We have a 25,000 gallon in ground pool and we drop ours about a foot below the skimmer and then blow out all the hoses and add antifreeze for underground hoses. My husband has done this for 12 years.

Or - you can get whats called a gizmo (I think) - and on each return valve screw in a PVC elbow with enough pipe connected to get it above the water line. When you do this you don't have to lower the pool water at all. The gizmo and elbows on the outlets let you blow the lines clear - without lowering the water. And the gizmo is softer plastic so it will absorb the expansion of the frozen ice in the skimmer and prevent damage there as well. In addition to the gizmo - I stick an empty plastic jug from the antifreeze used to keep the lines from freezing in the throat of the skimmer and also next to the gizmo - to provide exrta protection (keep the caps on so they don't fill with water - you want them to absorb the expandind freezing ice as well.

Once the lines are all blown - I insert a rubber stopper that has a screw and washer (basically so you can tighten it) onto each of the PVC's connected to the outlets.

You should remove the antifreeze with a shop vac if possible, antifreeze will not hurt the water, but is just one more thing in the water that you do not need to be there.


Should you empty the pool and turn off the pump during the winter months?

Absoltutely not. The pressure underground will lift and crack your pool. You should lower the water to below the skimmers and do a full pool closing for the pipe system. If you don't know how to get the water out of the pipes and filter you must call a professional. Most owners do it themselves but be sure to learn the proper technique.


A swimming-pool worker wants the pool's pH to be 7.2. She comes by to test the water and finds that the pH is 9.2. What should she do to correct this situation?

To lower the pH from 9.2 to 7.2, the worker should add an acid, such as muriatic acid or pH decreaser, to the pool water. She should follow the manufacturer's instructions on the product to gradually lower the pH level, frequently testing the water until it reaches the desired pH of 7.2.


Does the skimmer flap need to be removed when closing pool for winter?

Yes, the skimmer flap should be removed when closing a pool for winter. Removing it helps prevent water from freezing and causing damage to the skimmer and plumbing lines. Additionally, it allows for proper water drainage, reducing the risk of ice expansion that could crack the skimmer. Always ensure the skimmer is properly winterized to protect your pool equipment.


How long does it normally take to drain the water from the pump when closing an in ground pool for the winter?

Draining the water from the "pump" (I'm assuming you mean the filter) should only take a few minutes. How long it would take to drain the water in the pool down to the winterization level would depend on the size of your pool and the pump you are using.

How do you lower pool water below the skimmer?

To lower pool water below the skimmer, you can use a submersible pump or a garden hose to siphon water out. If using a pump, place it in the shallow end of the pool and let it run until the water level drops below the skimmer. Alternatively, you can create a siphon by placing one end of a hose in the pool and the other end at a lower elevation, then filling the hose with water and letting gravity do the work. Always ensure to monitor the water level to avoid damaging the skimmer or pool equipment.
