What is the safe pressure for a hot-water-heating system?

Dec 08, 2002 · Back pressure.Like in a constant pressure feed water system where you want to maintain a set pressure in the feed header.That pressure is generated by the pump, but regulated by a valve that bypasses excess feed water back to the DFT thereby creating a 'back pressure'. When the boiler calls for water, the boiler feed valve opens and the resulting drop in pressure causes the back pressure valve to close reducing the amount of water returned to the DA tank.
