    Do you have a one pipe mono flow system?? Could be…….search this site for that method.

    And the items you referred to as "valves" are flow control check valves to prevent gravity flow in a zone when pump is off.

    I forgot about this place. I was searching on DIYChatroom for this thread bc I honestly forgot this place existed. I had a few r22 AC issues with my high velocity systems over the summer, but was able to handle them DIY.

    And I STILL didn’t get that triangle tube combi 155 even hung on the wall yet. Back yard redesign and this project are the two that I was supposed to get done over the summer and did not. Now the heat is on with the old system.

    And it looks like my fear of draining the system will be gone shortly, bc at this rate, without the inlet water on, the bad bell & Gossett bearing is losing ~3 gallons per day. I estimate this bc I emptied the paint bucket around midnight and it was 1/2” from the rim at 8 am. It’s going to drain itself, and I will have to put in one of those taco pumps. Well, I do need to assure the system is flushed before connecting the new boiler.


    I decided to go out the basement window that’s already been used for a dryer vent. I am redesigning the laundry room now and still choosing the heat pump water heater. 80 falling will simply not fit. So 40, 50, or 65 gallon are my options for the low ceiling room with a floor above that I plan to re-do, making for easy airflow. I guess I could put the water heater in the main room and duct it. So that might enable the 80 gallon and also just be a bit smarter for service than a tight closet in the basement.
