Strainer servicing notes
The strainer cartridge can be cleaned without removing it from the Y-strainer body:
Opening the drain valve (cod.
538202 FD - 1/4" NPT; 538402 FD-1/2" NPT optional) and allowing
the dirt to blow into a drain line.
Backflushing it (having the water flow backwards through the screen). This is done by closing the
supply isolation valve before opening the blowdown valve.
