Backflow & check valves needed with boiler on private well.

OhioRuss Member Posts: 29
I live in a rural area with private well and septic system. I’m installing the Lochinvar combi with Alpha 2 pump to distribution manifold to cast iron radiators. I intend on using Califfe’s water treatment cartridge. Are backflow and checkvalves needed? Thanks. I truly appreciate all the shared wisdom

    whether it's code there or not,
    that or an isolated make up water system,
    definitely protect your well and domestic water.

    A simple dual check with a vent is pretty inexpensive. You really don't want nasty boiler water in your drinking water.
