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.
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
No. You cannot use the main drain to lower the water level below the skimmer. This is because the main drain is not really a drain. It only connects right back to the 3 port valve in the skimmer.
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.
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.
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.
you can back wash the pool and drain to proper level Throw a pool party with lots of energetic kids.
Yes you can. Drop the waterline in the pool below skimmer level, dig a whole around your skimmer to gain access. Unscrew the skimmer faceplate and remove it as well the old gasket. You also have to remove the second gasket between liner and wall. Detach the pipe(s) from the skimmer. Now install the new skimmer by attaching the pipe(s) to the skimmer put new gaskets in place screw the faceplate back on and you're done. Don't forget to fill your hole again and put water back in the pool to the appropriate level. ;-) Jens Poseidon Pool Services, Dunrobin, ON
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.
Yes just keep in mind that the water level in most winterised pools is below the skimmer outlet.
Using a typical 1/4" per foot fall (slope) on a 1 1/2" drain, such as a sink drain, the vent must be within 6 feet of the trap to avoid falling below the drain level, and thereby not functioning as a vent.
The toilet flange is usually above the floor level. You would have to cut it off the drain pipe and cap it. How you do this depends on what type of pipe the drain is made of. Even if the drain should be below the floor level, you have to seal the drain or sewer gas will come up from the drain.
