View Full Version : [HELP] Installing toto washlet on existing toto aquia II toilet

03-08-2012, 04:25 PM
My plumber and I are trying to install a TOTO SW554-01 Washlet S300 on a TOTO CST416M Aquia II Toilet
It seems to be impossible. Because the Toto Aquia skirt wraps around and hides the connections where the junction valve from the washlet should be. Now we are stuck.

Is there an extension to connect the junction valve for the washlet to the water supply and goes to the toilet.
If so, does the junction valve just "hang" only connected to two water supply hoses?

any tips or help greatly appreciated!

It's a THU9090 Washlet adapter extension.
Basically, it's an extension from the tank that allows the tee valve to be out in the open. The tee threads onto the end of the extension, and the supply to the bottom of the tee.
