Usually there is a plug for that. If not, you can have a professional come and use the vacuum thing. I recommend that you use a professional to drain your pool for you. The cost will typically range from $50-$100. Make sure that the pool professional opens the hydrostatic release plug when they drain it and make sure that they drain the water into your main sewer drain in the front yard. If they drain it into the drain coming out of the house in the back or side yard it can clog up your piping and end up draining all 25,000 gallons into your kitchen. If they just drain it into the street you can be fined. If you insist on doing it yourself you can rent a sump pump and the hose from a place like Home Depot for about $50 and follow the directions above. Make sure you turn off your pool supplies before you drain the water.
Installing swimming pool lights is very difficult. It requires you to drain the water from the pool, and then to drill a place to mount the swimming pool lights.
You don't drain an inground swimming pool, unless you are trained to do so. Doing it alone or even with assistance is extremely dangerous. Save yourself some trouble and go contact a local and trained swimming pool cleaning service.
simple drain a bit of it
You drain the water then plaster the walls from inside
Once a week really
you could drain the pool, but if you don't want to drain your pool, you could get a pool skimmer and get all of the leaches out of your pool and then carry the leaches to a near by sewer, or a murky pond/lake/river.
There are a number of different methods you could use to keep ducks away from your swimming pool. You could for example cover or drain your pool when you are not using it.
If its not connected through the skimmer I imagine it's there to empty it. hmmm, on the above. The main drain in pools is for circulating the lower part of the pool and is not intended to drain the pool as in a bath tub.
Yep it so is
I, myself, would drain it - especially after a natural disaster.
