I just replaced the liner in my above ground pool and I didn’t make a very good job of it. It felt really uncomfortable underfoot, like I was standing on pebbles. I’m was concerned that this would damage the new liner and I’d be back to square one so I wanted to see if I could find a solution without having to drain out all the water and reinstall it. However, after extensive research I couldn’t find a simple solution. It seems that if there are just a few small wrinkles it’s OK to just live with them although they’ll never go away and you take the risk, if you use an automatic cleaner, that the head will eventually wear through the ridge of the crease and cause a leak. However, my pool liner’s wrinkles were too large to take the risk so I had to drain the pool and start again. I wish I’d spent more time in preparation. There’s plenty of information around if only I’d bothered to look for it!

Is a thicker swimming pool liner better than a thinner one?

Liners come in different sizes, to fit your pool, and in a variety of thicknesses. There’s a common myth that a thicker liner is more subject to tearing away from the swimming pool wall since it is heavier. However, this is not true. It is the weight of the water that causes stress on the liner and not the weight of the liner itself.  As long as it’s fitted properly there’s no reason for it to tear away from the pool’s sides. So it’s usually advisable to go for a thicker liner that is more durable and commonly comes with a longer warranty. Also, to extends it life, make sure the water level doesn’t get too low and you dont’ use excessive cholrine.
