Is this work with TOTO CST 853 toilet?

Asked by Murausa April 27, 2020

Answers

I believe it works with all toto toilets. The height is adjustable and that seems to be the main difference among the Toto tanks. . It help to adjust to the correct height and put in the white stop before so it stays at that height when you go to install it.

I know it looks exactly like the cheaper white Korky valve (instead of blue Toto original), but I can confirm I bought a cheap white one in the past at the same time as an expensive blue one, and the expensive blue one outlasted the cheap one. $15 extra is not much to pay for when the slow leak the cheap white one caused for days until my utility notified me of continuous water use probably costed more than $15 in water costs. This one also lets you adjust the amount of water that flows out to the bowl, where the cheap white one doesn't.

Easy to install. Clear directions. Needed an adjustable pliers to loosen the existing nut on the bottom outside of tank and I used a razor blade to shorten/cut the water fill tube to the correct length. The new outside nut was hand tightened.

My original Toto valve lasted for 8 years and I'm hoping that this one will last the same or longer.

The rubber washer in my 22 year old supply hose was too hardened to reconnect leak-free, but this kit even includes a replacement washer! Other than that, it was an uneventful install and restored the fast tank fill.
