Lubrication system for marine or RV toilet

A combination of a manual lubrication system and a manual toilet flush pump for a manual toilet, the manual flush pump being located to one side of the manual toilet and having a linear reciprocating operating handle having a generally vertical operating axis, the manual lubrication system comprising:

• a lubricant reservoir affixed in a generally parallel fashion to a housing of the manual flush pump laterally opposite the manual toilet, the lubricant reservoir being at least partially translucent and a lubricant therein being colored so that a lubricant level can be visually gauged;
• the lubricant reservoir including a manual lubricant pump assembly with a movable lubricant pump head having an operating axis generally aligned in spaced parallel fashion with the manual toilet flush pump operating handle operating axis, the movable lubricant pump head movable in a linear reciprocating fashion relative to the lubricant reservoir and the manual toilet flush pump on the toilet to pump a small, consistent quantity of lubricant from the lubricant reservoir with each stroke;
• the movable lubricant pump head comprising a lubricant outlet connected by a flexible movable lubricant feed line to a fluid connection in a flush water feed line for the manual toilet flush pump between a clean water supply and the manual toilet flush pump;
• and
• a manual shutoff valve in the flexible movable lubricant feed line between the movable lubricant pump head and the fluid connection in the flush water feed line.
