Hydrophore unit trouble shooting

Problem

Cause

Action

Hydrophore pressure tank being under charge.

In this condition, the water level is more than 3/4 parts of the tank volume. The problem can be found with no water supply at the accommodation top.

Air is leaking from either relief valve, isolation valve, air supply valve, vent valve or the gauge glass itself.

Temporarily you can fix this problem by switching pump to manual and drain the excess water or utilizing in engine room. Once the water level reach the 3/4th of the tank volume crack open the air supply line to charge it with compress air. Once the pressure reach pre-set value, stop the compressor and put the pump back to auto. But for long term solution, you have to apply soap solution on all joints and key leak point. Once leak detected stop and de-pressurize the system and rectify the fault.

Hydrophore pressure tank being over charged.

In this condition there is more than 1/3rd of the air volume at the pump cut out pressure.

The situation can result into no water in hydrophore pressure tank.

Air leak from air supply line or the valve itself slowly filling hydrophore pressure tank with more and more air.

At first crack open the vent valve and letting some air go. Then when the air pressure reach value based on its cut in pressure close the vent valve and switch pump on auto.

Make sure that the pump cut off at pre-set value otherwise the system needs immediate maintenance. In long run prepare the system to be de-pressurize, open air supply valve and overhaul it.
