How to adjust an American Standard dual flush valve

here are some tips on how to adjust an American Standard dual flush valve.

NOTE: @garycossar3577 notice when I placed the valve back on, I installed it incorrectly. The blue (low flush) needs to be on the left side.

Good to know it *can* be adjusted, but the essential (missing) info is whether higher value means more water (or less) per flush ?

Thanks for breaking this down, I have had this toilet since I moved into my condo 7 years ago and over the past year it’s presented me with issues with it not properly flushing. It was embarrassing and annoying trying to figure out why my toilet wouldn’t flush properly. Increased the flow of water to 4 and boom seems to be working fine.

Very good job! In my language (polish) i can't find solution for my problem because this is my first toilet with this system and i was in trouble... but you help me. Thank you! 😊

I think that some models are different - my mechanism looks identical but on the low flush adjustment the little blue tab is spring loaded and you push it in to allow adjustment. If you force it out as shown on this video you will break it.

how are you suppose to tell what number its suppose to be placed? thats the part i dont understand. how do you determine which number its suppose to be at?

[NahNoThankYou]

Fernando for the win! You saved our shit!

[johnhughes]

But you never say which is the higher or lower flush setting? Is number 1 minimum or maximum?

[garycossar]

You installed the flush valve incorrectly after your adjustment. The green button should be on the left.

Do you know what the part # is to replace the small milky white seal/gasket at the very bottom of this whole plastic assembly?

[therainbow]

The toilet seat cover was down when you flush the toilet. We didn't get to see how it flushes after you did the adjustment.

what do the values mean for both settings? A low number is less water flushed and a higher number would be more water? Do the numbers equate to litres? Same as a previous question, where did you get the settings for your cistern?

How do you control how much water is in the bottom of the stool not the tank?

[jhamm]

Is it lower the number, the longer the flush (more water used)?

So when you took the park off the color flush was on the left and when you put it back you put it in your right. Did you put it wrong

Good video, thanks, btw...what's that third assembly to the right of the blue and white flush tower? In my unit the black hose from the fill valve runs across to a connection to that third assembly. @2:18 your index finger is pointing at that third assembly. I called American Standard and they say their manual ONLY shows the fill valve on the left, and the flush tower with the blue and white buttons but nothing else.

Hi Fernando, I have the same model and it keeps making a foghorn like sound after flushing. Any idea what the issue might be?

Useless - what are the adjustments for???
