meter or more.
2) CA type check valve can be connected to
either tube or threaded pipe of R1/2 and
R3/8.
3) Stainless steel check valve CS type has the
connection of RC1/4 or NPT1/4 for pump
models EH-E30 and 35SH, and RC3/8 or
NPT3/8 for pump models EH-E45 and 55SH.
For the connection of pipe, apply seal tape to
