Toilets
Electric rim wash valve guidelines (inside toilet)
•
1/2" NPT connection
•
1/2" plumbing to the toilet. If using a single water supply line, this 1/2" branch must intersect
with the main 1" distribution line prior to the electric high-flow water valve.
Electric high-flow water jet valve guidelines
•
Electric high-flow water jet valve and maintenance ball valve supplied with every toilet
•
1" NPT connections
•
Place water jet valve closest to toilet and the maintenance ball valve farthest from the toilet
–
Refer to direction arrow on top of the water jet valve inlet port
•
In-line strainer factory-installed in the water jet valve inlet
–
Cone shape protrudes out against the direction of water flow, away from the center of
the valve, and is pointed towards the maintenance ball valve
•
Water jet valve has a small white manual override lever located by the solenoid:
–
Place in vertical position for correct electrical operation
–
Place in horizontal position to manually test the water system
Discharge plumbing guidelines
•
Keep all lines as short and straight as possible
•
Minimum downhill slope required: 1/8" per foot
•
1-1/2" ID pipe or 1-7/8" ID hoses required
–
For 1-1/2" pipe:
•
Requires drain, waste, and vent (DWV) pipe fittings with sweeping changes of
direction
•
Do not use schedule 40 or 80 fittings with tight turns
•
Install unions, as necessary, for service
–
For 1-7/8" hose, eliminate hose sags and low spots
Check valve guidelines
•
Flapper style supplied with every toilet
•
Spring check: 1"
•
Install valve:
–
Close to the toilet
–
On the discharge side of the toilet plumbing
–
Before the waste line joins with any common discharge line
–
When open, the flapper "hinge" must be at the highest possible location
–
So the flapper opens in-line with the direction of the water flow
•
When gluing the valve in place, do not allow excess glue to contact the flapper
•
When flushing overboard through the seacock:
–
Loop inside the toilet must be above the waterline
–
Seacock must be 1-1/2" full-flow and located no lower than 12" below the water line
