The factory setting for a water feeder/ pressure reducing valve is typically what pressure?

The factory setting for a water feeder or pressure reducing valve is usually set to 15 psi. This standard pressure is established to ensure adequate water supply while preventing excessive pressure that could lead to leaks or damage in the plumbing system. Setting the pressure at 15 psi strikes a balance, providing enough force to ensure that water moves adequately through heating systems or appliances while protecting components from high-pressure situations.

This pre-set pressure is often recommended for residential heating systems, ensuring that the boiler receives a proper water level without unnecessary strain. Understanding this factory setting aids technicians in effectively troubleshooting and adjusting systems to maintain optimal function, making knowledge of this standard essential for anyone working with oil heating systems in Maine.
