2 Features Included In This Product Explained

Horizontal Outlet

When the pan has piping at the back, inside the wall, it is called a horizontal outlet toilet or pan. As the cisterns are concealed or placed against the wall, most plumbing is hidden out of sight.

Vertical Outlet

It is a toilet where the plumbing exits through the floor. In certain scenarios, these toilets may need to be installed a few inches higher than the surrounding floor to accommodate the plumbing.

Stuart Asked :
I forgot to ask if Horizontal Flush plates operate with the uniset cistern, as it states vertical and horizontal use but doesn't state if it's referring to flush plates. I want to purchase the Grohe - QS-V7981 38642001, and I'd like to purchase the QS-V29159 -£74.42 Vertical Flush plate. I noticed the following flush plates, but I'm unsure of the difference apart from the cost. Please advise if the following plates are compatible with the Uniset cistern. QS -V75919 - £184.34? QS- V28547 £104.63?

Answered By QS Team

The flush plates can be either vertical or horizontal in this cistern. This, however, needs to be determined before the tiling, as the inspection box needs to be positioned in the desired orientation. 38805000 would be compatible with this cistern.
