  • I have lever valves, so how can I determine where my return valve is?  Thanks.

  • @daleftybandit Hello;

    Give me a little more info about your valves you are talking about.Lever valves...Do you mean ball valves?The pipe that goes into the bottom of the Boiler is your return line. Follow it up and you will find one or more valves on the return line. There should be a sediment faucet there. If you hook the lever on the end of the zone valve you will allow water to go into that loop. Open one sediment faucet until you find the one that corresponds with the zone valve.

  • Hi Theoldkid888, enjoy your videos, can you tell me if I need to drain out my hotwater baseboard system, if I plan to add a new five foot secton? is just in series right? thanks

  • @shaqmoney2001 Hello there; That is correct. Baseboard radiation is usually looped from one room to the next. If you are going to add another 5 foot section, you will have to purge that zone (loop).One of the big mistakes made by many people is that they don't put in enough radiation. I generally try and go with 1 foot of radiation for every 10 square feet of floor space. A room 10 x 10 would then have 10 feet. Hope that helped. Thanks for your comments and enjoy your day!!! Al

  • I've got it... I understand. A bit tricky at first.. But then once I took my time, and watched your video several more times... I've identified the return valve. What I meant by "lever" valves was, they're not circular, but a "stem" if you would...you know? With red plastic covers on them...Sorry maybe that's not the right name for them, they just look like they'd be called "levers"....Thank you SOOO much for your guidance in the video and your quick response back AL....PEACE.

  • Hi theodkid888,great videos, If I want to purge the system to add another section, do I have to shut the feed that is just before the pressure reducing valve so that the system is total dry before cutting into it so that I can sweat the pipe? and follow the steps above. shut feed,shut return, and open zone valve then open the drain valve to purge right? thanks in advance.
