Liners & Covers

Q: What is the difference of all your liner types (Unibead/JHook/Beaded)?
Q: What is a Unibead Liner?
A: A unibead liner is a 2-in-1 liner that gives the customer the option to use the liner as a beaded liner or a J-Hook liner. A beaded liner requires a bead receiver while the J-Hook liner just hooks onto the wall of the pool. 

Q: How do I place the plain blue liner on my pool: Smooth shiny side down or dull textured side down?
A: We suggest the smooth shiny side up! When the dull textured side is up, it tends to collect extra dirt and debris. Of course though, it is completely up to your personal preference as both sides work sufficiently!

Q: Should the flap by the seam on the liner be facing up or down? 
A: This completely depends on how you have decided to install your liner (Shiny side vs. Dull side). The flap may be trimmed as desired, but will not be covered under warranty if you puncture the liner. 

Q: Why does my grass grow through the bottom of the liner, and would this be eligible under warranty?
A: Unfortunately, this is not covered under warranty. We can't control the growth of your grass, but we do suggest using a weed killer prior to installing the liner to avoid this issue. Please make sure that the weed killer is safe for vinyl.

Q: How do I find the leak in my liner?
A: When your pool is calm, drop food coloring into the pool and it will help you pinpoint where the leak is in the liner. 

Q: How do I install the Bead/Unibead liner so that it fits perfectly?
A: We suggest you center the liner an insert the beads at the 4 cardinal points of the pool (North, South, East & West). Then, insert the bead in between these points to get the best possible fit. 

Q: Do all rectangular liners have 90-degree corner?
A: No, they may have diagonal or radius corners. 

Q: How many pieces of coping strips do I typically need?
A: In order to calculate the correct # of strips, follow the below steps:
  1. Multiple your pool size by 3.14
  2. Round that # up to the nearest whole #
  3. Divide this final number by 2
Q: How much of a cove should I have?
A: There should be a 4"-5" cove.

Q: How are the liner seams sealed?
A: A very high pressure heat seals the liner seams. 

Q: How can I purchase a cover saver?

Q: What is the lowest suggested temperature for installing a liner?
A: We don't suggest installing your liner at any temperature below 65 degrees. Unfortunately, colder temperatures shrink and stiffen the liner, making it difficult to fit properly.

Q: What Gauge or Mil is a Swimline liner?
A: Unfortunately we do not market our items as gauge or mil, but we assure you that our patterns and styles are comparable to the thickness of all liners in the industry.

Q: Why doesn't my liner fit?
A: To determine the reason why your liner does not fit properly, please review the following:
(a) Is it too cold out? Vinyl will shrink and stiffen when the temperature is below 65 degrees. Please install the liner when it is 65 degrees or warmer, as the sun will soften the vinyl, making it easier to smooth folds and wrinkles. 
(b) Has the shape of the pool been altered from it's original form.
(c) There should be two inches of fine sand or foam under the pool liner with a 4"-5" cove inside the pool wall. 
(d) Your pool may not be level.
(e) The liner may have been installed unevenly. Please refer to the above question that suggests how to install the liner properly!

Q: I need to buy a liner, can you quote me a price?
A: Unfortunately we do not sell liners direct to consumers. 

Q: Can you tell me where I can get our liner?
A: We sell to hundreds of distributors and a quick easy online search, or local dealer, will land you our products! 

Q: How do I operate my Cover Saver (Item #5436)?
A: Check out some troubleshooting notes below & see Instructions here!
  • Check to see if hose is kinked or bent. If it is, it would impede water flow.
  • Make sure base of unit is centered in pool & be clear of leaves and/or debris;  which may block or slow down draining.
  • End of hose and siphon pump should be lower than unit when working to prime/create siphon action.
  • Valve should be in "ON" position (tightened) when in use. Turning valve to "OFF" loosened position will stop the flow of water. Adjusting the air pressure valve (image shown here) will also allow for more rapid compression/decompression of the primer bulb.
  • Water will not flow uphill.
  • Filling hose with water prior to using siphon pump will help siphon action to start more easily & quickly.
