Your pump is allowed to suck air, lose prime and without water circulating through it becomes hot. Once the temperature reaches the melting point of the plastic pieces inside the pump is damaged.
No you just have to get the water level below the skimmer after that you should have no trouble making repairs.
when your water level is about 6 inches below the item. when your water level is about 6 inches below the item.
It won't work as a skimmer if your water level is above the skimmer. If you watch how the skimmer works, the water is pulled in over the skimmer door and it won't "skim" the floating debris off the surface of the water if the water level covers the entire opening, your skimmer will just suck in water that is below the surface. If you keep the water level so it's at least below the opening an inch or so, you should be o.k. If you've recently had alot of rain, you may need to drain some water out of the pool so your skimmers function properly.
Drain the pool until the water level reaches two inches below the skimmer faceplate , remove the face plate using a screwdriver , remove the faceplate and skimmer , then replace the gasket and attach the skimmer and then the faceplate
I believe that they need to be at least below the bottom of the skimmer so that, if the waterline were to drop below the bottom of the skimmer, the returns would not run dry. In my pool they are about 15-18" below the usual water level.
Ideally you show keep your water level between one third and one half the way up the opening of the skimmer. This is the level at which the skimmer(s) operate most efficiently.
If the water level is deeper than 1/2 inch below the top of the skimmer(s) - it's too high.
You don't have to close anything. Just use a short piece of hose or tubing to siphon enough water out to drop the level at least an inch below the skimmer box and inlet port. To siphon, place the entire length of hose into the pool and fill up, place your finger over one end and hang that end out of the pool, leaving the other end in the water. Gravity will take care of the rest.
Yes just keep in mind that the water level in most winterised pools is below the skimmer outlet.
Could be the water level of the pool is too low. Top up with the hose into the skimmer basket.
The water level needs to be maintained at the middle of the skimmer opening or center of the tile line.
Not necessarily When this happens you could get a water tank to take up the water until later when the pool needs topping up. putting a floating pool skimmer in would mean that skimming would always be maintained properly regardless of water levels.
