Thetford Hand Sprayer Leak/Fix
Today I discovered that the hand sprayer for the toilet would leak when operating the pedal flush mechanism. We were using the on board water system, so pump pressure levels and only leaked when flushed. I removed the hand sprayer from the tubing and determined that if the lever was not pressed, there wasn't a full seal. At first I figured either the spring mechanism was bad or maybe a gasket seal. After closer inspection I figured out how to disassemble it. Since I didn't find much about this online, I'd thought I'd share it here.
On the face of the sprayer, the small center protrusion is a cap that was easily removed with my fingers. Behind is a 3/16 Allen head that will remove the aerator. Removing the aerator reveals a plastic piece with a view of the pin and gasket that moves with the operation of the squeeze lever. There was a small piece of plastic debris that was lodged in there preventing the mechanism from fully sealing. Using some needle nose pliers I discovered that the plastic piece that surrounds the center pin/gasket is also threaded. Once this final piece was removed I was able to rid any foreign objects and re-assemble. So far it seems the proper function is restored. In hindsight I should have photographed the process. I searched for some manuals or schematics online that might show some of this, but came up empty handed. Anyway, I suppose if you find yourself with a leaking hand sprayer you might try and take it apart.
Cheers!
