Description

This is the 1/2 psi pressure switch used on the Delta UV unit. Our records list it as Neptune Benson part 70-02315 and also reference it as 1000-2561, so check both numbers against the switch you are replacing.

What it does

The pressure switch confirms that water is moving through the unit. That signal is what allows the system to run, and it is the reason a UV unit will not fire when the pump is off. When the switch itself fails, the unit stays dark and the symptom looks far worse than the part.

Before you order

The setting is 1/2 psi. Compare the number printed on your existing switch to both references above, and confirm the unit is a Delta UV before ordering.
