full and the cover weighted. A single chamber tube empties completely.
Should I use a corner tube?
On a rectangular pool, yes. A short corner unit sits into the corner where a long straight tube leaves a gap, and gaps are exactly where winter wind lifts the cover.

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.
