2

Follow the connection method required for the component and avoid forcing plastic parts or tubing.
3
Test Operation
Restore water and confirm the valve, timer, or drain connection functions correctly without leakage.
Good to know
RO control parts are system-specific
!
Verify tubing size1/4″ and 3/8″ OD components are not interchangeable.
!
Check system designTank-based, tankless, countertop, and drain-line configurations can require different parts.
Source correction: the current page says the included 3/4″ × 3/8″ adapters are “for 1/4″ OD tubing.” That parenthetical is inconsistent with the 3/8″ product and adapter size and should be removed. Use this timer as a convenience shut-off device, not as certified flood-prevention equipment.
Not sure this is the correct RO part?Send your system model and a clear photo of the existing tubing or connection.
