baseboard radiators not draining
Hello, I went to service and clean my boiler. Steps taken; turned off power, shut the water off, hooked up a hose to drain the boiler and opened it. After water stopped coming out of the hose and the boiler cooled down, I proceeded to clean the inside of the boiler and finished the rest of the service. filter, nozzle etc.
I had to move one of the bleeder valves on a basement baseboard it was facing the pipe and couldn't fit a cup to catch water when I went to bleed it. When I opened the bleeding valve water shot out from the top, I found the screw and finally got it to go back in. I have a single zone system, 6 radiators on the main floor and 2 in the basement. My questions are why didn't the basement radiators completely drain and second, how do I go about draining them? Thanks in advance.

j,
My first question is why did you drain the system to clean the boiler. It's unnecessary and introducing fresh water into a heating system is the worst thing you can do. Unless you have to repair a pipe or have to drain for another reason you never drain your system.
Once you get the all the air out and have what we call dead water you leave it alone.
As far as draining the basement rads they are most likely below the height of the spigot used to drain the system and water does not flow uphill.
Unless provisions were made, like drawoffs on the rads themselves you are going to have to add them somehow.
Pics would be helpful if possible. Hope this helps a little.

hi, tks for responding. had to replace some bleeder valves. two on the main floor and one of them on basement rad. so it just fell into I'm here doing the cleaning, oil fitter, nozzle. let's just get this done too.
yea I now get the basement rads are below the height of the spigot used to drain the system. no nothing on the rads except bleed valve. I eventually found a rubber hose that somewhat fit and placed it over the spout of the bleeder valve and kept filling a 2-liter bottle.
with everything, I was doing, the unexpected shower i had just threw me. but yes this does help, and i do appreciate your responding to me.
