Pool drain not working

[teckademic]

Basically we bought this house with a pool few years ago. I didn't really pay attention but now I think that the main drain in the bottom of the pool isn't connected to the pool pump. I installed a swg and accidentally poured too much salt in the deep end. With the pool pump running, I brushed the extra salt over the main drain to see if it would suck it and try to dissolve faster. What ended up happening was the salt just sat ontop of the drain and never moved and just piled up.

The pool has 1 main drain in the deep end, 2 skimmers and a connected spa with 2 drains. I attached a picture showing what each inlet pipe does.

Could the main drain be clogged? But wouldn't I have another main drain pvc going to the pump? I tried to dig down around the other pipes to see if they just capped it off for some reason.

What are my options?

Thanks for any feedback.

It's possible the one of the skimmers is a combination skimmer, and is plumbed to the main drain. Look under your skimmer baskets - is there one or two holes? This is how a combination skimmer is plumbed: http://blog.poolcenter.com/article.aspx?articleid=6327

ward1983 may be on to something.

If the floor is plumbed to one of the skimmers (which is likely), if you do not have a float diverter under the skimmer basket, you will not get any suction from the floor.

You have more investigating to do

Thanks for the tip. I just checked while 1 skimmer has 2 holes, 1 of the holes is plugged, while the other skimmer does have 2 holes.

I went ahead and order a Float Assembly with O-Ring Replacement,

That should do it ... the extra hole in the one skimmer has to be where the floor is tied it
