Toilet Types


Two Piece Toilet
A two piece toilet is made of two separate pieces of vitreous china, a holding tank and a bowl. The holding tank is mounted on the bowl by the installer using washers, nuts and bolts. Two piece toilets are often called "close-coupled" in reference to this mounting system and are the most common toilets on the market. The Flushmate model number for this type of toilet always begins with M-101526.

Converting regular ol toilet to power flush toilet
Jacob (GA) | November 16th, 2020
Hello, Will this product convert a standard toilet to a power flush toilet?
Note From Store Owner: Jacob, The Flushmate System requires a specially designed pressure-assist fixture and is not retrofitable to a gravity toilet. Flushmate is available with all the major toilet brands and available for home delivery ( https://www.eflushmate.com/category/Toilets.html ) or visit https://www.flushmate.com/distributors for local distributor.

Tech support was great, product installed easily and worked as stated. Sales team took a while to get back to me (room for improvement).

Great Replacement
Robby (IL) | March 25th, 2020
I had a very positive experience with the company and product. I called because I was not sure the kit to replace my old system had everything I would need. A helpful engineer told me it did and transferred me to sales where I placed my order. The unit arrived two days later and was easy to install. This is a much better system that what we had previously and it is well engineered.

Bert (CA) | November 27th, 2019
Included instructions were only text, and somewhat confusing. Pictures or a diagram would have helped. I initially installed the main rubber gasket above the three-inch nut, and of course it did not work. Once I put it together properly, everything is fine.
