How It Works Inside Your Water Purifier
Role in the Purification Chain
The electronic gatekeeper of your water purifier. When the storage tank fills or power turns off, this 24V solenoid valve snaps shut instantly, stopping raw water from continuously leaking down the drain 24 hours a day.
Physical & Mechanical Principle
An electromagnetic copper coil pulls an internal stainless steel plunger against a food-grade rubber diaphragm. When energized by 24V DC, the valve opens to allow flow; when power cuts off, an internal spring snaps the valve hermetically closed.

How to Spot Genuine vs Local Copies
The Phantom Membrane Leak
Homeowners notice wastewater continuously draining into the sink even when the purifier is switched off, and technicians falsely claim the membrane housing or pump is broken, demanding ₹1,800. In reality, a ₹150 Solenoid Valve simply has dirt trapped under its rubber diaphragm.
Turn off electrical power to the purifier. If waste water keeps running down the drain while power is OFF, your Solenoid Valve is stuck. Lightly tap it or swap it with a fresh valve.
5-Minute Step-by-Step DIY Installation
Unplug Power & Close Tap
Shut off raw water inlet and disconnect purifier power plug.
Disconnect Two DC Wires
Pull off the two spade connector terminals from the old SV.
Release Tubing
Press collet rings and withdraw the 1/4" inlet and outlet tubes.
Insert New Valve
Observe the embossed flow arrow on the SV body. Push tubes 15mm in and reconnect the two DC wire terminals (polarity is interchangeable on AC/DC coils).

Frequently Asked Questions
Does wire polarity matter when connecting a 24V Solenoid Valve?
No. Solenoid valves use an electromagnetic coil without fixed polarity. You can connect either wire to either terminal freely.
Why does water drain when the purifier is turned off?
This is the classic symptom of a failed or stuck Solenoid Valve. Raw water bypasses the open diaphragm under mains pressure.
