    Vinyl liner - lifespan and 'loose' spots

    Howdy all,

    So I was walking around my pool today and felt a 'loose' spot on the floor. It kinda feels like there's air under the liner, but the air doesn't move around when I step on it, it just FEELS like that. Like the liner is loose, but just in that little spot. (if that makes any sense)

    Is this something I should be concerned about? I don't see any issues thus far, but if an issue is going to arise I guess I'd rather get ready for it than be surprised one day.

    Also, what's the typical lifespan of a vinyl liner? I just bought the house last year and I'm assuming the pool has been in the ground since the house was built in 2001.

    Thanks!

    That's most likely water under the liner you're feeling. I wouldn't worry too much about it. It's happened to mine and I've resigned to fixing it when the liner gets replaced.

    Thanks, Rambler. It does have a water-like feel to it, now that you say it that way.

    Any thoughts on the typical vinyl liner lifespan?

    Vinyl liner lifetime is somewhat variable. The average is probably around 8 to 12 years, but they can fail early or keep on going for quite a while depending on the situation.

    Ah! The ol' 'it depends' answer. Yep, that would make sense. But thanks for the general guidline. That at least lets me know I'm in the range and will probably have to look into one within the next 5 years or so.

    Much appreciated.

    Re: Vinyl liner - lifespan and 'loose' spots

    i have the same problem - in the shallow end of the pool there is an area about 3'x3' where liner feels a little soft. There are some wrinkles and i can push them around a bit. i've been chasing a leak and i was thinking it was somewhere around that area since it seems like i have some water under. i dye tested it all around and found nothing.

    i didn't notice that area being softer before, but now i'm about 8" lower in water than before - maybe it affected it. or maybe i just didn't notice it before.

    the liner is 11 years old and in a good shape.

    my vinyl liner is faded and looks bad. Its over 12 years old though. Anyone know what replacement cost is installed? I'm guessing ~$2k for an 18x36'

    Hi Diver,

    I don't think I have a leak, but it's something I'll certainly keep an eye out. I wonder if you may have a leak in the piping? Just a guess. Other people on this board with much bigger pool brains than I and can offer advice on how to track that down. I'd be interested to know, too.

    Cruzmisl, sounds like you've gotten the average time out of your liner. Thanks for posting it. I'd be interested to know what people say about the cost of liner replacement since I suspect I'll be facing it in the next few years or so myself.

    Long Island, NY its probably closer to $3,000 for a pool that size. A neighbor of mine just replaced their liner in a pool that size and I believe paid $2,700. That is for the liner and labor.

    I replaced mine about 2 years ago. I got the liner at cost cause I have a family member in the business.
    Just had to pay labor. I think I spent about $1,800...

    Re: Vinyl liner - lifespan and 'loose' spots

    Thanks for info, mitch. I'm in southern VA so I don't know if the costs are similar, but it gives me a ballpark.

    Family in the business, eh? Do they do road trips to VA? And do TFP members count as family?

    Re: Vinyl liner - lifespan and 'loose' spots

    My liner is 29 years old -- I've only had it for 3 years. This year it needed one small patch above the water line. However, I just got a price for replacing it -- $3k for just a replacement, but mine will need some sanding and painting (steel walls) and maybe some other repairs plus foam on the walls, so it will be closer to $4k. The vermiculite floor is still good, there's just some rust on the inside of the side walls. The guy told me that a lot of the old liners like mine (20mm, btw) lasted longer than the newer ones as they used different materials back then. Mine is light colored and has faded, but I'd lean towards getting a lighter patterned one again. The liners they use come in 20 or 28 mm.

    ETA: the above prices include saving all the water -- they'll pump it into portable pools and then will pump it right back into mine

    Wow! 29 years old. That's incredible. I seriously doubt mine'll make it that long. I'm in awe! But I'll try and get as much life out of it as I can!

    Re: Vinyl liner - lifespan and 'loose' spots

    I replaced my liner after 27 years. I probably could have gotten a few more years out of it but it was a light colored liner that had faded badly. The new darker liner has raised the pool temperature about 4 degrees F. My dealer told me that maintaining proper water chemistry is the secret to a long life. Thay had customers that had to replace liners after 5 years and others that lasted 30 years.
