Bleeding hot water baseboard??

Question

I need to drain our baseboards to move some pipes. How do I drain it properly and when I am done how do I get water back into the pipes? Thanks for any help.

So to put water back into the pipes will it refill itself or will I have to connect a hose with a water source and refil it this way???

Answer 1

Been there and done that... Really not as complicated as you may think.

I've expanded my system from three zones to six and had to run new lines. Pictures and explanation on draining and bleeding the lines can be found on my web page. Contact info is there if you need more help.

There should be a connection on your furnace to the cold water pipe entering the house. It should have a ball valve followed by a one way valve and then a pressure reducer. Turn off the ball valve before you open the pipes to prevent water from flowing through the system continuously. Put a hose on the drain opening and relieve pressure. It is unlikely that you will be able to remove water from the entire system in this manner. I had to cut the plastic PEX pipe and catch the water in a bucket. Once everything has been put back together open the ball valve and let water flow into the furnace. You need to bleed air from each zone separately. Any small bubbles remaining will eventually find their way to the purge valve and be released. Check the pictures of my furnace and compare to yours. The layout may be different, but overall operation should be similar.

The circulate of the water is meant to delivery the bubbles to an computerized bleed valve, this is fastened on an air separator. The bleed valve has a drift that hangs down into the air separator. whilst it get low, that opens a needle valve and we could some air out. in case you have extreme mineral content textile on your water, a number of that could have clogged the valve. if so, it needs to get replaced. If this description would not tournament your setup, then in the accepted experience, you prefer a thank you to get the bubbles to the bleed valve.

if there are valves to shut off the loop that you want to move, then shut them off first. then if there is a boiler drain on that loop just hook a hose to it and open into a bucket or a drainpipe. move what you want . then to put water back in, close boiler drain, open shut off valve on opposite side of boiler drain, when no more water goes in line, check for air or water leaks, at new solder joints, if none , open boiler drain, when a steady stream of water comes out hose,(no air). you just shut boiler drain, and open other shut off valve. this will take out air , repeat as necessary.
