My toilet installed in basement.

Not lighting related, but I thought I show this because of the other toilet related image I saw posted.

This is a Kohler Wellcomme toilet from 1986 that I installed here in my basement, as you guys don't know all that much about toilets, I will explain some things.

Previously, there was a tank toilet that was installed in here, and then I did some pipework behind the walls to convert it into a Flushometer commercial-type toilet. As noted these types of toilets are not usually installed in homes because of restrictions and limitations. I got lucky that it was possible to install one here. In the next room over I installed an expansion bladder tank to make sure the pressure is maintained when flushed and doesn't take a whole bunch of pressure for the rest of the house.

These Flushometer valves are designed to take water directly from the water mains and flush the toilet. Toilets usually have tanks because toilets are a siphonic design, so it needs a large amount of water in a short period of time to trigger the siphon effect and empty the bowl, and in residential applications it usually is very hard to accomplish. In my house, the whole house plumbing is run in by a single 3/4 inch diamater pipe, which really restricts and limits that, I mean when everything else is shut off in the house, the toilet will flush fine from the mains even with a 1/2 inch diameter pipe. One advantage is this toilet get the first priority out of any other fixture in the house for the plumbing, as it is the first thing that is fed from the pipe line.

The expansion tank is what helps maintain the pressure, as it has a bladder in it with air and it acts like a spring and stores water. So when the Flushometer is off the tank is filled and when you flush the toilet, the tank empties and the bladder expands letting the water out of it and keeping pressure, so when the flushometer is running it's short flush duration, very little water get's diverted into the tank while the tank empties.
