Aquasource One Piece Toilet 3” flush valve repair

[Steve42]

Let me begin by saying I know this isn’t a quality product and I should really replace it. I plan to, but we just had a separate issue result in a flooded basement and I can’t deal with a two-front battle.

Our master bathroom toilet has been running and flushing. My wife asked to have the plumber who came out for the basement look at it and he theorized the flush valve was broken. I took it apart tonight and discovered it was actually just missing a part.

It uses two machine screws and two brass pieces to clamp the flush valve down to the opening in the bottom of the tank.

The second screw no longer has a brass piece.

Because it’s Aquasource, it’s not an available part anywhere I can find. I’m going to try and have a friend machine me an aluminum replacement piece if I can’t find a new valve. Menards has a similar valve for a 2-1/2” version but I can’t find the 3” option anywhere.

Any advice until I can finish up the other repairs and buy/install a new toilet?

TOTO used a similar flush valve, and this is their new one that replaces it.

They have gone to three tabs instead of the two they used to have.

And the old one with two tabs and a flapper.

I looked for Aquasource parts and there really isn't anything to look at. WDI had a flush valve for a two-piece with tank, not what you need, same with Korky.

Thanks, Terry. My friend was able to fabricate a replacement piece out of aluminum in his workshop.

I’ll still be replacing the toilet, but hopefully this repair will last a couple of months while we recover from the basement damage
