Because there is no main drain on most aboveground pools, you will only be able to lower the water to the bottom of the intake or skimmer, using your aboveground pool filter system. To drain an aboveground pools, either a). Use small submersible electric pump and garden hose, or b).
Main drains are not required in an inground swimming pool, however, they are strongly recommended and can be extremely useful in some circumstances. The advantages of main drains are to give you the ability to drain the water from your pool without the use of a sump pump.
In a safe pool, there are always multiple main drains as well as several skimmer drains, so if somebody or something blocks one drain, the pumping system will pull water from one of the other drains.
All you need is a medium-size water or vacuum pump. Unroll the pump's intake hose so that it reaches the center of the pool (or as close to it as possible), and submerge it in the pool. Place the outlet hose so the exiting water doesn't flood the area, but drains off away from the pool.
Submerge the pool pump's intake hose under the water, as close to the center of the swimming pool as possible. Choose a space on your property for the pump's outlet hose to drain. This area should be away from the pool and the ground should be level to avoid flooding.
Flooding Your Grass Is Not A Good Idea
The problem with draining your pool in the yard, if permitted by your local water regulatory laws, is that it will quickly reach its saturation level and increase the risk of flooding your lawn, drowning the roots of your grass, and attracting mosquitoes.
If you can pump around 30 GPM (gallons per minute), which is also equivalent to 1800 GPH (gallons per hour), it should take you 2.78 hours or 2 hours and 46 minutes to drain your pool using a hose.
The main drain for a pool is a suction port that should be located at the deepest point on the pool floor. A main drain is responsible for aiding in the circulation and filtration of the pool water. Having a properly working and dedicated main drain line can also allow you to fully drain your pool if necessary.
A pool's so-called main drain is not actually a drain; that is, it is not used to drain the pool. Instead, it is an outlet, housing a pipe that runs to the pump, which sucks water through a skimmer, then through a filter, then through a heater (if you have one), and then back to the pool via multiple inlets.
Swimming pool main drains don't actually drain anything. Rather, a swimming pool's main drain, if it has one, is a suction device. A pump is located underneath or near a swimming pool equipped with a main drain and it's used to pull water down into the drain.
When constructing a new swimming pool, if you are going to use a main drain it is required that you use two. This is due to safety regulations to help prevent Main Trap Entrapment. Main drain entrapment occurs when the suction is so great through a single main drain that a person can become stuck on or in the drain.
While you may think the best thing to do to prepare for winter is to drain the pool, a vinyl-lined pool should not be drained under regular circumstances. Since the water secures it to the pool, draining it can cause the liner to lose elasticity. The liner can shrink causing tears and rips upon refilling.
No matter what kind of pool you have, it's very important to have a properly functioning pool skimmer. Without it, you could wind up with a less beautiful pool, improper cleaning and an overworked pump.
Put one end of your garden hose inside the port. Thread the hose to the back of your house. Attach the other end of the garden hose to a submersion pump and place the hose and pump in the deepest area of your pool, near the drain. The pool will begin to drain.
Submerged one end of the hose inside of the pool, close to the centre. Lay the other end of the hose lower than pool water, and leave it in the location where you want to release all the water. The water flow should then reverse and the pool will begin to drain.
Locate the Drain Valve
The drain valve is located on the outside of the pool. Run a garden hose out, with the female end near the drain valve. Connect the other end to a sprinkler, and water your lawn or garden (if pH is good and chlorine low). Remove the cap.
Start a siphon with your vacuum hose / head on the pole, or a siphon using garden hose(s). Pumping the water far from the pool's edge is best, so as not to oversaturate the soil supporting the pool. Monitor the draining and the discharge. Siphoning can take days, a small submersible pump will take 6-12 hrs.
Although you normally clean your pool with a manual pool vacuum or a vacuum device often called a "creepy crawler,'' you can clean it with a standard wet/dry shop vac. The disadvantage to this method is it takes a long time because you have to repeatedly empty the water from the shop vac.
The first choice for draining swimming pool water should be to drain pool water into the sanitary sewer. In-ground pools typically have a sanitary sewer drainage inlet near the pool equipment. Pools and spas not plumbed with a sanitary sewer drainage inlet can be drained to a sanitary sewer line plumbed to the home.
Turn the filter off (or unplug it) and set it to Waste. Shut off your skimmer and open your pool's main drain. Turn your filter on and the water will start to pump through your backwash hose. Allow the water to drain.
Simply stop adding chlorine to your uncovered pool and wait. Sunlight will help to naturally dissipate the chlorine within 10 days. During that time, use a swimming pool test kit to measure chlorine. Chemically dechlorinate the pool water.
If an individual empties their pool water on their lawn, will it end up killing the turf? In most cases very little to no damage has been seen in these situations. Turf can endure higher chlorine levels than other landscape plants such as trees, shrubs, and ornamentals.
