Kohler K 3658 7 does this toilet have a standard fluid flush valve

Asked by: Anonymous
Hello, my name is Elissa with KOHLER Customer Service. I would be happy to help you with your toilet question. The 3658-7 has a canister flush valve. It does not have a standard fluid flush valve. Technology: Single-flush gravity uses the force of gravity and a precision-engineered tank, bowl, and trapway to create a strong siphon during flushing. Class Five® flushing technology offers plug- and leak-free performance, extraordinary flushing, and better rinsing power for a cleaner bowl.

Highline 2-piece 1.28 GPF Single Flush Elongated Toilet in Black Black is rated 4.2 out of 5 by 41.

The ada comfort height is a big plus since I had spine surgery. It makes all the difference in being able to stand up from bowl on my own. Easy installation, A real pleasure to install, The flushing system is fantastic. Had the bowl for 18 months and flushes great every time. To get an elongated comfort height bowl in black at this price is the steal of the decade. The low flush rating of the bowl is fantastic with great flushes all the time.

Rated 1 out of 5 by from Broken toilet. Toilet came I'm with a broken bowl. I wanted to reorder and bring in just that piece. I'm lazy. Manager said no I would have to return it all then reorder. I told him if I bring it all there will be no reorder. He said he understood. So I went to lowes and ordered my new toilet.

Rated 5 out of 5 by from Very pleased We didn't do the installation but that seemed to go well. The product itself is wonderful. We love the comfort height and the water savings. Even though it uses much less water it flushes with plenty of force to do the job. The color was perfect for us.

We bought the color "biscuit" to be just off-white. and were surprised to not be able to find a matching color lid -- we settled for "bone" lid which was close. If could have found matching lid, would rate 5 stars.
