onnecting assembly

 that connects the above level control valve to a garden hose;  

7. Garden hose (customer provides) 
 

 

Autofill components from a building with a no-leak hose bib (left) to an outdoor MyGarden (right): hose bib (not 
shown, customer responsibility); splitter (allows Autofill to share the hose bib); timer (takes over the on/off function 
from the hose bib; garden hose (not shown, customer responsibility); level control valve (installed inside the 
Reservoir) 
 

The hose bib 

MUST BE

 leak-free because it will be permanently open with water flow controlled 

by the Rainbird timer. Small leaks may be stopped by wrapping Teflon tape over the bib threads.   
As a last resort replace the bib.   
 
Install batteries into the timer and program it per instructions.  With medium leaf area setting the 
timer to refill the reservoir once daily is adequate.  Large leaf areas e.g. several giant tomato plants 
growing over the Overhead Rack, you’ll need to re-up the reservoir twice daily. We suggest on for 
2 minutes at approximately noon and again at 4p.  This becomes easy with practice.  And you 
cannot overfill the reservoir because it’s the Level Control Valve in the reservoir that shuts off the 
water even when the timer is on.   
 
Screw the splitter onto the bib hand tighten only.  Screw the timer onto one side of the splitter.   
Now with the timer controlling on and off open the bib handle about ¼ turn. Now under pressure 
the hose bib / splitter / timer connections 

must not

 leak because they’ll stay pressurized 

continuously 24/7. Note – leaks beyond the timer for example a rare hose burst are not problems 
because 1. The bib is only opened a quarter turn, and 2. The timer will allow for flow for only 
several minutes daily.
