the hydrostatic valve is only to equalize pressure of ground water to that of the pool the only time it does anything is when the water table becomes higher in the ground water than in the swimming pool . it doesn't connect to anything. it is simply to keep the pool shell from floating out of the ground

What is the device called that can alternate between the pool skimmer and the vacuum?

I think you are referring to a Jandy valve. The valve diverts water from the main drain to the skimmers. When vacuuming, turn the valve so it is pointing to the skimmer inlet pipe. OR It could also be called a diverter valve located at the bottom of the skimmer depending on the age of the skimmer. k


Can you use the main drain to lower the water level past the skimmer?

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.


How do you unclog a swimming pool drain pipe?

How do you know that the main drain is plugged? When was the last time that you back washed or cleaned the filter? If there is no flow at the main drain - check to see if a valve has been closed or adjust the variflow valve in the skimmer - located at the bottom of the skimmer- if you have that type of skimmer. Also check the pump basket - it may be full of debris.k


How to drain pool with main drains?

Unless the pool has a dedicated main drain line and a positive seal valve it is best to use a submersible pump. Most newer pools have the main drain line connected to the skimmer and there is a diverter valve in the bottom of the skimmer that regulates the ratio of main drain vs. skimmer suction. Once the water level drops below the skimmer throat the suction is usually lost. Check with your local codes and laws as some areas require draining into a sewer cleanout and other areas allow draining into the storm drain system as long as the chlorine has been allowed to dissipate and the pH is between 7 and 8.


How do you clean a bottom pool drain?

The drain - called main drain- is or should be connected with the skimmer plumbing and that goes to the pump. You should not have to clean the main drain unless you have a massive amount of debris. Main drains are routinely cleared using a CO2 tank and either a plug adapter or an inflatable canvas bag thingy the name of which escapes me at the moment. Place it in the front port of the skimmer if that is how it is plumbed and open the tank valve full blast. You will either clear the drain or the plug/canvas thingy will come shooting out of the skimmer so don't stick your face over it when opening the valve. If the pool has a separate main drain there will be at least 1 three port valve in front of the pump pot. With the valve pointed in the right direction put the CO2 tank hose with plug or canvas thingy into the suction line and let er rip.


How do you use the bottom drain in an in-ground pool?

Well, if you mean to drain the pool --- it is not a drain as in house plumbing -- the sink -- the tub. It is connected to the skimmer and that is connected to the pump. Your main drain is most likely 'working'. It does not nave to be a strong flow. Well, if you mean to drain the pool --- it is not a drain as in house plumbing -- the sink -- the tub.

How do you turn on and use the floor drain to filter and isolate the skimmer filters?

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


How can you figure out which valve on your filter system is the main drain?

If you look at the pipe that is going into the filter pump you will notice that it has a tee that is peceeded by two or three pipes comming up from the ground. Those will be from the skimmer, main drain, and if you have one from the cleaner. If you observe the flow of water in the skimmer then change the valve so there is no more water flowing that will be the one going to the main drain or cleaner. Repeat the process to eliminate which one is the cleaner. Which ever one is left is the main drain.


What is the Purpose of a main drain in a swimming pool?

If its not connected through the skimmer I imagine it's there to empty it. hmmm, on the above. The main drain in pools is for circulating the lower part of the pool and is not intended to drain the pool as in a bath tub.


Where do you attach the vacuum hose to vacuum the pool?

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


On a 3 way valve for inground swimming pool why does pressure decrease when on skimmer only but is ok when both skimmer and bottom position selected?

That piece of plumbing may have some blockage in it or there may be a restriction of some sort on that line. There may also be a leak in that side of the plumbing. Is there any air coming back to the pool when in this position? If so that is the cause. Fix the suction leak and try again. The 3 way may not be positioning completely over that port. Or it could be that the three way valve does not have the 3rd port open. If the 3 way is prior to the pump, then one port goes to the bottom of the skimmer, the other goes to one of the main drain ports. When your skimmer has reduced "suction" (not pressure) it is then the 3 way may be drawing from both skimmer and main drain at the same time. You only have "pressure" after the pump and at the filter. Before the pump then it is considered suction. Or the 3 way may be plumbed or labeled wrong. Also, in another instance, with the valve in the skimmer position - it could be drawing from more than one skimmer. I suspect the latter answer.


When adding stabilizer to a salt water pool is the backwash running while pouring in the stabilizer?

When adding stabilizer to a pool you should not have a backwash valve open. Stabilizer should be added directly into the skimmer basket and you should open the skimmer all the way and close off the main drains for 24 hours.
