Unknown pool part

[lilpam14]

HI I would love to post a pic of a part I found in with the pool supplies I acquired but it tells me the file is to big. Hoping if I can describe it good enough someone will tel me what it is and its purpose.
It is clear, hard, acrylic plastic, reminds me of clear PVC. It is in the shape of a right angle/elbow. On one end it has a u shaped area that looks as if the vac. hose attaches there. Inside of it there is a mechanism with a tight spring and black plastic disc that occludes anything from getting through it to the other end of the elbow. ?????? :?

Some type of check valve?

Reduce the size of the picture in Paint or picture manager. Or post it on Photobucket and post the link.

Sounds like a check valve to me as well.

OK got it, maybe I can get pics up here now. I know it will make it much easier to ask you all questions.
So why would they have a check valve but not have it on anywhere? Do they have some that you take on or off?

A picture will definitely be worth a thousand words in this case.

Without a picture, I'm betting it's a flow indicator for a suction side diaphragm cleaner - water flowing past the gate gives you an indication of too low / medium / too high flow for the cleaner's bumping action.....

Mine got stuck halfway up a wall and sounded like a bass drum, until a neighbor called me at 0130 hrs to complain..........

That was my guess as well. You would only use it when running the cleaner. It mounts in the skimmer bottom and the cleaner hose would attach to the other end and go out the skimmer door. In theory they work as describerd, some also have a hole in the side with a spring loaded door in it so that if the suction is too high the door opens and allows the unit to draw water from the skimmer rather than all through the cleaner diaphragm.

Mine is touchy as well. too low and it just lays there. Too high and it climbs out of the water. The "just right" pressure is in a small range.

I believe this is what you are describing.

It is a vacuum gauge that comes with a Navigator to set it up.
You plug it into the last hose, then attach it little U piece back to the hose near the wall outlet.
This allows you to run back and forth to adjust a valve and get the ideal flow prior to plugging in your vac.

@ just a PB You are exactly right. That is the exact piece I have. THANKS especially since I never got around to getting a pic posted.
Thanks everyone
