Hi.  We are traveling (working trip) and have a toilet leak. Porcelain toilet leaking at rear base but not at connection.   Leak happening at what appears to be plastic possible pressure valve at base of toilet.  Of course only happens when pump is pressurizing system but is steadily becoming worse. 

What does that base connection do? Is it repairable? Thank you so much.

That is the fresh water supply to the toilet for filling and flushing. It has a standard residential style compression fitting. You can carefully tighten it a little, no more than 1/4 turn, and see if the leak stops. If not you need to remove the line, cut off the very end and install a new brass compression sleeve. There should also be a metal sleeve Inside the tube to resist the deformation of the plastic pipe when you tighten the nut. It could have been left out. All these parts are available at any hardware or box store.

Have you tried turning off the valve? This one has no line coming out the top because there is a composting toilet. If it leaks when turned off the valve seal has failed and you need to replace the entire valve.

Thank you John.  You are always a wealth of information.  

This happens to be leaking at the base of the toilet where it connects.  It appears there is a small 3x3" valve that the fresh water connects to at the base of the toilet.  It doesn't appear to be leaking at the connection of the line itself, it seems to be leaking from a valve maybe.  We don't think its leaking from the inlet hose.
