Boiler relief valve lifting or weeping

1Undersized expansion tank?

•Insufficient allowance for expansion on the boiler side can cause the boiler pressure relief valve to lift.

•The additional quantity of boiler water contained in the outer tank must be considered when sizing the boiler side expansion tank.

2Faulty boiler expansion tank?

•Is the expansion tank defective, waterlogged or improperly charged?

•Check for failed gaskets or bladders, or a faulty Schraeder valve.

•Use a tire gauge to check the charge pressure of the tank.

•Turn the boiler limit up to a higher setting and let the system run at a higher temperature. This will simulate maximum expansion in the boiler system.

•If the boiler relief valve lifts and/or there is a significant increase in the boiler system pressure, the expansion tank is flooded or undersized.

3Faulty boiler relief valve?

•Is the boiler pressure relief valve functioning properly? Dirt and water deposits can accumulate under the valve seat.

4Faulty boiler fill valve?

•Is the valve filling to the correct pressure?
