[0197] A tankless toilet flush valve releases a force of water to the toilet bowl or urinal. As described above, to mix the flow of water with sanitizing cleaners located in the cleaning agent dispensing system, the water must bypass the vacuum breaker, flow into the cleaning agent dispensing system where tablets of sodium hydrochloride are located. After mixing in the cleaning agent dispensing system, the cleaning agent saturated water then leaves the cleaning agent dispensing system into the vacuum breaker adapter that leads the vacuum breaker adapter to the toilet bowl or urinal.

[0198] Although the above described embodiments use a flush valve adapter to divert water from the flushing system, the flush valve housing may include an outlet which is directly connected to the cleaning agent dispensing system.

[0199] As described above, the toilet cleaning system is configured to avoid tankless toilets flush valve diaphragms and pistons where the cleaning agent (bleach) will eventually destroy the critical working parts. The cleaning agent dispensing system and flush valve adapter, work in tandem, below the commercial valve diaphragm and piston style flush valves. This configuration prevents corrosive cleaning agent (bleach) from contacting the toilet's rubber components, safeguarding against potential damage caused by caustic cleaning and sanitizing agents.
