It can be drained indefinitely as long as you have some way to ensure pressure relief from ground water. I plaster pools for a living (8 yrs)and we also acid wash. All you need to do is open up the hydrostat plug in the floor (preferably in the deepest part of your pool, ie. the bowl by the drains). If you don't have these plugs, please don't leave empty to long as your pool could float from the ground. Even without these though you are still fine to do maintenance such as a quick acid wash.
Generally, one must wait at least a half an hour before you drain the pool.
Well, the question really seems to be asking is how long do you wait before starting to draining your pool before you start work on the tiles. And/or I want to acid wash a pool -- how long can I wait before I start to drain the pool?
Maybe the question should state: I want to drain my pool to work on the tiles at the tile line and then acid wash the plaster -- How long can I leave it empty and dry before I have without substantial problems?
It may be possible to go up to 4 to 7 days before the integrity of the plaster is compromised depending on location and weather. Extreme heat and sun are tough and non-forgiving on dry plaster.
kFrom A Pool ContractorYou can drain a gunite pool any time after 30 days past completing the interior surface process. Once the concrete has cured for 30 days you can drain the pool for any work that it will need. The newer in age the plaster is, the more likely it will be to staining, especially at the waterline. There is concern for hydrostatic pressure to lift the pool out of the ground should you live in an area with a high water table. Remove the hydrostatic relief valve from the bottom of the main drain and discard. You will replace this with a new relief valve after the renovation.
On a day by day basis you will want to wash down the pool plaster. If you leave construction debris, mortar and slurry on the plaster you will cause staining and pitting. It is preferable to have the pool be dry for as little time as possible as the plaster finish is likely to begin crazing and possibly separating should it be exposed to extreme heat. Freezing temperatures are also very hard on the interior surface of the pool.
Because the pool plaster will be at risk during this renovation, it is very common to renovate the tile band and then replaster the interior surface of the pool both during the same renovation. This will ensure the plaster is perfect at the end of your project.
No, because gunite will not dry if it is constantly being mixed with water. Drain your pool first.
Best not to empty a gunite pool, period. Having the pool surface exposed to air and temperature chanfes and drying will result in cracking.
put a pump in it and drain it. dont try if its anything other than a gunite pool. Pools are equipped with pumps already. If you have a main drain on the bottom, just set the pump to pull only from the drain, and set the spider valve to waste.
Fuel filter is above fuel tank.The fuel tank must be slightly lowered. That is why there is a drain plug to drain fuel before doing this job.
Well, you don't have to do this... However if you enjoy doing this, go ahead. You just don't have to drain it! You can but I wouldn't recomend doing it simply because you only have a limited amount of recharges until the battery will die really quickly.
your main concern would be the weather,if you want to drain and repair pool pick the dryest time of the year for your area as it will only pop up if it rains heavy.if you intend to leave it empty well then you would have to put holes in the gunite
With the onset of the cold weather, you will need to winterize your gunite pool. Backwash the pool filter. Detach the pump and filter to drain any left over water. Drain the pool heater. Remove return jet fittings, the skimmer basket and pipes. Blow air through the system until bubbles appear in the water and cap off the fittings. Put an empty twenty ounce plastic bottle in the skimmer basket to compensate for freezing and thawing. Remove water from the main drain line and cap it. Remove ladders and floats. Lower the level of the water beneath the tile line.
When facing the front of the Mercury Mountaineer, the drain plug is on the lower left of the radiator. Place a bucket under the drain plug spigot before loosening to catch the coolant. To empty the radiator, turn the drain plug three-quarters of a turn. Tighten the drain plug before re-filling with coolant.
Roselia learn giga drain at 25 before evolve to roserade.

Use a snake and unclog the drain PROPERLY. Do it quick before everything is eaten away on the tub and drain.
It can drain either way, depending on the exact shape of the container, and any residual movement the water may have had before starting to drain it.

......before, but I would not recommend direct drain. The washing machine hose must extend up above the flood rim of the washing machine before entering the drain. If not, there is a possibility of sewage backing up into your washing machine.
You probably will get some coolant in the engine oil. It would be best to drain the radiator and block before disassembly.
Disconnect any lines which would interfere with the removal (you may want to drain the fluids before doing this), unbolt the head bolts, and lift.
Yes, as long as drain line is sized properly for toilet. 3" drain line would be minimum pipe size for toilet drain line to tie into.
You can drain them as long as you are sure there is no water underneath because if there is the pool will start to float in it if you dont have a hydrostatic valve in it, and if it does that its buggered. This rule apleis any where in the world, exept posibly in areas where there is permafrost.
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.
Never drain an inground pool, ever. The pressure from the gound water will either pop it out of the ground (with gunite or fiberglass), or cause the liner to pull off the walls and floors and float (vinyl). You need to make sure the ground water is pumped down before taking water out of the pool. Even if you did empty the pool down already and it "seems" okay, by the time all the snow melts in the spring, and the ground water rises, you could be royally screwed.
Most electric pumps have a guard at the bottom to prevent leaves and such from getting into the pump. Unfortunately, you need to have usually about 1/2" to 1" of water in the pool for the pump to work. I would suggest trying to drain the remaining water with a hose.
