Description
This is a description of a shut-off block for a reverse osmosis system. The block will automatically shut off the water supply when the tank pressure (or permeate pressure) reaches a certain level. This is helpful in preventing the system from wasting water even when the tank is full.
Available in 1/4" with quick connect and 3/8" with compression nuts (see pictures).
Automatically shuts off the water supply when the tank pressure (or permeate pressure) reaches ~65% of the incoming line pressure.
Without a shut-off block (or solenoid in case of RO with pump) the RO would be wasting water permanently even when the tank is full.
