Secondary LWCO?

ChrisJ Member Posts: 11,966
Does anyone know if some areas require a secondary LWCO and if so what is the typical way of doing it?

I am planning on using a probe type LWCO such as a Hydrolevel cycleguard.
Single pipe quasi-vapor system. Typical operating pressure 0.14 - 0.43 oz. EcoSteam ES-20 Advanced Control for Residential Steam boilers. Rectorseal Steamaster water treatment

    The only time Ive seen secondary LWCO on steam is on commercial work. Those manufacturers give you secondary tappings off the boiler. I dont know why you would want one on a residential system. If the boiler is maintained properly, and the LWCO is blown down regularly, ( float type) you should not need a secondary.

    manual reset

    Hello   Its best to check your local code as different states and counties have different codes....its useless to have two lwco unless the second one is required and usually if it is its a manual reset..meaning you need to check your boiler before putting it back in operation...It generally goes by boiler size not where its installed....Hope this helped   J A
