main return line traps

pugdad

Hello looking for some advice on location and type of trap to install . have a two zone system blowing steam from condesate tank vent usally when only 1 zone is calling .there are 4 11/4 return line on each zone they drop out of crawl space aprox 4 ft and tee into single 11/4 line on each side to condesate tank . could a trap be installed on each of the two lines or would they need to be 8 traps one each of the returns prior to merging

Bad traps

The problem must be further upstream, as no steam should come out of the returns from the radiators. Check all the radiator traps, and see if your problem is from higher up.--NBC

Take a picture

of one or more of your radiators and post here- let's see what you have.

I'd be willing to bet

you don 't need that condensate tank at all. Gravity return worked for the Dead Men......
