    SWCG and the vinyl liner pool

    Folks,
    I'm in the proccess of researching pool options and interviewing builders.

    I'm still not decided if i will be going gunite or vinyl, but one open concern that i have (through what i've been reading) is a potential long term issue with using salt in a vinyl liner pool. The concern i've been reading about is a potential of saltwater vapor getting behind the liner and attacking the metal panels of the pool, eventually destroying the structure of the pool. I would think this wouldn't be an issue withe the gunite pool, but seems like a real possibilty on the vinyl liner pool.

    Any thoughts/experrience on this?

    Also, (so i don't have to create a separate thread), along the same lines, has anyone had any issues with SWCG causing issues to the automatic cover? I will more then likely be doing an auto cover, but again have the concern with salt.

    Thanks,
    Alex

    SWGs are just fine with vinyl liner pools.

    There are occasional reports of problems with SWGs and automatic covers with aluminum frames.

    SWGs will cause a metal wall to rust if, and this is a big if, you have a leak in the vinyl. Ground water is more of a concern to cause the metal wall to rust. We took delivery off a new wall kit and as we took it off the truck the panels were already showing surface rust. Now on the auto cover get a stainless steel mechanism and you should be fine.

    All chlorine pools have salt in them. It a byproduct of most chlorine sources. A swg pool has only slightly higher salt content than a typical non swg pool, especially after the 1st year of use.

    Re: SWCG and the vinyl liner pool

    Thank you for the feedback guys, i'm starting to lean towards a gunite pool, so the liner would be a non-issue. I'm planning to call Zodiac and ask about any potential issues (as well as warrany issues) with the Coverpools cover and SWCG.

    FWIW, I have a SWCG and vinyl liner pool with poured concrete walls. No rusty panel worries

    FYI I have a vinyl pool but the structure is all gunite (no additional charge vs steel walls).
