Most likely your skimmer has two holes being either for pumping from the bottom or the rear depending on how the Plumbing is configured. Have a look at your pump with the vacuum hose plugged in. Is the basket got air trapped in the top? Unplug the hose does the air go away? Chances are if this is the case the seal in your pump needs replacing.
Attach the hose to the side skimmer basket with a special plastic adaptor that fits in your size skimmer. Types of skimmers: Brands: Purex, Anthony, American Products, Pentair, Hayward are major names. Hum, not inside the skimmer basket but under it. There you will find either a disc type object much like a flying saucer. Then under that there will be 2 holes. The one, if you are looking down into the skimmer from the deck side of the pool, to back side of the skimmer - 0 0 < that one - closest to you is the suction part of the skimmer. Your hose is pushed into this hole after filling the hose with water. The "adapter" is another type skimmer as stated above that you can rotate to the left or right to achieve optimum skimmer suction. With a single hole skimmer - that hole is the suction for the vac. You just have to plug the second skimmer if you have one. Still, there is another with a hole in the side wall of the skimmer near the bottom of the skimmer. This is also the vac hole. With it you plug yoyr vac into it and then close a valve that controls the main drain. You have to remember when you are finished vacing pool you then open the main drain valve. The latter one is a quite old system made by or used by Anthony Pools. k
I can't comprehend how suction would work in a vacuum :-) Black Holes' use their gravitational force to pull matter into them.
A suction flask is the glass bottle used to hold the liquid sucked from the throat of an aspirating patient. It is a bottle with a rubber stopper in the top. The stopper has two holes in it. Into each of these holes is placed a glass (or plastic) tube. There is a long tube that extends to, or almost to, the bottom of the flask (Jar or bottle). The other tube is short and extends only to the bottom of the rubber stopper. The short tube is connected to a vacuum source, which creates a low pressure inside the bottle. The longer tube is connected to a device that can be put into the mouth and throat of a patient. Any liquid in the mouth and throat is sucked into the jar. Because it is heavier than air the liquid will settle in the bottom of the suction flask. Because the tube connected to the vacuum source is at the top of the suction flask liquid will not be sucked in the suction source. Usually there is a filter and device between the suction flask and the vacuum source to prevent any extraneous liquid from entering the vacuum source. Suction flasks have been replaced, nowadays, with plastic containers.
Black holes are some of the strangest and most mysterious objects in the universe. Suction is caused by pulling something into a vacuum, which the massive magnitude like the tornados on earth.
Possible causes: holes, cracks in vac hose - bad lid o-ring on pump - pump seal leaking - cracked pump lid or housing - pump basket full of debris - cracked or broken plumbing between the pump and the skimmer/vac hose connector.

On the pool I take care of, before the pump (suction side) there is a large 3 position valve. To the left is bottom drain, middle is all 3 and to the right is the 2 skimmer baskets. You will have to check to see which one controls which on your pool but is simple to check, turn all the way one way and stick your hand into one of the skimmer baskets and feel for suction.Answ:: Most newer pools have a "valve assy." of sorts at the bottom of the skimmer. It is either made of plastic or brass. This rotates in one direction to either increase or decrease the suction at the skimmer. It really does not totally shut off the main drain.Other type skimmers have a system that uses a "float valve" at the bottom of the skimmer. Removing this unit from the skimmer will reveal two holes at the bottom of the skimmer. Looking down into the skimmer from the deck side of the pool ~ the hole closest to you would be the direct link to the pump. This is the port in which you would connect the vac hose. The other one is connected to the main drain and all go back to the pump from the bottom of the skimmer. The "float's" purpose is to prevent the skimmer from sucking air in the event the water level got too low. It has a floating stopper inside.If your set up has only one port at the bottom of the skimmer then you most likely have a brass or PVC valve situated just before the pump inlet. Sometimes there are multiple valves and are usually not marked as to what they control. You just have to work with a partner to find out which one does what and where.k
Yes and no. One hole, the one to the rear of the skimmer goes directly to the pump. This also acts as your vacuum hose port for vacuuming the pool. The other comes up from the main drain. Covering both of those ports should be a float valve type of an assembly. One of the purposes of the float valve is that when and if the water level gets too low in the pool then the float in the valve assy. seats and will then let water flow in to the pump directly from the main drain. Hope this is satisfactory. Ken
Actually, they aren't a bad thing to remove all together. Skimmer flaps are a notorious place for algae, especially black or mustard, and bacteria to hide and grow, which makes reoccurance terribly probable. Removing them all together will not harm the performance of your pool. I beg to differ with the answer above - The skimmer works because the water jets create a flow which pushes the water past the skimmer. The skimmer is pulling water down which causes debris on the top of the water to get caught in the basket. The skimmer flap(s) limits the amount of water being sucked in by the skimmer causing more suction and making the skimmer more efficient. It is important for the skimmer doors, or "weirs" as they are called, to be in place for your skimmer to work properly. Try it for yourself. With the skimmer running, place your hand, a brick or some other obstruction where the skimmer door should be. Restrict the water flow a bit in some way. You will see a much larger volume of water being sucked into the skimmer than with no door at all. If you already have a flap or wier in place, do the reverse. With the skimmer running, hold the door completely open and see hose the flow virtually ceases. Replacement weirs or flaps can easily be found at your pool store. Just take your old one with you or measure the opening where it should sit. Little pegs on the sides of the replacements are spring loaded to keep it properly situated so it is very important that the new weir be exactly where you want it before pulling the pins securing the pegs. I hope this has helped!
No you fool, it's gravity.
First off, you'll need a vacuum hose. I usually put the small end over the jet and fill the hose with water. After the hose is full put the large end in the skimmer. Place your vacuum head in the pool, attach the hose to it, now you're ready to vacuum.
Technically, space is not a complete vacuum. There is always a very low-density amount of interstellar gas and dust. The idea of black holes being like 'vacuums in space' is a crude simplification created so that young children can have a basic concept of them. Black holes pull material in via gravity, not suction.
