  Refilling of Tank

Refilling of water tank can be carried out at any time .  The TRX high strength glass tubes are well tempered to handle thermal shock due to the difference of water temperature during refilling , even it is done at the heat of the day.

The TRX basic system can be converted to fully automatic control system with a 3rd party controller , or with a simple adjustable pressure-tank ( see the left diagram ) to have auto stop function during refilling .
