    Winterizing in Gulf Coast Texas

    I'm from Michigan so I have this idea in my head that every pool has to be closed for the winter. I'm not sure that's true here in Texas where it doesn't get that cold.

    I just bought this house, this is the first winter. Do I need a pool cover? What do I do all winter long?

    I'd love to hear what you do.

    Re: Winterizing in Gulf Coast Texas

    I do nothing... That is also what my wife keeps telling me...

    When it gets cold and the SWG turns off, I chlorinate with liquid chlorine or bleach. Other than that, I maintain the pool just like I was going to swim in it.

    No cover or draining, no nothing..

    Well, I'm in Tucson, AZ which is actually a higher latitude than where you are. I suspect other Houston-area pool owners will chime in but the advice will likely be this - we don't close pools this far south. Pools down here just stay open all year long. When the winter comes, you can certainly cover it with a bubble cover, but there is no need to winterize, drain, tightly cover, etc. Just make sure your pool equipment has some kind of freeze protection circuit so that when overnight temperaryres go below freezing, the water circulates. If you don't have something to do that automatically, then you'll just have to remember to do it yourself. As far as chemistry goes, once the water temp drops below 60F, algae growth rates are practically non-existent and so chlorine demand goes way down. You'll find you can for very long stretches without having to add any chlorine at all.

    That's about much easier to own a pool when you don't have to wrap it up for winter....

    Re: Winterizing in Gulf Coast Texas

    Hi! Welcome to the Texas Gulf Coast! I use a winter cover to keep my pool from getting knee deep in oak leaves, when I actually have a winter cover! We rarely have prolonged, hard freezes where you need to worry about bursting the pipes to the pool. Most of the time your pool water won't drop far below 50 degrees and the frost line here is maybe 6" so your buried pipes are well protected. If we do get a hard freeze warning you will hear about it for days in advance! Running the pump during the freeze hours overnight should be enough to protect the above ground runs of plumbing. If you want a little extra insurance you can treat it like a plant and wrap the pipes in an old blanket.

    You can choose to keep the pool up and running on a regular schedule or you can clear any existing algae, raise the FC to slam level, cover the pool and give it a rest. You don't need to drain below the returns, since if we do get a freeze warning you will want to be able to run the pump overnight. As long as you wait until the water is around 50-60 degrees to close and open before it hits 70 degrees you shouldn't have any problems.

    Re: Winterizing in Gulf Coast Texas

    New owner in ATL area. Just bought a AutoPilot Total Control (same basic salt water generator as Pool Pilot Digital). It will automatically adjust the generation based upon water temperature. And if you use it to control the pump (turn on and off), it can automatically run freeze prevention. I can not currently comment on how well it does these yet, as I will find out this winter, but those are a couple of the reasons I purchased the unit to replace the original one the PB installed.

    Re: Winterizing in Gulf Coast Texas

    I'm in Houston and I do not fact I occasionally heat it and swim!

    I keep my FC / CYA balance as I do in the dead of summer except I don't have to replenish as much water since there's less evaporation in the winter. It's nice to have a pool in the winter here.

    In my experience the majority of pool owners in our region keep their pools open 12 months per year, but just go into a semi dormant maintenance schedule during the colder weather. Some cover their pools, but they tend to be in the minority.
