How To Change a Pressure Gauge on a Pentair Triton 2 Sand Filter

In this "how to" we will guide you through how to replace the Pressure Gauge on a Pentair Triton 2 Sand Filter. After use, the pressure gauge on your pool filter may be damaged to the point it is unreadable or inaccurate. 

1. ORDER PARTS - Order a Pressure Gauge to have it on hand to replace the broken Pressure Gauge. This picture shows where the Pressure Gauge attaches to the end of the Air Bleeder Assembly.

2. TURN OFF PUMP - Before you remove the broken Pressure Gauge make sure you TURN OFF the pool pump.  For maximum safety turn off the power at the circuit breaker to the pump.

3. RELIEVE PRESSURE - Next you will have to relieve the pressure that builds up in the filter during operation. To relieve pressure turn the relief valve knob on top of the filter counter-clockwise. Water may spray out initially as you see the pressure on the pressure gauge go to 0 psi.

4. REMOVE PRESSURE GAUGE - The Pressure Gauge is located on the end of the Air Relief Valve on the Pentair Triton 2 Sand Filter. Twist the Gauge off in a counter-clockwise direction. If it does not turn easily, use an open end wrench on the brass nut at the base of the Gauge.

5. TAPE THREADS - Put 2-3 layers of plumber's Teflon tape on the threads of the new Pressure Gauge. Wrap the tape in a clockwise direction so it will stay on as you screw the Gauge on.

6. SCREW ON PRESSURE GAUGE - Thread the Pressure Gauge into the Air Relief Valve in a clockwise direction. Use an open end wrench to tighten the last 1/2 turn. Do not over tighten.

7. TURN ON PUMP - Turn ON the power to the pump at the breaker box.

8. CLOSE RELIEF VALVE - When a steady stream of water shoots out of the Air Relief Valve, close the Valve.

9. CHECK READING - Check the pressure reading on the Pressure Gauge. It should read about 10-15 psi. Turn the front dial so that the "Start" arrow lines up with the current reading. When the pressure moves up to "Clean Filter", it is time to backwash your filter.
