Thread: Freezing Question

    Freezing Question

    My pool is completed and filled as of last week. Our forecast for the next two days calls for night temps down to 29. What do I need to do? Daytime temps will be 50's. I have heard I can just run the pump but that won't work for my deck jets or I could have some really cool ice sculpture the next morning. Could I just tent the entire equipment pad and cover the deck jets with blankets? Is a few degrees below freezing something to freak out about because after spending months on the biggest DIY project I have ever done I AM FREAKED out.

    Re: Freezing Question

    Can you not run the pool without the deck jets on? That is what I would suggest and just put some blankets over the desk jet nozzles.

    But, putting a tent over the whole pad (maybe adding a light under it) would certainly not hurt ... although I am not sure the brief time it will be below 32 is even enough to worry about so hopefully someone else will chime in.

    What do I need to do?
    Nothing. That's not cold enough long enough. Running the pump all night will probably make you feel more secure for a couple of bucks.

    Re: Freezing Question

    Ditto to Dave,

    We regularly get down to 25 F in the winter here but never more than about 6-8 hours and I never use freeze protection nor run the pump at night. Knowing a little about the physics of freezing and add to that a few experiments and it takes over 12 hours for a 2" PVC pipe to freeze solid and that is at 0 F. At 29F it would take well over a day or two. Heater pipes might freeze a little faster but they are deep within the housing of the heater which helps with radiative losses. BTW, I have a heater too.
