What if the Riser Center to Center Distance doesn't match
the Pre-Assembled Valve Station?
If the dimension correction is within +\- 1/4", then adjust the
valve station by adding or subtracting spacer flanges
What if the Risers Aren't Level?
A - Readjust the risers by cutting and reworking them.
B - Use a set of Alignment flanges available from Clarke Sales.
How do I Orient the Holes on the Riser Flanges?
The hole pattern should always straddle the line between the inlet and
outlet flanges.
How much clearance to the walls do I need?
See the Certified Prints form Watts submitted by Clarke Sales for
clearance details.
You may put them on the in and out Point of Connection per district
practices.
How do I Prepare for Combined Irrigation and Domestic Valve
Stations?
Usually a small RP backflow preventer can be installed on the outlet
leg of the valve station using the supplied 2" header tap.
The contract C-516 specifies 10 days between order approval by Clarke
Sales and the delivery to a specified LAUSD site.
