4-way reverse osmosis valve

4-way reverse osmosis valve. Tubo de conexión 1/4"

This part is a hydraulic shut-off valve whose function is to stop the purification system when the accumulator tank is full, which means that if there were a fault in the 4-way osmosis valve, the equipment would not stop expelling rejection water because it did not it would stop producing, which would damage the membrane.

In addition, as there is no control in the water inlet volume, it is possible that not all the water passed through the reverse osmosis membrane, so untreated water would leak out, contaminating the treated water again.

If you have noticed that the equipment does not stop expelling water into the drain, it could be a problem with the 4-way osmosis valve. In this case, replacing it would be enough.
