1-pipe line blockage

Possibly a sagging horizontal feed instead of blockage. If it is, the hose will do you no good. Examine all the pipes first for porper pitch.

1-pipe line blockage
i have one radiator fed by a 20 ft.x 11/4 riser which has a couple of short horizontals sections of pipe in it.the riser bangs so i think there is a partial blockage preventing the pipe from draining.
do you think i could attach a hose to the air vent tapping and flush the riser out with gentle hose pressure? one horizontal section is under the floor and the other is in the basement , so this is an alternative to cutting into the section i can get to and cleaning it out that way.unfortunately there is no union so i would have to saw the pipe out and pop the leftover threaded pieces out from the elbows without a lot of room to work between pipe and ceiling. any thoughts??--nbc0 -
banging rad
you need to raise the rad to get rid of sag in pipe use tiles or wood pieces make sure vent end is higher0 -
i-pipe blockage
the radiator has been raised up 1/2 in. and slope checked.the visible horizontal run in the basement is also sloped reasonably well.
that's why i thought of a blockage--perhaps from 1999 when i put stop leak in the old american standard to "get me through the winter"[which i did 7 more winters before puting in the new peerless 211 a!!] this riser is the first off the main from the boiler so it could have "inhaled" the boilover of the stop leak.0 -
Banging riser
Had that before. If the horiz pitch is OK, perhaps the rad is venting too quick. Have you tried slowing it a bit?
NOT at the hand-valve(should be wide open), but the venting rate itself.0 -
blow it out
Blow out the line with CO2. did it ever work correctly ?0
