Richardson system

I have replaced the boiler on a Richardson system, Do I need to have a check valve in the wet return? Also, if I add radiation, do I have to use Richardson valves & traps on the radiators?

    Don't need a check valve

    the Hartford Loop does that job a lot better.



    Richardson fittings aren't made anymore. If you can get MEPCO or Barnes & Jones orificing valves, they are the best choice. Use Hoffman 17C traps on the returns, their relatively low air throughput is the closest match for the Richardson ells.

    Have a Richardson

    We have a Richardson System which had 3 add-on radiators back in the 30's.  The add-ons have traditional packless, graduated valves and traps.  PIping was altered to remove checkvalve and add Hartford loop.  For the most part the system works well, though I would love to convert added rads to Richardson, so if ever you come accross or decide to remove fixtures keep me in mind. 

    P.S.:  Dan had some information in an old Hydronics Magazine article "Dealing with the Richardson System" and I believe he addressed just what you are dealing  with.  Try contacting him to get info, or it may be in resource section of this site.
