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.
Not necessary. The main drain just sends water down the city drains, filtering just pumps the water from the scuppers, through the filter and back into the pool. The cycling is fine until you want to drain the pool for some reason.
Use the main drain when backwashing, rinsing, or vacuuming. Use skimmer all other times to filter.
It should not have water in it, especially if freezing weather is expected. Drain the pool to below skimmer line and drain the filter and filtration equipment.
You only use the skimmer/s
Depends how the pool was plummed. If you have a dedicated main drain line, or you share a main drain line and a skimmer line. Both are suction lines to the pump,meaning they will go into the front of the pump. If you have several valves on the front of the pump, and hopefully they are labeled you could try to shut all of them except the main drain and use what is called a drain king. It hooks to a waterhose and swells inside the pipe forcing water in the opposite direction. If you dont have any valves on the front of the pump ,chances are you share suction with the skimmer. check the inside bottom of the skimmer. Main drain may be plummed to skimmer bottom.
try a shop vack drain the pond/pool down to the bottom of the front of the skimmer then turn the pump for 25 sec till you see the water drop in the line let it dry a bit then shop vack it
its the drain line for water to drain
You can buy a devise called a Jeanie Jet and it connects to your water hose. Take the lid off your pump and insert it into the front of the pump going back to the skimmer. You then turn on the water and it should blow out the line and unclog it. What comes out of that line will come out into the skimmer so watch for it.
i have to drain out 4800 cusec of water
The water level needs to be maintained at the middle of the skimmer opening or center of the tile line.
Because both sides of your sink are connected to a common drain line, and the common drain line is slow.
Drain line is clogged.
Yes, be sure to pipe floor drain line properly into water closet piping.
The easiest, and cheapest way is to turn the suction valves off to everything but the suspected skimmer, if your pump bowl stays full of water, it is fine, if it automatically looses suction, then you have either a break or a blockage. Put a plumbers helper in the suction side of your pump pot and blow whatever blockage you have towards the skimmer. A snake will not work here because your skimmer actually has vacuum (negative) pressure unlike a sewer line,which is not a pressurized line. tritonunderwater.com
You should boost the chlorine. level somewhat. I would not drain unless there is another storm coming. Why waste the water? For that mater you can avoid having to drain the pool altogether by put in in a floating pool skimmer no mater how high the water gets it works a 1,000 percent better then the existing static skimmer A: hmmm, I don't quite understand just how a floating skimmer will prevent the water from overflowing at the coping. Skimmers have nothing to do with removing excess water from the pool! In the answer above, you have got to mean add an overflow pipe at the water line and have it drain to the street or somewhere off the property. Boosting the chlorine answer is ok but in addition I would run the filter/pump to clear out the contaminants that the rain would add and that could also be from the splash of rain on the deck or off the roof or rain gutters. Only drain the water off if the storm is a strong one with lots of rain or if there is another rain storm coming in soon. k
First of all you cut the concrete 2 paralell cuts from pool edge toward the pool equipment, jack hammer out concrete remove old skimmer and coping , plaster, etc, trench out from skimmer location to exist skimmer/drain line,set new skimmer in place plumbin to old skimmer line pour concrete around base of skimmer to set in place, wrap 1/2" rebar drilled and epoxyed into exist pool gunite, build form around skimmer and rebar, pour form with rapid set mortar, pour final layer of finish concrete, replace coping repair plaster and voila you r done
